How has Piedmont Avenue Apartments's energy performance changed over time?
BuildingCensus holds 4 Berkeley disclosures for Piedmont Avenue Apartments, covering report years 2022–2025. Its ENERGY STAR score went from 100 in 2022 to 99 in 2025 (-1 points); its best year on file was 2022, at 100. Site EUI moved from 25.4 kBtu/ft² (2022) to 24.0 kBtu/ft² (2025), a 6% decrease.
What does an ENERGY STAR score of 99 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 99 means the building performs better than about 99% of its national peers. BuildingCensus bands the score into report-card grades; 99 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 Berkeley, 82% 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. Piedmont Avenue Apartments's 24.0 kBtu/ft² across 28,626 sq ft works out to about 0.7 billion Btu (201 MWh-equivalent) in 2025. Its source EUI of 45.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 99,003 kWh of electricity and 3,483 therms of natural gas for the year.
Which law requires Piedmont Avenue Apartments to report its energy use?
