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 Methods – Using 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.

EXCEL COOLCOAT

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

ZERODOR

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.

Conclusion

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.

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.

Conclusion

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.

 

 

solar panel

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.

METHODS OF HARVESTING 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.
