All buildings use resources such as land, water, energy, materials and time to fulfill the functional needs of a space over an extended period of time and leave impacts on the environment. As such, there can be no buildings without environmental impact. However, buildings can be designed to keep the impact of buildings within the carrying capacity of the local environment.
In such cases, successive generations can continue to benefit the same quality of environment where they inhabit. Such buildings and the manner of construction and operation are called green buildings. A building is green when it is resource-efficient and fulfills the functional requirement of the space with minimum negative impact on the environment over the longest possible time.
We are documenting such attempts in India corresponding to different functional needs of spaces. Keep checking the page as we keep adding more and more case studies. If you know of other examples which could be added here. Please suggest in the comments column below and we will be happy to consider them.
