PM Modi calls for 100 day Campaign for water conservation

Prime Minister Narendra Modi said there was a need to start conserving water right away and that the Jal Shakti Ministry would be launching a 100-day “catch the rain” campaign soon right from 1st March 2021 onwards.

Mr. Modi was speaking during his monthly radio address, Mann Ki Baat, when he said there was a need to have collective responsibility with regard to water conservation.

“In most parts of India, rainfall begins in May-June. Can we right away start a 100-day campaign for the sake of cleaning up water sources around us and conserving rainwater? With this very thought in mind, in a few days from now, Jal Shakti Abhiyan ‘catch the rain’ is being initiated by the Jal Shakti Ministry,” he said, according to the English translation of his address provided by the government.

Prime Minister Narendra Modi on Sunday said there was a need to start conserving water right away and that the Jal Shakti Ministry would be launching a 100-day “catch the rain” campaign soon.

In this regard, the Union Jal Shakti Ministry is also launching “Catch the rain” campaign and its main theme is “catch the rain, where it falls, when it falls”, he said.

“This is the best time to think about water conservation in the summer months ahead,” Modi said.

Let’s work together in this regard and support in water conservation & harvesting and prepare ourselves for the Extreme summer and then harvest the water during the Monsoon season.

Urban Heat Island Effect and how to mitigate their effects!

“Urban heat islands” occur when cities replace natural land cover with dense concentrations of pavement, buildings, and other surfaces that absorb and retain heat. This effect increases energy costs (e.g., for air conditioning), air pollution levels, and heat-related illness and mortality.

Climate change will likely lead to more frequent, more severe, and longer heat waves during summer months.

  • The city of Chicago could see 30 more days per year rise above 100 degrees Fahrenheit (°F) under “high” greenhouse gas emissions scenarios.
  • Under lower emissions, Chicago’s new summer heat index could increase to around 93 °F by the end of the century—similar to current summer conditions in Atlanta, Georgia.

City officials worry that intense summer heat could lead to uncomfortable conditions for residents, as well as reduced tourist attraction in summer months.

Extreme heat events often affect our most vulnerable populations first.

Trees, green roofs, and vegetation can help reduce urban heat island effects by shading building surfaces, deflecting radiation from the sun, and releasing moisture into the atmosphere.

Elevated temperatures from heat islands can affect a community’s environment and quality of life in multiple ways.

Increased Energy Consumption

Heat islands increase demand for air conditioning to cool buildings. In an assessment of case studies spanning locations in several countries, electricity demand for air conditioning increased approximately 1–9% for each 2°F increase in temperature. Countries where most buildings have air conditioning, such as the United States, had the highest increase in electricity demand.This increase demand contributes to higher electricity expenses.

Heat islands increase both overall electricity demand, as well as peak energy demand. Peak demand generally occurs on hot summer weekday afternoons, when offices and homes are running air-conditioning systems, lights, and appliances. During extreme heat events, which are exacerbated by heat islands, the increased demand for air conditioning can overload systems and require a utility to institute controlled, rolling brownouts or blackouts to avoid power outages.

Elevated Emissions of Air Pollutants and Greenhouse Gases

As described above, heat islands raise demand for electricity in summer. Companies that supply electricity typically rely on fossil fuel to meet much of this demand, which in turn leads to an increase in air pollutant and greenhouse gas emissions.

These pollutants are harmful to human health and also contribute to complex air quality problems such as the formation of ground-level  (smog), fine particulate matter, and  acid rain. Increased use of fossil-fuel-powered plants also increases emissions of greenhouse gases, such as carbon dioxide, which contribute to global climate change.

In addition to their impact on energy-related emissions, elevated temperatures can directly increase the rate of ground-level ozone formation. Ground-level ozone is formed when nitrogen oxides and volatile organic compounds react in the presence of sunlight and hot weather. If all other variables are equal, such as the level of precursor emissions in the air and wind speed and direction, more ground-level ozone will form as the environment becomes sunnier and hotter.

Compromised Human Health and Comfort

Heat islands contribute to higher daytime temperatures, reduced nighttime cooling, and higher air pollution levels. These, in turn, contribute to heat-related deaths and heat-related illness such as general discomfort, respiratory difficulties, heat cramps, heat exhaustion, and non-fatal heat stroke.

Heat islands can also exacerbate the impact of naturally occurring heat waves, which are periods of abnormally hot, and often humid, weather. Sensitive populations, such as children, older adults, and those with existing health conditions, are particularly at risk during these events.

Excessive heat events, or abrupt and dramatic temperature increases, are particularly dangerous and can result in above-average rates of mortality. From 2004 to 2018 the Centers for Disease Control and Prevention recorded 10,527 heat-related deaths in the United States, an average of 702 per year. These numbers include deaths where heat was the underlying cause and deaths where heat was a contributing cause.

Impaired Water Quality

High temperatures of pavement and rooftop surfaces can heat up stormwater runoff, which drains into storm sewers and raises water temperatures as it is released into streams, rivers, ponds, and lakes. Water temperature affects all aspects of aquatic life, especially the metabolism and reproduction of many aquatic species. Rapid temperature changes in aquatic ecosystems resulting from warm stormwater runoff can be particularly stressful, and even fatal, to aquatic life.

One study found that urban streams are hotter on average than streams in forested areas, and that temperatures in urban streams rose over 7°F during small storms due to heated runoff from urban materials.

Green infrastructure is one option to cool stormwater runoff and improve water quality. It can include the use of downspout disconnections, rain gardens, planter boxes, bioswales, permeable pavements, green streets and alleys, green parking, and green roofs; as well as land conservation efforts.

To reduce the urban heat island effect:

  • Build green infrastructure improvements into regular street upgrades and capital improvement projects to ensure continued investment in heat-reducing practices throughout your community.
  • Plant trees and other vegetation—Space in urban areas might be limited, but you can easily integrate small green infrastructure practices into grassy or barren areas, vacant lots, and street rights-of-way.
  • City officials in Louisville, Kentucky, recently awarded a $115,700 contract for a tree canopy assessment to help the city use trees to address urban heat, stormwater management, and other concerns. “Knowing where we lack canopy, down to the street and address level, will help our efforts exponentially,” remarked Mayor Greg Fischer.
    • Make traditional water quality practices serve double duty by adding trees in or around roadside planters and other green infiltration-based practices to boost roadside cooling and shading.
    • Transform your community one project at a time by planting native, drought-tolerant shade trees and smaller plants such as shrubs, grasses, and groundcover wherever possible.
  • Build green roofs—Green roofs are an ideal heat island reduction strategy, providing both direct and ambient cooling effects.  In addition, green roofs improve air quality by reducing the heat island effect and absorbing pollutants.

Green technology is essential for Future Construction

Builders all over the globe are gravitating towards greener technology methods that can make buildings energy-efficient and sustainable. Homeowners are also showing interest in projects that deploy raw material and construction techniques with a lower carbon footprint and that are not detrimental to the environment. These techniques are being extensively used in modern construction right from the inception phase and in every aspect of the project construction; design, selection of raw material, the systems that run the construction, and the operation.

Renewable power

Renewable energy sources help in the creation of self-powered buildings. These structures generate their own power to support their energy requirement. In most cases, it is done through solar and wind power. The use of solar power isn’t a new technology. It has been around for long, but now it is widely used by builders as an effective and green alternative to traditional energy sources. 

Using the sun’s energy in active solar power generation involves using the solar panels to generate electricity. Passive solar power generation, on the other hand, uses the sun’s rays to heat the houses using the strategic placement of windows and heat-absorbing surfaces. Wind power is being used by skyscrapers that have wind turbines mounted on the rooftops. The strong air currents at high altitudes propel the turbine blades which results in the generation of power.

Green Insulation

Thermal insulation of a building plays a very important role in improving the quality of life of the people residing or working there. Using hollow clay bricks like the Porotherm Thermo bricks is one such greener technology innovations in the field of modern construction for green insulation. These bricks are eco-friendly, made from easily available raw material that is clay, and rank high on the sustainability meter. 

Sustainable raw material

Using bio-degradable raw material is one of the ways of creating a sustainable structure. A lot of waste products and toxin materials are generated during the construction of a building. This waste piles up in landfills for centuries before degrading. We can avoid this by going in for bio-degradable raw materials like bamboo, recycled glass, and organic paints. A relatively newer but effective sustainable material that can be used is eco-concrete. It is practical, durable, strong, and acts as an air purifier with its smog-eating properties. These raw materials do not pose any threat to the environment and improve the productivity and health of people. 

Water-efficient systems

Pic Credits: https://www.homeonline.com/hol/home-tips

Using water-efficient technologies in the construction process is one of the green and sustainable ways of making the structure adhere to green standards and green technology. These technologies include re-use and application of efficient water supply systems and deploy methods like rainwater harvesting, dual plumbing, grey-water re-use, and water conservation fixtures. The use of these water-efficient technologies can lower water wastage by as much as 15%.

Cool roofs and smart glasses

Pic Credit: https://energyhawksusa.com/

Cool roofs reflect more of the sun’s rays than other roofs and prevent the warm or cool air inside from escaping through the top of a building. A cool roof keeps the temperature inside a building low (a cool roof can cut that down by more than 50 degrees) that reduces the strain on the air conditioning systems. This, in turn, reduces the emissions from the heating and cooling units. 

Smart glass is an electrochromic glass that uses a tiny burst of electricity to charge ions on a window layer. It controls the amount of light that the glass will reflect. It is different from the low emittance windows that block partial radiation of the sun as with smart glass, you can choose the amount of light you want to block. This technology is especially beneficial for skyscrapers that use a lot of glass in their façade. The smart glass windows tint automatically during peak sun hours and become transparent in the evenings, night. This glass is expected to reduce HVAC costs by almost 25 %.

A structure becomes great not only by its design but also by its impact on the environment. It is time for the buildings to enter into a symbiotic and healthy relationship with the environment by using green technology-based construction methods.

Realty about the Pollutants in composting, Myths and Facts!

The commercial success in the era where we have to take serious steps towards safeguarding environment is taking wrong twist and turns. The recent awareness about composting the organic waste in decentralized manner has picked up the momentum. As a hungry commercial monster human being is also defying the process of natural composting by accelerating it. We want to have compost in 48 hours, 24 hours and I just now read in one of the brochure claiming 15 minutes.

We don’t think twice while wasting and throwing the valuable food along with food waste. But while taking efforts to bring it back in circular economy of sustainability we want to be God of Gods.

In the wake of government orders and notifications of managing wet wastes by commercial complexes and residential societies at local level in decentralized manner some of the commercially eccentric product manufacturers are spreading claims of creating compost in as low as 15 minutes time. Machines rating 1.8kW till 200kW to convert waste to compost in such a short time. And what they claim is following

  • The organic waste is segregated
  • Segregated waste is shredded to small size
  • The shredded pile is then forcibly dried using electrical or oil heaters.
  • The dried powder is said to be ready to use compost or some suggest then to keep it for curing for another 20 days with bacteria.

Now try to analyse above steps this way –

  • The organic waste is segregated

This is a right step and must be done manually at source itself by the user or the person who is dumping it in the garbage bin.

  • Segregated waste is shredded to small size

This is a step to accelerate the process of decomposition and can be used to help reduce overall size of waste also in terms of storage capacity.

  • The shredded pile is then forcibly dried using electrical or oil heaters.
  • The overall shredding process will make the waste a lot wet as the water in the matter is now out of the body so there will be leachate with highly acidic form and bad odor.
  • 70-80% of organic waste is water which has to be dried now.
  • Assume following –

Q – is the energy require to raise 1 Celsius of 1 kg o substance

c – is the specific heat o a substance

m – is the mass of the substance

θ – is the difference of temperature of a substance ( temperature of a substance after energy is absorb – temperature of a substance before energy is absorb)

We want to find Q so, the specific heat of water is 4.2 J/kgC-1 . I assume that the mass of the water is 1 kg coming out of the waste. The temperature difference in order to evaporate water is about 70°C (100°C – 30°C assume that room temperature is 30C) we substitute all in the equation –

Q = (4.2*103 J/kgC^-1) (1 kg) (70°C) = 294000 J

So 294000 joules of energy is require to evaporate 1 kg of water, which is about 0.09kWh energy per kg of water

The survey on net shows India produces over 60 million metric tons of waste a year out of which over 60% is organic waste. Currently only 9% of this waste is treated at source, the rest ends up choking landfills and our cities.

This means 32760000000kg of organic waste remains to be treated

Assume only 30% of this is treated for composting using such forced drying machines = 9828000000kg and this will require (9828000000kg*70%) of water*0.09kWh = 619164000kWh of electrical or fuel energy. Hopes this helps:) to know cost of energy and load of energy in converting wet waste to compost.

There is an alternative way of such decentralized composting

The other problem in the heating to dry the organic waste is even though the temperatures are lesser than burning temperatures the localized heat accumulation and low temperature exposure for extended time will tend to partially burn the organic matter.

Such reaction at lower temperatures have a very harmful ratios of CO-CO2 and Nox gases. (Reference: Pollutant Formation in Combustion Processes, Grzegorz Wielgosiński, Technical University of Lodz, Faculty of Process and Environmental Engineering, Poland)

While this partial drying / burning we are losing the nutrient value of the end compost.

The dried powder is said to be ready to use compost or some suggest then to keep it for curing for another 20 days with bacteria.

The dried powder is not a compost it is just forced stage of organic matter. Such dried powder is very hygroscopic. It will quickly absorb moisture from air and soil and again get into non-composted organic form.

Which will now rotten in the open soil. This is also a good food of flies and insects hence they breed in this form of powder when wet. This will start smelling foul as it becomes wet again.

It will take another 8-10 days minimum in open natural environment to get to a form where the plantation can absorb anything out of it.Improperly disposed organic waste is a major contributor to global greenhouse gas emissions, at almost 1500 Tg CO2 / year. Waste deposited, partially burnt emits methane which contributes 21 times the global warming impact of carbon dioxide according to the concept of Global Warming Potential adopted by the UN Framework Convention on Climate Change (UNFCCC).

The composting has to be self driven acted by assisted by the bacterial culture. The bacteria will chemically break down the waste in desired form by digesting some part as food for themselves. While such digestion the bacterias will generate a good temperature on their bodies which will dry out the waste naturally to the extent that some times you have to add some water to keep the bacteria’s active.

The process only demands small area in your garden or parking or terrace and a manpower for a size of 100 homes or equivalent waste processing setup.

Make this Diwali, Green-Wali by following eco friendly ways

The festival of light and delight is finally here and everyone is in high spirits to celebrate Diwali. Every year, this festival is celebrated with great zeal and excitement by one and all. However, many people think that it is perfectly alright to turn this celebration into the festivities of pollution and misuse of resources. 

Diwali is not about making the world a more polluted place, it is about celebrating the arrival of Lord Rama after his glorious victory against Lanka king Ravana.

  1. Instead of opting for electric lights this Diwali, you can go for handmade earthen diyas. It is not just a heartfelt gesture but also a great way to celebrate the festival in an eco-friendly way.
  2. Use dried leaves and flower petals to make a rangoli. It is a biodegradable way to create a festive design and very cost-effective as well.
  3. Avoid using crackers altogether if you can. For a cleaner and greener future we need to stay away from crackers altogether, but if you still want to go ahead with it then you can opt for green crackers.
  4. Instead of plastic decorations, choose either paper decor or you can even opt for bamboo decor. 
  5. This festive season, you must opt for handmade paper wraps for your gifts instead of plastic wraps. It is one of the most eco-friendly ways to celebrate Diwali.
  6. Always make sure that you recycle the items that you can. If you have old candles lying around or old decorations in the house, then don’t shy away from using them.
  7. If you are hosting a Diwali bash this season, then instead of plastic plates and other cutlery, use biodegradable things instead. It will make a huge difference.
  8. Diwali means Diwali cleaning, so make sure you dispose of the waste in an eco-friendly way.

Meet the Young innovators who created the briquetting machine to manage the agri waste

We are in the 21st Century today, where we utilize all the advanced technologies and yet, if you go out into rural India, you find a totally different scenario. Rural India has a lot of undiscovered wealth. If you look at the current scenario in the villages, you find that there are a lot of resources such as agri-waste generated in the farms, sawdust, waste paper, cow dung cakes etc., which is seen as just waste due to lack of proper knowledge about its potential.

Agri-waste management in rural farms

In contrast, waste management has always been a herculean task in urban cities, while in villages, it is totally neglected. Household garbage and agri-waste either ends up piled on the roads or burnt carelessly as there is no proper solid waste management system in place. This leads to a lot of pollution. Despite various schemes by the government to provide LPG connections at subsidized prices, rural women tend to use firewood for cooking, which has a lot of ill effects on their health and also the environment. On the other end, there is a lot of agro-waste being generated in farms. Can’t there be a solution that helps the rural communities to turn the waste into a resource?“Yes, it can be”, emphatically says Darshil Panchal, Managing Partner of S K Engineers. Darshil pursued Master of Science in Industrial Engineering from New York University, USA and returned to India to join his family-owned company, S K Engineers. Established in 2011 by a group of technocrats, it is a company based in Vapi Industrial Estate, Vapi, Gujarat.

During his company’s work with NM Sadguru Foundation, Darshil worked closely among rural communities and observed the lack of a reliable source of cooking fuel. In the search for a solution to this problem, Darshil came across boilers that used briquettes instead of coal. Agricultural waste is being generated in abundant quantities was procured from the rural communities by briquetting plant owners who in turn make briquettes out of it and supply it to boiler plants. On the other hand, rural farmers burn away the agricultural waste generated at their farms without realizing its potential.

Understanding this, Darshil ideated on manufacturing a manual version of a briquetting machine to manage agri waste, which could prove to be a boon to rural India, especially women. Since   S K Engineers work closely with various NGOs and voluntary organizations that work for the cause of rural upbringing, they came up with an appropriate solution for the effective management of various types of waste such as agro waste, fodder, kitchen waste, paper/plastic/cardboard waste, etc.

S K Engineers innovated three different models of the manual briquetting machine:

  • Briquetting Lever Press – ‘BLP’
  • Briquetting Jack – ‘B-JACK’
  • Briquetting Hydraulic Jack – ‘B-HACK’

Briquetting machine to manage agri waste

All kinds of household and agro-waste material such as kitchen waste, sawdust, fodder, cow dung, trash paper and others are first shredded into tiny pieces. This mixture is then blended together with little water and cow dung to create a slurry. Once the slurry is ready, it is poured into the cylindrical cavity of the BLP machine and the lever is pressed to start the compression process. Then the compressed slurry is removed and dried in the sun and the briquette is ready. These briquettes can be directly used at home as an alternative fuel for cooking or can also sold in the market at a price of INR7-10 per kg to earn extra income.

Product Company Named as S K Engineers.

The briquettes produced are pretty light in weight and can easily be stored or transported. Compared to uncompressed waste, briquettes burn comparatively for a longer duration. This lightweight machine can be easily installed by anyone at any place and also be dismantled for transportation. The ready waste available at farm location becomes the raw material and input to this machine and various briquettes are formed. So, BLP brings extra income to rural families and improves their economic condition.

Daily production40 Kg64 Kg90 Kg
Price (with GST)INR15,500INR21,000INR28,000

Quoted capacity is for 2 manual laborers working 8 hours per day

Working closely with rural communities helped S K Engineers to fabricate a few more innovative machines:

  1. Manual Dry Powder Blender (Required for mixing of dry powder)
  2. Manual Baler Machine
  3. Manual Nursery Seeder Workstation

They designed these handy equipments with the following properties:

  • Power: No electricity requirement
  • Mobility: Compact enough to easily store & transport
  • Lightweight: Can be lifted with ease even by women (BLP only)
  • Negligible after-sales service expenses on the customer side
  • Briquette size: Large enough to burn for comparatively long time
  • Design: The products are specially engineered to suit the purpose

Manual Baler Machine

Generally, plastic waste, multi-layered plastic packaging, paper waste, cardboard, farm waste etc., do not have much value since they are too bulky to transport easily. Understanding this problem, Darshil Panchal innovated a new type of manual baler machine that helps to effectively manage waste and transport them in an organized way. This product can be used by any waste recycler or rag picker communities to manage waste in an organized manner and sell it to companies to earn more income.

This Manual Baler Machine can be easily transported since it has the provision of wheels. It is easy to operate and highly economical as there is no maintenance required for it. Effective compression enables it to remove voids and compress the maximum amount of waste material which in turn helps in the reduction of empty space during transportation.

Tech Specs for Manual Baler Machine

  • Average size of waste that can be baled – 600 mm x 600 mm x 600 mm
  • Bale weight – upto 40 Kg
  • Time taken to produce one bale – 10 minutes
  • Daily production – 1,280 Kg
  • Price – INR30,000

These machines are unique since they need no electricity and very less manual power and are easily installable & operable. With the Briquetting machine, the agri waste is turned into resources and used as cooking fuel and also earn income by selling the excess briquettes produced. And the Baler machine is another income generator as the waste is managed and transported effectively. The only resource needed to put in is human energy. Not much financial capital is required for setting up the machines.

Already numerous NGOs and rural development organizations have bought these machines and utilized them for waste management and income generation.

Let us check some Water Harvesting Methods from our Ancient Times !

India is home to 18 percent of the total world’s population, but it has access to only 4 percent of the world’s freshwater resources. Reports by the think-tank of the Indian government i.e. NITI Aayog states – India is facing the vilest water crisis in its history. This 2018 report predicts, 21 Indian cities, including major metros like Delhi, Chennai, Hyderabad, and Bangalore will run out of groundwater by 2020. This situation is extremely alarming, as 2020 is just a few months away.

The drought situation in few parts of the county, in times when good monsoon showers are expected mirrors clearly that waning climate change is all set to cause mayhem. By now, most of the parts of the country should have been experiencing good amounts of rainfall but the reality is far more disturbing. Severe drought threatens the country, and poor infrastructure is making it worse. But there are potential solutions one of which is ‘Catching the Rains’ with different types of rainwater harvesting systems.

Rainwater Harvesting – What Is It?

Rainwater harvesting is a technology used to collect, convey, and store rainwater from relatively clean surfaces like the roof, rock catchment, or land surface – essentially for later use. This collected rainwater is either directed to recharge groundwater or stored in a rainwater tank.

Rainwater harvesting isn’t some modern technology, it has been practiced for over 4,000 years throughout the world. Traditionally in arid and semi-arid areas, rainwater harvesting systems have provided water for domestic use, drinking, livestock, and small irrigation purposes. Today, rainwater harvesting is gathering a lot of significance as a modern, water-saving and simple technology.

Why Rainwater Harvesting?

In many regions across the globe, clean drinking water is not easily and readily available. For potable water, huge investment costs and expenditure is needed. Rainwater is one free water source and comparatively clean; with proper treatment, it can be used for several non-potable uses. Rainwater harvesting relieves the pressure on sewers and the environment by mitigating floods, soil erosions and replenishing groundwater levels; also it helps in saving the high-quality drinking water sources by reducing the consumption of potable water.

There are so many reasons why we should start collecting rainwater. From doing our part for the environment and saving money on water bills to having constant access to water – collecting rainwater can be beneficial in so many ways.

ReadRain Water Harvesting – Why, Benefits, Techniques & More

7 Different Types Of Rainwater Harvesting Systems

Below mentioned are the different types of rainwater harvesting systems:

1. Water Butt

One of the most basic types of rainwater harvesting systems; water Butt collects rainwater in a container from natural rainfall and/or drain pipes. The collected water is used mainly for watering the garden.

2. Direct-Pumped

Another very common and professional type of rainwater harvesting.

  • Submersible – Used particularly in domestic settings and is the easiest systems to install. The pump is placed within the underground tank and the harvested water is pumped directly to WCs or other appliances used daily for domestic purposes.
  • Suction – In this system, the pump is located within the control unit of the house (e.g. utility room). This unit also deals with backup from the mains water supply, hence there is no need to direct mains water down to the underground tank.

Most rainwater harvesting systems need pumps to transfer the collected rainwater from storage tanks to the point of use. Submersible pumps are generally more efficient than suction pumps and do not suffer from the same limitations.

3. Indirect Pumped

This type of rainwater harvesting system doesn’t rely on gravity to supply water to the outlets. Instead, it pumps the harvested water to a tank which can be at any level in the building. Furthermore, a booster pump is used to provide a pressurized water supply. One of the most significant benefits of this system is that it offers great flexibility to tailor the booster pumps to adjust the flow and pressure requirements of a building.

4. Indirect Gravity

This system ensures water is supplied to the outlets by gravity alone. For this, the harvested water is first pumped to the header tank, i.e. high-level tank and then allowed to free-flow. In Indirect gravity systems, the pump works only to fill the header tank.

5. Gravity Only

In few conditions, a system which functions purely through gravity may be needed. Such systems do not demand pumps hence involves no energy use. With such an arrangement, water can be collected only when collection tanks are located below the level of gutters, yet higher than the outlets which it will supply. Here the only power of gravity is needed to feed collected and harvested water to various parts of the household. Gravity only is one of the most energy-efficient rainwater harvesting systems.

6. Retention Ponds

Retention ponds are used to collect surface runoff water and improve the quality of water by natural processes like sedimentation, decomposition, solar disinfection, and soil filtration. This type of pond normally has a mud bottom, but in some cases, it may be lined with concrete. The most common use of water collected and harvested by pond harvesting is watering livestock, however, it can also be used for groundwater recharge, irrigation or any other purpose other than potable uses.

7. In-Ground Storage

Underground storage tanks are very popular in areas where the majority of rainfall occurs in one single season. These underground tanks are insulated and have a very low rate of evaporation. In addition, the water stored in these doesn’t freeze if it is buried below the frost line, this is a huge advantage that surface storage tanks do not offer. Underground tanks need to be connected to an electric pump to ensure supply of the stored water to the outlets.

Rainwater Harvesting Is Crucial For The Future

It is the human’s unfriendly attitude towards nature which has poisoned our water-bodies and turned them unfit for any use. We are stretching our local water resources to provide for the exponential population growth and economic development. Turning to new water supply strategies and paradigms are indispensable to meet this demand.

Today most of the parts of the world are facing scarcity of water, taking up rainwater harvesting is necessary for survival. Natural resources come in abundance but they cannot be produced – attempts need to be made to collect and harvest it at an individual level.

So our efforts are towards raising the awareness about sustainability and green construction, which is an alternative solution for using resources in the most efficient manner.

Our intention of having a community of stakeholders, architects, consultants, and manufacturing companies is this only, so under a single Econaur’s green buildings platform anybody can communicate with anyone and know what more can be achieved in sustainable construction. We believe in working together, and no better way can be there to connect every member from the building industry at a single platform.

How we do it?

The major thing we keep in mind before showcasing any information or product on our platform is that, the product doesn’t have any harmful impact on the environment. As long as the product is sustainable and minimize the harmful effects on the environment, we are always whole-heartedly open to showcase the product.

Even if you want to share any information or post anything related to green building, new sustainable products or about environment then also we give you a community article section where you can share anything related. Not only you can share but come to know about more sustainable innovations going on all around the world.

We personally too share regular content in our blog section about new technologies, construction products and news about the green building.

Perhaps you ask, ‘How can I afford green building materials?’Although you may be on a tight budget, there are creative ways to build a green home or office without compromising quality. We’re aware of the challenges and invite you to take advantage of our expertise in order to get the look and quality you want, at a price you can afford. We’ve done it with our own home and with hundreds of others — and we’re confident we can help you, too.

How do eco-friendly and sustainable products compare in cost to toxic products?

As a rule, natural and non-toxic products (e.g. wood, bamboo, cork, wool carpet, natural linoleum, marble/granite/limestone/porcelain, natural finishes, etc.) tend to be our favorites. They are sometimes more expensive than other products initially, but that’s not the whole story.

Sustainable products tend to:

  • last longer
  • wear better
  • clean easier
  • smell better
  • create a pleasing, healthier environment for residents
  • be biodegradable

Non-sustainable products, on the other hand, tend to:

  • be short-lived
  • require more maintenance
  • exhibit toxic and foul smells for many months, with some out-gassing undetected for years
  • compromise the health of individuals and the environment
  • provide only short-term pleasure
  • sit in landfills almost forever

In the long run, the life-cycle costs of sustainable products are usually less expensive. Plus they bring greater satisfaction during installation and for generations of use.

Many of our clients forced us to find natural products that would compete in price with cheaper, unnatural products. This was a challenge, but we did it.

A new trend

Non-toxic products used to be more expensive to manufacture than their toxic counterparts. This was due, in part, to the newness of the products and the small numbers of people using them. This trend has changed in the last few years; prices have fallen due to the widening market and the improvement of manufacturing techniques.

Demand for environmentally-friendly products is at an all-time high, not only in the building market but in the clothing and food markets as well. As the world wakes up to the lasting value and joy of using healthy building materials, we fully expect this trend to continue for a long time to come.

In addition to understanding the nature of eco-products, we’re also involved on the local level in using these products to help build a sustainable future. We promote healthy building environments in several ways including belonging to trade and environmental associations, sponsoring conferences, earth days and eco-fairs, donating a portion of our earnings to non-profit organizations that create peace and better the environment, and consulting with clients nationwide who personally test and use green building products.

Comments and Suggestions 

If you still have any question or query about anything which is troubling you then you let us know. Also if you have any suggestions about any new sustainable product or new technology then also let us know. We appreciate your feedback.

Tools To Tackle the Waste -“Solution To Farm Fires”

According to the United Nations definition, agricultural wastes are waste produced as a result of various agricultural operations. It includes manure, wastes from poultry houses and slaughterhouses; harvest waste; fertilizer run-off from fields; pesticides that enter into water, air or soils; and salt and silt drained from fields.Also, the quantity and composition of agricultural waste are dictated by the geographical and cultural aspects of a country or a region and also the extent of land used for agriculture. Regions into organic farming may produce less of water-polluting chemicals. Animal manure is mostly used up. Highly populated developing regions are bound to produce more of harvest waste due to lack of infrastructure, need for multiple planting of crops and lack of awareness.The economic aspect of waste management is the biggest spoilsport in our land. Pollution of the Northern part of India is mainly due to farm-fires. Farmers in many states don’t have any option but to burn crop waste leading to heavy pollution. It seems that there is no incentive to save this green-gold but to burn it.A Nov. 08 NASA satellite image captured the farm fires in red dots:

Stubble burning is practiced by Indian farmers to easily get rid of the leftover crop following the harvest and ahead of the next sowing season.Several solutions to use crop wastes exist but none of them are actually linked to the starting point. For example, agricultural wastes can be used to make alcohol using a patented technology by an Indian company but neither the company has any enthusiasm to go to the farmer nor does the farmer have economic resources to take his waste to the plants. Some farmers have come out with innovative solutions like watering the fields and then using rotavator, zero drill or happy seeder which can take out the stubble and mix it with soil or seed along with stubble.If the huge quantities of crop waste was somehow quickly taken out compacted and stored manually by farmers away from the fields it would give them time to plan, use and sell this very important resource. Only Monetary gains by selling this waste will motivate farmers not to burn it.Waste coming from agricultural and industrial areas is one of the major environmental problems that leave an adverse effect on the environment. This waste either dumped into the sea or burnt openly in the air which spreading harmful gases and pollution.  Briquette and Baling is the first step towards saving this resource which takes care of convenience and time factor both. Bailing means to compress the waste that occupies excess space and becomes difficult to handle.

Manual version of these machines can be used by anyone, are lightweight and economical and do not require electricity. Waste processed in bales or briquettes need less storage land and are easier to handle. Bales and briquettes can be used for fire or sold off easily giving a source of extra income for rural families especially women.

BRIQUETTING LEVER PRESS

There are numerous sources to produce renewable energy but this the best source to produce energy in an economic and biodegradable way. Briquetting machine gives biomass in a log that is cylindrical in form through the usage of high pressure. Biomass briquettes produce are an alternate source of fuels in comparison to orthodox sources of fossil fuels like oil, natural gas, wood, diesel, etc. In this low energy, fuel can be transformed into high-density fuel at a briquette machine. It is a method of converting waste material into the best product without creating any environmental problem. Bio fuel briquettes are a cheaper source of energy and used in various industries for their different purposes.According to environmentalists, the biofuel generated from agro-waste material is a great source of income for poor farmers in India. Making farmers aware of the existence of such simple machines and the monetary gains from waste is needed.(Author-Darshil is marketing head  SK engineers one of the leading companies in the engineering industry.

Steps taken by Government of India in Promoting Energy Efficient Buildings

Energy Efficiency in Buildings

With the current rate of urbanization and the subsequent increase in energy demand, energy efficiency in buildings has a significant role to play in contributing to energy security in developing countries. Energy consumption patterns can be substantially reduced by energy conserving measures, particularly during the phase of building design. Space heating load can be reduced by about 50%, when economically-viable insulating measures are applied to the building envelopes, i.e. to ceiling and walls. In conventional Indian buildings, energy consumption is 200 kWh per sq. meter. This energy consumption can be reduced to 120 kWh per sq. meter by applications of energy efficient building techniques. Energy efficiency measures for buildings are approaches through which the energy consumption of a building can be reduced while maintaining or improving the level of comfort in the building. They can typically be categorized into:

  • Reducing heating demand;
  • Reducing cooling demand;
  • Reducing the energy requirements for ventilation;
  • Reducing energy use for lighting;
  • Reducing energy used for heating water;
  • Reducing electricity consumption of office equipment and appliances;

Climate and the need to heat or cool a building plays a major role in the design of the external envelope – transparent elements like windows and sunspaces, walls, roofs and floors of a building. By improving the building envelope, passive solar strategies can be developed to improve comfort and reduce energy demands [2]. Mechanical ventilation and air conditioning tend to be electrically-driven and operational throughout the building’s occupied life, which makes them both expensive to operate and, depending on the combined efficiency of national power generation plant, a significant source of greenhouse gas emissions. Removing them from the building design and replacing them with passive designs will have a significant impact over the life of the building. For instance, it is estimated that air-conditioned office buildings consume approximately 250 kWh/m2 per annum, while naturally ventilated office buildings consume 120 kWh/m2 per annum. Similarly, with day lighting reducing the need for artificial lighting, the life-cycle impact will be substantial.

In passive solar building design, windows, walls, and floors are made to collect, store, and distribute solar energy in the form of heat in the winter and reject solar heat in the summer. This is called passive solar design or climatic design because, unlike active solar heating systems, it does not involve the use of mechanical and electrical devices. The key to designing a passive solar building is to best take advantage of the local climate. The elements to be considered include window placement and glazing type, thermal insulation, thermal mass, and shading. Passive solar design techniques can be applied most easily to new buildings, but existing buildings can also be retrofitted.

Energy Conservation Building Code (ECBC)

Building energy codes for new buildings are an important regulatory measure for ushering energy efficiency in the building sector. They are particularly relevant for countries like India where the building stock is rising rapidly. India has begun the gradual introduction of energy efficiency solutions in the building sector. In 2001, the Indian Government introduced the Energy Conservation Act (Bureau of Energy Efficiency, 2011). As an outcome of this act, a first generation building code, the Energy Conservation Building Code (ECBC), came into effect in 2007. Currently, ECBC applies to buildings that have a connected load greater than 100 kW or contract demand greater than 120 kVA (Bureau of Energy Efficiency, 2011). In practice, ECBC requirements are generally only applied to buildings with air-conditioned floor areas of over 1000m2. In principle, the ECBC also applies to large residential complexes, when their connected load or contract demand exceeds the thresholds. The Energy Conservation Act, 2001 empowers the Government of India to prescribe ECBC in India. Bureau of Energy Efficiency (BEE) an autonomous body under Ministry of Power, with support from United States Agency for International Development (USAID) under its Energy Conservation and Commercialization Project (ECO- II Project) launched the first version of ECBC for its implementation in commercial and office buildings on a voluntary basis. As the first stand-alone National Building Energy Efficiency code of India, it sets minimum energy performance requirements of Commercial Buildings and their components. ECBC has been developed by extensive data collection and analysis of different building types, materials, services and usage patterns. Different climatic zones in which building would be constructed were also taken into account. Base case simulation models were then developed for buildings using this background data in these climatic zones. The code is applicable to five major areas of energy consumption in buildings which are:

  • Building Envelope
  • Heating, Ventilation and Air Conditioning
  • Service Water Heating
  • Lighting
  • Electric Power and Motors.

The successful implementation of the code requires development of compliance procedures (compliance forms and development of field-test compliance forms and procedures), in addition to building capacity of architects/designers/builders/contractors and government official in States and Urban and Local Bodies (ULBs). It is also dependent on availability of materials and equipment that meet or exceed performance specifications specified in ECBC. The Bureau of Energy Efficiency (BEE) with the support of USAID ECO- III Project is promoting ECBC awareness and voluntary adoption through training and capacity building programmes, pilot demonstration projects, and identifying steps for compliance check and monitoring of ECBC. ECBC User Guide was developed to support ECBC implementation by providing detailed guidance to the users on how to comply with the Code. Four ECBC tip sheets on Energy Simulation, Building Envelope, Lighting Design and HVAC are also available and provide useful information on Code compliance at the system level and through Whole Building Performance approach that require knowledge of energy simulation to model the proposed building.

The ECBC provides design norms for:

  • Building envelope, including thermal performance requirements for walls, roofs, and windows
  • Lighting system, including daylighting, and lamps and luminaire performance requirements
  • HVAC system, including energy performance of chillers and air distribution systems
  • Electrical system
  • Water heating and pumping systems, including requirements for solar hot-water systems.

The benefits involved for ECBC Compliant Buildings are:

  • Reduce energy consumption
  • Reduce CO2 emissions
  • Lower costs through energy savings
  • Accelerate deployment of energy-efficient technologies.
  • Use of energy efficient equipment.
  • Awareness and importance of Energy Conservation.
  • Better use of Natural Resources

ECBC-Residential

It is of vital importance for India to develop energy-efficiency strategies focused on the residential sector to limit the current trend of unsustainable escalating energy demand. The production of residential building stock in urban areas is shifting quickly toward multi-storey residential buildings from the earlier mode of building individual homes. It is expected that, with the economics of land and the need for cities to be geographically compact, multi-story residential buildings will be the dominant form of meeting the demand for housing in urban areas. This will be the trend for housing for people across the socio-economic spectrum, from low-income to the middle and high-income categories. The initiation of the Energy Conservation Building Code for Residential Buildings (Part I: Building Envelope Design), addresses this category of residential buildings. The Ministry of Power has announced the ECO Niwas Samhita 2018, which is the Energy Conservation Building Code for residential buildings (ECBC-R). The implementation of this code is expected to boost energy efficiency in the residential sector, its occupants, and the larger environment by promoting energy efficiency in the design and construction of homes, apartments, and townships. Implementation of this code is expected to save 125 billion units of electricity by 2030.

The Part-I (Building Envelope Design) of the ECBC has been launched which prescribes minimum standards for building envelope designs with the purpose of designing energy efficient residential buildings. Its early and immediate introduction is to improve the construction and design of new residential building stock, as it is being built currently and in the near future, to significantly curtail the anticipated energy demand for comfort cooling in times to come. This critical investment in envelope construction and design made today will reap benefits of reduced GHG emissions for the lifetime of the 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 [4].

The ECBC-R aims at limiting heat gains/loss from building envelope and for ensuring adequate natural ventilation and day lighting. To limit the heat gain/loss from the building envelope, the code specifies:

  • Maximum value of Residential Envelope Transmittance Value (RETV) for building envelope (except roof) applicable for four climate zones, viz. Composite Climate, Hot-Dry Climate, Warm-humid Climate and Temperate Climate.
  • Maximum value of thermal transmittance of building envelope (except roof) for Cold Climate zone (Uenvelope,cold).
  • Maximum value of thermal transmittance of roof (Uroof) for all climate zones

To ensure adequate natural ventilation, the code specifies.

  • Minimum Openable window-to-floor area ratio (WFRop)
  • To ensure adequate day-lighting, the code specifies.
  • Minimum Visible Light Transmittance (VLT) for the non-opaque building envelope components
  • The code is applicable to all residential use building projects built on plot area = 250 m2. The type of building projects includes, but not limited to:
  • Group housing projects: Building unit or units constructed or to be constructed with one or more floors having more than two dwelling units having common service facilities where land is shared and commonly used by the dwelling units, and the construction is undertaken by one agency.
  • Mixed Land Use Building projects: With buildings partly used for non-residential uses and partly for residential use.
  • Multi-dwelling unit building on residential plots

Conclusion

Buildings are responsible for an enormous amount of global energy use, resource consumption and greenhouse gas emissions. Architectural design based on environmental preservation is the only option for maintaining quality of life and preventing lasting environmental damage. Pollution reduction, waste minimisation and energy conservation can be furthered through environmentally friendly architectural design and construction. There is vast potential of energy saving possible through implementation of ECBC. An urgent need to implement ECBC is required as lots of buildings in the country are yet to come and incorporating ECBC design strategies at planning stage is economical than applying it on old buildings. During the development of ECBC, analysis conducted through energy simulation indicated that ECBC-compliant buildings may use 40 to 60% less energy than similar buildings being designed and constructed at that time. The ECBC 2017 prescribes the energy performance standards for new buildings to be constructed in India. It prescribes standards for current as well as future advancements in building technology to further reduce building energy consumption and promote low-carbon growth by setting parameters for builders, designers, and architects to integrate renewable energy sources in building design with the inclusion of passive design strategies.
