What does an ENERGY STAR score of 72 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 72 means the building performs better than about 72% of its national peers. BuildingCensus bands the score into report-card grades; 72 falls in band B — above median (70–84). It sits 3 points below 75, the threshold for ENERGY STAR certification. In San Francisco, 73% 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. Sister Lillian Murphy Community's 54.2 kBtu/ft² across 122,092 sq ft works out to about 6.6 billion Btu (1,939 MWh-equivalent) in 2025. Its source EUI of 97.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 823,739 kWh of electricity and 38,104 therms of natural gas for the year.
