LEED versus Energy Code

090630 LEED certified building performance v energy code min

The US Green Building Council (USGBC) has a building rating system which measures “green” parameters, meant to be used in the design of new and renovated buildings. LEED ratings can be assigned to buildings, ranging from Certified to Platinum.

I have suspected that many of the resulting projects were energy inefficient because of the rote design methods encouraged by USGBC to achieve their ratings, antithetical to mechanical and electrical engineering . Unknowingly USGBC have tested this premise. In the graph are the results of a sampling of certified buildings USGBC examined.

21% of the buildings tested were not able to meet the efficiency minimums established by their respective governing energy codes. Amongst the buildings that failed were LEED Platinum-rated structures.
