Building Codes Assistance Project

The New Buildings Institute (NBI) has just released a report of measured energy performance of LEED buildings. The study gathered whole building energy data from 121 LEED NC buildings across the country that had been occupied for at least one year. It was prepared by NBI and funded by the U.S. Green Building Council (USGBC) with support from the U.S. Environmental Protection Agency.

Results showed that on average, LEED buildings are delivering the anticipated savings, performing 25-30% better than national average or modeled baselines. These and other results from this exploratory study suggest several opportunities for improved feedback tools, follow-up research on actual performance factors, improved modeling guidelines, and LEED program refinements.
