BANGALORE: Bangalore has been one of the foremost cities to have warmed up to eco-friendly, sustainable homes. These homes, dotted across localities offer sky-gardens, service core as a buffer area, tropical landscape in the sky gardens, air spaces and wind scoops, natural ventilation, use of cavity walls for insulation, use of natural materials and reduced use of water and power resources. What Bangloreans are looking for is a combination of healthy living with lower operational costs.
“A green home is environmentally responsible and able to consume less energy, not only during its construction, but also while it is occupied. It has the ability to supplement its energy demand on its own by using renewable sources. It consumes less water and has provision for capturing and recycling this scarce resource,” states Mili Majumdar, Director, Sustainable Habitat Division, The Energy and Resources Institute (TERI).
Karnataka is home to 41 green buildings, the fourth largest figure for any state in the country. Of them, 39 are in Bangalore. Green buildings are fast catching the imagination of the people. Though the penetration level is just around 5%, the Indian Green Building Council (IGBC) is happy the residential sector is coming up with such buildings. Designed to rate new residential buildings individual homes, high-rise apartments, gated communities, row houses and existing residential buildings, IGBC Green Homes is probably the first rating programme developed exclusively for the residential sector. All builders have to do is register themselves for the green rating once construction is complete. The project team then evaluates all the possible points under the rating system using a checklist.
How are green buildings rated? Green Rating for Integrated Habitat Assessment (Griha) is a system for evaluating green buildings. “Launched by The Energy and Resources Institute, the Griha rating system is suitable for all kinds of buildings in different climatic zones of the country,” informs Majumdar.
According to Satish Magar, who is credited with creating one of the first sustainable models of private township development – Magarpatta City, Pune, sustainable development is that which raises the quality of life and serves the goal of achieving global equity in the distribution of the earth’s resource.
Going by industry prediction, the residential sector both independent houses and residential apartments are set to outnumber commercial buildings by 2030 in India.
