How a Brick is Sustainable & What are the New alternatives available — Econaur

A recent question posed by our user — is a brick building more sustainable? While this may seem a simple enough question, the answers are really not as straight forward. It is true, the first thing that occurs in the minds of most people is that brick is natural and therefore must be more earth-friendly.
The foremost criteria for evaluating the sustainability of a wall or building envelope material is thermal insulation. This is measured by the unit R-value — which is a measure of how well a two-dimensional barrier, such as a layer of insulation, a window or a complete wall or ceiling, resists the conductive flow of heat. According to Inspectapedia, basic brick walls have an insulation value, or R-value, of 0.2 per square inch. Conventional 8-inch concrete block walls have an R-value of 0.08 per square inch. In general, the greater the R-value, the greater the resistance, and so better is the thermal insulating properties of the barrier. Therefore, this far, the brick is faring as a better performer.
However, adding a layer of insulation or an air gap greatly changes the performance of brick and concrete. It is common in today’s marketplace to have aerated concrete blocks or insulated concrete blocks that are readily available. Insulated concrete blocks can increase their R-value to about 1.2 per square inch, and aerated blocks can have R-values as high as 3.9.
Bricks, on the other hand, suffer since very few values adds are made to them to have new products which are easily sourced in our material markets. It boils down to know-how and masonry techniques. Using techniques such as the architects favorite ‘rat-trap bond’ can improve thermal insulation. So, what are these ‘bonds’ and what specifically is a rat trap bond?

A brick bond is the pattern in which bricks are laid. It applies to both brick walls and to concrete block and other types of masonry construction. There are many different types of brick bonds and each has its own look, installation challenges, and structural considerations. A ‘rat trap bond’ is a method of wall construction, in which bricks are placed in a vertical position instead of conventional horizontal position there by creating a cavity (hollow space) within the wall. Architect Laurie Baker introduced it in Kerala in the 1970s and used it extensively for its lower construction cost, reduced material requirement and better thermal efficiency than conventional masonry wall, without compromising strength of the wall.
However, no performance data exists on the R-value of a rat trap bond brick wall — this is an assembly not a product and therefore becomes a bit trickier to ascertain. But despite the lack of data, one can make the following assumptions with some surety — an aerated concrete block wall is a better performer than a standard brick bond wall and a rat trap bond brick wall is better than any type of concrete wall!

Perlcon Brickbond

So, the next time you are choosing to build, start with the fundamentals — brick may not always be the most sustainable, it has to have a right bond to give a great performance.
Brick is a natural, quality, user and maintenance-friendly product, that is durable during all phases of its life cycle. In the construction phase from the use of raw materials, production process to packaging. During the operational phase through comfort, maintenance, flexibility, and safety. During demolition through reuse and recycling of bricks.
Thermal comfort
The porous structure of bricks offers a huge advantage: the ability to accumulate heat. In winter, during sunny days, bricks can store heat from the sun and radiate the energy back when necessary. During the summer they can buffer the heat and thus avoid overheating of the building.
Bricks require no maintenance. After a while, external brickwork even obtains a certain luster. It adds charm to a residence. Because no maintenance is required, the impact of the building on the environment is much smaller.
Mechanical resistance
Bricks are very stable. Temperature changes do not cause them to expand or shrink. Because of this mechanical resistance, bricks are well suited for buildings of ten or more stories.
Fire resistance
Brick is a non-flammable and non-combustible material. It reduces the chances of fire. When exposed to fire no toxic gases are emitted. Often, after a fire, a brick facade is structurally still sound and can be incorporated in the renovated building.
Adaptable and flexible
Brick buildings are very flexible. During the construction process and the building’s lifetime, the layout of the building can be customized.

The decision to demolish a building is usually not because of the state of the external bricks, even if it is a hundred years old. Often the old structure no longer meets the current requirements and the decision is made to reconstruct the building. After demolition, bricks can be recovered and recycled or reused.
After removing the remains of mortar, bricks remain reusable for restoration or for new homes and projects. Recovered bricks give a building an exceptional appearance and character.

Because of their mineral structure, bricks from demolition sites can be used after recycling as:
* Filling and stabilizing material for infrastructure works.
* Aggregates for poured and precast concrete and mortar.
* Aggregates for calcium silicate bricks.
* Red “crushed brick” as gravel on tennis courts.
* Plant substrates.
Because bricks only consist of natural raw materials, they have no harmful side effects when they come into contact with ground or surface water.

Monday Flashback #26 — Bombay House, Mumbai — Econaur

In this week’s Monday Flashback we feature the Flashback Sustainable Story of Bombay House, Bombay House is a historic privately owned building in Fort, Mumbai, India that serves as the head office of the Tata Group.

Situated near Flora Fountain, it was completed in 1924 and has been the Tata Group’s headquarters ever since. The building is a four-story colonial structure built with Malad stone and was designed by Scottish architect George Wittet, who designed over 40 buildings for the group and later became the head of Tata Engineering Company Limited, now Tata Motors.

The building houses the office of chairman and all top directors of Tata Sons, the holding company. Core companies of the group-Tata Motors, Tata Steel, Tata Chemicals, Tata Power, Tata Industries, Tata airlines, and Trent-operate out of the Bombay House.

Bombay House — located on Homi Modi Street ((after the noted industrialist and banker associated with the Tatas) in Fort — was built on the two plots of land bought by Sir Dorabji Tata, the group’s second Chairman and Jamsetji Tata’s elder son, from the Bombay Municipality in 1920. The building was designed by the well-known architect, George Wittet, who was also the architect of the Gateway of India, the Prince of Wales Museum (now called Chhatrapati Shivaji Maharaj Vastu Sangrahalaya) and other iconic buildings of Mumbai.

The overhaul of the Bombay House office was led by architect and urban conservationist Brinda Somaya, of Somaya and Kalappa Consultants. In March 2014, it became the first heritage structure in the country to get a gold rating as a green, environmentally friendly building, awarded by the Indian Green Building Council (IGBC), the Indian chapter of the US Green Building Council.1/4

Inside the Renovated and Hi-Tech Bombay House

The ground floor of Bombay House has been converted into a shared space housing an in-house coffee lounge, informal breakout places, and the Tata Experience Centre (TXC). TXC, a digital museum, is aimed at giving visitors an immersive experience into the world of Tata using digital technologies for effective storytelling. In a first for Bombay House, a kennel has been created for the canine friends who have been an integral part of the building for decades. The four floors of the building house offices of major Tata organizations. The historic boardroom on the fourth floor has been restored to its original beauty with only technology being a new addition.

The new technology set up in the building has been designed to create digital workplaces with seamless integration. Each floor has digital meeting rooms with immersive technology to enable seamless collaboration. A custom-made app has been developed to bring together all the technology controls through an intuitive and simple interface. The four-story Bombay House is owned by The Associated Building Company, part of the Tata Group.

Bombay House is the only heritage building in the country to receive ‘Platinum Rating’ by the Indian Green Building Council (IGBC), under their Existing Building rating system, Bombay House has received this rating for continuously implementing measurable strategies and solutions in five categories: site & facility management, water efficiency, energy efficiency, health & comfort, and innovation.

The project was implemented with the support of occupants of the building, The Associated Building Company Limited (ABCL), a Tata group company, responsible for the building, and Eco first Services, the sustainability arm of Tata Consulting Engineers Limited, which works in the area of building retro-commissioning and facilitation.

Air Distribution Products contribute a Major Role in Indoor Air Quality of a Building

Healthcare, safety, efficiency and equitability are some certain of the concerned facts which every human must remain aware about. With the improvement of technology and science, improving quality in healthcare has become an important measure.

Air quality  indicates the estate of the air in the surrounding. Good air quality pertains to the degree which the air is clean, clear and free from pollutants such as smoke, dust among other gaseous impurities in the air. Air quality is determined by appraising a variety of pollution indicators.

Effects of bad air quality

Poor air quality is a universal problem. Polluted air is directly linked to a variety of health concerns, ranging from short-term irritation to serious diseases. Most of the pollution that’s affecting our air comes from human activities. It is a result of manufacturing, transportation and a dependence on fossil fuels like gas and coal. Exposure to pollutants like smog, sulfates, nitrates and carbon can have a powerful impact on both human health and the health of the earth.

According to the LEED & IGBC APs- Sustainable Professionals, air quality inside the home is often two to five times worse than it is outdoors. After certain activities, like painting or floor removal, the air in your house can be up to 1,000 times worse than the air outside. This is due to off-gassing of volatile organic compounds found in paint, adhesives and many everyday objects in the home.

We all need clean air 

With the improvement of technology and science, improving quality in healthcare has become significant.

On average, a person inhales about 14,000 liters of air every day, and the presence of contaminants in this air can adversely affect people’s health. People with pre-existing respiratory and heart conditions and diabetes, the young, and older people are particularly vulnerable.

Clean and good air, like clean water, is in short supply around the world. Many of us take the air we breathe for granted, but we shouldn’t.

Without clean air, we cannot live.

Air Ventilation

Another approach to lowering the concentrations of indoor air pollutants in your house is to increase the amount of outdoor air coming indoors. Ventilation and shading can help you to control indoor temperatures. Ventilation in addition helps remove or dilute indoor airborne pollutants coming from indoor sources. This reduces the level of contaminants in air and improves indoor air quality.

Monday Flashback #24 – Sabarmati Ashram, Ahmedabad

This Monday we are back with another Flashback, this time we are featuring the Sustainable Architecture of Sabarmati Ashram, Ahemdabad is a Classic Example of Modern and old Architecture with all the Sustainable Practices involved. Let us Understand about the Architecture of Ashram and the Sustainable practices involved in that.

This memorial museum is located in the ashram where the Mahatma lived from 1917 to 1930. Housing his books, letters and photographs, this modest and humanly scaled memorial uses brick piers, stone floors and tiled roofs to find a contemporary expression for the spirit of swadeshi.

The museum uses a simple but delicately detailed post and beam structure. Load bearing brick columns support concrete channels, which also support the wooden roof. The foundation is made of concrete and is raised about a foot from the ground.

The commission was the architect’s first important work in private practice. In order to reflect the simplicity of Gandhi’s life and the incremental nature of a living institution the architect used modular units 6 metres x 6 metres of reinforced cement concrete connecting spaces, both open and covered, allowing for eventual expansion.

The modular simplicity of the structure is continued in the use of basic materials: stone floors, brick walls, wooden doors and louvred windows devoid of glass, and riled roofs. The units are grouped in a consciously asymmetric manner to be analogous to the Indian village with its pathways and seem­ ingly randomly placed buildings and its meeting points; in this instance the central water court.

The initial construction con­sisted of 51 modular units. Some of the units are enclosed by walls; the exhibition spaces so created counterpointed by areas for rest where the visitor can sit … Since its inaguration by Jawaharlal Nehru in 1963 the units have been added to, extending the existing pattern.

In this work Correa demonstrates the uncompromising execution of an idea as a powerful statement of form, an approach found in many of his works such as the ECIL Office Complex and the later Kanchanjunga apartments – where single overriding con­cepts become the major organising element of the architecture.

The materials used in the construction are similar to those in the other buildings in the Ashram: tiled roofs, brick walls, stone floors and wooden doors. The only addition is the concrete channel that acts as beam and rainfall conduit, and which permits expansion for additional construction to be addded in future. No glass windows were used anywhere in the building (in deference to Gandhi’s rejection of modern industrialized products), light and ventilation being provided by operavle wooden louvers.

These elements combine to form basic modular units of 6×6 m, in a typology analogous to the villages so central to Gandhi’s thinking. They are grouped in a casual meanderiing pattern, creating a pathway along which the visitor progresses towards the centrally situated water court (refreshing in the dry heat of Ahmedabad). Some of the units are enclosed by walls; the various display-cum-study places so created being counterpointed by areas of visual rest where the visitor can meditate. This configuration generates a wide spectrum of conditions, varying all the way from closed-box to open-to-thesky, the modifications from one zone to another along the spectrum being signalled by subtle and almost imperceptible changes in light and air movement.

Because the collection will, by its very nature, be added to in time the Sangraha­laya is a living structure which can grow and modulate. Recently, more units were added, extending the pattern. This pro­cess will continue as more photographs, letters and other documents are col­ lected, each generation of young Indians making its contribution and paying its homage to the Mahatma.


Methods to reduce Energy Consumption from our homes

Energy Efficiency – the subject everyone knows about but most of us don’t know what to do about it. Everybody wants to reduce their energy consumption and pay less electricity bills but most of us don’t know how to do it.

Well, today we are going to talk about what can be done to reduce your energy consumption.

Need for Energy Efficiency

So before talking about what to do for energy efficiency, let’s talk about WHY Energy Efficiency?

Energy efficiency means delivering the same (or more) services for less energy. When we use less energy, the less energy we need to generate at power plants, which reduces greenhouse gas emissions and improves the quality of our air. Energy efficiency helps the economy, too, by saving consumers and businesses millions of dollars in energy costs. Energy efficient solutions can reduce the energy bill for many homeowners and businesses by 20 to 30 percent.

How to achieve Energy Efficiency – 

There are many different ways to reduce your household’s energy use, ranging from simple behavioral adjustments to extensive home improvements. The two major motives for conserving energy are to save on utility bills and protect the environment.

Here are some ways in which you can save the energy & electricity in your house – 

  1. Adjust your day-to-day behaviors

To reduce energy consumption in your home, you do not necessarily need to go out and purchase energy efficient products. Energy conservation can be as simple as turning off lights or appliances when you do not need them.

2. Replace your light bulbs

Traditional incandescent light bulbs consume an excessive amount of electricity and must be replaced more often than their energy efficient alternatives. Halogen incandescent bulbs, compact fluorescent lights (CFLs), and light-emitting diode bulbs (LEDs) use anywhere from 25-80% less electricity and last three to 25 times longer than traditional bulbs.

3. Purchase energy efficient appliances

On average, appliances are responsible for roughly 13% of your total household energy use. When purchasing an appliance, you should pay attention to two numbers: the initial purchase price and the annual operating cost. Although energy efficient appliances usually have higher purchase prices, their operating costs are 9-25% lower than conventional models.

When purchasing an energy efficient appliance, you should look for appliances with the ENERGY STAR label

4. Upgrade your HVAC system

An HVAC system is composed of heating, ventilation, and air conditioning equipment. Heating alone is responsible for more than 40% of home energy use.

Upgrades to the component of an HVAC system – ventilation – can improve your energy efficiency. A ventilation system is composed of a network of ducts, which distributes hot and cold air throughout your home. If these ducts are not properly sealed or insulated, the resulting energy waste can add thousands of rupees to your annual heating and cooling expenses. Proper insulation and maintenance on your ventilation system can reduce your heating and cooling expenses by up to 20%.

5. Insulate your home

Insulation plays a key role in lowering your utility bills through retaining heat during the winter and keeping heat out of your home during the summer. The level of insulation you should install depends on the area of your house. Your attic, walls, floors, basement, and crawlspace are the five main areas where you should consider adding insulation.

Conclusion – Energy conservation is important and beneficial as you can save money, save environment. Take needful measures today only so that our future can also enjoy something which we are exploiting.


How aerators can help in saving the water ?

Water Aerators | Conserve water in a smoky way

Water aeration – brings water and air in close contact in order to remove dissolved gases such as carbon dioxide and oxidizes dissolved metals such as iron, hydrogen sulfide and volatile organic chemicals (VOC’s). 

Aeration brings water and air in close contact by exposing drops or thin sheets of water to the air or by introducing small bubbles of air (the smaller the bubble the better), and letting them rise through the water. 

Faucet Aerator – 

A Faucet Aerator or Tap Aerator is often found at the tip of modern indoor water faucets. Aerators reduce the water coming through the faucets by mixing it with water. The aerator acts as a sieve, sending a separating a single flow of water into many tiny streams.

There is less space for the water to flow through, the water flow is reduced. However, the water pressure is maintained.

Check Faucet Aerator by ECO 365

Function of Faucet Aerator – 

An aerator can –

  • Prevent splashing
  • Shape the water stream coming out of the faucet spout, to produce a straight and evenly pressured stream
  • Conserve water and reduce energy costs
  • Reduce faucet noise
  • Increase perceived water pressure
  • Provides slight filtration of debris due to a small sieve plate

Pond Aerator – 

Pond aeration is key for creating and maintaining the perfect pond. 

Adding an aerator system to the pond or lake can provide many key benefits including increased fish activity and populations, clearer water conditions, reduced algae and muck, as well as preventing icing over of the pond during winter.

Pond Aeration is supplied by a pump that moves water throughout the pond and provides circulation. Aeration is improved even more when the water surface is broken by means of a waterfall or fountain.

Chemicals removed by Aeration – 

Constituents commonly affected by aeration are:

  • Volatile organic chemicals, such as benzene (found in gasoline), or trichloroethylene, dichloroethylene, and perchloroethylene (used in dry-cleaning or industrial processes) 
  • Ammonia 
  • Chlorine
  • Carbon dioxide 
  • Hydrogen sulfide 
  • Methane  
  • Iron and Manganese 

Advantages of using Aerators – 

  • Aerators are inexpensive and easy to use. 
  • They come in varying abilities to control the flow. 
  • Aerators can save you up to half of your water usage through faucets with aerators on them. 
  • When you are using aerated water, you won’t notice a difference.
  • Estimates are that aerators can save you 280 gallons a month.
  • If you use less water, you will use less gas or oil to heat it. This means you will also see a savings on your heating bill.

Conclusion – So this is one of the most cost effective and energy effective manner in which we can conserve water. Also it’s quick and easy installation make this new tech product a must buy.

Water Conservation Technique – Products that Reduce Water Use In Buildings

Water is an indispensable resource but pressures on freshwater resources across the world are growing rapidly due to population growth, increased industrial activities, urbanization, and of course changing lifestyles. India like the other countries is severely in-immune to these water pressures, in fact, it wouldn’t be wrong to the say – Water pressures in our country is being felt much more rapidly than expected.

Bengaluru for example made to the news of turning the next Cape Town, to face the threat of running out of potable water by 2020. Developing parts of Bengaluru is now facing severe water pressure and receive less water per person. In fact, most of the new and upcoming apartments depend largely on tanker water for drinking and other use.

Water pressures and the dangers lack of adequate water of appropriate quality poses for people, industry, and ecosystems, have been time and again highlighted in several reports. However, the main aim behind highlighting the issues remain same – Water conservation is the need of the hour.

Water Conservation Techniques – 10 Products That Help!

Today much innovation has gone into creating and developing products which improve water efficiency in buildings.  With adoption of water conservation techniques being the strain of this blog, here are 10 innovative products which can help reduce water use in buildings.

1. Greywater Recycling Systems

The water used in most building structures is thought of in terms of clear clean water coming in, and sewage or black water going out. However, greywater is something that is in between that. In the domestic setting, greywater systems collect water from sources like baths, hand basins, and showers. This collected water is reused for washing machines, toilet flushing, and other external usages. The main idea behind greywater recovery is simply getting the most out of the water through its efficient reuse.

2. Rainwater Harvesting

Rainwater harvesting systems can vary from the basic small ones, like the attachment of a water butt to a rainwater down-pipe, to the complexly designed large ones like those which collect rainwater from large areas and serve momentous numbers of properties. When it comes to domestic purposes, these systems are relevant to both commercial and domestic properties. When collected, rainwater can be used for garden irrigation, toilet flushing, and even in washing machines.

3. Efficient Irrigation Technology

Beautiful lawns and gardens demand a significant amount of water for its maintenance. In addition to indoor fixtures, efficient outdoor irrigation technologies like smart irrigation controllers can help to save a lot of water. These controllers can effectively track factors like precipitation or temperature and avoid over-watering the properties landscaping or plantations. In addition to smart irrigation controllers, one can save even more by trading out spray sprinklers for drip irrigation. These sprinkles can deliver water to your plants directly as these can be buried under the lawn.

4. Water Meters

Water metering is a common term used by people when the discussion is around water conservation techniques. Water metering in simple terms is the process of measuring the water use in each residential apartment. Water meters are installed in each home of an apartment and these meters record the amount of water being used in a home for billing purpose or tracking consumption.

5. Pressure Reducing Valves

High water pressures waste a lot of water. Installing water pressure reducing valves turn out to be one great solution. These valves are can be used in residential, commercial, and institutional applications to lessen the incoming water pressure to a lower predetermined level. In this way, it protects the downstream plumbing system components as well as reduces the water consumption.

6. Insulated Pipes

Insulating all piping and storage tanks are important for any domestic hot water system today. Sadly, in most of the buildings, hot water return pipes are uninsulated or not insulated correctly. As a result, when hot water is needed, the user needs to wait at faucets or showers for the hot water to flow. This can result in significant wastage of water. When pipes are properly insulated it ensures hot water is immediately available and when the tap is closed it supplied back to the plant, consequently reducing the energy demand of the heating unit. With insulated pipes, the user is less likely to waste by waiting for it with the taps open.

7. Efficient Taps

Water-efficient taps work in two ways, they can either reduce the water flow rate through the tap or they can support the user to avoid wastage of water by automatically turning it off. These days sensor taps can be seen in almost every shopping mall or airports, these automatically sense the user’s activity based on which is supplies or turns off the water flow using infrared sensors.

8. Water-Saving Showers

Personal bathing accounts for a lot of water use within homes, hotels and other residential settings. Did you know, an average bath uses around 80 liters of water whereas a 5-minute shower at 10 liters per minute will use only 50 liters of water? Water-saving showerheads control the water flow rate and spray pattern of your shower. These are available in a good range of different shapes and sizes and their design can directly affect water consumption during bath.

9. Efficient Toilets

In 1995, The National Energy Policy Act mandated that all new toilets had to be low flow toilets using no more than 1.6 gallons per flush which were less than half the water used by toilets in the 1980s. Initial results were dissatisfactory but then came the pressure-assisted flushing. The principle of water-efficient toilet design and operation was the shift from removing waste by using flush water volume to increasing flush water velocity. With the limited supply and continuous waste of water resource, it is crucial that we wake up and use it wisely so that we can protect and preserve our environment, minimize the effects of drought and save energy and finally the water bills. Upgrading to low flow toilets can play a crucial role in reducing water footprint.

Water is a necessity; it is the fuel for life on earth. But, even when its supply may seem abundant, it’s not an infinite resource – Remember fresh potable water is scarce and that’s key to our very survival.

If we don’t acknowledge this fact and take it into consideration in designing and constructing; this vital supply of water can be in danger. We, as engineers, developers, and owners, play a crucial role in looking beyond our building budgets and codes to achieve higher levels of water efficiency. No doubt, new and innovative technologies which consume less water have become increasingly important. It’s our realization and common sense that can save our planet and ensure our future generations can enjoy the benefits of abundant freshwater.

Start using these water conservation techniques today! It’s over to the decision that we make now!

Govt. Involves to Make Sustainable Cooling Hubs for Communities

Experts from the University of Birmingham are to work with groups in India to explore how sustainable cooling can help Indian farming communities.

Launching the project on World Refrigeration Day (June 26) with a workshop in New Delhi, sustainable cooling experts will look at ways to reduce food waste, increase farmers’ income and meet rural communities’ cooling needs in an affordable and sustainable way. It intends to begin by developing ways of integrating food cold chains with other cold-dependent services such as community health facilities, social facilities such as creches and even emergency services.

Researchers from the Birmingham Energy Institute, Heriot-Watt University in Edinburgh, and the Centre for Environment Education (CEE) in India are supported by the Shakti Foundation and will join efforts with India’s National Centre for Cold-chain Development (NCCD) in this new project.

Representatives from Government, farming communities, NCCD and agri-business will take part in the one-day event to kick off the programme to deliberate on the concept of Community Cooling Hubs. A second event is being held in Pune to engage with farmer and civil society organisations.

The participants believe that creating Cooling Hubs as business units could meet the livelihood, nutrition, employment, and education requirements of the communities. Using appropriate technology and business models, it says, will help to remove barriers that stop subsistence farmers from using temperature-controlled logistics. These Hubs can also be deployed to provide the local community access to other refrigeration dependant services.

With up to 40% of food in India lost post-harvest because of lack of cold chain, the University of Birmingham is proposing a radical approach to cooling provision, where cold chains meet the wider community’s cooling needs in a clean, affordable and sustainable way. 

“Cooling hubs could support farmers, whilst ensuring that communities have continuing access to life-saving medicines and properly cooled health facilities and community services,” said the University’s professor Toby Peters.

This project will explore how temperature-controlled food pack-houses could innovate to hybridise and employ technologies to meet other community-based cold needs.

The cooling system could be used to cool a community hall to serve as a crèche for infants or elderly; perhaps providing a schoolroom for classes on the hottest days of the year. Vaccines and medicines could be safely stored at these hubs for local health care services.

The Hubs could host secondary agricultural activities that utilise local resources in terms of labour and farm output, such as processing milk into cheese or yoghurt, making jams and pickles, and Hindu holistic medicines. They would be employment hubs for the local community.

“Community cooling hubs take forward refrigeration from the immediate realm of cooling machines, into the dimension of collaborative technologies and models to drive a weightier wellbeing,” said NCCD CEO Professor Pawanexh Kohli.

The project follows the University of Birmingham’s partnership earlier in the year with the World Bank Group and UK Department of Business Energy & Industrial Strategy (BEIS) to host a global Clean Cooling Congress around sustainable, accessible cooling for all who need it – without over-heating the planet.

Experts at Birmingham plan to work with the NCCD and others, over a period of 12 months with farming communities in the state of Maharashtra. They will be supported by colleagues from Heriot-Watt University, the University of Edinburgh and ImechE.

light sensors

Lighting Sensors | The ultimate way for Energy Saving

Whenever we talk about energy saving we always talk about changing our daily habits, and go for energy efficient appliances. But in this modern era of technology where we have more than just bulbs and lights, then why only stick to the old traditional ways. It’s time that we should expand our vision and look for some other alternative which can give us more efficient output.

Lighting Sensors

The ultimate solution for using light only when needed is – Lighting sensors. Lighting sensors help you everyday by detecting and reacting to different levels of light in appliances, switches and machines. 

The light sensor is a passive device that convert this “light energy” whether visible or in the infra-red parts of the spectrum into an electrical signal output. Light sensors are more commonly known as “Photoelectric Devices” or “Photo Sensors” because the convert light energy (photons) into electricity (electrons).

Motion Sensitive Light Switches

One such product which has caught our attention and gained a lot of popularity over the past few years is motion sensor light switches. Motion sensor light switches turns on when they sense someone in the room and are switched off after a certain amount of inactivity. Motion sensors reduce electricity consumption by eliminating the possibility that the lights will accidentally be left on.

You see them more and more in corporate and public spaces, because they are convenient for employees and shut off after continued inactivity, significantly reducing energy expenses.

In order to detect the presence of a human being inside a room properly, the motion sensor can take advantage of several types of technologies – 

Pyroelectric Sensor – It measures the infrared radiation, and since everything emits a certain level of IR radiation, it is quite easy to detect major fluctuations emitted when a person passes by. The disadvantage is that the sensor will detect only significant movements and only in direct line of sight.

Ultrasonic Technology Sensor – This sensor uses the ultrasonic technology in order to detect smaller changes into the environment so the light doesn’t turn off when you’re reading a book or typing on the computer keyboard. To accomplish it, the sensor sends a small pulse into the room, which returns and allows the device to detect any changes. The disadvantage is that it can be prone to false detection and it draws more power.

Motion sensor light switches reduces energy consumption by 35-45 percent, and can go up to as high as 75 percent. 

Conclusion – 

Changing the light switches is a minor project, but one that can be incredibly convenient – not having to worry about turning off the lights when you are gone, especially in places that are frequently used, eliminates a common habit that many wish they could get a hold of.

Understanding the Requirement of Cool roof to keep the Temperature of the Building Moderate & Efficient

How building envelope acts as thermal insulation!

The “building envelope” of the building includes the outside walls, windows, doors, roof, etc. of the home. It is the skin of your house and helps protect everything inside. It offers a physical separation between the environments outside from the one inside the building.

The kind of building envelope you choose will determine how comfortable your home remains at different times of the day, night and during the year. A well-designed building envelope helps in keeping the house as warm, cool, or lit by natural conditions for longer durations, to avoid the use of heaters, air-conditioners or indoor lighting as often.

The thermal envelope of the building is considered as the heat-controlling layer, which is largely the ceiling and the façade of the building. The cool roof coatings offer a wide range of benefits including the lengthening of the roof life, ensuring waterproofing and providing reflectivity.

The heat reflectivity characteristic of the coatings aids in offering UV protection and cooler inside environments, lesser use of air conditioning ultimately lowering the energy utility costs. Moreover, using a heat reflective coating or coating tiles enables cooling at places that cannot be air-conditioned including garages, patios and others.

Which factors enable improved energy efficiency in a building?

Variety of options are considered for enabling improved energy efficiency in building design with improved designs of rooftops. Ceilings of the building can be coated with highly reflective paints, tiled, made as green with plantations, overlapped with panels of materials such as wood, fiberglass, polymer and metals.

Several kinds of research have shown that the external colors of a building have a significant impact on the cooling load of the building. A white reflective cool coat can potentially reduce up to 60% of the heat coming in from the ceiling offering it ultimate protection from thermal heat. However, the results vary in different situations. With various experiments, researchers have found savings to vary from 20% to 60%. Typical rooftop reflective coating paints are made of acrylics, Hypalon, neoprene, silicone, and urethane and hybrid materials.

Cool roof coatings not only prevent extra heat from entering a house but also have many other benefits too including the increase in the lifespan of the roof by 15 years or more. Dense cities with a lot of dwellings in a small area have tendencies of getting heat up significantly. If the houses are acquired with reflective rooftops, then the amount of heat waves can be reduced. In general, it can add to greening by reducing waste and saving electricity.

EXCEL Coat is one such type of sustainable rooftop solution which offers a wide range of products including Coal Coat, NanoSeal, StayCool, CoolTile and InsulX which helps in maintaining the temperature of the interiors of the building. Excel Cool Coat is a heat reflective roof paint to reduce the summer heat on the roofs. It is a reflective paint for exterior walls and first of its kind cool roof technology in India. It is a water-based, high solid, PUD hybrid roof coating that contains both reflection and Nano insulation pigments for best in class heat protection. Along with it, the adhesion enhancer & Nano UV protectors prevent the coating from UV degradation delivering excellent weather ability and longer service life.

This heat reflective cool roof coating is powered with micro-fibers for excellent waterproofing & crack resistance.  It comes with reflection, insulation, and waterproofing. It is the time proven and tested the paint to reduce heat on the roof.

Some of the important points for consideration on excel coatings are stated as under:

1. Normally reflective coating contains only reflective pigments, which work on the basis of reflection. In the current scenario, carbon & fine dust settling is very high, which when settles over the coated surface spoils the reflectivity of the heat reflective roof coating. Thus the coating fails & desired performance is not achieved. To prevent this failure, EXCEL CoolCoat contains high-performance Nano-insulating material to efficiently protect heat from entering inside.

2. Contains high-end Nano UV protectors which protect the coating from aging & degrading within a few years.

3. Contains addition enhancers which provide excellent addition property across a variety of surfaces.

4. Contains reinforced microfibers for excellent water proofing and cracks


Waterless Urinals Technology by Zerodor !

There is a situation like a tug of war happening in the minds of people regarding the catastrophic environmental crisis because of reduction of water levels as well as increased amounts of GHG emissions in the atmosphere and the traditional, conventional ways of using the resources which is a habit formed over the years.

What is the problem faced today?

Water scarcity coupled with poor sanitation and hygiene practices is a grave concern faced by the people all around the world. Millions of people do not have adequate water for drinking purpose and with a solution to conserve fresh water, 14 or more families can meet their daily requirement for water. According to the data by environmental agencies the average amount of water which is wasted in every flush is calculated to be about 4 liters which unnecessarily goes to drain. Flushes on an average are used 5 times a day by a person which makes it 20 liters of fresh water waste by a person in a day

Is there a way out?

This water if restricted from getting wasted can be used for other purposes in organizations or households. Most of the buildings constructed use the solution of recycling as an alternative where grey water is used to flush toilets. There are solutions coming up on the principle of reducing where the product is equipped in a water system.

The use of grey water for flushing reduces the consumption of water by 25-35% and treatment and storage plant is usually installed at 50,000 to 1 lac INR. But one of the drawbacks registered by the users is the odour of water and initial installation process cost. 

There is another effective technique which cuts on water consumption and offers an odour free solution which uses bacterial cultures to clean away the waste from PeePee. The use of zerodor product advises the people on some bustling myths where the consumption of water cleans the urine waste flushing it away which on the contrary complicates it as ammonia of urine mixes with water and produces a bad odour.

Energy-Conscious | Use of Eco-Friendly Glasses in a Building

It’s nothing new to say that, we are on the verge of wiping out our most the resources. And the most scaring one is the Energy. Inappropriate use of resources has led us to a situation where we are not only short of resources but we have created harm to the environment is a massive way. Global warming, ozone layer depletion, shortage of water electricity and much more are merely a result of human’s need and greed.

One of the industry where the most efficient use of resources can be done but due to the lack of awareness, wide wastage of resources are done – ‘Construction.’ While constructing a home or a building most the people are unaware of the fact which materials to use which are not budget-friendly but also eco-friendly and most importantly will be durable for longer period of time.

Today we are gonna talk about one such material which will not only save energy but have several other benefits too.

Eco-friendly glasses

It would be not wrong to say that almost every building utilizes glass in one or another way, still it is one of the most overlooked building construction material. There are many who remain unaware that using right type of glass can make a major difference in the energy consumption of home.

Not only one use an ‘eco-friendly’ glass while constructing their house but it is also feasible to change the glass of an existing house/apartment from regular to one that is more ‘Eco-friendly.’

With the raising awareness about use of sustainable material increasing day by day, property developers and real estate companies are also doing their bit in improving the environment for a better future. This has led to the boost of green buildings.

One of the most vital materials within the construction of a green building is glass whose specialized energy efficient and eco-friendly varieties like solar control and tinted glass are used.

Green Buildings

The development of green buildings is a step towards that direction. Green buildings are buildings which use less water, optimize energy efficiency, conserve natural resources, generate less waste and provide healthier spaces for occupants, as compared to a conventional building.

They are also beneficial for the environment as most buildings use recycled and environmental friendly building materials and provide effective building management systems.

Econaur is one such platform which promotes the use of eco-friendly products and sustainable development. Econaur’s main focus is to promote the construction of more and more green buildings in the country. Also to aware people of the advantages and clear the myths about the green buildings.

Use of Glass in Architecture of Green Buildings

To achieve all of this, developers use glass as a major component during the construction. Glass is known to be an excellent green material. Glass, as a transparent material, allows sunlight into the building reducing the need for artificial lighting – which contributes to around 25 per cent of energy consumed in buildings today.

Types of glasses like solar control glasses and low-e glass can reflect heat or UV rays to maintain optimal temperature inside the building. Glass in buildings also allows daylight to make the interiors airier and more open.

From design, appearance, thermal performance and comfort, to simple aesthetics, selecting the right glass is inevitably important for constructing a green building.

Glasses such as AIS Ecosense, a low-E high performance energy efficient glass helps a green building achieve great balance between all the parameters, and blocks a high amount of solar radiation by reflecting away the infrared part of sunlight.

This helps building remain invariably cool in summers and cuts down on the energy bills and air conditioning usage. And in the winters, they ensure solar gain. So no matter what the season is, people can stay comfortable inside all the times.

Glass and Energy Saving

When used properly, glasses can reduce the total energy consumption by anywhere between 8-10 percent. Hence, the accrued benefits of using glasses keep growing over the years.

Furthermore, it is not just the recurring savings but also the reduction in capex because of the lower energy loads required for conditioning the building that further augments the versatile nature of these glasses.

Typically, the heat gained or lost through glazing in a normal building is anywhere between 40-50 percent and using the right type of glass can bring down the energy consumption by 30-40 percent. The incremental cost for high performance glazing can be recovered in a time span of 3-4 years.

Are these eco-friendly glasses expensive?

Once considered an expensive commodity, glass today is cost efficient. It is true that, to begin with, achieving Green Buildings meant shelling out something extra. This was the majorly due to limited supply of access to technology and products that help achieve such efficiency.

However, today we have product manufacturers, cutting across product lines, which have been able to develop green friendly products in India thereby making it affordable and price-competitive.

The products efficiency and pricing have come to a level where it is practically possible to recover the incremental cost within the first few months of completion and occupancy.

Impact on Environment

The biggest advantage that makes glass a major component in green buildings is the fact that it is recyclable and also does not have a huge impact on the environment itself. Glass can play a role in accomplishing greater indoor environmental quality and when used carefully, can also improve energy efficiency.

Along with tangible benefits, glass can also provide enhanced air quality, excellent daylighting and general health & well-being of the occupants. Through a global point of view, conservation of scarce national resources is also a huge advantage while its widespread acceptance and enhanced marketability for the project makes it a viable option for the industry too.


Little things only makes the big differences. And as little as making changes to what kind of glass you are using in your home/building can make a huge difference for both you and the environment. I think it is the perfect time now that we should start thinking for nature and also for our future generations. Making changes today only can ensure a safer future tomorrow.

Failure to uphold some level of cleanliness can cause serious health problems for both for you and your loved ones.

But in today’s kind of lifestyle where everyone is in a hush and rush, most of us don’t care much what we are eating or what products we are using. And as a result, we have some serious health or skin related issues. We wonder then, we have been taking care of our health but how did this happen. And we cannot find the real issue behind the problem we face.

Harms of Using Chemical Cleaning Solutions
Have you ever wondered how did we really go on to buy Chemical Cleaning Solutions? Every day we keep hearing that chemical products are harmful, we should opt out of using chemical products, but still, then we go on using them.

The real reason for such a problem is the lack of research and the easy availability of chemical products. We go to any shopping mall to take all our monthly groceries and in a hurry, we choose such cleaning products or hygiene products which in future harms us only.

I will tell you now, what possible health hazard these chemical products pose. Some of these chemical products can cause acute or immediate problems like respiratory irritation, watery eyes, skin problems, chemical burns and not only this some of them can give you chronic diseases like cancer.

And to your surprise, the most dangerous chemical products are drain cleaners, acidic toilet bowl cleaners, and oven cleaners.

What should be done to stay Healthy?

There is Rapid rise in Green Airports in India Now !

With the Growing Infrastructure and raising awareness about green buildings, there is a rise in Green Airports in the recent years.

Recently, PM Modi lays foundation stone for Trichy airport integrated terminal building

Prime Minister Narendra Modi on Sunday laid the foundation stone for the new integrated passenger terminal building at the international airport in Trichy , through video-conferencing from Tirupur . The new building will have incorporating local themes. The first phase of the project also includes the construction of aerobridges, car parking, and new residential quarters of AAI and CISF staff.

The new airport terminal project manager P Srikrishna said along with new integrated terminal building, construction of new technical block cum control tower would also be taken up at an estimation of Rs 75 crore. All the work would come under the first phase of this project”, he said.

The terminal building would be constructed as per the standards of ‘GRIHA’ (Green Rating for Integrated Habitat Assessment) four star rated sustainable design which maximises the use of natural light within the building and incorporates renewable energy measures, such as rainwater harvesting, ground source heat pumps and photovoltaic panels.

No objection certificate for height clearance has been already obtained for 42.5 meter, as this building would be the highest one at the airport. As the existing apron is accommodating only seven planes, two additional bays will be constructed at a cost of Rs 10 crore to meet the demand. The new terminal building would come up at an estimated cost of Rs 951 crore near the existing terminal building. The project is expected to be completed on October 18, 2021.


The Airport Authority of India (AAI) has already sanctioned Rs 951 crore for the construction of the 61,634-square-meter integrated terminal building, along with a new apron and Air Traffic Control (ATC) tower. Out of the total outlay of Rs 951 crore, Rs 564 crore has been allotted to construct an integrated terminal building. The new two-level modular integrated passenger terminal building would be fully air-conditioned to handle 3.63 million passengers a year on full capacity and 2,900 passenger during peak hours with provision for expansion.


To make the terminal building eco-friendly, it follows the concept of green building with innovative technology. Making a sustainable building is always profitable in the long run to both the environment and in this case to the nation. Also, this is a great way to promote and declare that more green buildings should be constructed in our country. So, overall it is a commendable step taken and also its foundation stone is laid by one of the most powerful leader of our country PM Narendra Modi, so as a citizen it is the proud moment for all of us. The new airport will follow the Low energy Consumption & water consumption equipment all over its Premises.



perlcon block bond

Perlcon’s BlockBond – An Revolutionary Product that replaces the use of Sand in Construction

Blockbond – The Newest Aid In Construction

Construction – a term with which everyone is aware of. Thousands of new buildings are getting constructed every day. But with everything around us moving so fast, don’t you feel our construction ways and materials used are still quite old for the new world.

For the construction of normal buildings, the basic materials which are required are cement, dry sand, concrete, bricks and blocks and much more.

But what if there is a way which doesn’t require sand for construction.

Blockbond –

Nowadays, AAC/CLC blocks are used for construction as they are lightweight, evenly finished provides better insulation. Also, they are much stronger & use less water than the CC/Blocks which were previously used.

However, such great properties of these new blocks are nullified when they are mixed with the old method of preparing mortar i.e. mixing dry sand and cement. Due to their mismatching properties, thicker joints are formed and huge possibility of cracks in walls also arises.

What if there is a way to maximize the use of AAC/CLC blocks.

Use Perlcon Blockbond, light weight mortar, which is not only lightweight but also provides high strength and low probability of cracks.

It is a sand free plaster which is a premixed material supplied in bags. It can be applied directly by just mixing it with water.

Benefits of using Blockbond –

  • As it is sand free, it reduces the dead load on the building.
  • It is anti-fungus
  • Saves time and cost
  • Lasts long
  • It is self-curing reduces water consumption by minimizing ill-effects of hard water.
  • Crack free
  • Dust free and clean
  • Lightweight
  • Efflorescence free
  • Smart construction which reduces manpower

As per the survey “constructing a 12-floor building with this material would save 1,100 metric tonnes of sand, 6,000 kilolitres of water, 7,500 kilowatt of electricity and 15,000 kilowatt by way of energy conservation due to insulation in plasters, besides huge savings in time and labour costs”.

Technical Specifications –

Dry density: 1150 kg/cum (+/- 5 %)

Initial setting time: 90 – 120 mins

Final setting time: 200 – 260 mins

Pot life: 3 hrs

Coating thickness: 10 – 18 mm

Coverage*: 125 kg/100 sq.ft. (10 mm thick plaster)

Shelf life**: 6 months

Ideal for use at 27oC – 30oC

How to apply –

Fill a clean pot with potable water measuring 18% (+/- 5%) the weight of Sand free Plaster (1 kg Sand free Plaster: 0.18 litres water).

Now pour Sand free Plaster into the pot. Mix and knead slowly to form a homogeneous paste. Let the mixture stand for 10 minutes. Mix the green mortar again without adding more water.

Evenly apply a coat of Sand free Plaster with a mason’s trowel or with the aluminium level patty.

Apply aluminium level patty from bottom to top direction followed by a left to right & right to left direction without leaving stroke marks to level the plaster.

After initial setting applies aluminium scrapping patty to achieve the true level and create a rough texture for a subsequent coat.

Over smaller area and in corners, apply a grilled float to open out plaster surface. Remove loose particles.

After 45 min apply steel/float/muster, if necessary with a little sprinkling of water to achieve a perfectly levelled plaster surface.

Smooth, levelled, Sand free Plaster wall is now ready. No curing is required.

Conclusion –

So undoubtedly, this is the new way of constructing your new home which is not only cost-efficient but also environment-friendly. Hence, it is a high recommendation to go for it and enjoy a better home.

Monday Flashback 22 – Panch Mahal, fatehpur Sikri, Uttar Pradesh

The Panch Mahal meaning `wind catcher tower’ was commissioned by Mughal Emperor Akbar This structure stands close to the Zenana quarters (Harem) which supports the supposition that it was used for entertainment and relaxation. This is one of the most important buildings in Fatehpur Sikri. This is an extraordinary structure employing the design elements of a Buddhist Temple; entirely columnar, consisting of four stories of decreasing size arranged asymmetrically on the ground floor, which contains 84 columns. These columns, that originally had jaali (screens) between them, support the whole structure. Once these screens provided purdah (cover) to queens and princess on the top terraces enjoying the cool breeze and watching splendid views of Sikri fortifications and the town nestling at the foot of the ridge.

The pavilion gives a majestic view of the fort that lies on its left. The pool in front of the Panch Mahal is called the Anoop Talab. It would have been filled with water, save for the bridge, and would have been the setting for musical concerts and other entertainment. The ground floor has 84 columns, the first story has 56 columns and the second and third stories have 20 and 12 columns respectively. The topmost story has 4 columns supporting a chhattri. There are 176 columns in all and each is elegantly carved pillars with unique designs.


Fatehpur Sikri, known for its architecture and planning, is situated in Northern India close Agra, was worked by Akbar, the third Mughal ruler, in 1571 , as his new capital. The significant piece of the complex was manufactured/built in a limited capacity to focus four to ten years, utilizing neighborhood building aptitudes and materials.

Since the territory is near the western desert area, the atmosphere is hot-dry with generally little precipitation.


Planning and  Architecture Features

The Fatehpur Sikri complex stands on an edge and the city is encased by an embattlement on three sides and on the fourth by an immense counterfeit lake which was the primary wellspring of water supply to the city.

The edge is to some degree in the focal point of this walled territory and keeps running from South-West to North-East. All the significant structures of the complex are situated over this edge , using a similarly level territory.

fatehpur sikri    fatehpur sikri

At the outskirts, where the slants are troublesome, bring down structures are worked as props to empower simple development to finish everything. The lower structures are for the most part benefit offices congenial from the lower streets and interconnected with upper levels by steps.

A detailed water supply framework existed, enacting the direct channels and tanks at the upper patio level. The seven passage doors punctured in the city divider prompt real settlements in the areas of which the Agra entryway is the most vital (since Akbar had effectively fabricated his fortress there).


This street lies indistinguishable way from the edge and steadily ascends to give access to the royal residence complex to finish everything. The introduction of the mosque and the royal residence complex is toward Mecca while the other city structures watch the land shape as a noteworthy determinant.

At one time, the town was spread on all sides of the edge and the castle region had a fantastic perspective of the region around. Minor level changes exist between patios which are consulted by steps and are keenly abused for gravitational stream of water.

Composite climate occurs in most of the areas ruled by Mughals in North India which is characterized by dominated hot and dry conditions two third of the year and, a somewhat cold and a warm
humid season occur in the remaining one third of the year. Being sufficiently far from the equator, this region experiences clear seasonal changes in solar radiations and wind directions. The remarkable mean diurnal changes may be observed from 11-12° C in hot dry and cool dry seasons while this range narrows up to 3-6° C in warm humid season. Relative  humidity reaches up to 95% during the wet period. There is little or no rain during dry season. Hot and dusty winds blow during dry season. However monsoon winds are strong and steady (Koenisberger, 2001). Dominated hot and dry season remained a problematic situation in this region throughout the centuries. Even Babur, the first Mughal ruler in India complained about the dusty winds and climate of the region in his memoir ’Tuzik-i-Babri’ (Grover, 2002).

Microclimate Control

The gardens of paradise mentioned in the Holy Quran have been the source of inspiration throughout the Islamic world (Kausar, 2005). Mughals also used this tool not only as a  symbol but to improve the quality of the immediate surrounding environment of their buildings. The environment outside the building is important to control the inside temperature
of the building. The external air is treated by improving microclimate of the region which  consequently enhances the quality of air inside the building. Vegetation was added to improve
the quality of outer spaces and to enhance cooling by evapo-transpiration. The process of evapo-transpiration adds water vapors to the air and brings down the air temperature. The  water bodies (still and moving) were added to the palaces to improve the humidity in hot and dry regions Fountains are the better way to improve the quality of air as it  sprinkles the water drops into the air and make the process of evaporation faster. Mughals also used fountain in their buildings. These water channels and fountains are found frequently  inside the buildings. Nahar-i-Bahisht (canal of paradise) is an example of water channel which passes through internal spaces of the building to modify internal environment. Most of the Mughal buildings are surrounded by a landscaped area to modify the microclimate of the region.


sandfree challange

Be the Part of Sand Free Campaign by Econaur !

Modern forms of human existence, associated with rapid economic development, have contributed to an over-exploitation of renewable natural resources such as land and forests, and the exhaustion of non-renewable resources such as minerals and fossil fuels.

We have impacted the natural resources to a great extent for our own greed. To prevent the coming generation from the depletion of the resources and to give them a better environment we need to adapt the “Sustainable Measures” in construction.

The primary in this is the use of sand. We need to stop sand mining and adopt the measures that are “Sand free” as only this can provide us a sustainable Life. From forcing the river to change its course, to affecting the groundwater tables and adversely impacting the habitat of micro-organisms, the ramifications of illegal sand mining are many.

Sand is important for ground water recharge, on a riverbed it acts as a link between the flowing river and the water table and is part of the aquifer,” said Manoj Misra of the NGO Yamuna Jiye Abhiyan. “We have seen the impact of tampering with the rivers and their resources in the recent Uttarakhand floods. When sand and boulders are removed in an unimpeded way using heavy machines, the erosion capacity of the river increases. Sand and boulders prevent the river from changing the course and act as a buffer for the riverbed.”

As unplanned removal of sand has severe impacts on our bio-diversity: “There are a lot of micro-organisms that are not visible and widely known, but are critical to soil structure and fertility. When we dredge sand, we literally take away their habitat,”

To stop this take the sand free challenge and pledge to stop the sand mining and adopting the sustainable measures for construction and saving the environment and believe in green.




The following are the categories to submit your projects:

To be a part of this your project should be unique and is promoting the “sandfree” idea. There can be both existing and new projects that depicts and promote the Sand free Environment.

national water awards

National Water Awards – Encouraging Stakeholders in Water Sector

Ministry of Water Resources Introduced National Water Awards this year.

Water is one of the vital components of life. The rapid pace of irrigation growth, urbanization & industrialization has put enormous stress on water resources. The cumulative impact of increase in use of this precious natural resource has led to water scarcity in many regions of the country. Nevertheless, the climate change has also resulted in change in hydrologic cycle in the country. Hence, it is necessary that this scarce resource is protected by effective and efficient management on sound scientific methodology for its sustainable development.

The Ground Water Augmentation Awards and National Water Award were launched in the year 2007 with an objective to encourage all stakeholder including the Non-Governmental Organizations (NGOs), Gram Panchayats, Urban Local Bodies, Water User Associations, Institutions, Corporate Sector, Individuals etc. for adopting innovative practices of ground water augmentation by rainwater harvesting and artificial recharge, promoting water use efficiency, recycling & re-use of water and creating awareness through people’s participation in the targeted areas resulting into the sustainability of ground water resources development, adequate capacity building amongst the stakeholders etc.

Considering the fact that surface water & Ground water are integral part of the water cycle, it is felt necessary to institute unified National Water Awards with the objectives of encouraging the stakeholders to adopt holistic approach towards water resources management in the country.

Solar Energy – Important & Main Alternative Source of Energy

Solar Energy, as named the energy that we get from the Sun. Nuclear-powered fusion occurring in the sun releases enormous amount of energy in the form of heat and light. Several techniques are available for collecting, adapting and using solar energy.


Some of various devices which can be used easily to generate solar energy:

  1. Solar cells or Photovoltaic cells or PV cells: Solar cells consist of a p-type semiconductor (Silicon doped with Boron) and n-type semiconductor (Silicon doped with Phosphorus) in close contact with each other. When solar rays drop on the top p-type semiconductor, the electrons from the valence band move to the conduction band and cross the p-type junction into the n-type semiconductor. A latent difference is created causing an electric current to drift. These cells are widely used in calculators, electronic watches, street lights, water pumps, radio and television etc.
  2. Solar battery: When several solar cells are connected in series, it forms a solar battery. These solar batteries produce enough electricity to run water pumps, street lights, etc. They are generally used in remote areas where electricity supply is a problem.
  3. Solar heat collectors: Solar heat collectors consist of natural materials like stones, bricks, or materials like glass, which absorb heat during the day time and release it slowly in the night. It is generally used in cold places where houses are kept in hot condition using solar heat collectors.
  4. Solar water Heaters:It consists of an insulated box, in which is painted black on the inside. It is provided with a glass lid to collect and store solar heat. The box installed with a copper coil painted in black through which cold water flows in, gets heated in the copper coil and flows into a storage tank. Finally, water from storage tanks is supplied.
  5. Solar energy is currently used to power satellites, watches, calculators, etc.
  6. A few applications of solar energy are: (i) solar water heater

(ii) Solar cooker

(iii) Solar dryer and

(v) Solar refrigerator.

What Are Active and Passive Solar Systems?

Modern solar energy systems harness the heat produced from the sun to power residential/industrial heating and cooling systems through the use of PV or photovoltaic panels. These are also called solar cells; such devices collect and convert solar energy into electrical energy. But how this energy is captured and distributed defines the real difference between the Active and Passive Solar Systems.

1. Active Solar Energy Systems

These systems use external sources of energy to power blowers, pumps and other types of equipment to capture, store, and convert solar energy. After solar energy is captured, it is stored for later used. Dependent on the intricacy of the design, these systems can heat/cool a home or even provide power to an entire building/neighbourhood. Typically, small systems are used to supply electricity for heating/cooling systems in homes and other buildings, and hi-tech large systems can supply power for entire communities.

Pros Cons
No need to worry about deriving power from sources other than the sun, this is because it utilizes the power of your external devices. It doesn’t release carbon dioxide into the atmosphere.Heating of the PV panels helps keep them clean, even in bad weather conditions.No wind noise is generated from the solar panels. Demands expensive external equipment.High maintenance cost for the equipment.The fluids which most efficiently store heat can pollute the air by releasing toxic chemicals into the air.

The features of this system include:

  • Solar collectors are made up of flat-plate PV panels, that are normally stationary and mounted. In hi-tech designs, these panels are commonly connected with each other to form modules. These solar collectors are more complex than passive systems in both design and mechanism.
  • The solar collectors make use of liquid or air as conductors which store and convert energy. The ones which use liquid are called hydronic collectors, and the ones which contain air are known as air collectors.
  • Liquid conductors are more popular than the ones which are air-based, this is because a liquid is normally more efficient at conducting heat.

The advanced design of these collectors makes an active solar system most cost-effective in terms of dipping reliance on traditional energy sources.

2. Passive Solar Energy Systems


A passive solar system does not rely on external devices for operation. Simply put it doesn’t involve any mechanical devices or the use of conventional energy sources beyond what’s needed to regulate its control. Greenhouses, solariums, and sunrooms are classic examples of basic passive solar structures. Typically, the sun’s rays pass through the glass windows, which absorbs and retains the heat. The design and success of such systems depend totally on its orientation and the thermal mass of the structure’s exterior walls.

Investing in a passive solar system is a great idea when you are looking to power a small residence or office building.

Pros Cons
No external equipment needed, hence cheaper than active systems.It can bring down your energy expenditures by nearly 14 percent. A better option for health – because it doesn’t rely on radiators or furnaces which cause allergies or dry out your mucous membranes. Its effectiveness depends on the weather.Not suitable for locations having warmer climates, as it can potentially overheat your buildings. Demands a cautious choice in windows for extreme success.

The features of this system include:

  • Typically, passive collectors rely on south-facing windows to capture solar energy.
  • The design of the solar collectors in passive solar energy systems is based on the law of thermodynamics, that posits that heat transfers from warm to cool surfaces.
  • The easiest method of transferring the heat from passive solar collectors is through convection.

Green facade – Much needed Requirement for a Building for Energy Saving

What is a Green Facade

To “green” building envelopes is currently one of the most promising ways to provide energy savings in buildings and to contribute to the urban heat island effect mitigation. The shadow effect supplied by plants is the most significant parameter for this purpose. One way to characterize the potential shadow effect of greenery is to calculate the facade foliar density by means of the leaf area index (LAI). As LAI is commonly used in horizontal crops, their use in vertical greenery systems (VGS) has generated dispersion and uncertainty in previous studies both in terms of methodologies and results obtained. In addition, a lack of data relating to the influence of the facade orientation in the final contribution of vertical greenery to the energy savings has been observed in previous studies.

This study aims at establishing a common and easy way to measure LAI and to lick it to the energy savings provided by VGS. Moreover, the energy savings achieved as well as the influence of facade orientation on the final thermal behavior of two different VGS, a double-skin green facade and a green wall, was studied.

Climbing plants can assign directly to the surface of a building, or they can be supported on a structure sovereign of the building. The use of climbers that anchor themselves to a structure by twining stems or twining coils enables a green facade to be installed in front of solid walls or some other structure, to create a divider, privacy screen or sunshade. The degree of the mass of the facade coverage can be managed to suit the required function. For example, a facade designed to gloom a building wall would ideally have greater greenery density than a screen installed near a window that is designed to allow at least some degree of views to the environment beyond the facade.

Green facades are often installed because they provide an eye-catching look to a building wall, or they may be used to block out a view, or to afford shade for a building. Green facades can create a cooler microclimate instantly end-to-end to a building, primarily through direct shielding of the building facade, but also from cooling from plant flora (transpiration of water through the leaves), and evaporative loss of water from the growing standard. All climbing plants will provide some retaining of storm-water, shading of the building, protection of its surface, and capture of airborne particulate matter and unstable gaseous pollutants. These benefits will be greater for classic species that retain foliage cover year-round.

For multi-level facades, mainly at height, wind can create major problems for plant attachment. In these settings, twining climbers are ideal over plants that adhere directly to the building facade as the snaking stems attach strongly around vertical and horizontal funds. Shrubbery may still be stripped under extreme wind conditions, so foliage type and size should be matched to the level of revelation and likely wind meters at the site. In general, the higher the planting on a building, the riskier the growing conditions are likely to be. Other factors of importance in multi-level facade design include urn box design (volume, substrate, drainage), maintenance access and irrigation structure design.

Vertical greening

Present-day architecture is increasingly focusing on vertical greening systems as a means to reestablish the environmental integrity of urban areas, biodiversity and sustainability. Vertical greening is the activity of greening the building covering with all forms of vegetated wall surfaces as with plants either fixed into the ground, in the wall itself or in modular panels attached to the façade. Vertical green can be categorized as façade greening or living wall systems according to the mounting method employed. The plant choice affects the aesthetical and practical aspects of a greened façade and many parameters have to be taken into account when picking plant species for vertical greening systems.  These parameters include the subsidiary system type, microclimatic benefits, maintenance needs, biomass production, climate type, and environmental strictures, façade way and limits within the urban area.


Benefits of vertical greening systems

Applying vertical greening systems on both new and existing buildings can offer multiple environmental benefits and a sustainable method in terms of energy saving, nutrients and water management and effective safeguarding of edifices.


The ecological and environmental assistance of green roofs include the perfection of air quality, the reduction of pollution, increased biodiversity and reduction of the heat island outcome in urban areas. Plant’s leaves collect and absorb fine dust particles and transform the carbon dioxide made by traffic & heating into carbon hydrates and oxygen. The reduction of the heat island effect in urban areas befalls thanks to the lower amount of heat re-radiated by greened façades and humidity affected by the evapotranspiration caused by plants as compared to artificial surfaces. This process also allows indirectly saving extensive energy supplied to the building as the plants and the growing medium provide insulation and shade which can reduce energy needed for cooling, expressly in the Mediterranean area.


Vertical greening systems can mend biodiversity as they create a habitat for microbes and also for smaller animals such as bees, bats, birds, etc. Green façades function in this context as a food source (insects) and as nesting or breeding prospect.


In addition the above-mentioned benefits, green roofs and walls also provide economic benefits. Those relate to the real estate market, greater resilience of buildings, and a better psychosomatic state of citizens.


The presence of vegetation in urban areas might affect the economic value of buildings, increase property or rental prices due to the improved visual aspects. Both green roofs and vertical greening structures reduce the frequency of maintenance interventions thanks to a shielding action of leaves against negative effects of UV rays, temperature vacillations, acid rain and air pollution on the fundamental surfaces.


Still, vegetation and green areas are scarce in modern urban environments, where impervious surfaces i.e. traditional building materials, asphalt roads, etc. may cover more than 75% of the entire area. It’s prudent that most of the cities’ surfaces are green because some of the environmental benefits of greening the building envelope only work if a huge surface in the given area is greened.


The greening systems’ design needs to take into account many aspects including the integration with the building envelope, a sustainable substantial choice, the environmental impact, and the relationship between the growing medium and the vegetation, the economics related to costs and budding savings due to the possible reduction of energy required for heating and cooling.

ECO Niwas Samhita 2018 – an Energy Conservation Building Code for Residential Buildings launched

With the growing awareness & the requirement of energy conservation practices, Government has taken an important step to further strengthen the Green Building sector.

Ministry of Power has launched the ECO Niwas Samhita 2018,an Energy Conservation Building Code for Residential Buildings (ECBC-R).The Code was launched on the occasion of National Energy ConservationDay 2018 in the presence of Chief Guest Smt. Sumitra Mahajan, Hon’ble Speaker, Lok Sabha and R.K. Singh, Minister of State (IC) for Power and New &Renewable Energy on 14th Dec 2018.

The implementation of this Code is will give a fillip to energy efficiency in residential sector. It aims to benefit the occupants and the environment by promoting energy efficiency in design and construction of homes, apartments and townships. This Code has been prepared after extensive consultations with all stakeholders, consisting of architects & experts including building material suppliers and developers.


The parameters listed in the Code have been developed based on large number of parameters using climate and energy related data.Initially, Part-I of the Codehas been launched which prescribes minimum standards for building envelope designs with the purpose of designing energy efficient residential buildings.  The Code is expected to assist large number of architects and builders who are involved in design and construction of new residential complexes in different parts of the country. Implementation of this Code will have potential for energy savings to the tune of 125 Billion Units of electricity per year by 2030, which is equivalent to about 100 million ton of Co2 emission.ECBC for commercial buildings was already in place and revised and updated version of ECBC for commercial buildings was launched in June 2017.

The Code is expected to assist large number of architects and builders who are involved in design and construction of new residential complexes in different parts of the country. Implementation of this Code will have potential for energy savings to the tune of 125 billion units of electricity per year by 2030, which is equivalent to about 100 million tonnes of carbon dioxide emission.


It is estimated that energy demand in the building sector will rise from around 350 billion units in 2018 to approximately 1000 billion units by year 2030.While launching this ECBC-R, Shri R.K.Singh stated that building sector will have highest growth in energy demand in coming 10-15 years. Government is encouraging all building professionals including architects, builders to generate awareness towards energy conservation while constructing new residential homes.




Energy Conservation Building Code – A Step to increase Energy Efficient Buildings

Energy Efficiency is word related to the efficient and minimum use of energy so that natural resources can be saved, Ministry of Power initiated and formed BEE (Bureau of Energy Efficiency) in 2002, since then it’s function is to develop programs which will increase the conservation and efficient use of energy in India.

It was formed after the Energy Conservation Act 2001 that was initiated by Govt. of India to promote and tackle the increasing use of Energy Efficiency and promote Energy Conservation.

At first BEE’s Main function was to promote Energy Efficiency and develop awareness about Energy Conservation among the people, initially they come up with giving the standards and ratings to different electronic equipment on the basis of there energy consumption, But later on with the increasing Green Building Movement in India they realised the need for Energy Efficient Buildings in India and create awareness among people about that.

Energy Conservation Building Code (ECBC) was initiated by Bureau of Energy Efficiency, Ministry of Power in the year 2007 to Promote Energy Efficient Buildings in India. Initially, the Buildings which needed to be made according to ECBC were Buildings having a connected load of 500 KW or more but now the Code is applicable to buildings or building complexes that have :

  1. Connected Load in excess of 100kW
  2. Contract Demand in excess of 120 kVA
  3. Recommended for all buildings with conditioned area >500 m2.

The objective of ECBC is to provide minimum requirements for energy efficient design and design of buildings and their systems. ECBC encourages energy efficient design or retrofit of buildings so that it does not constrain the building function, comfort, health, or the productivity of the occupants. ECBC also mandates that the building has appropriate regard for economic considerations. The code sets clear criteria for builders, designers and architects to integrate renewable energy sources in building design through the inclusion of passive design strategies.

The Buildings where ECBC is applicable are :

  1. Large Commercial Buildings
  2. Office Buildings
  3. Large Amenity Buildings
  4. IT Parks
  5. Government Buildings
  6. Hospitals
  7. Retail Malls
  8. Hotels
  9. Major Residential Buildings


The building systems in which ECBC is applicable are:

  1. Envelope of building – Building envelope, including thermal performance requirements for walls, roofs, and windows
  2. Heating, Ventilation and Air Conditioning (HVAC) – HVAC system, including energy performance of chillers and air distribution systems.
  3. Service hot water and pumping – Water heating and pumping systems, including requirements for solar hot-water systems.
  4. Lighting – Lighting system, including daylighting, and lamps and luminaire performance requirements.
  5. Electrical power – Electrical system


This Year Bureau of Energy Efficiency does some amendments in the Energy Conservation Building code and relaunched the code with Energy Conservation Building Code 2017 (ECBC 2017), It was launched by then Minister of Power Mr. Piyush Goyal on 20th June 2017. ECBC 2017 aims to optimise energy savings with the comfort levels for occupants. The code aims to achieve energy neutrality in commercial buildings.

Apart from the current and futuristic advancements in building technology, the new code takes into account market changes, and energy demand scenario of the country. The code has been set in such a way that it will set a benchmark for Indian buildings to be amongst some of the most efficient globally.

To be ECBC-compliant, the new buildings should be able to demonstrate minimum energy savings of 25%. Energy savings of 35% and 50% will enable the buildings to achieve higher grades like ECBC plus or super ECBC status respectively.

The adoption of ECBC 2017 is expected to achieve a 50% reduction in energy use by 2030 which will translate into energy savings of about 300 Billion Units by year 2030. It will result in expenditure savings of Rs 35,000 crore and reduction of 250 million tonnes of CO2.

Apart from the current and futuristic advancements in building technology, the new code takes into account market changes, and energy demand scenario of the country.

Ways to make your Construction smart & Sustainable

Infrastructure Industry is the most Dynamic & Growing Industry in world, but in the way it is growing that is very dangerous for our environment as it is responsible for various reasons  like climate change, resource depletion, pollution, and peak oil. These issues are all accelerating rapidly, and all have strong links with the building industry.

The building industry is hugely dependent on cheap oil, from the manufacture and transportation of its materials, to the machinery and tools used in demolition and construction. In the UK, it uses vast quantities of fossil fuels, accounting for over half of total carbon emissions that lead to climate change. The built environment is also responsible for significant amounts of air, soil and water pollution, and millions of tonnes of landfill waste. This is a situation that clearly needs to change.

Reducing Energy Consumption

With the inevitability of declining fossil fuels, and the threat of global climate change, reducing our energy consumption is an essential survival strategy. Choosing to build green saves energy. The low embodied energy of green products ensures that very little energy went into their manufacture and production, with a direct reduction in carbon emissions. Eco friendly design methodology can further reduce energy consumption by minimising energy inputs for heating, cooling and light, and incorporating energy efficient appliances. Saving energy for the occupant also saves money – an issue that will become increasingly important as the cost of fossil fuels inevitably rises in the near future.

Eco-friendly construction can not only help to create a better outdoor environment, it can also help to build a healthier indoor environment. Conventional building materials and methods have been linked to a wide range of health problems. Chemical pollutants from paints, solvents, plastics and composite timbers, along with biological pollutants such as dust mites and moulds are known to cause symptoms such as asthma, headaches, depression, eczema, palpitations and chronic fatigue syndrome. Green buildings eliminate these problems through good ventilation design, breathable walls, and the use of natural, non-toxic products and materials.

There are many good reasons why we should use eco-friendly construction methods and materials. It can improve the health of our planet, and the health of our own lives. It also supports local business and helps strengthen the local economy, which in turn helps to build our communities into vibrant, prosperous and desirable places to live.


Green building is not only a wise choice for our future; it is also a necessary choice. The construction industry must adopt eco-friendly practices and materials that reduce its impacts, before we reach a point of irreversible damage to our life supporting systems. The UK Government is beginning to recognise this urgency, and is committed to integrating green specifications into building regulations and codes, but the process of developing policy is slow. The industry needs to take its own initiative and find alternative ways to build, using green, renewable energy resources, and adopt non-polluting practises and materials that reduce, recycle and reuse, before it is too late.



1.     Design of Building

Smaller buildings are generally more environmentally friendly and cheaper to run. Intelligent design means making the best use of space possible. It forces developers to start thinking creatively about space, and the future of infrastructure.

2.     Consider The Placement Of Windows

Something as simple as the placement of windows can make a great deal of difference to the atmosphere of a room. Innovative technology for builders assist in identifying the most strategic window positions to take advantage of sunlight and natural breezes.

The problem with poorly sealed doors and windows is they let air flow in and out of the home. This means that your heating and cooling systems have to work harder to keep the house at a constant temperature, which wastes energy and costs you money.

With quality certified windows, you could save $126-$465 per year when replacing single pane windows. When building a new house, choose quality doors and windows that won’t make your heating and cooling system work harder.

3.     Design the Insulation for Building

Insulation is another thing to consider when building an eco-friendly property. Investing in proper insulation keeps the area cool in the hotter months, and warm during the winter, minimising the need to run heating and cooling units regularly.Conventional buildings use insulation materials that contain toxic chemicals such as petrochemicals and toxic adhesives. Sustainable construction presents a range of safe, natural and readily available materials. Some of these materials are more affordable than their commercial counterparts. These materials include sheep’s wool, which is an affordable and sustainable material that can be used as insulation. Others include recycled cotton, which can be sourced from shreds of discarded clothing, representing a sustainable and non-toxic insulation option. Wood fiber can also be used as it is made from wood chips, which are a by-product of the timber industry. The chips are fused together using natural adhesives.

4.     COOL ROOF for the Building

In particularly North & South India, a building’s exposure to the sun can result in heat being trapped inside the roof, gradually warming up the interior of the building. Green roofs (Cool roofs)are an innovative solution to this problem. Heat-reducing methods such as using reflective roof paint, roof covering, tiles, or planting grass will result in a cooler building, and save the energy and money it would otherwise take to cool it.

5.     Assess Durability and Lifespan Of Foundations

Life expectancy in architecture and construction is growing in importance. Durable materials such as brick, stone, and concrete have a longer lifetime and are more eco-friendly during the demolition and disposal phase. Extensions, renovations, and refurbishments stretch the life of a building, especially when structures are built using durable materials.

6.     Use Sustainable, Biodegradable, and Recyclable Materials Where Possible

Reusing old materials where possible is an easy way to save money and reduce environmental impacts of your construction. Products like recycled lumber, plastic, and glass are less damaging than buying new. Biodegradable materials are also being produced with reduced energy costs and pollution.

7.     Water Saving Methods


Conservation of water is a very important element of sustainable construction, be it a residential, industrial or commercial. These strategies are often simple and can be implemented into any kind of construction project. Smart, eco-friendly techniques include rain water collection systems for example. If collected and stored, recycled rain water can be used for things like landscape irrigation. Additionally, water condensation from HVAC units can also be collected and used for similar reasons. Recycling water takes advantage of resources that are readily available, which would otherwise go down the drain.

Reducing water wastage is easily achieved by installing water fixtures to reduce the flow of toilets, showerheads and taps. Encourage clients to purchase eco friendly products by calculating their future water savings.

8.  Install Renewable Energy Sources in the Building

Solar power converts the sun’s radiation into energy. Installing solar panels may be expensive, but in the long run saves a lot of money and energy consumption. However, to take advantage of solar power, location must be considered, as well as the positioning of solar panels. Estimating software assists in determining how much power can be collected and saved.

With soaring energy costs, investing in solar power presents a long-term sustainable solution. Not only will this be a cost-saving measure in the future, solar power reduces your grid reliance and lessens the strain on electricity providers. Solar power transforms roofs of homes and buildings into generators that help to keep power and electricity flowing. To take a step further, photovoltaic windows can with solar cells can be used, creating window panels that adjust transparency and can help to control interior temperatures.

Another option for clean and renewable energy revolves around wind power. Turbine farms of all sizes can be used to help produce energy for any given building. These include vertical axis and helical wind turbines on rooftops which can reduce consumption. The greatest advantage of wind turbines is that they require little maintenance after it is installed. The interior of a building can also benefit from wind turbines, maintaining indoor air quality and reducing utility investments.

9. Locally Sourced Materials

Materials are sometimes transported over a long distance and a lot of energy is used in the transportation phase. With green construction, emphasis is placed on the use of locally-sourced materials. This is meant to reduce the carbon foot print, and creates a far more efficient construction process. Moreover, using materials that are available in any given city or town, construction companies can help support and grow local businesses.



The environmental benefits of eco-friendly construction are obvious. But there are other compelling reasons to implement green building practices that may not immediately come to mind. Examples:

  • Healthier and happier workers: Employees that work in green buildings report fewer headaches as well as improvements in asthma and allergies
  • Reduced energy costs
  • Ability to attract and retain top talent
  • Green buildings are generally able to sell for more money than standard buildings
  • Additional business opportunities by appealing to the ever-growing pool of conscious consumers


Gwalior Fort, Madhya Pradesh

Monday Flashback 22 – Gwalior Fort, Madhya Pradesh



Gwalior Fort was assembled in 8th century by Suraj Sen. The castle stands on a retiring rock known as Gopachal. The fort was governed by many rulers of various reigns who also constructed many palaces and temples esoteric the fort.

History says that 83 generations of the king successfully ruled from this fort but the king of 84th generation named Tej Karan could not shield the fort and vanished it.




Gwalior Fort is one of the colossal forts of India. It includes many structures like palaces, temples, and water tanks. The fort is banquet in an area of 3km and is constructed at a height of 35 feet. There are two gates to enter the fort. One of them is Hathi Pol or elephant gate and other one is Badalgarh gate. Elephant gate is the main entrance to the fort. Many temples are there which are still in use.



Siddhachal Jain Temple Caves


Siddhachal Jain Temple Caves was built thru the period of 7th and 15th century. There are 32 Jain temples in the fort out of which eleven are faithful to the Jain Tirthankaras. The remaining ones are situated in south of the fort. Rishabhanath or Adinath was the first Jain Tirthankara and his ideal is the highest one as its height is 58 feet 4 inch or 17.78m.


Urvashi Temple


Urvashi is a temple in the fortress that consists of many idols of Tirthankaras meeting in countless postures. There are 24 idols of Jain Tirthankaras sitting in the pose of padmasana. Another clutch of 40 idols are sitting in the position of kayotsarga. The number of idols pared in the bulwarks are 840.



Gopachal is a hill which involves of 1500 pin-ups. The size of these ideals series from 6 inches to 57 feet. The era of figure these rock-cut leads is between 1341 and 1479. One of the largest idols is of Bhagwan Parsvanath whose height is 42bases and girth is 30 feet. 3. Gwalior Fort – Temples Gwalior Fort 8


Teli ka Mandir


Teli ka mandir or oilman’s temple is said to have been made in 8th or 11th century and was modernized in 19th century. The temple contains north and south Indian architectural graces. The temple was constructed in quadrilateral shape and people can enter the temple through a set of steps. Gwalior Fort 9 The door of the temple includes the idols of river divinities on top and their guides at the lower part. From the door, disciples cross the threshold the garbha griha. It is said that hitherto the temple was dedicated to Lord Vishnu and was later dedicated to Lord Shiva. The outer and inner part of the door consists of Shaiva and Shakta dvarpalas. The outer walls are carved with the statues of many Hindu gods and goddesses. There is also a Garuda monument near the temple loyal to Lord Vishnu.

Sas Bahu Temple


King Mahipal of Kachchhapaghata empire built Sas Bahu temple also well-known as Sahastrabahu temple. The area shielded by the temple is 32m x 22m. Aficionadas can enter the temple through three gates sited in three different directions. The main idols who are worshipped here are Brahma, Vishnu, and Saraswati and their ideals are located above the admission door. Gwalior Fort 10 The temple is called sas bahu temple because wife of Mahipal used to worship Lord Vishnu while her daughter-in-law used to piety Lord Shiva so another temple was constructed for her.






There are many palaces in the fort which are as tracks:

Man Mandir


Man Mandir palace was built by Raja Man Singh between 1486AD and 1517AD. The outward of the palace was adorned with tiles and the walls include carvings of ducks variable in water. There were large rooms which assisted as a music room for royal women.


Karan Mahal


Kirti Singh made this palace in the fort. He was the following king of Tomar dynasty. Karan Singh was another name of Kirti Singh and so the palace was entitled as Karan Mahal.


Vikram Mahal


Vikramaditya Singh was the hoarier brother of Man Singh. He raised Vikram Mahal which was also known as Vikram Mandir because it had a temple of Lord Shiva which was ruined during the Mughal period. The temple has now been renovated in front of the palace.


Gujari Mahal


Gujari Mahal was built by Raja Man Singh for his queen Mrignayani. She claimed a separate palace with endless water supply. The palace has now been changed into an archaeological exhibition hall. The museum now has weapons, statues, artifacts made of stones and other materials.

deeg palace, deeg, rajasthan

Monday Flashback 21 – Deeg Palace, Deeg Rajasthan

Deeg palace is a marvelous Sustainable piece of Architecture which is situated in the ancient city of Deeg.

Deeg was the capital of the Jat kings before they shifted to Bharatpur. Badan Singh, who came to the throne in 1721. King built a very beautiful palace here. Due to its imperative location and concurrence to Agra, Invaders attacked on Deeg many more times. Badan Sing ’s son, prince Suraj Mal, began the construction of a fortress around the palace around 1730. The fort had massive walls and a deep moat to keep away raiders.

Deeg was a site of a fabulous battle between the Jats and a combined Mughal and Maratha army of 8,000 men. Invigorated by his victory, Suraj Mal began making an invasion into enemy territory. After eight years of success in his sway, Suraj Mal captured Delhi and looted the Red Fort carrying away masses of valuables including an entire marble building, which was demolished and numbered. The palace was then overhauled at Deeg.

The Jat rulers were inveigled by the magnificence of the Mughal courts of Agra and Delhi. The design of the gardens has been inspired by the Mughal Charbagh.

The Deeg palace forms a quadrangle with a garden and walkways at its center. Decorative flowerbeds, shrubs, trees, and fountains cool the place considerably during summer. Two huge water tanks, Gopal Sagar and Rup Sagar, on either side also helped to bring down the temperature.

Keshav Bhawan, the monsoon pavilion, is a single-storeyed baradari placed on an octagonal base. It stands next to the Rup Sagar tank. The erection has five arches along each side which seem to divide it into parts. The walkway runs around the interior of the pavilion over a canal with hundreds of fountains. The walls of the canal are cleave with hundreds of minute water jets. Bullocks were employed with large leather “buckets” to draw water to the tank through a complex pulley system.

In festivals such as Holi, colors are added to the water. Small cloth pouches with biological colors were manually inserted into the holes in the stockpile wall. When the water flowed through them passing along an intricate network of pipelines, the fountains cascade colored water. Deeg Palace with its 900 fountains, which operate twice a year during the avamasaya festivals in February and September months.

The fountain spray and the jets create a monsoon-like atmosphere that is enhanced by a unique technique that produces a thunder-like sound all around the pavilion. Hundreds of metal balls placed strategically on the channel surrounding the roof are set rolling with the water pressure which results in a thunderous effect. The ambiance in a desert town must have been momentous for the Jat kings and queens.

King’s bedroom contains a massive black granite bed of the Maharaja. It had once served as a part of Parsi death rites, functioning as a platform for washing dead bodies.



The architecture of Deeg is mainly represented by the mansions called the Bhawans popularly known as Gopal Bhawan, Suraj Bhawan, Kishan Bhawan, Nand Bhawan, Keshav Bhawan, Hardev Bhawan. The striking features of these palaces are a balanced synopsis, fine proportions, commodious halls, attractive and logically disposed of arcades, charming greenery, charming tanks and canals with fountains. The layout of Deeg gardens is based on the formality of the Mughal Char bagh or fourfold garden patterns and belted by two reservoirs called namely Rup Sagar and Gopal Sagar.

The architecture is primarily of trabeate order, but the use of the arcuate system has also been made in certain instances. Mostly the arcades are of a decorative quality as each arch is formed by joining spandrel shaped slab cantilevers projecting from the pillars. The general features of this style are engrailed arches resting on rococo pillars, hypostyle halls flat roof terraces, balconies and pavilions with Bengal roofs, double eaves, moderate structural heights, and spacious subjective arrangements.

Deeg palace is a marvelous Sustainable piece of Architecture which is situated in the ancient city of Deeg.

rumi darwaza, lucknow

Monday Flashback 20 – Rumi Darwaza, Lucknow

RUMI DARWAZA – “A SYMBOL OF LUCKNOW’S TRYST WITH DESTINY” and a Unique Sustainable Structure in the City of Nawabs.

Rumi Darwaza was built by the fourth Nawab of Lucknow, Nawab Asaf-ud-Daula in 1784-86 and is believed to be similar to an old gate in Istanbul called Bab-iHümayun, and so is also sometimes referred to as Turkish Gate.

The 60 feet high gate is known for its architectural beauty, built for a noble cause. In 1748 North India, particularly Awadh, was facing the scarcity of food and employment and survival of most of the population was at stake. To help people overcome this Nawab Asaf-ud-Daula decided to build the Bara Imambara along with Rumi Darwaza for employment generation. Over the next two years, these illustrious buildings were constructed and is now there for everyone to see. This building symbolizes labor of love i.e. was constructed for pleasure and for no reward.

The architectural style of the Rumi Darwaza is completely in sync with the Nawabi architecture of Lucknow. The material used for the Darwaza is bricks coated with lime. The detailing on the Darwaza is more embellished thereby making it mesmerizing to see.

It is a huge sumptuous structure, marked by an eight faceted chhatri (umbrella) in its uppermost part that can be accessed by the staircase. In earlier times it was used to mark the entrance to the Old Lucknow City.

The most breathtaking about  Rumi Darwaza is lantern kept at the top that would light up the structure at night making it look thrillingly beautiful. Water sprinklers that rush out of the sides of the arch are in form of beautifully carved flower buds thus making it look like a passage to heaven. The beautifully carved flowers and designs speak volumes about the unique architectural style and eye for detail. The Rumi Darwaza is truly a grandeur and must visit if you are traveling to Lucknow.

The word “Rumi”  was derived from the modern day Rome that used to be Istanbul, the capital city of Eastern Roman Empire.

The Rumi Darwaza has become the existing symbol of Lucknow, depicting the royal Nawabi Culture, whether it’s tourism promotion or simply building a brand for the city.




Monday Flashback 19 – Maha Bodhi Temple, Bodhgaya Bihar

A unique property of cultural and archaeological importance and is also recognized by  UNESCO as World Heritage site in the world that spread over an area of 4.86 hectares. It is a great example of the earliest buildings which have sustained till now. The first temple was built by Emperor Asoka in the 3rd century BC (260 BC) around the Bodhi Tree, i.e. Ficus religiosa (to the west of the temple). Revered and sanctified as the place where Siddhartha Gautama Buddha was enlightened in 531 BC at age 35, and then propagated his divine knowledge of Buddhism to the world, it has been the ultimate temple for reverential worship, over the last several centuries, by Buddhists of all denominations, from all over the world who visits on pilgrimage. The main temple is 50 m in height, built in Indian architectural style, and it is the oldest temple in the Indian sub-continent built during the “Golden Age” of Indian culture credited to the Gupta period. Sculpted balustrades of the Asoka times (3rd century BC) are preserved in the Archaeological Museum located within the temple complex. It is considered to be a fine example of Indian brickwork, and was highly influential in the development of later architectural traditions.

In approximately 250 BCE, about 200 years after the Buddha attained Enlightenment, Buddhist Emperor Asoka visited Bodh Gaya with the intention of establishing a monastery and shrine. As part of the temple, he built the diamond throne (called the Vajrasana), attempting to mark the exact spot of the Buddha’s enlightenment. Prior to that, there seems to have been a pyramidal structure perhaps built in about the second century (Kusana period). Knowledge of it comes only from a small, circa fourth century terracotta plaque found at modern Patna. The pyramidal temple probably replaced an open pavilion that had been constructed around the tree and the Asokan platform, during the reconstruction.

The four towers on the corners rise elegantly, escorting the main tower to an extent. Encircled on all four sides by stone railings, Mahabodhi Temple bears railings of two types, equally in style and material. The older railings are made from sandstone and trace their origin around 150 BC. Dating back to Gupta period (300 CE – 600 CE), the other railings are erected from unpolished coarse granite. The old railings comprise images of Hindu deities, while the later ones have got figures of stupas (reliquary shrines) and garudas (eagles).

Building Sustainable Materials that are used in the building –

  1. Brick-  Brick structure assemblies possess two unique characteristics – usually not accounted for in R-value measurements –     that significantly contribute to energy performance and reduce energy costs. These properties are Thermal mass and airspace.
  2. Sandstone- This stone is very eco-friendly

  •  It has a relatively low carbon footprint as it uses a very small percentage of the energy needed to stone like concrete or brick.

  • No chemicals are used in the production or processing of sandstone, so it does not create any chemical waste. All water used in producing the stone can be recycled and reused.

  1. Granite- Granite & marble are highly recyclable and reusable, as well as durable.

Suggested Improvements & Solution-

Use of footwear is banned on the shrine premises and the devotees have to walk through extremely hot marble during the summers and in winters the marble floor is extremely cold. The pathway was slippery too.

Mahabodhi Temple premises are carpeted with artificial grass. Besides giving a more serene look to the seat of  Budhha’s enlightenment, the synthetic grass carpet will provide relief to barefooted devotees.

Important Features of Mahabodhi Temples-
