"LEED certification has never depended on actual energy use, and it's not going to," he says. "You can use as much energy as you want and report it and keep your plaque." The Existing Building rating system certainly does require actual energy performance.

EA, Any opinions on the use of the median vs. the mean as an indicator? I'd like to see the mean EUI for certain building types, is this available within the CBECS database? It is not clear to me how the median is a better indicator --especially concerning energy use--shouldn't the "excessive users" be fully accounted for?

Marc, I would say that comparing median and mean aren't normally a good way to go. You can check out the following link for a discussion about median and mean. http://www.buildinggreen.com/live/index.cfm/2008/9/2/Lies-Damn-Lies-and-Are-LEED-Buildings-iLessi-Efficient-Than-Regular-Buildings If you're trying to find the "best" average for comparison and your data has large outliers it would be more appropriate to use the median number. Go to CBECS and analyze the microdata (or just use Energystar) and review the following papers for additional insight on energy benchmarking.
