Sustainable construction movement has been deeply transforming the traditional construction sector. An important part of the sustainable construction delivery system, being sustainable/green building rating systems. This plays an essential role in implementing the sustainable principles into the construction industry and assessing the building’s rating. Most of the countries of the world have developed their own rating systems. All the rating systems are not the same as they all provide different weightages to the assessment tools different assessment tools are adopted according to their available resources and regional locations. Each rating system has its own method of calculating weightages. For evaluation of buildings in India the various rating systems can be used, but it may not give assessments, since the regional resources may be different. This Project aims to focus on the study of LEED, IGBC and GRIHA rating system, compare these three with regards to their assessment methods; scopes, performance criteria and energy rating scales are presented. Through this study, an attempt is made to make clear understanding of LEED, IGBC and GRIHA rating system assessment criteria that need to be considered during comparison. From this critical analysis it is possible to choose a rating is more applicable for India. In this study one case studies are chosen for analysis of rating system.
