A green building is one which uses less water, optimizes energy efficiency, conserves natural resources, generates less waste, and provides healthier spaces for occupants as compared to a conventional building. Considering the tremendous benefits that it offers, green building concept is gaining major importance in India. A common man wants an affordable house to live in which may fit in his pocket whereas the demand of the society is to go green as the pollution is increasing day by day. Affordable housing refers to housing units that are affordable by that section of society whose income is below the median household income. Though different countries have different definitions for affordable housing, it is largely the same, that is, affordable housing should address the housing needs of the lower or

middle-income households. Affordable housing becomes a key issue especially in developing nations where a majority of the population is not able to buy houses at the market price.
