How has Bowles Apts's energy performance changed over time?
BuildingCensus holds 2 California disclosures for Bowles Apts, covering report years 2023–2024. Site EUI moved from 23.1 kBtu/ft² (2023) to 35.5 kBtu/ft² (2024), an 54% increase. Reported emissions went from 95 tCO₂e to 170 tCO₂e over the same span (up 79%).
What does an ENERGY STAR score of 92 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 92 means the building performs better than about 92% of its national peers. BuildingCensus bands the score into report-card grades; 92 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 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. Bowles Apts's 35.5 kBtu/ft² across 76,220 sq ft works out to about 2.7 billion Btu (793 MWh-equivalent) in 2024. The disclosure also reports 402,389 kWh of electricity and 14,783 therms of natural gas for the year.
