Sustainability of Green Buildings and Comparing Different Rating Agencies

The excessive use of all the energy resources like land, water, and the air is part of industrialization and urbanization which creates an imbalance of the natural ecosystem. As a result of rapid industrialization, tons of waste are getting produced every year, posing damage to our environment. Also, a huge amount of waste is included from the demolished buildings, large structures made up of sand, gravel, concrete bricks, etc. Recycling of this demolished material as aggregate for the construction of new house old buildings, industries can fill the demand–supply gap and also help us reduce the waste produced. To compete with the above requirements, green building construction is essential for the reduction of depleting ecosystem. This paper initially focuses on the systematic study of the literature of GBRS adopted in different countries and reviews them individually. A quick case study of three leading green buildings of India is also reviewed in this paper. Various green building rating agencies such as LEED, BREEAM, CASBEE, GRIHA, and GREEN MARK are disclosed below. This paper also focuses on the minimum energy approach and also emphasizes the green energy concept to be adopted in the various rating agencies, and also, a quick comparison of various leading rating agencies has been made in this paper.
