What does an ENERGY STAR score of 77 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 77 means the building performs better than about 77% of its national peers. BuildingCensus bands the score into report-card grades; 77 falls in band B — above median (70–84). 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. 310 Townsend Street Homeowners' Association's 22.0 kBtu/ft² across 92,647 sq ft works out to about 2 billion Btu (597 MWh-equivalent) in 2022. The disclosure also reports 309,136 kWh of electricity and 9,821 therms of natural gas for the year.
