Henry (& others) should have read the Development of a California Commercial Building Energy Benchmarking Database & Energy Benchmarking In Commercial Office Buildings DOE papers. They said what NBI said before they said it. :)
"Points-Based Rating Systems, including (LEED), do not allow comparisons against other buildings, rather, they provide standards and guidelines to measure how efficient and environmentally friendly a facility is and compared it to best-practice standards."
"Statistical distributions of office building EUIs developed from CBECS data can be used for comparing the performance of an individual building to others within its respective census division. Median EUIs are more reliable comparators when it is desired to compare the energy use of a sample of local buildings to CBECS census division statistics. Averages can be strongly influenced by a small number of buildings with excessive individual EUIs. This occurs in the CBECS database and will occur in local sampling of office buildings."
