What does an ENERGY STAR score of 87 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 87 means the building performs better than about 87% of its national peers. BuildingCensus bands the score into report-card grades; 87 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. Polk St.: Polk St.'s 36.9 kBtu/ft² across 78,865 sq ft works out to about 2.9 billion Btu (853 MWh-equivalent) in 2024. The disclosure also reports 467,501 kWh of electricity and 13,354 therms of natural gas for the year.
