Sugarcane bagasse ash is the admixtures used in this study. As we are an agricultural country and we harvest at least two crops yearly. These two crops are harvested every year and the yields produce a lot of waste in the form bagasse. This produces around at least 20 to 30% of waste of the total yield. Traditionally this waste is disposed off by burning it in the open fields. This acts as a fertilizer for the next crop, but it has a very bad effect on the environment as the smoke generated increases the air pollution. Hence using this material as partial replacements to cement will not only prevent open field burning but will also reduce the cement consumption. The density of sugarcane bagasse ash is lesser than cement and hence reduces the weight of the concrete manufactured using this as partial replacement to cement[1]. There are lot of research studies about manufacturing of light weight concrete using light weight aggregates[2]. Hence in addition to the light weight aggregates if light weight mineral admixtures are also used they will further reduce the weight of concrete thus leading to reduction in self weight of the structure. Hence including sugarcane bagasse ash in concrete as partial replacement to cement will not only reduce and recycle the waste but will also produce an economical, sustainable and light weight concrete mix.

The negative impacts of the industries such climate change, global warming, ozone depletion and inefficient resource consumption have received a great concern and awareness among the public, politicians and academicians and this need demand of Green or sustainable design approach in all industries and sectors. Thus, a lot of efforts have been applied either in terms of theories or practices in order to reduce the adverse impacts of the industries. Green building rating tool, is a voluntary environmental rating system which evaluates the environmental design and construction of buildings, amid growing concern about urban environmental degradation. In this study, three primary rating systems prevailing in India are selected and analysed with the aim of providing insights into the current situations; highlighting the strengths, weaknesses, successes, and failures; and making recommendations for future improvements. The common aspect of all the rating system is to create a sustainable architecture in all respect so as to minimize negative environmental impact upon the environment. Certain analysis and data have been represented in this paper with the help of case study to highlight ambiguities and shortcomings in the weighting, scoring, and rating, which is mentioned in discussions. The three most prevailing rating system in India GRIHA, BREEAM and has been studied and compared with each other on the criteria upon which that are based.
