What does an ENERGY STAR score of 97 mean?

ENERGY STAR scores run from 1 to 100 and are computed by the EPA's Portfolio Manager as a percentile against similar buildings nationwide, adjusted for climate, size and use: a score of 97 means the building performs better than about 97% of its national peers. BuildingCensus bands the score into report-card grades; 97 falls in band A — high performer (85–100). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. In California, 65% of scored buildings are at 75 or above.

Site energy-use intensity (EUI) is the energy a building uses on site in a year divided by its floor area, in thousand Btu per square foot — lower is more efficient. Bellagio Villas (Bg49)'s 42.3 kBtu/ft² across 58,272 sq ft works out to about 2.5 billion Btu (722 MWh-equivalent) in 2023. The disclosure also reports 252,822 kWh of electricity and 17,306 therms of natural gas for the year.
