How has 1901 Harrison's energy performance changed over time?
BuildingCensus holds 5 California disclosures for 1901 Harrison, covering report years 2019–2023. Its ENERGY STAR score went from 74 in 2019 to 96 in 2023 (+22 points); its best year on file was 2022, at 98. Site EUI moved from 53.5 kBtu/ft² (2019) to 26.3 kBtu/ft² (2023), a 51% decrease. Reported emissions went from 936 tCO₂e to 572 tCO₂e over the same span (down 39%).
What does an ENERGY STAR score of 96 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 96 means the building performs better than about 96% of its national peers. BuildingCensus bands the score into report-card grades; 96 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. 1901 Harrison's 26.3 kBtu/ft² across 341,190 sq ft works out to about 9 billion Btu (2,630 MWh-equivalent) in 2023. The disclosure also reports 1,472,246 kWh of electricity and 40,529 therms of natural gas for the year.
