Environmental Impact of Buildings(why does it matter?)US Commercial Buildings Facts:

65.2% total US electricity consumption> 36% total US primary energy use30% total US greenhouse gas emissions136 million tons of US

construction/demolition waste (about2.8 lbs/person/day)

12% of potable water in the US40% (3 billion tons annually) of raw

materials used globally

LEED Concept and Intent

LEED is the standard for sustainable designworldwide.Design and construction practices that significantly

reduce or eliminate the negative impact of buildingson the environment.LEED is a point based system that ranks thesustainability of a buildings design by:

Certified (26 32 points)Silver (33 38 points)Gold (39 51 points)Platinum ratings (52 69 points)
