New Green Building Rating System for Residential Buildings in Tropical Countries

Green building is a sustainable system which promotes optimum use of natural resources and eco-friendly construction practices. Despite the benefits associated with green buildings, they are implemented only for 5% of the Indian construction industries. A number of researchers have investigated and found barriers which are hindering GBTs and practices in construction. Green building rating tools act as a yardstick to measure the greenness of buildings. Most of the GBRTs are country specific and energy specific. Even though many green building rating systems have been developed in past years by various countries, a system that is suitable for evaluating the residential buildings in the tropical countries has not been developed. So, it is essential to develop a rating system that is best for the context in the tropical countries. This paper reviews three prevailing GBRTSs across the world to study their differences and properties. The comparative study was conducted through case studies, and a new rating system was proposed.
