How has Us-Svl-Tc6's energy performance changed over time?
BuildingCensus holds 5 California disclosures for Us-Svl-Tc6, covering report years 2018, 2019, 2020, 2021, 2023. Its ENERGY STAR score went from 76 in 2018 to 92 in 2023 (+16 points). Site EUI moved from 44.7 kBtu/ft² (2018) to 40.1 kBtu/ft² (2023), a 10% decrease. Reported emissions went from 841 tCO₂e to 593 tCO₂e over the same span (down 30%).
What does an ENERGY STAR score of 92 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 92 means the building performs better than about 92% of its national peers. BuildingCensus bands the score into report-card grades; 92 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. Us-Svl-Tc6's 40.1 kBtu/ft² across 214,343 sq ft works out to about 8.6 billion Btu (2,519 MWh-equivalent) in 2023. The disclosure also reports 2,026,611 kWh of electricity and 19,245 therms of natural gas for the year.
