The sustainable buildings will fulfill its destiny as a Green Building until it is constructed with the Green Materials. It is most important criteria one should look before construction of a building. The green building material will enhance the energy efficiency, low carbon emission and gives the occupants the health environment. Studies say that 40% of world raw material is consumed by the construction process.
By using Green building materials, transportation, fabrication, installation and other cost are greatly reduced. The green building materials are composed of renewable resources. Depending on the project one has to select the material carefully. The selection of green material should satisfy following criteria
Energy efficiency
Selecting energy efficient products that are energy star rated, such as Air conditioner, Light bulb, Refrigerators etc. which will greatly save energy consumption.
Resource efficiency
The resources used to build should be recyclable, these product should be manufactured with low carbon emission with minimum waste produced. It should be locally available and durable material.
Cost Efficient
The materials that are used should also be cost efficient. The reduction of cost on buying material indirectly places an impact on the environment while construction such buildings.
The sustainability of the building lies in the materials that are used, so it is very important when choosing material for the Green Buildings that the above criteria are meet.
This multifamily project is not a usual one, Sited at San Jose, Silicon Valley as it is called. This four story building is specially built for low income residents. Designed and developed my FAIA, the building is awarded 145 points by California’s Green Point program. It also gained the Gold ratings in both LEED for New Construction and the LEED for Homes Pilot program.
The building includes all the facilities such as laundry facilities, a community room, and computer room. Completed in June 2007 the building is of 72,000 square feet, which has 35 apartments especially reserved for tenants earning less that half the area median income. The ground floor occupy a beauty salon, it also has play area and a courtyard.
The First community Housing would prefer to locate housing in transit oriented location from which all services and resources are easily accessible. The Goal of the development team was based on this, so they choose a site that is adjacent to light rail. The resident most of them does not own a car or know to drive one, so the earned parking area where constructed with building making it high housing density consisting of 81 units per acre.
The Groceries store located at the ground floor allowed resident to buy things at convenience. The environmental aspect that made this project to win LEED certificate are the photovoltaic array fixed at roof top, high performance insulation in 2x6 exterior wall and also the double-glazed windows. The high efficiency heating system also contributes to this aspect.
The Tenants were allowed to use Energy Star appliances in order to conserve energy.
The 30-Kilowatt photovoltaic system generates energy that was used by building’s common areas and a monitor in the community room. The tenants are billed for their own energy use, ensuring that they have a financial incentive to conserve.
Water conservation features like planting drought tolerant plants, a subsurface irrigation system, dual flush toilets, low flow showerheads and faucets were used. The analysis predicts that it will use 21% of energy and 36% of water when compared with conventional building. The tenants are also very keen in using energy efficient, low pollutant products in their homes.
The project has very good window system in every apartment that allows air and natural light to flow into the building freely. The energy, water efficiency and other conservation method of this build has not only brought up LEED certificate but also made it one of the Top Ten Green Project 2009 by American Institute of Architects.
Located inside the campus of American University of Beirut, The Charles Hostler Student Center covers a area of 204,000 sq. feet that includes swimming pool, three basketball, handball, two squash and a volleyball court. It also has Gym for people to exercise. Apart from these, it has auditorium which could accommodate 280 people, meeting rooms, cafeteria and large underground parking area which can occupy nearly 200 vehicles.
The entire structure is a sustainable, eco-friendly building, which is smoke free and uses energy efficiently. The design is so perfect that it maintains the heat and cool at required level during summer and winter respectively. The use of water and other resource are efficiently designed to meet the Green Building Features.
The roofs are fitted with solar collectors that are used of heating water. It has large rain water harvest system. The other systems that are incorporated are Heat Recovery system, Chilled water generation system. The digital building management system will rank first when compared with other systems; it uses high-tech gadgets to conserve energy as much as possible. Properly designed window provides a good ventilation system and allows natural light to flow into building.
GRE as shortly called is a member owned electric utility cooperative, located at Maple Grove, Minnesota adjacent to Arbor Lake, artificial lake created due to gravel excavation. Designed by architects Perkins + Will and spread about 12.5 acre, the build is a four story office building with concrete frame and glass curtain walls.
The building has many green features that lead it to achieve Top Ten Green Project 2009 by AIA (American Institute of Architects). It uses latest state-of-the-art technology that helped it to reach such status, the low energy HVAC system that features under-floor displacement ventilation and geothermal heating and cooling system that utilizes the lake nearby.
The 160 ft, 200kW wind turbine generates energy that is used by the building apart from the contribution from the solar panels which provides about 15 percent of the building’s total electric need. 40 percent of energy is saved by the daylight design structure of the building.
Great River Energy serves as a model of sustainable practices follows the entire standard that will help the environment. Providing with good view of exterior allows plenty of daylight to enter into building.
Good air and water management system conserves these valuable resources. This in-turn allowed reduces the use of HVAC system to conserve the energy. GRE is a second largest electric wholesale supplier in Minnesota, presently it generates and transmits electricity to more than 620,000 residential, commercial, industrial customers and 28 other distribution cooperatives.
This is the newly constructed congregation center on Dodge Avenue in Evanston. They have committed to do the code of Tikkun Olam i.e. repairing the world. Thus they have come up this new construction which was awarded LEED Platinum certificate recently.
The center in Evanston reused the materials from the previous structure; the front doors of the building were fitted with trees displaced during the milling. The windows are properly placed by which the abundant daylight and fresh air is able to fill the building at the same time it cuts the excess heat and glare. The gardens and children’s playground had gabion rubble walls placed at the edges, which is made from the crushed concrete, brick and limestone from local demolition sites.
The rain water harvesting helps them to save the valuable resource, which will be again reused after filtering process. The storm detention garden saves almost 41% of water use comparable to structure’s use. The various parts of the building uses reclaimed Cypress slats that were used in ceilings and linings. They provide a warm look and act as an acoustics barrier. The HVAC displacement system in prayer hall and other public gathering areas are covered neatly with the reclaimed slats.
The raised podium and step in the sanctuary are using the reclaimed dark walnut from fallen or diseased trees from the Chicago Park District. The entire flooring of the building is concrete that has polished, thus saving money required for new flooring. Cabinets and entire wood work throughout the building are made of pressed sunflower seeds, a rapidly renewable wood like source. The low flow toilets and energy efficient appliances are used to conserve water and energy.
The building has two HVAC systems, one of which is in sanctuary and is the displacement system. This system releases the heat from the bottom rather than from top. By this more energy is saved, because it does not require much electricity to pump heat into the room and it is also less noisy that the traditional HVAC system. This system is only placed in the biggest room, which has the highest visitor traffic. The energy saving payback for this system is five to seven years, which is a rapid progress in the area of heating and ventilation.
The second HVAC is also energy efficient which has a programmable weekly calendar and allows the system to heat rooms and hallways in proper schedules. The schedules were prepared after week long analysis on building’s energy usage by the congregation and architectural team. This schedule decides when and which rooms to be cooled or heated. The building is properly insulated so that even when it is not receiving heating or cooling the temperature is maintained perfectly. The building has only one solar panel installed, due to budget issues, which power’s the building’s Eternal Lights.
Combination of sustainable and eco-friendly products used for the building has not only won LEED Platinum but also been awarded one of the Top Ten Green Projects of 2009 by AIA(American institute of Architects).
The Portola Valley Town Center once Portola Valley School has now become a sustainable eco friendly town center, constructed after salvaging the school building, it now saves energy and other resources.
The building is constructed with various materials that are reused such as reclaimed timber and logs from beaches of North California, beams from school building were reclaimed and used.
Slag mix recovered from old smokestacks is used for concrete in the foundations and walls. This mixture cuts by half the carbon footprint of normal concrete. Window and framing uses the reclaimed wood and plywood certified Douglas-fir. The flooring also uses wood from the fallen tree that were milled and reused.
The lighting system uses energy efficient fluorescent lamps and tubes. The exterior walls are insulated with recycled newsprint and the interiors walls are insulated with ground-up blue jeans.
Natural air flows into building freely by the double hung wooden windows. According U.S. Green Building Council, buildings consume 70% of the nation’s Electricity, 40% of its raw materials and 12 percent of its potable water that generates about 39% of carbon dioxide and producing 30% of wastes.
The water conservation system is the greatest challenge for them to implement, since the area is earthquake region. It was difficult for them to store water above or below the ground. Finally the solution for this issue was brought up by the Public works Director Howard Young, his idea was to send water through a length of 2 foot diameter pipe with a manual cut-off value at one end. The pipe has a capacity of 2,500 gallons of fresh water and it was buried in a small ditch.
70kW Solar panel array is mounted on the roofs of library and community hall. They supply enough electricity to lightings system. It also supplies power to charge the electric vehicles in the parking lot via four plug-in sockets. Awarded one of the Top Ten Green Building of 2009 by AIA, this has it own seismograph which will also be monitored by the computer. With all these features the building is definitely is a friend of environment.
Located in Seattle, Washington the newly constructed building has been rated LEED by USGBC. AIA also chose it as one of the Top Ten Green Project of 2009.
Designed by Weber Thompson, it provides a health and creative environment to the people. Completed in April 2008, this building has 6 stories. It was formerly a light industrial area with parks, multi family residences, offices and industrial buildings. The office space is about 37,000 sq feet on four floors; in the ground floor it has retail and restaurant space with a courtyard for social gathering.
The parking area is underground which has two levels to park cars and bicycles. The office space of this building is occupied by an architectural firm, a real estate firm and a marketing firm.
There will be high level of impact from an office environment than a residential complex. The Terry Thomas was designed to meet all the environmental issues and also enhance the health; productivity of the occupant, the high priority is put upon the energy efficiency of the building so that the future payback will be gained.
The project team started the design after analyzing the need of the occupants which is mainly focused on the daylighting, natural ventilation and improved community meeting place. The team came with the design that prioritized the ventilation, day light and better meeting space.
The new headquarters of International Fund for Animal Welfare has been completed recently with all sustainable strategies implemented in it. DesignLAB modeled and designed this 54,000 square foot structure situated in Yarmouthport, Massachusetts.
This building has also been awarded by U.S Green Building Council – LEED Gold Rating.
The IFAW’s goal and mission is ‘to provide a better world for people and animals’.
This new office facilitates open communication, collaboration and interaction for the people and also it is environmental friendly.
Once a polluted brownfield, it was reclaimed with great effort by DesignLAB and they revitalized it. They achieved the natural habitat by removing contaminants and planted many shrubs, trees, plants and grasses. They also implemented rain water absorbing garden, bio swales, and other permeable landscaping systems to absorb rainwater runoff.
The other water conservation systems implemented inside the building were dual flush toilets, low flow faucets, and a state-of-the-art technology septic system that treats the waste waters. The building used recycled material for its construction like FSC certified wood and recycled structural steel. The high performance glass windows and curtain allows only sufficient amount of light and heat into the building and creates a microclimate inside the building.
The employees of IFAW were put into design workshops that helped to maximize their effectiveness to this environment. The final plan they come up with was to reduce 50% of per person used square footage work space and to increase the collaborative workspace. The workshop also helped the employees to maintain the work space properly and to reduce the use of energy and water as individuals. The proper ventilation system provided fresh air to move in and out of the building freely.
Wondering which is the world’s largest green building? Academy of Sciences Museum is the largest LEED Platinum rated building in the world as well as the most sustainable museum building in the world. It is situated in San Francisco’s Golden Gate Park.
The designers highlighted the re-usage of the materials in the building while applying for the LEED certification. They reused the seahorse railing and the original tiles at the alligator swamp exhibit. The biggest challenge for the designer was to optimize the natural light from the 200 of roof skylights into living rainforest and coral reef.
The designer redesigned the Aquariums which a twice as big as the original and it uses less water because of filtration and recycling systems that purify water piped in from the Pacific Ocean. The nitrate wastes are purified by natural systems, ensuring that aquarium water can be recycled and reused. In order to achieve LEED certification for the Aquariums they used 50% recycled content for the aquarium’s concrete.
The designers call it as the green roof, yes it is green exactly, it is not just a green roof but a living roof. This roof is fully covered with 1.7 million native plants. Architect Renzo Piano designed the roof as homage to the hills of San Francisco. The highlight in this is how the plants are kept without sliding off the hills. Designer Rana Creek along with Mr.Piano used some 50,000 porous, biodegradable trays called BioTray®, which they made from tree sap and coconut husks as containers for the vegetation to keep the little green plants in place.
Apart from the natural habitat created by the roof, it also reduces the Urban Heat Island Effect, and bringing down the building’s temperature almost 10 degrees. The cistern system in the roof will able to capture 90-98 percent of rainwater, which will be about 3.5 million gallons of rainwater per year.
The planetarium, the Africa Hall, Aquariums, and of course the albino crocodile will turn your head towards them apart from the building itself. This building is surely a eco friendly and sustainable.
The world’s first eco-city is coming up in Dongtan, the third largest island in China at the mouth of the Yangtze River. The sustainable city is not just environmental friendly but also socially, economically and culturally.
Designed by ARUP for the Shanghai Industrial Investment Corporate (SIIC), they aim to bring out the city which will consume less energy and emit a low carbon emission.
The 8,600 hectare (86 square kilometer) site is adjacent to wetland of global importance.
The city will comprise two areas one completely urbanized and the other is used for agricultural purpose, thus creating a buffer zone to manage wetland between the city and the ‘natural’ wetland.
This city will produce energy by itself for it consumption from wind, solar, bio-fuel and recycled city waste. The public transport will use the hydrogen fuel cells. The city will have network of cycle and footpaths that will help the city to achieve close to zero vehicle emissions.
Almost all the building in this city is featured to have sustainability, every building are constructed to use less energy as possible and all of them will incorporate daylight control system, which will help to reduce energy consumption. The public spaces were people gather together will have waste management systems that will ensure waste are collected and recycled.
Dongtan site will have a farmland that will use organic methods to grow foods. The city will have green ‘corridors’ of public space ensuring a high quality of life for residents. The city’s design will possibly attract more employment across country and hope that people will choose to live and work there.
Dongtan demonstrates to the world China’s ability to work closely with the environment and has provided a methodology for sustainable communities across China and beyond.
Green buildings will make our earth greener as they use less energy and emit low carbon with its sustainable design. These buildings are built specially to be eco friendly as they also built using recyclable materials. The world has many green buildings constructed with recycled material but Berkeley’s David Brown Center stands out from all. It is the world’s largest recycled building; almost half of its construction is comprised of recycled materials.
This 50,000-square-foot building is designed to be 40 percent more energy efficient as it uses solar energy generated by the photovoltaic cell fitted in its roof and sun-shades on the South façade. Recycled materials can be seen almost at every nook and corner of this four story building. All the furnishings are made from salvaged wood. A mixture of plaster and salvaged soils are used for wall at ground floor reception area.
“Earth Niche” a permanent art installation built using cob, bamboo, salvaged straw earth. This was made by “The Natural Builder” owned by Marisha Farnsworth. Variety of tables and benches in the building are created by Paul Discoe from Live Edge, a company that repurposes lumber from urban street trees that have been cut down due to storm damage, disease, and for other reasons.
The buildings concrete used ¾ of Slag which makes it truly a sustainable building. Slag is an unwanted byproduct of steel-smelting, that turns out to have fortifying properties and more importantly for sustainability in the long run; greatly reduces the CO2 produced in making cement.
The building uses zinc siding that reduces the need for daylighting. The daylighting program includes the automatic controls to balance the daylight when required.
The indoor air quality is maintained with the help of properly designed windows and ventilation systems.
Radiant heating and cooling operate via tubes set into the concrete structural slabs.
The building power consumption is monitored by an interactive real time monitoring system located at lobby. These all aspects of this building are expected to receive a LEED Platinum rating, the highest certification, from the U.S Green Building Council.
Renewable energy source is gaining more importance than the conventional power sources. The world’s largest solar project is now coming at the desert of Los Angeles that can produce more energy than larger nuclear plants.
This plant when completed will produce 1.3 Gig watts of power beating out China’s 1 GW PV plant that was announced to open this December. The plant is a joint venture of Southern California Edison, which serves the locals and Brightsource, the company who will be constructing the power plant.
The power will be generated by focusing light from the area with mirrors onto a tower. Then heat produced by the tower is used to boil water and the steam will turn a turbine, similar to a traditional coal and nuclear power plant.
This project is built with "Solar thermal Mirror" rather than photovoltaic power because it costs cheaper and is simpler to install than the photovoltaic cells. The Solar thermal mirrors have proved to have longer life span. The projects consist of seven towers that can produce 100 to 300 megawatts of electricity. The first one will be 2013 and other tower will be opened later.
China has big plans that will contribute to the environment and our mother earth. Knowing the importance of the sustainable architecture and rising energy issues, china is planning to build some 10,000 green hotels by 2012 reports the publication ChinaCSR.com.
The director of the Trade Service Division of China’s Ministry of Commerce, Mr.Di Jiankai announced the plan Chinese media that 10,000 hotels will be built in four phases in coming year and will be completed by 2012. Initially 1,000 hotels will be built in 2009, 2,000 in 2010 and following year 3,000 hotels and finally 4,000 hotels will be built in 2012.
Every green hotel built will contribute its part for the environment by reducing about 20% of water consumption, 20% of its electrical usage and above all the 45,000 tons of carbon dioxide emissions will be reduced over four years.
The buildings itself will produce its own electricity and they surely have waste management system which will further help in sustainability. Water treatment plants, solar power generators will also be featuring this mega project.
Every building will have clear glasswindows that will allow natural light to flow freely into the buildings thus avoiding use of HVAC system during daytime. Every building will have its own energy monitoring system that will in controlling the energy usage.
The hotel room will have occupant sensor to recognize the person in the room and will turn off the electrical appliances in the absence of occupant. National Standards Commission will review the hotel for every green aspect.
For those in the know, an introduction would be redundant. But for those who aren’t, an introduction is a must – An introduction to GRIHA, or Green Rating for Integrated Habitat Assessment. It is, essentially,
A point based voluntary scoring system to evaluate commercial, residential and institutional buildings on "green scale"
Is based on Indian codes, standards and best practices
Comprises an evaluation panel of eminent professionals
So what’s the big deal about a green building, in the first place? A green building is one that utilizes natural resources to a minimum during its construction and operation. It is evolved through a design process that requires all concerned –the architect and landscape designer and the air conditioning, electrical, plumbing, and energy consultants – to work as a team to address all aspects of building and system planning, design, construction, and operation. They critically evaluate the impacts of each design decision on the environment and arrive at viable solutions to minimize the negative impacts and enhance the positive impacts on the environment.
All right, so what’s the news? The news is that the Union Government of India has, in a landmark decision, made it mandatory for all new buildings of the Public Sector Undertakings and the government to seek new green rating norms in an effort to ensure energy efficiency and tackle climate change threats. Every government building, the law says, must get at least 3-star rating (on a scale of 1-5 stars) under the GRIHA scheme. And why not? The idea is to minimise demand for non-renewable resources and maximise utilization.
Take, for example, the Earth System & Environment Science Engineering Building, a research facility located in the Indian Institute of Technology Campus, Kanpur. The facility, as the name suggests, houses laboratories and other facilities for various disciplines of the environment sciences. The facility is nestled into the existing landscape. In siting the building, the natural course was left undisturbed. The architecture of the building has been designed around the existing vegetation, so as to not disturb the natural surroundings and fully grown.
The facility houses wet labs which are non-air-conditioned spaces on the ground floor and dry labs that are air-conditioned spaces on the first floor. Building design and envelope has been optimised through selection of appropriate wall and roof construction and through adoption of passive design measures after studying the sun path analysis to provide shading devices for windows and roof which would reduce energy demand to condition the spaces. This is probably the only existing building in India with a GRIHA rating of 5 stars, though there are several similar proposed projects, such as the Triburg Headquarters at Udyog Vihar in Gurgaon, Integrated Township in Kanyapur, Asansol, West Bengal, and the Office of Public Works Department, Nashik
Today, glass has an almost indispensable role to play in green architecture. Energy efficient glass is the need of the hour, given its unmatched features of optimum transparency that helps in day lighting of interiors, solar control & thermal insulation which cuts down the relative heat gain, and so on. To elaborate, glass can do the following wonders:
Day Lighting - The use of glass allows the penetration of adequate daylight and facilitates a reduction in power consumption.
Energy Efficiency - High performance glass helps control solar and thermal heat gain, thereby cutting down on air-conditioning expenses.
Recyclability – All architectural glass products are recyclable and qualify as “green” building material.
Recycled Content – The production of glass requires a minimum level of ‘cullet’ or broken glass in the Float Glass manufacturing process thereby by qualifying it as a material with high recycled content.
Acoustic Control – Certain types of architectural glass provide a high degree of acoustic comfort by obstructing the entry of sound from the exteriors of a building.
Blending Interiors with Exteriors – Facades made with reflective glass do not obstruct visibility from the inside.
Self Cleaning – The future belongs to environment friendly self-cleaning glass, a type of architectural glass that keeps itself clean and imparts a brilliant aesthetic effect to buildings.
Green architecture – GRIHA becoming law – Glass. Not just alliteration. A symphony, a necessity, a calling.
To say that Transparence 2009 was a success would be more than an understatement. It would be equivalent to attempting to throw some light on the sun.
28th December 2009, SRM University Campus, G.P Ganesan Auditorium. That’s where it all happened. Transparence blended in with the annual NASA Convention – organized at the same venue on the same day.
In this fourth edition, Transparence proved that it was much more than just an architecture design competition. What started off as a humble attempt to provide students of architecture a platform to showcase their talent, ended up as a lesson in architecture, hard work, innovation, creativity, perseverance and much more for everyone present. At Transparence this year, the students taught more than they learnt. It is well and truly said – Child is the Father of Man.
After a warm welcome and review of the regional rounds through an enjoyable audio-visual, the mentor of the event, Ar. Vidur Bharadwaj delivered an interesting speech. Without much ado, the jury was introduced and the presentations plunged into. Ar. SR Sikka, Ar. I. Zachariah and Ar. Christopher Beninger kindly consented to be the judges.
Eight teams – Two from each of the North, South, West and East regions – competed in the war that was Transparence. The sky was the limit; for a seemingly limitedly-scoped theme (“Ecotel” – an eco-friendly, green hotel building), the students sure came up with some outstanding ideas. Right from forms of nature to fairy tale-like la la lands, they had it all.
The winning concept was “Evolve with nature; nature’s impression in design; a design inspired by elements of nature”. The award was bagged by a team of three enthusiastic youngsters from Sir JJ College of Architecture, Mumbai. The runners up were the IIT Kharagpur team, which used water as the primary element of design conceptualization, mostly in terms of rainwater harvesting and optimum utilization of this life-giving substance. The first runner-up prize was bagged jointly by teams from IIT Roorkee and SAP Chennai, who worked on the concepts of “Bubbles” and “Eco-Village” respectively.
Renowned Architect Karan Grover stood out in the event through his brilliant presentation on Green Architecture, which comprised not just drab powerpoint slides but several videos, images and relevant examples that drove home every point he made.
Saint-Gobain Glass also took this opportunity to launch SGG Envision, its latest offering in architectural glass. Ar. CN Raghavendran did the launch honours.
The end of Transparence 2009 marked the beginning of Transparence 2010, the theme for which was duly unveiled and revealed to be “An International Convention Centre”, and Ar. Niteen Parulekar was proclaimed the mentor.
All in all, the Grand Finale of Transparence 2009 was a truly memorable affair.
After the Union Government, now the state governments, too, are making green buildings the law. Now the Maharashtra State Government has decided to make available incentives in the form of rationalization in property tax /electricity tariff and reduction in State taxes including VAT and Octroi on buildings adhering to green technology norms.
To achieve this, Maharashtra Government proposes to amend the Development Control Rules for the introduction of green building regulations initially in Mumbai Metropolitan City and later in tier II cities of the State. Under the proposed regulations, it will be mandatory for new buildings to use green technologies for recycling dry waste and drainage water, vermin-culture for treatment of wet waste,solarenergy and above all rainwater harvesting. The latest move drew an overwhelming response from various quarters including builders because it has come at a time when the City is reeling under acute water shortage and is destined to face power deficit in the near future.
Maharashtra is not the first state to take this desirable step. Such initiatives have already been initiated in several States including Delhi, West Bengal, Karnataka, Kerala and Rajasthan. But in the realty sector, Maharashtra will be the first to put such incentives on its radar in a more regulatory form.
According to reports emanating from the State, the Housing, Urban Development and Environment Department will hold a meeting very shortly to look into the various aspects of green building regulations and the implementation procedures in Mumbai and later in tier II cities. Brihan Mumbai Municipal Corporation through a notification has already asked developers of new buildings to go for rainwater harvesting system. The objective of the proposed green building regulations is to make all efforts to minimize the impact of climate change. At the same time doing so should not affect the Government’s target of affordable housing in Mumbai and other parts of the State.
All said and done, a step like this taken by the governments of these states is one in the right direction.
Leadership in Energy and Environmental Design (LEED) is an internationally recognized green building certification system, providing third-party verification that a building or community was designed and built using strategies aimed at improving performance across all the metrics that matter most: energy savings, water efficiency, CO2 emissions reduction, improved indoor environmental quality, and stewardship of resources and sensitivity to their impacts.
Developed by the U.S. Green Building Council (USGBC), LEED provides building owners and operators a concise framework for identifying and implementing practical and measurable green building design, construction, operations and maintenance solutions.
LEED is flexible enough to apply to all building types – commercial as well as residential. It works throughout the building lifecycle – design and construction, operations and maintenance, tenant fit out, and significant retrofit. And LEED for Neighborhood Development extends the benefits of LEED beyond the building footprint into the neighborhood it serves.
LEED was created to accomplish the following:
• Define "green building" by establishing a common standard of measurement
• Promote integrated, whole-building design practices
• Recognize environmental leadership in the building industry
• Stimulate green competition
• Raise consumer awareness of green building benefits
• Transform the building market
LEED is a voluntary certification program that can be applied to any building type and any building lifecycle phase. It promotes a whole-building approach to sustainability by recognizing performance in key areas:
1. Sustainable Sites
Choosing a building's site and managing that site during construction are important considerations for a project’s sustainability. The Sustainable Sites category discourages development on previously undeveloped land; minimizes a building's impact on ecosystems and waterways; encourages regionally appropriate landscaping; rewards smart transportation choices; controls storm water runoff; and reduces erosion, light pollution, heat island effect and construction-related pollution.
2. Water Efficiency
Buildings are major users of our potable water supply. The goal of the Water Efficiency credit category is to encourage smarter use of water, inside and out. Water reduction is typically achieved through more efficient appliances, fixtures and fittings inside and water-wise landscaping outside.
3. Energy & Atmosphere
According to the U.S. Department of Energy, buildings use 39% of the energy and 74% of the electricity produced each year in the United States. The Energy & Atmosphere category encourages a wide variety of energy strategies: commissioning; energy use monitoring; efficient design and construction; efficient appliances, systems and lighting; the use of renewable and clean sources of energy, generated on-site or off-site; and other innovative strategies.
4. Materials & Resources
During both the construction and operations phases, buildings generate a lot of waste and use a lot of materials and resources. This credit category encourages the selection of sustainably grown, harvested, produced and transported products and materials. It promotes the reduction of waste as well as reuse and recycling, and it takes into account the reduction of waste at a product’s source.
5. Indoor Environmental Quality
The U.S. Environmental Protection Agency estimates that Americans spend about 90% of their time indoors, where the air quality can be significantly worse than outside. The Indoor Environmental Quality credit category promotes strategies that can improve indoor air as well as providing access to natural daylight and views and improving acoustics.
6. Locations & Linkages
The LEED for Homes rating system recognizes that much of a home's impact on the environment comes from where it is located and how it fits into its community. The Locations & Linkages credits encourage homes being built away from environmentally sensitive places and instead being built in infill, previously developed and other preferable sites. It rewards homes that are built near already-existing infrastructure, community resources and transit, and it encourages access to open space for walking, physical activity and time spent outdoors.
7. Awareness & Education
The LEED for Homes rating system acknowledges that a green home is only truly green if the people who live in it use the green features to maximum effect. The Awareness & Education credits encourage home builders and real estate professionals to provide homeowners, tenants and building managers with the education and tools they need to understand what makes their home green and how to make the most of those features.
8. Innovation in Design
The Innovation in Design credit category provides bonus points for projects that use new and innovative technologies and strategies to improve a building’s performance well beyond what is required by other LEED credits or in green building considerations that are not specifically addressed elsewhere in LEED. This credit category also rewards projects for including a LEED Accredited Professional on the team to ensure a holistic, integrated approach to the design and construction phase.
9. Regional Priority
USGBC’s regional councils, chapters and affiliates have identified the environmental concerns that are locally most important for every region of the country, and six LEED credits that address those local priorities were selected for each region. A project that earns a regional priority credit will earn one bonus point in addition to any points awarded for that credit. Up to four extra points can be earned in this way.
The Bureau of Energy Efficiency (BEE) is an agency of the Government of India, under the Ministry of Power, created on 1st March 2002 under the provisions of the nation's 2001 Energy Conservation Act. The agency's function is to develop programs which will increase the conservation and efficient use of energy in India. The government has proposed to make it mandatory for all appliances in India to have ratings by the BEE starting January 2010.
The prime aim of BEE is to reduce energy consumption in the country and promote energy efficiency through various strategies and policies. The Bureau of Energy Efficiency also aims at organizing the energy efficiency services available and to develop mechanisms to offer these services. There are a number of organizations that are involved in the movement of energy conservation, and providing leadership to these movements is also under the agenda of BEE.
The BEE in India also has the responsibility of monitoring the effects of energy efficiency programs in different sectors of the country. It is also involved in the process of implementing the Energy Conservation Act and to design programs according to this Act. For this purpose, BEE encourages the private sector to work jointly with the public sector. It also ensures the delivery of different programs related to energy efficiency. For implementing all these programs, the Bureau takes help from different public as well as private organizations of the country.

Awards by BEE
NATIONAL ENERGY CONSERVATION AWARDS are given to selected Industrial units who have made systematic and serious attempts for efficient utilization and conservation of energy. Bureau of Energy Efficiency coordinates the Energy Conservation Awards scheme of the Ministry of Power. The Awards were given away for the first time in December 14, 1991.
The BEE Star Energy Efficiency Labels have been created to standardize the energy efficiency ratings of different electrical appliances and indicate energy consumption under standard test conditions. Thus we can also conserve the cost of electricity by switching to electrical appliances with BEE (Bureau of Energy Efficiency) label.
BEE Star Labels
These labels indicate the energy efficiency levels through the number of Stars highlighted in colour on the label. The BEE Star Labels include a Star Rating System that ranges from One Star (least energy efficient, thus least money saved) to Five Stars (most energy efficient, thus most money saved).
We can reduce your electricity bills and help India to increase the availability of electricity for more people, simply by buying Refrigerators, ACs & Tube lights that bear BEE’s Star-Rated Energy Efficiency Labels.
BEE in Automobiles
The Indian Bureau of Energy Efficiency (BEE) recently proposed rating automobiles in the country on the basis of their energy efficiency. The proposal suggests charging a registration fee of Rs 2,000 per vehicle to rate the fuel efficiency of its engine and another Rs 1,000 to assess its energy consumption. Vehicles with the highest efficiency will get a 5-star rating and those with the lowest a single-star rating. The BEE plans to make this procedure mandatory after a few years.
Scheme for star rating office buildings
Energy audit studies in buildings have shown large potential for energy savings both in government and commercial office buildings. Study of the available data has shown that there is an urgent need for improved energy efficiency of buildings.
National commercial energy benchmarking initiatives was taken up with a goal to establish a framework to standardize energy data collection, baseline setting for “typical” commercial buildings, energy performance target setting and monitoring and use the information to improve energy efficiency in buildings. This information can help the user and other stakeholders to evaluate building energy efficiency and track improvements compared to other buildings and recognize the top performers.
The Star Rating Program for buildings would create a demand in the market for energy efficient buildings based on actual performance of the building in terms of specific energy use. This programme would rate office buildings on a 1-5 star scale with 5 star labelled building being the most efficient.
Five categories of buildings – Office buildings, hotels, hospitals, retail malls, and IT parks in five climate zones in the country have been identified for this programme.
Initially, the programme targets the following 3 climatic zones for air-conditioned and non-air conditioned office buildings.
a) warm and humid
b) composite
c) Hot and Dry
It will be subsequently extended to other climatic zones.
To apply for rating of office buildings, a standardized format is developed for collection of actual energy consumption; data required includes building’s built up area, conditioned and non-conditioned area, type of building in a day, climatic zone in which buildings is located, and other related information of the facility.
The technical committee constituted for Energy Base lining and benchmarking of commercial buildings chaired by Director General, Bureau of Energy Efficiency shall be the technical committee for the scheme.
The global manufacturer of building materials Saint-Gobain recently built the world’s first low energy playhouse in the centre of Copenhagen during the UN climate change conference. The house is beautifully and boldly designed by the famous architects at Arkitektfirmaet C.F. Møller.
Saint-Gobain is present in Copenhagen during the UN climate change conference – in a very special way. The world’s first low energy playhouse which is large enough to serve as an annexe in private gardens or yards was proudly built by Saint Gobain. This is happened in the very centre of Copenhagen, at the Højbro Plads square, just opposite the Danish parliament December 7-18, 2009. And it is as great a photo opportunity.
The new, unique concept, “Playhouse” has been developed by six Danish Saint-Gobain companies and the renowned architects at Arkitektfirmaet C.F. Møller. The house, which was approximately 3 x 4 meters, has 40 cm thick walls stuffed with highly effective Isover insulation and three large 3-layer windows panes from Scanglas – one of them in the roof. Inside, the house has been lined with impact resistant plasterboards from Gyproc and acoustic boards from Gyproc and Ecophon that secure a comfortable sound environment. The play house is full of happy kids!
The house has been so perfectly insulated that in principle one could heat with a handful of candle sticks. Simultaneously, the insulation and the windows prevent the house from being over heated during summer. The panes have different coatings depending on their direction – north, south and upwards. The diamond-shape of the house has a beautiful architectural effect, but it also prevents the hot summer sun to heat the house through the south window.
This is a playhouse, but big enough to function as a small guesthouse. On some days the house functions as a studio for the nationwide radio channel NOVA fm broadcasting live climate quiz and interviewing politicians and experts about the conference and CO2-reductions.
The house was a part of Saint-Gobain’s new, global “Habitat strategy” which among other things proclaims that the company is going to be a world leader in supplying materials to sustainable buildings. At the same time it is ushering a new and more close corporation among Danish Saint-Gobain companies.
The six Danish companies involved in the Playhouse project are: Isover (insulation), Scanglas (window panes), Saint-Gobain Glass (pane coatings), Gyproc (plasterboards), Ecophon (acoustic wall absorbents) and Vetrotech (fire protected glass).
Saint-Gobain Glass India (SGGI) has always championed the cause of not just socially responsible but also of environment-friendly business practices. In recent times, this fact has been reinforced by Saint-Gobain receiving 2 awards from Confederation of Indian Industries (CII):
National Award for Water Management as an Excellent Water-Efficient Unit•
National Award for Innovative Case Study for Water Management
Both these awards were received for the Saint-Gobain Glass India World Glass Complex located at Sriperumbudur, Tamil Nadu. The sprawling 177-acre facility showcases the Company’s commitment to investing in state of the art, world class manufacturing facilities whose hallmark is efficient as well as effective use of natural resources and energy. Indeed, sustainability and eco-friendliness is truly the company’s motto, given that their portfolio of glass products also caters to the needs of green architecture.
The Effort
The Integrated Quality, Environment, Occupational Health & Safety Policy of SGGI clearly brings out the company’s single-minded commitment to protecting the environment through a Consistent Monitoring, Continual Improvement and Environmental Risk Management process. The Integrated Management System certification obtained under QMS, EMS and OHSAS enshrines the above policy.
The following diagram illustrates the Water Management approach at SGGI:
The monitoring & reviewing of the Water Management process at SGGI is performed at all levels, right from the Shift Engineer to the Corporate Delegation.
The Results
All this effort has yielded significant and measurable result. The per capita consumption of water has come down from 140 litres/day in 2006-’07 to 85 litres/day in 2008-’09. Also on the decline is the generation of waste water - while 2006-’07 saw 92,652 kilolitres/day of waste water, 83,371 was the corresponding figure for 2008-’09.
Zero Water Discharge concepts is being applied whereby water is recycled and reused to the extent possible, beyond which it is put to non-industrial use as well. Over the 10 years of its existence, the SGGI World Glass Complex has nurtured 15,000 trees, 12 acres of lawn and 5 acres of foliage.
Awareness and consciousness towards the environment has also actively been spread by company representatives throughout the society; both to families, local communities as well as schoolchildren.
Environment, Health and Safety Initiatives have been taken for the local community as well. De-silting of local lakes, building of water channels and provision of water-efficient sanitation facilities are among these initiatives.
All in all, Water Management is a step in the right direction; a truly commendable and desirable effort on the part of Saint-Gobain Glass India.
GRIHA, an acronym for Green Rating for Integrated Habitat Assessment, is the National Rating System of India. GRIHA is a Sanskrit word meaning – ‘Abode’. Human Habitats (Buildings) interact with the environment in various ways. Throughout their life cycles, from construction to operation and then demolition, they consume resources in the form of energy, water, materials, etc. and emit wastes either directly in the form of municipal wastes or indirectly as emissions from electricity generation. GRIHA attempts to minimize a building’s resource consumption, waste generation, and overall ecological impact to within certain nationally acceptable limits / benchmarks.
GRIHA attempts to quantify aspects such as energy consumption, waste generation, renewable energy adoption, etc. so as to manage, control and reduce the same to the best possible extent.
GRIHA is a rating tool that helps people assess the performance of their building against certain nationally acceptable benchmarks. It will evaluate the environmental performance of a building holistically over its entire life cycle, thereby providing a definitive standard for what constitutes a ‘green building’. The rating system, based on accepted energy and environmental principles, will seek to strike a balance between the established practices and emerging concepts, both national and international. The guidelines/criteria appraisal may be revised every three years to take into account the latest scientific developments during this period.
The Context and Development
Internationally, voluntary building rating systems have been instrumental in raising awareness and popularizing green design. However, most of the rating systems devised have been tailored to suit the building industry of the country where they were developed.
TERI took the responsibility of popularizing green building by developing a tool for measuring and rating a building's environmental performance in the context of India's varied climate and building practices.
This tool has been adopted by the Ministry of New and Renewable Energy. This tool, by its qualitative and quantitative assessment criteria, is able to ‘rate’ a building on the degree of its ‘greenness’. The rating would be applied to new building stock of varied functions – commercial, institutional, and residential.
The challenges
The Indian building industry is highly de-centralized with people and/ or groups engaged in design, construction, equipment provision, installation, and renovation working together. Each group may be organized to some extent, but there is limited interaction among the groups, thus disabling the integrated green design and application process.
Hence, it is very important to define and quantify sustainable building practices and their benefits. It is also important to separate the role of different participants in ensuring that the building consumes minimal resources over its entire life cycle and leaves behind a minimal environmental footprint.
Basic features
The system has been developed to help ‘design and evaluate’ new buildings (buildings that are still at the inception stages). A building is assessed based on its predicted performance over its entire life cycle – inception through operation. The stages of the life cycle that have been identified for evaluation are:
Pre-construction stage (intra- and inter-site issues like proximity to public transport, type of soil, kind of land, where the property is located, the flora and fauna on the land before construction activity starts, the natural landscape and land features)
Building planning and construction stages (issues of resource conservation and reduction in resource demand, resource utilization efficiency, resource recovery and reuse, and provisions for occupant health and well being). The prime resources that are considered in this section are land, water, energy, air, and green cover.
Building operation and maintenance stage (issues of operation and maintenance of building systems and processes, monitoring and recording of energy consumption, and occupant health and well being, and also issues that affect the global and local environment.
The benefits
On a broader scale, this system, along with the activities and processes that lead up to it, will benefit the community at large with the improvement in the environment by reducing GHG (greenhouse gas) emissions, reducing energy consumption and the stress on natural resources.
Some of the benefits of a green design to a building owner, user, and the society as a whole are as follows:
Reduced energy consumption without sacrificing the comfort levels
Reduced destruction of natural areas, habitats, and biodiversity, and reduced soil loss from erosion etc.
Reduced air and water pollution (with direct health benefits)
Reduced water consumption
Limited waste generation due to recycling and reuse
Reduced pollution loads
Increased user productivity
Enhanced image and marketability
Rating System

GRIHA has a 100 point system consisting of some core points, which are mandatory to be met while the rest are optional points, which can be earned by complying with the commitment of the criterion for which the point is allocated. Different levels of certification (one star to five stars) are awarded based on the number of points earned. The minimum points required for certification is 50. Buildings scoring 50 to 60 points, 61 to 70 points, 71 to 80 points, and 81 to 90 points will get one star, ‘two stars’, ‘three stars’ and ‘four stars’ respectively. A building scoring 91 to 100 points will get the maximum rating viz. five stars.
LEED points are awarded on a 100-point scale, and credits are weighted to reflect their potential environmental impacts. Additionally, 10 bonus credits are available, four of which address regionally specific environmental issues. A project must satisfy all prerequisites and earn a minimum number of points to be certified.
In LEED 2009 there are 100 possible base points plus an additional 6 points for Innovation in Design and 4 points for Regional Priority. Buildings can qualify for four levels of certification:

The Energy Conservation Building Code (ECBC), launched on 28 June 2007, is a document that specifies the energy performance requirements for all commercial buildings that are to be constructed in India. The code is mandatory for commercial buildings or building complexes that have a connected load of 500 kW or greater or a contract demand of 600 KVA or greater. The code is also applicable to all buildings with a conditioned floor area of 1,000 m2 (10,000 ft2) or greater.
The ECBC has been developed by India’s Bureau of Energy Efficiency, and is mandated by the Energy Conservation Act, 2001, passed by the Indian Parliament in September 2001.
ECBC is a set minimum energy efficiency standards for design and construction. ECBC encourage energy efficient design or retrofit of buildings so that it does not constrain the building function, comfort, health, or the productivity of the occupants and also have appropriate regard for economic considerations (life cycle costs i.e. construction + energy costs are minimized).
BEE would take suitable steps to prescribe guidelines for energy conservation building codes. Central Government can prescribe energy conservation building codes, and direct owners/occupiers to comply with them. State Government can modify the code in response to local climate conditions. ECBC provides a platform for the Broad stakeholders such as Building Industry, manufactures, professionals, Government Agencies etc to participate. ECBC addresses local design conditions and construction practices. It also emphasis on maximizing building envelope benefits – to encourage better designs.
ECBC defines the norms of energy requirement per sq. metre of area and takes into consideration the climatic region of the country, where the building is located. Norms have been developed to cater to 5 different climatic zones in India such as composite, hot and dry, warm and humid, moderate and cold.
The energy from the rays of the sun that can be converted to usable heat and electricity is referred to as solar energy. Solar energy is power derived from the rays of the sun. It is considered to be one, if not the most, environmentally friendly source of energy that can be used on earth. This solar energy can be converted into some other forms of energy and can be used for various applications. Solar panels harvest sunlight and actively convert it to electricity.
Using solar panels is a great way to generate clean and renewable electricity from solar energy to power remote appliances, or even the average home. Having a solar panel energy system can be a great thing because it will allow you to save money on your energy costs. It can be very expensive to heat or cool your house so having a way to use the sun's energy can be very beneficial. Most of the things about using solar energy are positive except in some cases the cost can be expensive. Solar energy is used to reduce global warming at the same time saves lots of money.
Residential solar panels
Residential solar panels continue to be one of the largest trends in green building and energy conservation. Solar panels are quickly becoming one of the most affordable ways to lower utility costs for the homeowner.
Homes connected to the utility electrical grid are known as grid-tied homes or on-the-grid systems, while off-grid homes rely on batteries and need to be a safe distance from power lines. Most homeowners choose to work on the grid due to the added security from the utility company.
Residential solar energy systems still function on cloudy days by drawing upon backup electricity from the utility company (for on-the-grid systems), and the same is true during night hours. For off-the-grid systems, the panels are usually connected to a battery storage system as the backup power source and will extract energy if there is a deficiency that day.
Solar Cells
Solar panels are made up of number of solar cells. Solar Cells, or photovoltaic cells, are arranged in a grid-like pattern on the surface of the solar panel. These solar voltaic cells collect sunlight during the daylight hours and covert it into electricity. Sometimes the term solar cell is reserved for devices intended specifically to capture energy from sunlight, while the term photovoltaic cell is used when the light source is unspecified. The field of research related to solar cells is known as photo voltaic.
Solar electric panels contain many photovoltaic cells electrically connected and packaged behind glass for mechanical protection and electrical insulation. The modules are usually connected together in an array and with other components such as a mounting frame and an electrical inverter (for on grid) or a charge controller and batteries (for off grid).
In addition to solar panels, a photovoltaic (PV) system requires a mounting structure to tilt panels toward the sun, an inverter to convert panel-generated direct current (DC) into appliance-friendly alternating current (AC), battery storage to compensate for unfavourable weather conditions, and a charge controller to regulate battery operation.
Two Forms of solar cells
There are two main forms of solar cells in existence today, and these are; "solar electricity panels" and "solar hot water panels". The two different technologies allow us to either generate electricity for our homes or to heat the water we use.
The combination of a solar hot water panel with other renewable energy technologies, such as solar panels, or a home wind turbine can work quite well together in providing a source of cheap, clean, and renewable energy for our homes.
Solar Panel
Solar panels consist of modules that contain solar cells and convert sunlight into direct current (DC) electricity. An inverter within the panel converts the DC power into alternating current (AC) electricity that is used to heat and cool the home, and also operate any home appliance or device.
Solar Panels are a form of active solar power. The term solar panel is used to describe two completely different technologies, both of which generate energy from sunlight, and both of which are packaged in the form of panels:
a photovoltaic module is used to generate electricity
a solar thermal collector is used to generate heat (generally hot water)
Solar panels are typically constructed with crystalline silicon, which is used in other industries (such as the microprocessor industry), and the more expensive gallium arsenide, which is produced exclusively for use in photovoltaic (solar) cells.
Other, more efficient solar panels are assembled by depositing amorphous silicon alloy in a continuous roll-to-roll process. The solar cells created from this process are called Amorphous Silicon Solar Cells, or A-si. Solar Panels constructed using amorphous silicon technology is more durable, efficient, and thinner than their crystalline counterparts
For very important solar projects, such as space probes that have to rely on solar energy, very-high efficiency solar cells are constructed from gallium arsenide by a process called molecular beam epitaxy. Solar cells constructed by this process have several p-n junction diodes, each designed to be maximally efficient at absorbing a given part of the solar spectrum. These solar panels are much more efficient than conventional types, but the process and materials involved make them far too expensive for everyday applications.
The newest solar panels function on the molecular or quantum level, and represent an exciting new technology coming into play. These solar panels are created by implanting carbon nanotubes or quantum dots into a treated plastic. Unlike silicon-based solar panels, these solar panels do not have to be constructed in a clean room, and therefore production costs are somewhat diminished.
Power production
In direct sunlight at the surface of the equator, a maximally efficient photovoltaic cell about 1/5m in diameter creates a current of approximately 2 amps at 2 volts, however, due to the Earth's atmospheric interference, terran solar panels will never perform as well as solar panels exposed directly to the sun's rays.
Solar hot water panel
Solar hot water panels are a means to harness the sun's energy in a unique way. Like traditional solar panels, solar hot water panels are placed in direct sunlight, oftentimes arrayed on rooftops. A solar hot water array often referred to as a solar hot water heater, uses the energy from the sun to heat a fluid, which is in turn used to move heat generated in the array to a heat storage vessel. The process starts by heating a body of sanitized water and storing it in a hot water cylinder. Next, solar hot water panels would be installed on the rooftop, each with a darkly-coated absorber plate complete with water circulation tubes.
The tubes carry the heated water from the solar water heater to a place where it can be used or stored. A heat exchanger released heat and circulates the cooled water back to the solar hot water array to be reheated. This cycle of heating, energy utilization, and cooling is begun anew with each sunrise and lasts throughout the day for the effective life of the solar hot water heater. These arrays are especially useful for businesses that utilize large quantities of hot water, such as the pictured Laundromat.
Solar hot water heaters are composed of a several hot water panel units, and can be fully automated systems.
Being a heavy user of fossil fuels, China contributes greatly to pollution and ozone layer destruction. 70% of China’s needs are met by fossil fuels; however, in recent times the country has taken some steps towards environment preservation by relying on wind and solar power as sources of energy.
A vast fan-shaped roof of an 800,000 square-foot facility located in China has officially taken the title of “largest solar-powered office building in the world“. It is situated in Dezhou, Shangdong Province in northwest China. This world's largest solar energy office building was opened on November 27, 2009. Its semi-circular, dial-shaped roofsare covered with solar panels. The building covers an area of 75,000-square-meter. The office building is modelled after the sun dial structure.
The design of the new building is based on the sun dial and “underlines the urgency of seeking renewable energy sources to replace fossil fuels.” Conservation of steel was carefully considered through construction and the building is primarily white, which both symbolizes clean energy and reflects solar radiation back to the atmosphere rather than absorbing it as unwanted heat.
The building provides many services such as space for exhibition centres, scientific research facilities, meeting and training facilities and a sustainable hotel. This building is named as the Sun and the Moon Altar micro-row buildings. The architecture included the Chinese characters for sun and moon. It'll be a showcase of solar design, solar desalination, and, of course, about 50,000 square-feet of solar panels on the exterior.
Aside from the obvious sustainable nature of the solarpanel – clad exterior, other green features include advanced roof and wall insulation practices resulting in an energy savings of 30% more than the national standard. In addition, the external part of the construction makes use of about 1 percent of the amount of steel that was used to build the famous Olympic Stadium, Bird's Nest.
This centrepiece of the $22 billion development–the world’s first sustainable city–will be a 1.4 million square-foot solar building that is energy positive; that is, it will actually produce more power than it needs. This energy efficient building will procure 95% of its energy needs from alternative energy sources. This building also has the facilities of solar hot water and a solar energy theme park.
The building's ground-breaking solar energy and power-saving technologies, some of which have already been patented, include a number of technical advances that will push forward the mass applicationof solar energy. Its extraordinary profile and cutting edge, symbolic design has already made it a local as well a national and international landmark.
Renewable Energy is now playing a vital role in providing clean energy solutions. Being a tropical country, India is blessed with an enormous amount of solar energy, both in terms of heat and light, throughout the year. The Government of India has already started focussing its attention towards the development and deployment of renewable energy systems and devices including solar energy in the country through the Ministry of New and Renewable Energy.
Solar energy in broad terms can be harnessed through two routes: Solar Thermal and Solar Photovoltaic. The Solar Thermalroute has applications such as water heating, air heating, cooking, drying of agricultural and food products, distillation of water, water purification, detoxification of wastes, cooling and refrigeration, process heat for industry, steam generation for cooking and electricity generation.
Through the Solar Photovoltaic route, solar lights, solar pumps, solar road studs, solar blinkers, solar power plants for villages, telecommunication systems, energy for computers, solar power for schools and hostels, battery charging, railway signalling etc can be powered.
The designing of energy efficient buildings based on solar passive architecture along with energy efficiency measures is also an upcoming activity. Most of these systems & devices have been developed in India through Research & Development and demonstration programmes.
Solar Energy Conclave 2010
Recently, Ministry of New and Renewable Energy (MNRE) along with Federation of Indian Chambers of Commerce & Industry (FICCI) organized a 'Solar Energy Conclave 2010' which provided a common platform to share the experience of various stake-holders including the NRI's in promotion of Solar Energy in India and making the National Solar Mission targets, a reality.
The main objective of the event was to showcase the opportunities and the potential of solar energy development in the country. With the launching of National Solar Mission, India was set to harness its huge solar potential. At that juncture the conclave provided a common ground for Non-Resident Indians (NRI's) and Indian stakeholders to join hands for making the National Solar Mission a success and facilitate further expansion.
National Solar Mission inaugurated by PM Dr. Manmohan Singh
India’s Prime Minster Dr. Manmohan Singh inaugurated the Jawaharlal Nehru National Solar Mission on 11th January 2010 at Vigyan Bhawan, New Delhi at the Solar Energy Conclave 2010. The Mission was launched under the brand name ‘Solar India’. While launching he said its success could transform India’s energy prospects.
Speaking on the occasion, the Prime Minister said that this National Solar Mission has the pride of place in India’s National Action Plan on Climate Change. Its success has the potential of transforming India’s energy prospects, and contributing to national as well as global efforts to combat climate change. This Mission is one of the major priorities of the second term of our government. He congratulate Dr. Abdullah and the other colleagues particularly Shri Shyam Saran, for the work they have done in bringing this to fruition.
He said that the target of 20,000 MW of solar generating capacity by the end of the 13th Five Year Plan is an ambitious target but he believes that the target is doable and that everyone should work single-mindedly to achieve it as priority national endeavour.
The carefully crafted regulatory and incentive framework that has been unveiled today has several innovative features. We expect that it will lead to a rapid scale up of capacity. This will encourage technological innovation and generate economies of scale, thereby leading to a steady lowering of costs. Once parity with conventional power tariff is achieved, there will be no technological or economic constraint to the rapid and large-scale expansion of solar power thereafter, he said.
He hoped that the mission would also establish India as a global leader in solar energy, not just in power generation but in manufacturing and technology.
He also said-It was the vision of Pandit Jawaharlal Nehru that enabled India to create world-class scientific and technological capacities in the field of atomic energy and space sectors. Solar energy can also be the next scientific and technological frontier in India after Atomic Energy, Space and Information Technology.
“If the ambitious roll out of the Mission is to become a reality, we will have to create many ‘Solar Valleys’ on the lines of the Silicon Valleys that are spurring our IT industry across the four corners of our country. These valleys will become hubs for solar science, engineering and research, fabrication and manufacturing,” he added. He urged industry to see the mission as a huge business opportunity.
In his concluding remarks he said that “The Sun has long been recognized as a primal source of all energy on earth. In an ancient civilization like India, the Sun has been worshipped as the God who bestows life and sustains it. The bounty of the Sun is truly inexhaustible, renewable and free. It is to this source of energy that humankind must turn to meet the twin challenge of energy security and climate change. I wish the Jawaharlal Nehru Solar Mission every success.”
Dr. Farooq Abdullah on the Solar Energy Conclave 2010
Dr. Farooq Abdullah said India plans to install 20 million solar lights and 20 million square metres of solar panel to generate 20,000 MW by 2022 as part of the Jawaharlal Nehru National Solar Mission, Union Minister for New and Renewable Energy.
Farooq Abdullah, in his note address “By 2022, we aim to install 20 million square metres of solar thermal collectors and save 7,500 MW power generation capacity,” he said at the launch of the mission here. “We want 20 million solar lights to be installed by 2022, which would result in a saving of one billion litres of kerosene every year.”
“In the next three years, India plans to add 1,300 MW of solar power, of which 1,100 MW will be grid-connected and 200 MW will be off-grid. This is our first benchmark. If we achieve this, achieving the remaining target will not be impossible. A huge constraint in the commercial use of solar energy has been its cost. Today, the initial cost of solar energy is very high, especially for grid power generation. We aim to bring down the cost as quickly as possible,” Dr. Abdullah added.

Saint-Gobain Abrasives aims to be a global steward of Sustainable Development. Saint-Gobain Abrasives recognize the importance of protecting the environment in the communities they live and work and encourage all employees to act accordingly to reduce the carbon footprint.
Recently in North America, Saint-Gobain Abrasives has inaugurated the “Green Tag” program to promote the Group’s environmental commitment. The Goal of this “Green Tag” is simple. Any environmentally-friendly product, process or tool may be identified by a “Green Tag” label, indicating its ecological benefits: an effective way to show customers the environmental progress made by Saint-Gobain.
This recent implementation of a new program, GreenTag, will further develop the evaluation of policies, procedures and improvements in operations, through products, purchasing and production at Saint-Gobain. How the company presents its corporate identity and ongoing actions of eco-consciousness sends a strong message on its commitment to safe practices and the dependability of their brands.
Leona Fleischmann, Director of Marketing Communications for Saint-Gobain Abrasives in North America said, “With the growing focus on eco responsibility, having this mark shows our support of greener ways in product designs, processes and end-user uses that make a measurable, positive impact on the environment. The goal was to keep it simple, distinctive and specific. The development of Green Tag creates a marketing platform to “tag” / promote initiatives associated to the manufacture and/or use of product(s) that help protect the environment.”
The e2010 program, aimed at saving 31 million sheets of paper used in printing electronic communications, is one of the “Green Tag” initiatives.
Not only “Green Tag”, Saint-Gobain Abrasives are also carrying out many environmental actions such as actively engaging in recycling and ISO programs and have won numerous awards, including the 1998 American Eagle Award from the ASMMA for the best recycling program among national manufacturers. The U.S. Environmental Protection Agency also awarded Saint-Gobain with the 2009 Energy Star Partner of the Year Award.
ISHRAE, the "Indian Society of Heating, Refrigerating & Air-conditioning Engineers" was founded in 1981 in New Delhi by a group of eminent HVAC&R professionals. Between 1989 & 1993, ISHRAE Chapters were formed in all major cities in India and also in the Middle East. ISHRAE has grown rapidly and now has more than 3000 HVAC&R professionals as members in 11 chapters in India and abroad. The Delhi Chapter is the first and the oldest of the constituent chapters of ISHRAE and has about 700 members.
Organizing successful international and national exhibitions is one of ISHRAE’s major activities. Its primary objective is to further the arts and sciences of heating, refrigerating and air-conditioning. ISHRAE has successfully organized more than ten exhibitions out of which four have been in New Delhi.
ISHRAE is an associate of ASHRAE(American Society of Heating, Refrigerating and Air-conditioning Engineers). ISHRAE Foundation Trust was formed in 1995, mainly to consolidate the Society's resources and to channel them towards projects necessary for achievement of Aims and Objectives, as listed below.
Aims and Objectives
Advancement in Heating, Refrigerating and Air-conditioning Engineering and related Sciences.
Education of interested persons in said sciences through lectures, demonstrations and publications.
Rendition of Career Guidance and Financial Assistance to students of said Sciences.
Encouragement of Scientific Research.
To establish facilities for testing, rating, certification of air-conditioning, refrigeration, and allied equipment and systems.
To offer consultancy services in the areas of Education and Training in said sciences.
To disseminate and make available to the Government, Industry, and General Public information relating to said sciences through papers, reports and periodic publications.
Priority Areas
Training
ISHRAE has recognised that training technical personnel is the single most important need at present, to improve the quality of HVAC & R work and raise it to meet ever-increasing customer expectations. It has also been felt that the existing manpower needs continuing education to equip them with the latest technology. This has become particularly relevant in the wake of globalisation of the Indian economy. Several industry leaders have also strongly expressed the need for such training.
Testing, Rating & Certification of Equipment and Devices
The last few years have seen a surge in manufacturing of both - major equipment as well as ancillaries and devices in the HVAC&R Industry. This has given rise to a need for a facility which will undertake testing, and will develop ratings which will help the industry establish reliable ratings and encourage development work.
Advisory Council
In addition to the Board of Trustees, an Advisory Council consisting of eminent persons in the fields of Air-Conditioning, Refrigeration and Allied fields, are to be formed to deliberate on the activities of the foundation.

Workshop for BEE Energy Star
A Half day workshop on “Workshop for BEE Energy Star Labelling and Energy Efficiency Improvement in Buildings‟ has been organised by ISHRAE.
BEE Star labelling program for buildings has recently been launched by Bureau of Energy Efficiency, New Delhi, for evaluating the energy performance of buildings. There was a provision of issuing “Energy star labels" to buildings as per their energy efficiency, similar to the energy star labels for home appliances (e.g. air-conditioners, tube-lights). Energy audit studies in buildings have shown large potential for energy savings both in government and commercial office buildings.
KOCHI: Incorporating energy-efficiency measures in buildings has the potential to save up to 50 per cent energy, since buildings are responsible for 40 per cent of the total greenhouse gas emissions.
For existing buildings, the savings potential through alterations and energy-efficient fittings is between 20 and 25 per cent. Even non air-conditioned buildings can go green, by making optimal use of wind and daylight and by adopting other environment-friendly measures. These were stated at ‘Go Green' – a seminar-cum-exhibition on green buildings, organised here on Friday by the Rotary Club of Thripunithura and KREEPA, as part of their Akshaya Vikas Project.
Making a presentation, Siva Kishan, chief executive officer of GRIHA – Green Rating for Integrated Habitat Assessment (which is the national rating system for green buildings), said the Energy Conservation Building Code regulates the usage of power in new buildings. “Green-rating mechanisms have been able to sensitise the construction industry to the benefits of integrated design and resource efficiency, from both the economic and environmental perspective. A rating system for India must respond to the country's diversity and help develop sensible solutions relevant to different building projects.”
In her presentation on ‘Green buildings – the potential to earn carbon credits,' Mayurika Chakraborthy, senior consultant with Deloitte Touche Tohmatsu India, said that less power consumption for lighting, air-conditioning, etc., would mean lesser usage of electricity from the thermal-power dominated power grid. “This in turn means an equivalent reduction in the amount of greenhouse gases like carbon dioxide that are released from fossil fuels. This makes a green building eligible to earn carbon credits.”
Guruprakash Sastry, manager (Green Initiatives) of Infosys, said the IT firm has been aggressively going ahead with its plan to design all its buildings as green buildings, to optimise energy performance and occupant comfort. “Sustainable buildings and saving every percentage of electricity and water make business sense and reduces expenses, especially when the annual electricity bills exceed Rs.120 crore and the water consumption is over 3 billion litres.”
Quoting Winston Churchill, Sathiaram Ram of IGBC, Hyderabad, said, “We shape our buildings. Thereafter, they shape us.” Buildings consume more energy than industry and vehicles. The green concept must become part of society's DNA. Even a 100-sq ft building can make a difference in shaping a better world. The intangible benefits of green buildings include better working/living atmosphere, he said and cited how a 20,000 sq ft green building saved Rs.9 lakh a year.
“India also has a great opportunity to export green-building technologies. Already, India has 508 green buildings spread over 358 million square ft area,” Mr. Ram said.
Imagine an intelligent glass that you could change from an ordinary looking transparent glass to a frosted glass with the flick of a switch. It could be used in windows of office and home replacing curtains, blinds or shades. It is perfect for skylights, sloped glass and window walls. It can be used in any type of window system including insulating, reflective or tinted glass.
Technology used:
It is composed of liquid crystal film(LC).LC film is made up of electrically conducive coatings, polymer matrix and liquid crystals.LC film has electrical wiring connected to a transformer to supply power.LC film is sandwiched between two layers of transparent conductive film and is then laminated between two sheets of glass. In the “on mode “glass is in transparent state as the liquid crystals line up. In the “off mode “glass is in frosted state as the liquid crystals turn to their normal positions.
On Mode Off Mode
.
By applying this switchable glass to windows in homes, offices and cars, the scientists estimate that reduced air conditioning needs and could result in an energy savings of up to 30%. The beauty of switchable glass allows you to control what type of lighting you want for your home. This glass consumes low electric of about 5 W/m2 .It is a better replacement of curtains and blinds .It can have many forms like curved, silk-screen printed or sand-blasted .It has an excellent projection screen, a reliable material and ideal for hiding precious items to be revealed only to selective customers . This type of glass can be used in partitions,glass doors etc. By applying a variable voltage to the window we can continuously vary the amount of transmitted light. Scientists at the AIST are currently working on maximizing the durability of the switchable glass, and overcoming the deterioration that arises due to repeated switching. Also, because the magnesium-titanium alloy can be applied to transparent materials besides glass, more applications may yet be discovered.
