The unit of kilo watt hours per square meter per year is considered for rating the building and especially the targets air conditioned and non air conditioned office building.

OBJECTIVES OF GRIHA oMinimize the building resource consumption, waste generating and overall ecological impact. oEvaluate the environmental performance of the building holistically over its entire life cycle, their by providing a definitive standard for what constitute a green building. oBased on accepted energy and environmental principles, seeks to strike a balance between established practices and emerging concepts. oReduced energy consumption without sacrificing the comfort level. oReduced destruction of natural areas, habitats and biodiversity, and reduced soil loss from soil erosion etc.
- 7. TWO RATING SYSTEM IN INDIA LEED ? India adapted from USGBC is primarily based on per capita energy consumption in developed nations like the US which does not work in India since India¡¯s per capita energy consumption is very low compared to developed nations. GRIHA ? More suited to Indian climate, also unlike LEED it also not promote usage like glass and air conditioning equipment.
