While rapid urbanisation, growing cities provide various opportunities, there are fallouts in terms of proliferation of slums, high prices of land and building materials which render houses unaffordable for the segment at the bottom of the pyramid. Therefore, the need for adequate housing for the low-income groups will substantially increase.
Most importantly, while we create housing for these sections of the society, they need to be green too. The principles of green and sustainability are fortunately or unfortunately community-agnostic, in the sense that they also need to handle wastages a bit more carefully, be thrifty in the usage of energy & water, handle waste in a hygienic manner to avoid outbreak of epidemics, reduced use of virgin materials and above all enhance their own quality of lives.

With this background, IGBC has launched the Green Affordable Housing Rating. Some central indicators of green affordable housing would be:
The overarching objective of this rating would be to ensure a high degree of sustainability with no / meagre additional cost to the developer or the occupant. Therefore, the approach is to selectively adopt those measures that are simple and yet have profound impacts in conserving the environment.
