A study performed by the New Buildings Institute (NBI) found that, on average, LEED-NC buildings are delivering anticipated savings. LEED energy use is similar to predictions—25% to 30% better than the national average. Average savings increase for the higher LEED levels, with Gold/Platinum buildings approaching the interim goal of Architecture 2030. Results for individual buildings, of course, continue to vary, which calls for further research and areas of improvement for LEED.

The study also demonstrates that there is a correlation between increasing levels of LEED certification and increased energy savings. Gold and Platinum LEED certified buildings have average energy savings approaching 50%.
