There's good news for proponents of sustainable design and construction who have been questioned about the validity of statistical analyses of benefits that are based upon modeling, rather than actual data. A comprehensive post-occupancy study of twelve green buildings by the Federal Government's General Services Administration using actual performance data has confirmed some of the benefits of green building. Eight of the buildings in the study were LEED Certified and the rest were built to other standards such as Energy Star or CA Title 24.
The graph above shows some of the results of the study, which was based upon a minimum of twelve months of operating data for each building beginning no sooner than six months after occupancy.

The entire study, “Assessing Green Building Performance,” is available in this section of the GSA site:
