A Green Environmental Rating System applicable to Sri Lanka has been formulated as a ‘home-grown system’ with all norms acceptable to leading rating systems, after conducting research projects and workshops by an Expert Committee appointed by the GBCSL, with the assistance of national and international experts. The Expert Committee has studied the experiences of green building initiatives of India, China, Indonesia, Malaysia and Singapore, which are the fast developing economies in our region.
