Abstract: “A green building is an environmentally sustainable building, designed, constructed and operated to minimise the total environmental impacts. Green buildings have gained quite a lot of momentum recently. To further increase this momentum, conventional buildings need to be converted into Green (or sustainable) buildings. Even though this may mean an additional cost burden to improve and standardize the existing parameters to satisfy the Leadership in Energy and Environmental Design (LEED) certificate program, green buildings offer numerous benefits in the long run. This study focusses on converting a conventional building in Mumbai into a Green building, which should then satisfy the prerequisites of the LEED’s certification program and earn points to achieve different levels of certification. An existing building is re-designed, and a feasibility, economic and environmental analysis is done. The parameters to be re-designed are discussed, and the overall sustainability of the project is”
