 GRIHA GUIDELINES FOR GREEN BUILDINGS  7 DIFFERENT ASPECTS OF GREEN BUILDING DESIGN

1. Site Planning 2. Building envelope design3. Building system design – HVAC, Electrical, PHE4. Integration of renewable energy sources to generate energy on site5. Water and waste management6. Selection of ecologically sustainable materials  a) High recycled content  b) Rapidly renewable resources  c) Low emission potential 7. Indoor environment quality

 BASIC FEATURES

 1. Pre-construction stage 2. Building Planning and construction stages – land, water, energy, air, green cover 3. Building maintenance and operation stage
