"For the last couple of years, the NREL team has been documenting the operating performance of six green buildings to determine their actual performance relative to their design goals...

In an article in the September ASHRAE Journal, Torcellini, NREL colleague Ron Judkoff, and the DOE’s Drury Crawley report that energy performance in each of these buildings was “significantly better” than minimum code requirements, and each 'broke new ground' in sustainable design. But, the authors note, 'even though each building is a good performer, each used more energy than calculated during design.' "
