How has Springbrook Grove's energy performance changed over time?
BuildingCensus holds 3 California disclosures for Springbrook Grove, covering report years 2021–2023. Its ENERGY STAR score was 100 in both 2021 and 2023. Site EUI moved from 18.3 kBtu/ft² (2021) to 18.9 kBtu/ft² (2023), an 3% increase. Reported emissions went from 80 tCO₂e to 87 tCO₂e over the same span (up 8%).
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. Springbrook Grove's 18.9 kBtu/ft² across 77,101 sq ft works out to about 1.5 billion Btu (427 MWh-equivalent) in 2023. The disclosure also reports 149,865 kWh of electricity and 9,475 therms of natural gas for the year.
