GREEN BUILDING also known as green construction or sustainable building It is the practice of creating structures and using processes that are environmentally responsible and resource-efficient throughout a building's life-cycle
DEFINITION GIVEN BY INDIAN GRE REEN EN BU BUIL ILDI DING NG COUNCIL
"A
green building is one which w hich uses less water w ater,, optimizes energy efficiency, conserves natural resources, generates less waste wa ste and provides healthier spaces for occupants, as compared c ompared to a conventional building."
GOALS OF GREEN BUILDING

Solar window:Photovoltaïc windows not only pr ovide a clear view and illuminate r oo ooms, but also use sunlight to eff iciently help generate electricity for the building.
Roof window:A window:A sloped window used for daylighting.
Insulation in walls, ceilings, and floors: educes unwanted heat loss or gain and Insulation r ed can decr ease the energy demands of heating and cooling systems.
