How has Lakewood Apartments's energy performance changed over time?
BuildingCensus holds 8 San Francisco disclosures for Lakewood Apartments, covering report years 2018–2025. Its ENERGY STAR score went from 81 in 2019 to 96 in 2025 (+15 points); its best year on file was 2022, at 100. Site EUI moved from 24.7 kBtu/ft² (2019) to 26.3 kBtu/ft² (2025), an 6% increase. Reported emissions went from 1,247 tCO₂e to 1,227 tCO₂e over the same span (down 2%).
What does an ENERGY STAR score of 96 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 96 means the building performs better than about 96% of its national peers. BuildingCensus bands the score into report-card grades; 96 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. Lakewood Apartments's 26.3 kBtu/ft² across 853,363 sq ft works out to about 22.4 billion Btu (6,578 MWh-equivalent) in 2025. Its source EUI of 46.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,632,204 kWh of electricity and 134,437 therms of natural gas for the year.
Which law requires Lakewood Apartments to report its energy use?
