Conversion of an existing building into a green building takes into account the following aspects like water consumption, energy expenditure, recycling, biodegradability, environmental and sustainability concerning future demand, occupant well-being, environmental performance, and economic returns being improved. For rating an existing building or to suggest improvements, there are different sets of rules or guidelines in different rating systems. In our project, we have chosen Green Rated Integrated Habitat Assessment (GRIHA) which is India’s very own green rating system that helps to create sustainable habitat and eliminate adverse impact on the environment  In this project, we used the GRIHA Existing Building manual to study the existing features of ACE Engineering college under seven sections Site Parameters, Maintenance & Housekeeping, Energy, Water, Human Health & Comfort, Social Aspects, Bonus points and rated it based on theoretical parameters and suggested improvements where it is lacking, that can help in increasing the green performance of the campus and achieving better rating, if implemented.
