The CII-Godrej Green Business Centre in India was the first building to receive LEED Platinum certification outside of the US. It uses various sustainable design and construction features, such as a circular structure to maximize ventilation, local and recycled materials, passive cooling techniques like wind towers, a green roof for stormwater management and reduced energy consumption. The building aims to be a model for green building practices and environmental stewardship in India.
Sustainable building in India
- 1. Case study: Sustainable Building Structure (India) Estudiante: Professor: Auli Mellado Enric Satyanarayana Rao Rachakonda Environmental Management
- 2. General Details Project name : CII - Sohrabji Godrej Green Business Centre (CII - Godrej GBC) Architect : Karan Grover & Associates Investor / Owner: Confederation of Indian Industry (CII) Project built date: 2004 Environmental Management Area of project : 5 acres Built up Area : Built Up Area : 20000 sq ft Large area for landscape to enhance micro climate and for visual delight
- 4. CII - Sohrabji Godrej Green Business Centre (CII - Godrej GBC) • one of the 10 Centres of Excellences of the Confederation of Indian Industry (CII). • CII - Godrej GBC offers advisory services to the industry in the areas of Green buildings, energy efficiency, water management, environmental management, renewable energy, Green business incubation and climate change activities. • The Centre is housed in a GREEN BUILDING which received the prestigious LEED (Leadership in Energy and Environmental Design) Platinum Rating in 2003. This was the first Platinum rated Green Building outside of U.S.A and the third in the world. The Centre was inaugurated by H.E Dr A P J Abdul Kalam, the then President of India, on July 14, 2004.

- 5. The ROUND shape can support the concrete roof which gives uncompromised strength & security from any kind of disaster Environmental Management Limitless flexibility of design layout Unrestricted circulation of Air Takes advantage of views which is present At least 10 times strong then convectional square construction WHY – CIRCULAR ?
- 6. Climatic Design for Wind & Ventilation Environmental Management
- 7. Materials used & Green Facts • Concrete used for construction has 15% fly ash and 20% GGBS • Bagasse Board – by product of sugarcane industry-a good substitute for plywood or Particle Board It has wide usage for making partitions, furniture etc. • Eco-friendly method - does not involve any harm to the timbers, unlike Environmental Management plywood. • 66% (by cost) of the material was sourced within a radius of 800 km. • Of this, 95 % of the raw material was extracted or harvested locally. • An impressive 77 % of the building materials use recycled content in the form of fly ash, broken glass, broken tiles, recycled paper, recycled aluminum, cinder from industrial furnaces, bagasse, mineral fibres, cellulose fibres, and quarry dust. • Low VOC paints have also been applied
- 8. • Lighter than clay bricks. • High strength, practically no breakage during transport • Uniform size of bricks reduces mortar required for joints and plaster by 50%. • Lower water penetration, considerably reducing seepage of water through Bricks. • 65% walls in GBC are constructed with this material Environmental Management
- 9. Ground Hugging Construction VS • Like most olden systems of construction, structures are kept ground hugging ensuring natural modulation of microclimate and creating more interaction with nature. • Gives a sense of being close to nature Environmental Management
- 10. Green Roof & Water conservation • The green roof assists in increasing the lifespan of the roof and reducing the Environmental Management heat island effect. • Rainwater collection and reuse. • Waste-water and rainwater run-off is 100 % recycled and redirected to one of three ponds, to be used for domestic purposes. • 35 % reduction of municipally supplied potable water.
- 12. Passive Ventilation – wind tower • High efficiency HVAC system • Passive cooling system using wind towers. • Use of aerated concrete blocks for façades to reduces the load on air-conditioning by 15% to 20 % • This technique can be found in Persian architectural building constructions. Environmental Management
- 13. • A Wind catcher, Wind scoop or Badgir is a traditional Persian architectural element to create natural ventilation in buildings • Energy savings are achieved by the GBCs two wind towers. • Air, cooled by up to 8 ^C, is supplied to the AHUs, substantially reducing the load on the air conditioning system. • A heavily insulated roof further reduces the cooling load. Environmental Management
- 14. ENERGY FACTS • 1,022 m² of green roof, with vegetation covering 60 % of the total roof surface. • The remaining portion of the roof is covered by PV panels, meeting 20 % of the total energy necessities of the building. • Double-glazed units with argon gas filling to enhance the thermal properties of windows. • Energy-efficient lighting systems and compact fluorescent light bulbs. Environmental Management
- 15. Instead of using regular windows a mesh type ventilation is made of Bricks for fresh and cold breeze to enter Corridors Environmental Management
- 16. • Most of the path ways laid in landscaping are stones/tiles which were left over materials in other construction. • All of the new wood used was sustainably harvested, as certified by the Forest Stewardship Council. • A waste management plan in hand made it possible to recycle 96% of Construction waste. Environmental Management
- 17. • Some rainwater goes into the soil by the use of permeable grid pavers. • The remaining rainwater follows existing flow patterns and is collected in a water pond another traditional method of rain water harvesting, constructed at a lower end of the site. • All wastewater generated - recycled by "root zone treatment" simultaneously irrigates the vegetation. • Attractive alternative for wastewater management • Enhances the Landscape Environmental Management
- 18. Light & Ventilation • Building layout ensures that 90 % of spaces have daylight access and views to the outside. • North facades are glazed for efficient diffused light. • Low heat transmitting glass used. • Double glass to further reduce heat gain. • Natural lighting - no lights are used until late in the evening. • Minimum lux levels for all work stations have been ensured.
