What does an ENERGY STAR score of 61 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 61 means the building performs better than about 61% of its national peers. BuildingCensus bands the score into report-card grades; 61 falls in band C — below median (55–69). It sits 14 points below 75, the threshold for ENERGY STAR certification. 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. Pacifica Senior Living Union City's 104.6 kBtu/ft² across 20,000 sq ft works out to about 2.1 billion Btu (613 MWh-equivalent) in 2023. The disclosure also reports 321,839 kWh of electricity and 10,361 therms of natural gas for the year.
