Its ENERGY STAR score went from 65 in 2018 to 58 in 2024 (-7 points); its best year on file was 2023, at 84. Site EUI moved from 77.6 kBtu/ft² (2018) to 55.3 kBtu/ft² (2024), a 29% decrease. Reported emissions went from 385 tCO₂e to 247 tCO₂e over the same span (down 36%).
What does an ENERGY STAR score of 58 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 58 means the building performs better than about 58% of its national peers. BuildingCensus bands the score into report-card grades; 58 falls in band C — below median (55–69). It sits 17 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-Pao-Hv1's 55.3 kBtu/ft² across 74,374 sq ft works out to about 4.1 billion Btu (1,205 MWh-equivalent) in 2024. The disclosure also reports 780,088 kWh of electricity and 13,204 therms of natural gas for the year.
Which law requires Us-Pao-Hv1 to report its energy use?
