New Building Institute (NBI):
The Energy Performance of LEED® For New Construction (NC) Buildings report was prepared by New Buildings Institute (NBI), funded by the U.S. Green Building Council (USGBC) with support from the U.S. Environmental Protection Agency. The NBI study was aimed at better quantifying the actual energy performance levels of green buildings. The report provided a critical link between initial modeling and actual performance outcomes of 121 LEED-NC buildings across the country that had been occupied for at least one year. The results look at the relationships of actual performance levels to other benchmarks, including initial modeling and ENERGY STAR® ratings.

Post-Occupancy Evaluation:
A post-occupancy evaluation was conducted by Dr. SueWeidermann, BOSTI Associates/WERA with CP and Associates of Kansas City, Mo. This study was conducted through the Office of Administration to quantify what aspects of sustainable design and office programming affect productivity within the building workplace and occupant workspace.
