In this 21st century, the world around us is dramatically occupied by multi-storey buildings. The number of buildings constructed per year is getting increased. As a result of this natural resources are getting exploited and polluted to a greater extent. If this status continues, then the future sustainability will be a greatest interrogation. This can be overcome by the construction of the green buildings. The green buildings are totally different from the conventional buildings. The green buildings are the buildings constructed with the energy efficient materials.

The awareness about the green buildings and the necessity of the green buildings has their wide spread all over the world. Many nations started their own organization to award the buildings, constructed as per their rating system. India also includes itself in that list. India adopts a rating system called GRIHA as the National Green Building Rating System of the country. The highlight of the GRIHA is that it also rates the non-air conditioned buildings as green buildings. The CESE building of the IIT Kanpur is the first GRIHA rated building in India.

The Indian Green building council (IGBC) awards the buildings with certified, silver, gold and platinum as per the point that they are getting. IGBC also certify the buildings with the LEED certification under the license of the USGBC. Let us see some green buildings in India with LEED certification.

CII-Sohrabji Godrej Green Business center

CII-Sohrabji Godrej Green Business center at Hyderabad inaugurated on 14th July 2004 by the then president of India H.E Shri A P J Abdul Kalam. This building earned the LEED platinum rating in 2003. This was the first building to receive the platinum certification outside US and also first in India. This building is designed in such a way to collects the rain water, relies on the natural lighting’s and make use of the solar power.These results in the conservation of energy by 55 percent, compared to the other conventional buildings.

ITC Green Center

 

ITC Green Center located at the city of Gurgaon, Haryana was opened in 2005. This building received the LEED platinum certification. This building recycles and reuses all the water that lands on it, results in zero water discharge. This building uses insulated glasses that keeps the heat out and allows the natural light to transmit into the building. This building saves the energy and water by 51 percent and 40 percent respectively. This building has saved Rs.1 crore in power cost annually. The construction of this building uses certified woods. This building uses CO2 Monitoring system to improve the quality of the air to provide the fresh air.

This is the first bank in India to achieve the LEED platinum for commercial interiors and also the first platinum interiors certification outside US. It cuts the cost of energy by 34 percent and air – condition cost by 19 percent. Thus the India is marching towards an environmentally friendly future.

The MIPIM Asia Awards are given to real estate projects in the Asia-Pacific region that stand out for innovation in design and excellence in energy performance, among other criteria. There are eight categories of awards that are given away, and the 2010 awards were given away at Hong Kong, on November 10th.

Honours for Parkview Green

Parkview Green was one of three awardees under the Green Building Category. This is the first time a Chinese project has won this Green Building honour. This exemplifies China’s active participation in building a green future. Parkview Green also has the pre-certified LEED® Platinum for core and shell from the USGBC. On completion, it is all set China’s first LEED® Platinum certified urban mixed-use development.

Parkview Green

Parkview Green FangCaoDi is a building that houses world-class shopping centres, Grade-A office complexes and a boutique hotel. Located in Beijing, China, it was designed by Integrated Design Associates (IDA) and given life by developers Beijing Chyau Fwu Properties Ltd.

Parkview Green assumes a unique pyramidal structure with both aesthetic and functional appeal. The building comprises four towers – two 9-storey & two 18-storey towers. Four of these towers are meant primarily for Grade-A office space. There is 82000sq m of office space in total for multiple tenants, connected by air bridges. There is also a commercial business space, a 100 room boutique hotel and 50,000m2 of luxury retail.

The Shield

All four towers are enclosed by a transparent environmental shield. This shield is made of steel, glass walls and an ETFE membrane system roof, and is controlled by an automated Building Management System. The double-glass skin creates an air chamber that stores the thermal energy and reduces energy footprint. It also forms a natural ventilation system that circulates fresh air between the ceilings and floors, allowing the building to “breathe” easily and naturally.

The climate inside the shield is relatively uniform.  The shield increases thermal insulation, thus reducing energy consumption. It limits the need for air conditioning in summer and reduces heat loss during winter.

Ventilation louvers are installed at the top of the envelope. These act as chimneys, allowing the warmest air to escape and creating an upward flow of air. As the air escapes, cooler air is drawn up from the bottom of the building, allowing for air movement and natural ventilation.

With its sustainable architectural design, Parkview Green FangCaoDi saves up to 44% in energy consumption and 48% in water consumption. Parkview Green can also recycle 81% of its construction waste material. Moreover, 25% of its total building construction material is made up of recycled content.

More on Parkview

Parkview sports a 236-metre pedestrian bridge that spans the complex, offering a bird’s-eye view of shops and the public plaza. A series of lifts and 18 six-meter-long escalators have been installed. The premium shopping centre offers luxury merchandise on four levels. Boutique Cinema, a mini-spa and a gym on a terraced garden sky lounge on the 18th floor are some other perks the building offers. Fashion shows, car launches, art exhibitions and other attention-grabbing events will be hosted here.


South India is now home to an iconic “zero energy and solar powered home”, a masterpiece in Green architecture that is set to start a welcome trend in controlled energy consumption in residences.

This zero energy space project was exhibited at the Indian Green Building Congress (IGBC) 2010, held at Chennai from 6th to 9th October last year. The IGBC is Asia’s largest Green building conference. The project was also showcased at the Economic Times’ ACEtech – Mumbai as well as Delhi chapters. These are Asia’s largest construction related expos.

About 60% of this home’s energy requirements are met by the conventional sources, while solar power supplies the remaining 40%. Nevertheless, there is no compromise on performance and comfort.

The chief sponsors of this Green initiative are Aluplast Windows, Breezair, Everest Industries, Nippon Paints, Supreme Pertochem and Roca.

EVEREST FIBRE CEMENT BOARDS

olive-8-condoEmerging or the budding buildings started to imbibe various energy efficient and green features in its construction, which will definitely be a cornerstone for its popularity and also a greatest measure to cut the cost incurred for the energy usage. Olive 8 building includes itself in the list of the green buildings by enclosing plenty of eco-friendly features.

This striking building has also officially earned the LEED silver Certification by the USGBC and moreover this the first time that the hotel/condominium building to receive the LEED silver certification. The olive 8 hotel is also one of the 20 green hotels in the U.S. Let us sail through the different construction features of this building.

Olive 8

Olive 8, fairly known as Hyatt at Olive 8 is located at Downtown Seattle, Seattle, Washington. The very luxuriate Olive 8 is a 39-storey building playing a dual role of hotel and condominium. Olive 8 contains 346 rooms in its first 17 floors and the rest of the 22 floors are occupied by 229 urban condos. This Olive 8 building was planned and designed by R.C. Hedreen Company. Mr. Hedreen aimed to make this building to achieve the LEED certification. Keeping this in mind, he redesigned the old plan of this Olive 8. At last he deserved it by giving a fabulous healthy and wealthy indoor environment to live and work.

Facade

olive81The façade of the Olive 8 is a 100 percent glass exterior with blue architectural glass. The glass façade and the windows from floor to ceiling allow the abundant natural light to flood inside the building. Thus saving the energy used for artificial lightings. Triple-paned glass and a special coating on the exterior protect the excessive heating to the interiors.

 

Rooftop

The roof top of this building is one of the largest living rooftop in Seattle city. The roof is planted with native plant materials and traditional roofing material, is the greatest highlight. These plants on the roof reduce the amount of heating and cooling. The high island effect is reduced by a high performance ultra reflective surface membrane on the rooftop. It also decreases the amount of rain water flooding the storm sewers by absorbing and retaining the water in their roots and in the soil.

Energy conservation

Olive 8 is expected to save 23 percent of energy more comparing to the other conventional building of similar size. All rooms of the Olive 8 are equipped with watt stopper ® technology that automatically turns the lights off when there is no foot prints. Olive 8 avoided volatile organic compounds by using low or no-VOC paints, solvents and carpeting. All the cleaning products are low-VOC and 100 percent toxic free. Washers, Dishwashers and refrigerators or Freezers are Energy Star® rated.

Water conservation

It also saves 36 percent of water, which is nearly equal to 2.4 gallon per year. It includes low-flowing plumbing fixtures, uses one gallon per minutes which is really less when compared to the traditional shower heads. Toilets and urinals use dual-flush system that saves 29 percent less water per flush. Additionally super efficient irrigation system tends the landscaping maintenance to use minimal city water and results in the 99 percent water savings, which is approximately equal to 24,000 gallons of water per year. A very low-chemical mechanical water system is used, which uses very less potable water.

Seattle Steam Company, which is providing the heating for the building, will reduce the carbon foot prints up to 50 percent by using biomass as fuel instead of natural gases. Olive 8 give more preference to the highly fuel-efficient vehicles in the parking area and outlets for electric cars in the underground parking area. Mostly, 95 percent of the construction debris is diverted from the landfills disposal by directing materials to be reused and recycled.  

These above mentioned features led this building towards the LEED certification. The LEED silver certification signifies the building’s environmental leadership in the industry, both locally and nationally.

NASANational Aeronautics and Space Administration (NASA), an agency of the United States Government is responsible for the public space programs of the nation. It is a very well known agency with most stunning and innovative projects in their hands. To set as an outstanding example for other agencies, NASA guys planned to work on a project, which will be expected to shutters the ground by its high performance. This amazing green project is none other than NASA’s most sustainable base. In order to launch this energy efficient and environmentally friendly building, they decided to use their lunar base technology.

This new building is designed in such a way that it will gain the platinum rating under the LEED new construction standard for environmentally sustainable construction. This building is budding in Ames research center in Moffett Field, California. This new building of NASA is designed by McDonough with his partners and AECOM. This project will cost about 20.6 million and its construction will be completed by 2011.

Three key goals

The three key goals of this building are to achieve the zero net energy consumption, to use 90 percent less drinking water or the water which is potable, when comparing to the usage level in other equivalent size conventional buildings and finally to reduce the maintenance of the building.

Highlight of this building is the usage of natural ventilation complemented by the geothermal systems, increases the building sustainability. Nearly 72 geothermal wells with ground-source heat pumps will be installed to promote the objectives of sustainability of the new building. This building will also provide a parking and a landscaping with California-native plants. This advantageous project will include a very sophisticated system for solar water heating, fire detection and suppression, advanced lighting, security and communications operations.

These above mentioned systems will be deliberated in a way that they can act automatically according to the changes in sunlight, temperature and wind and use resources to maximize the performance of the building. Radiant cooling, intelligent buildings systems and on-site photovoltaic energy generation will also be incorporated in this project. A site storm water management is also going to be installed in this base building. Optimization of water comes from use of natural landscape; non-potable irrigation system and on-site water treatment by an Eco machine are other added features of this building.

The interior of the building includes large column-free spans, which helps the building to adopt itself to the changing needs of the programs and a structural exo-skeleton which renders the repairs easier even after the earthquakes. The real crown of this project will be the intelligent computer-controlled system. The computer in this sustainable building along with the internet connection can forecast the weather of the local area; along with integrated occupancy sensors adjust the heating and cooling system. These computers also control the windows in order to take advantage of passive cooling.

Base building includes few new facilities such as structural steel frame, 4645 square-foot open- collaborative workspace, a glass-walled atrium and so on. It is very clear that NASA has anchored its flag on the planet earth by contributing this base building in California. This sustainable base building will be an outstanding and competitive example for the present and future green buildings.

Nowadays, not only the factories, industries start their journey towards the green future but also many educational institutions like schools and colleges started to prepare their students towards the energy efficient green buildings, green economy and green jobs. By this the colleges can create good citizens for the future with the greater knowledge about the environmentally-friendly features. Some of the colleges started to offer green building courses for the students as a part of their contribution to the eco-friendliness. Here are three colleges that include various excellent the green practices:

College of the Atlantic

college-of-the-atlanticCollege of the Atlantic (COA) at Bar Harbor, Maine, USA was inaugurated on Oct 8, 2006 by the president David Hales had taken an oath to be a Carbon NetZero college by the end of 2007, to achieve that mission, the students, faculties and the staff worked together and carried out many researches and analyses to offset the green house gas emission. As on Dec 19, 2007, COA invested in a green house gas reduction project operated by The Climate Trust of Oregon to offset the 2,488 tons of carbon output over the past 15 months.

By obtaining the electricity through a low-impact hydroelectric generator in Maine, COA reduced its annual green house gas emission and this will be further reduced by 22 percent or about 450 tons by next year. Incandescent light bulbs have been replaced by compact fluorescent where possible. This college makes use of the natural light by installing light shelves, which bounces the light from the windows to ceiling to lights the interior of the rooms. Commuting methods such as carpooling and biking promotes the employees to work from the home.

COA uses only certified woods, not from the old-growth forest and no materials that emit gas-chemicals. COA uses a renewable wood pellet boiler to heat 20 percent of the college campus. It keeps the temperature as 65 during the day time and 50 at night time. Coolant from air-conditioning in library stacks and kitchen used to preheat the hot water. All toilets, urinals, faucets and shower heads use less than three gallons of water.

Berea College

berea_kyBerea College at Berea, Kentucky, amazingly locates an Ecovillage that occupying a 5 acre eco-friendly community. The complex includes 50 apartments, a state-of-the-art Child Development Laboratory, a common house and a Sustainability and Environmental Studies (SENS) demonstration house. The Ecological machine, wetlands, permaculture food forest and individual gardens are the other community features. This energy efficient Ecovillage reduces the energy usage by 75 percent, water usage by 75 percent.

Ecovillage recycle and reuse 50 percent of the sewage and waste water. Skillfully, Ecological machines are used to convert the sewage water to swimmable quality water. This village also incorporates passive solar heating, photovoltaic panels andwind-powered. The roof top captures the rain water used for the landscape irrigation and for the production of fruits and vegetables. Berea college maintains it own farm to provide the organic produce, beef and pork.

Evergreen State College

evergreenGreen roof of the new building is a greatest highlight of Evergreen State College at Olympia, Washington. This building is being evaluated for the LEED-Gold rating under the USGBC. This tremendous green roof builds 24,000 square-feet on 13 separate green roof areas. This green roof is a live visual representation to develop the sustainability. Roughly, $18 is incorporated for a square-foot with polyisocyanurate insulation with an R-value of 21, bitumen roof system which incorporates recycled materials and stainless steel flashings.

Green Roof uses Garland’s filterdrain 110 as the drainage layer. It is a very high density polyethylene filter fabric fused to a geotextile filter fabric. A drip irrigation system will be used only during the severe drought periods. Important advantage of this green roof is it reduces the size of the storm water preservation ponds. The green roof collects, filters the rain water incident on it and allow it to flow into a 20,000 gallons reservoir tank, which is designed in such a way to release water back to the environment. The students of this college use benches and patio  areas, arranged around these green roofs as an interaction place with their staff members.

austinhomeMany multi-story buildings and also many skyscrapers landed their foot as green buildings in this world. This is because they wanted to contribute themselves to the list of energy efficient buildings that reduces the carbon emission and saves the energy to greater level. Not only the multi-story buildings but also few homes started to twinkle as green houses now. Jointly all these efforts directs us towards a pleasant eco-friendly atmosphere. The first green house was probably built in Roman times to cultivate to cultivate exotic fruits and vegetables. Fortunately, new Austin home affix itself in the catalog of green houses.

Austin home, a good looking home covers an area of about 3,266 square-feet. This home earned the top ratings from three widely reputed green building programs in Austin, LEED – Platinum, NAHB Model Green Building Gold and Austin Energy Green Building 5-star. Additionally this house also earned the Energy Star Qualification. The builder of this energy efficient home is Durrette Interests, Austin Architects: Barley & Pfeiffer Architects, Austin.

Austin home includes various techniques such as advanced framing technique, energy efficient windows, low-VOC interior finishes, a tank less hot water heater, dual-flush toilets, a very compact fluorescent light fixtures and so on. Austin homes uses 3-KW solar photovoltaic array on its southeast roofline, which conserves 25 percent of energy. A light-colored galvalume prosnap 100 recycled-metal roof contains a self-venting radiant barrier system, which consists of the venting path between the underside of the roof and the roof decking, to maintain attic temperature low. This also acts as a big umbrella for the house.

The Austin home also contains a very unique and special attic, sealed with the ventilated roof, which allows very little amount of the heat incident on the roof to penetrate into the house. Spray-foam attic insulation is used, which is used to reduce the humidity of the home during the summer, keeps the home warmer in winter and also decreases the accumulation of dust. Windows and overhangs are designed and sized in such a way to provide summer shading yet allowing abundant daylight and natural winter heating from the sun. Unconventional-looking cloth canopies hanging on the aluminum framing helps to shade the windows at certain of the day. 

First-floor screened porch on the prevailing-breeze side of the house and a stair tower on the opposite side maximizes the potential of the home to responds to the solar and to other climatic considerations. Unbelievably, this porch is very cool even without any air conditioners. The passive thermal siphoning facilitates the natural cooling and ventilation. A Carport – an open-sided shelter for vehicles, performs double-duty as a covered play area that makes the prevailing breezes to keep it cool and comfortable, even in the times of summer. The breezes vent out of the 5-foot-alley between the house and detached garage.

High energy efficient air conditioning is used to stay cool and comfortable. Austin home is sited in the neighborhoods of the USGBC standards. This house is at a walk able distance from the work, workshop and shops. Merely for its location, Austin house earned 10 LEED points.

American Institute of Architect (AIA) – a professional organization for architects in United States unveiled a list of Top 10 environmental friendly green projects for 2009. After analyzing various energy efficient features of the numerous buildings, AIA generated this top 10 list for green buildings. Those remarkable green buildings are listed below:

Charles Hostler Student Center

charlesCharles Hostler student Center located on the campus of the American University of Beirut is a startling example for how a perfect campus should be. This building covers an area of about 204,000 square feet. Here the project is organized as a cluster of interior and exterior spaces rather than a single building. This allows the building forms themselves to redistribute the air, activity and shade. The east-west orientation of the building forms helps to provide shade to the exterior courtyards, which reduces the amount of the southern exposure. That orientation also directs the nighttime breezes and the daytime sea breezes for cooling the outdoor spaces.

The rooftop of this study center includes a green space, which allows a very pleasurable physical and visual integration to the upper campus. This green rooftop reduces the amount of exposures to the sun. Shading and ventilation process increases the amount of usable program areas of outdoor spaces.

Chartwell

chartwell_schoolAn outstanding and stunning Chartwell school campus occupies an area of about 21,200 square-feet. Excellent daylight inside is provided by the tall and north-facing glass windows and clerestories. This helps in achieving the net-zero electrical goal of that school. Sloping shed roofs helps in good photovoltaic orientation of the building. Radiant heat plays a very beneficial role in providing a quite and pleasant environment to the students of the school and also reduces the size of the mechanical equipments and mechanical rooms. Framing the structure at the two feet on the centre reduces the amount of materials used on the project and thus saves the overall construction cost.

Gish apartment

gish7Gish apartment is a 35-unit transit-oriented family apartment in downtown San Jose, California. This ground breaking apartment covers an area of about 75,200 square-feet. This is the first US housing apartment to receive the LEED for homes and LEED for new construction Gold certification. By choosing a site adjacent to light rail and reserving 35 percent of units for tenants with developmental disabilities, the owner earned a major parking reduction from the city. As a result, the project has a high housing density of 81 units per acre. Other energy efficient features of this apartment includes the reuse of urban brownfield site, a roof-top photovoltaic array, high performance insulation in 2×6 exterior walls, double-glazed windows, and high-efficiency heating and hot water system

Great River Energy Headquarters

greatriver_mnGreat River Energy (GRE) is Minnesota’s second largest electric wholesale supplier, generating and transmitting the electricity to 28 distribution cooperatives serving more than 620,000 residential, commercial and industrial customers. The headquarters of the GRE covers 166,000 square-feet area. It is a four-story building with concrete frames and architectural glass curtain walls. GRE wished to design its headquarters as a model of electric efficient building, which could be adopted by the electric co-op members across the state. The major goal of these members was to reduce the demand for large and coal fired generating plants. They also wanted to meet the new demands with the wind power or with other renewable resources.

This building achieved most of the features of a green building by providing abundant day light, view to the exterior, exceptional indoor air quality and a quality work environment within a reasonable budget.

Jewish Reconstructionist congregation

jewEye-catching Jewish Reconstructionist congregation (JRC) in Evanston, Illinois covers 31,600 square feet. This new synagogue for Jewish Reconstructionist congregation building earned the LEED Platinum certification. Perimeter space of this building has 9.5 ft ceilings. This enhances the day lighting and natural ventilation. The synagogue is a wooden box clad with reclaimed cypress, with spectrally selective, low emissive glazing. The reclaimed cypress is also used in the indoor of the worship spaces. At the perimeter sites of the building Gabion walls filled with waste masonry are used. Most of the floors are made up of polished concrete. Thus there is no necessity for the floor covering. Paints and finishes with low level of volatile organic compounds are used throughout the building.

Portola Valley Town Center

portola-01Portola valley town center was constructed at Portola valley in California by demolishing three town structures – a library, a community hall and a town hall. The materials of the old town center were reused as beams, paneling, countertops and structural fills. The new building is 20 percent smaller than the old. The salvaged wood is used for the exterior siding and louvers and the local eucalyptus is used for the wood flooring. The concrete mixture is 70 percent slag. Because of such energy efficient measures, the carbon emission is reduced by 32 percent.

Energy efficiency is achieved greatly by proper building orientation, day lighting, natural ventilation, sunshades and thermal mass. Small and efficient air conditioning units pre-cool make-up air and eliminating the need of full air conditioning. This building includes a photovoltaic system with 76KW, which supplies 40 percent electricity to the building. The non renewable energy cost is reduced by 51 percent and the carbon consumption is reduced by 76.2 tons per year. Strikingly, an abandoned culvert will become a cistern for storing 40,000 gallons of rain water.

Shangri La Botanical Garden & Nature Center

shangrila1Shangri La Botanical Garden & Nature Center in the heart of Orange, Texas is a project which involves in the restoration of the land, which had been closed to the public for 50 years. This building finished one edge of its complex with the cues taken from the brick, glass and steel from the green houses built in the early 1920s. The nature discovery lab and pavilion, outdoor classrooms, bird blind and boat house are designed to float above the land on helical pier foundations and for very minimal impact. Photovoltaic panels are used for the power generation for these structures. Proudly this green building earned the LEED platinum certification.

Synergy at Dockside Green

Synergy_BridgeDockside green covers wide area of about 1.3 million ft2 in the heart of Victoria, BC. This resourceful building includes many environmental friendly features like rolling canopies that are used to control glare and solar radiations. Occupants have a control over their spaces with the help of dashboards, which also controls the canopies as well as heating and ventilation. There are also green roofs which includes planting spaces for vegetables and a green way to support the social equity and local food production. These green roofs and spaces help in minimizing the heat island effect. It also takes away the great burden of the city storm water system by allowing the storm water to leak into it.

Meanwhile all the waters landed by the rain gets collected and reused for the purpose of irrigation, toilet flushing and for the greenway treatments. A wood-fire combined heat and power plant will produce the heat and hot water to the entire usage. This greatly combined along with the hydropower-based electricity, will reduce the carbon emission to a greater extent. Highly renewable resources such as bamboos and cork were used as the interior finishes and the materials with the low level volatile organic compounds were also used in the construction.

The Terry Thomas

Weber_Thompson_HQThe Terry Thomas, a gorgeous green building in Seattle, WA cover 37,000 ft2 office space in four floors. The highlight of this building is its less dependency on the energy. A holistic design concept was tailored with specific sites to provide day light, ventilation and reinforced community connection to the tenants of the building. This indirectly resulted in increase in the productivity potential. By this process, they also created an experimental and educational tool for promoting sustainable design.

World Headquarters for the International Fund for animal Welfare

10187_2_Animal3The International Fund for Animal Welfare (IFAW) is located in Cape Cod in yarmouthport, Massachusetts. This new headquarters received the LEED Gold certification. This project aims to create a restored meadow and to re-establish a natural habitat with native vegetation. IFAW also incorporated low-tech, low-cost and sustainable features such as orientation, natural day lighting, ventilation and very efficient mechanical system. This green house also incorporates a plan that reduces the square footage by 50 percent per person during the elaboration of the workspace and increasing the employees.

Rating the buildings according to the green building features leads to the increase in the awareness about the energy efficient green buildings in the world as well as it gains reputation to the buildings.

In this 21st century, the world around us is dramatically occupied by multi-storey buildings. The number of buildings constructed per year is getting increased. As a result of this natural resources are getting exploited and polluted to a greater extent. If this status continues, then the future sustainability will be a greatest interrogation. This can be overcome by the construction of the green buildings. The green buildings are totally different from the conventional buildings. The green buildings are the buildings constructed with the energy efficient materials.

The awareness about the green buildings and the necessity of the green buildings has their wide spread all over the world. Many nations started their own organization to award the buildings, constructed as per their rating system. India also includes itself in that list. India adopts a rating system called GRIHA as the National Green Building Rating System of the country. The highlight of the GRIHA is that it also rates the non-air conditioned buildings as green buildings. The CESE building of the IIT kanpur is the first GRIHA rated building in India.

The Indian Green building council (IGBC) awards the buildings with certified, silver, gold and platinum as per the point that they are getting. IGBC also certify the buildings with the LEED certification under the license of the USGBC. Let us see some green buildings in India with LEED certification.
