How has 1941 Ringwood's energy performance changed over time?
BuildingCensus holds 7 California disclosures for 1941 Ringwood, covering report years 2018–2024. Its ENERGY STAR score went from 100 in 2020 to 95 in 2024 (-5 points); its best year on file was 2020, at 100. Site EUI moved from 29.2 kBtu/ft² (2018) to 27.6 kBtu/ft² (2024), a 5% decrease. Reported emissions went from 111 tCO₂e to 97 tCO₂e over the same span (down 12%).
What does an ENERGY STAR score of 95 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 95 means the building performs better than about 95% of its national peers. BuildingCensus bands the score into report-card grades; 95 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. 1941 Ringwood's 27.6 kBtu/ft² across 56,840 sq ft works out to about 1.6 billion Btu (460 MWh-equivalent) in 2024. The disclosure also reports 351,070 kWh of electricity for the year.
Which law requires 1941 Ringwood to report its energy use?
