How has 20401 Sw Birch's energy performance changed over time?
BuildingCensus holds 2 California disclosures for 20401 Sw Birch, covering report years 2023–2024. Site EUI moved from 51.2 kBtu/ft² (2023) to 31.6 kBtu/ft² (2024), a 38% decrease. Reported emissions went from 154 tCO₂e to 100 tCO₂e over the same span (down 35%).
What does an ENERGY STAR score of 89 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 89 means the building performs better than about 89% of its national peers. BuildingCensus bands the score into report-card grades; 89 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. 20401 Sw Birch's 31.6 kBtu/ft² across 50,366 sq ft works out to about 1.6 billion Btu (466 MWh-equivalent) in 2024. The disclosure also reports 332,792 kWh of electricity and 4,558 therms of natural gas for the year.
