Sustainable architecture in India is uses mainly two approaches - Green architecture and Eco-Friendly architecture. Both focus on development that is essentially technology based.
Technology dependent Green Buildings require 10-25 % higher initial investment than traditional buildings. High initial costs and therefore dependence on corporate or government patronage has also restricted the adoption of this type of architecture to institutional building types with a few isolated exceptions of suburban residences.
Maximizing natural lighting and ventilation to achieve energy efficiency is often achieved at the cost of using large quantities of materials with high Embedded energy such as glass, and aluminum. The large amount of energy that goes into extracting, processing and transporting materials used in these buildings is neglected when calculating the building’s energy efficiency.
Environmental policy frameworks in India, and green buildings are often based on the contexts from developed countries. In adopting energy efficiency as the main criteria for green buildings in India, several other critical issues have been ignored. The issues of water and sanitation are more critical than energy efficiency.
