How has CPMC PACIFIC CAMPUS - ANNEX BUILDING's energy performance changed over time?
BuildingCensus holds 14 San Francisco disclosures for CPMC PACIFIC CAMPUS - ANNEX BUILDING, covering report years 2012–2025. Its ENERGY STAR score was 100 in both 2023 and 2025.

What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 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 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. CPMC PACIFIC CAMPUS - ANNEX BUILDING's 15.1 kBtu/ft² across 67,948 sq ft works out to about 1 billion Btu (301 MWh-equivalent) in 2025. Its source EUI of 42.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 300,203 kWh of electricity for the year.
