IGBC Green Homes

Indian Green Building Council (IGBC) Green Homes is the first rating programme developed in India, exclusively for the residential sector. It is based on accepted energy and environmental principles and strikes a balance between known established practices and emerging concepts. The system is designed to be comprehensive in scope, yet simple in operation

IGBC Green Homes® Rating System is a voluntary and consensus based programme. The rating system has been developed based on materials and technologies that are presently available.

The objective of IGBC Green Homes® is to facilitate the effective use of site resources, water conservation, energy efficiency, handling of house-hold waste, optimum material utilization and design for healthy, comfortable & environmentally friendly homes.

The rating system evaluates certain mandatory requirements & credit points using a prescriptive approach and others on a performance based approach. The rating system is evolved so as to be comprehensive and at the same time user-friendly. The programme is fundamentally designed to address national priorities and the quality of life for occupants. The rating programme uses well accepted National standards and wherever local or National standards are not available, appropriate international benchmarks have been considered.
A Green Home can have tremendous benefits, both tangible and intangible. The immediate and most tangible benefit is in the reduction in water and operating energy costs right from day one, during the entire life cycle of the building.
