How has Us-Mtv-Frc2's energy performance changed over time?
BuildingCensus holds 7 California disclosures for Us-Mtv-Frc2, covering report years 2018–2024. Its ENERGY STAR score went from 32 in 2018 to 48 in 2024 (+16 points); its best year on file was 2021, at 71. Site EUI moved from 111.9 kBtu/ft² (2018) to 100.3 kBtu/ft² (2024), a 10% decrease. Reported emissions went from 451 tCO₂e to 369 tCO₂e over the same span (down 18%).
What does an ENERGY STAR score of 48 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 48 means the building performs better than about 48% of its national peers. BuildingCensus bands the score into report-card grades; 48 falls in band D — lowest band (1–54). It sits 27 points below 75, the threshold for ENERGY STAR certification. 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-Mtv-Frc2's 100.3 kBtu/ft² across 64,474 sq ft works out to about 6.5 billion Btu (1,895 MWh-equivalent) in 2024. The disclosure also reports 960,350 kWh of electricity and 28,545 therms of natural gas for the year.
