• Buildings constructed in 1980’s and 90’s are same as today .
• Difference being there was no measurable standards for determining the sustainability of the building.
• Variety of assessment tools have been developed all the world
• First environment certification was introduced in 1990 in UK: Building Research Environmental Assessment Method (BREEAM)
• LEED was also quite substantially based on BREEAM
• LEED rated or GRIHA, GREEN STAR are all used to evaluate building's level of sustainability and ‘reward’ the projects that have achieved those levels
LEED – A TOOL
• LEED is one of the tools for assessing or designing green buildings
• LEED came into being 1998 under US Energy Council
• In India it has 5 certified Green projects
• 23 registered buildings are upcoming
• LEED can be divided into two main components conceptual and contextual
• LEED primarily awards points on projected performance outcomes
TERI GRIHA
Green Rating for Integrated habitat assessment
• TERI's green building rating system (TERI–GRIHA) has been developed after a thorough study and understanding of the current internationally accepted green building rating systems and the prevailing building practices in India
• The primary objective of the rating system is to help evaluate the ‘greenness’ of the buildings
• A building is assessed based on its predicted performance over its entire life cycle – inception through operation
• It has 32 criteria and total 100 points on basis of which building are rated
• There are currently 7 certified building
GREEN INITIATIVES
Case Studies _Wipro Building
• Wipro Software Development Centre at Gugaon has achieved the Platinum rating from US Green Building Council in LEED category
• The building of 20,000 square feet consists of exhibition spaces, seminar halls, offices, meeting rooms, and a cafeteria
• Building envelope constructed with fly ash
• The building layout ensures that 90 percent of the spaces have daylight access and views to the outside
• The documented reduction of harmful emissions achieved by the design, siting, and construction of the building is 62 percent for carbon monoxide, and 63 percent for hydrocarbons and nitrogen oxides.
Panchshila park Colony
• Total rooftop and surface area 3,57,150 square metres (sq m)
Average annual rainfall in Delhi 611 millimetres (mm)
Total volume of rainwater harvested: 1,74,575 cubic metre (m³), or 174,575,000 litres
This represents 80 per cent of the total water harvesting potential
• The project was implemented in June 2002
TERI CAMPUS, Gurgaon, Harayana
• TERI has a 36 hectare campus in Gurgaon, Harayana
• The temperature inside the building is maintained at 20-30 degree though out the year
• TERI generates its own electricity upto 10 kilowatts using photovoltaic and runs its lights on 50 kilo watt biomass gasifier
• It uses features like recycling of water
• Solar water heaters
• Underground earth tunnels
• Energy efficient lighting
TERI campus at Gual Pahari is an example at neighborhood level of efficient and environmental conscious design
It uses a combination of technologies to ensure minimum environmental degradation
