How has Hatch Elementary School's energy performance changed over time?
BuildingCensus holds 2 California disclosures for Hatch Elementary School, covering report years 2023–2024. Its ENERGY STAR score was 100 in both 2023 and 2024. Site EUI moved from 13.8 kBtu/ft² (2023) to 15.8 kBtu/ft² (2024), an 14% increase. Reported emissions went from 59 tCO₂e to 67 tCO₂e over the same span (up 14%).
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 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. Hatch Elementary School's 15.8 kBtu/ft² across 71,246 sq ft works out to about 1.1 billion Btu (330 MWh-equivalent) in 2024. The disclosure also reports 70,659 kWh of electricity and 5,743 therms of natural gas for the year.
Which law requires Hatch Elementary School to report its energy use?
