WHAT IS LEED (LEADERSHIP IN ENERGY AND ENVIRONMENTAL DESIGN)?
• Established in 1993
• The U.S. Green Building Council is committed to a sustainable, prosperous future through LEED
• LEED is a certification system to rate how green a building design and construction is.
• Can be used on both public and private buildings; including residential homes, commercial buildings, hospitals, schools, ect.

DOWNFALLS OF LEED
• People more concerned about points then being innovative
• Expensive or Time Consuming
• Needs constant updating
• “One-size-fits-all” approach to geography
• Based on a physics professor at Oberlin College, LEED Certified buildings use more site and primary energy then other medium energy non-LEED buildings.

AN EXAMPLE OF LEED DOWNFALL:
COOKFOX Architects, Bank of America, Manhattan, N.Y., 2009
• 55 Stories Tall (+3 basement floors)• 2,100,000sqft of Office Space• First commercial high-rise of it’s size to get a Platinum
LEED rating• Uses twice as much energy as the the Empire State
Building Their trading floor, making up a third of the tower,
uses up most of the energy:o Each desk has five computer monitors to a desko The system to heat, cool, and light the huge
trading floors
