How has Ewa Hayward's energy performance changed over time?
BuildingCensus holds 6 California disclosures for Ewa Hayward, covering report years 2018, 2019, 2021, 2022, 2023, 2024. Its ENERGY STAR score went from 87 in 2021 to 86 in 2024 (-1 points); its best year on file was 2022, at 89. Site EUI moved from 4.9 kBtu/ft² (2021) to 5.1 kBtu/ft² (2024), an 4% increase. Reported emissions went from 15 tCO₂e to 17 tCO₂e over the same span (up 13%).
What does an ENERGY STAR score of 86 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 86 means the building performs better than about 86% of its national peers. BuildingCensus bands the score into report-card grades; 86 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. Ewa Hayward's 5.1 kBtu/ft² across 50,230 sq ft works out to about 0.3 billion Btu (75 MWh-equivalent) in 2024. The disclosure also reports 74,973 kWh of electricity for the year.
Which law requires Ewa Hayward to report its energy use?
Ewa Hayward reports under AB 802 (Public Resources Code §25402.10), the legal basis of California's Building Energy Benchmarking Program (statewide), which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2024 disclosure (source record california:12426947:2024).
