Superior Performance

Two recently released studies confirm what sustainability advocates have been saying for some time: Green-certified buildings outperform their conventional counterparts across a wide variety of metrics, including energy saving, occupancy rates, sales price and rental rates.

A study by the New Buildings Institute (NBI) finds that new buildings certified under the U.S. Green Building Council’s (USGBC) LEED (Leadership in Energy and Environmental Design) certification system are, on average, performing 25% to 30% better than non-LEED certified buildings in terms of energy use. The study also demonstrates that there is a correlation between increasing levels of LEED certification and increased energy savings, with Gold and Platinum LEED-certified facilities reporting average energy savings approaching 50%.

“The NBI study confirms that newly constructed LEED-certified buildings use significantly less energy than their conventional counterparts, and that they perform better overall,” said Brendan Owens, VP, LEED Technical Development, USGBC.

In addition, the report underscores that monitoring a building’s ongoing operations and maintena
