How has 1810 Harrison St's energy performance changed over time?
BuildingCensus holds 15 San Francisco disclosures for 1810 Harrison St, covering report years 2011–2025. Its ENERGY STAR score went from 88 in 2013 to 99 in 2025 (+11 points). Site EUI moved from 13.2 kBtu/ft² (2013) to 2.0 kBtu/ft² (2025), a 85% decrease. Reported emissions went from 17 tCO₂e to 2 tCO₂e over the same span (down 86%).
What does an ENERGY STAR score of 99 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 99 means the building performs better than about 99% of its national peers. BuildingCensus bands the score into report-card grades; 99 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 San Francisco, 73% 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. 1810 Harrison St's 2.0 kBtu/ft² across 20,000 sq ft works out to about 0 billion Btu (12 MWh-equivalent) in 2025. Its source EUI of 5.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 11,651 kWh of electricity for the year.
Which law requires 1810 Harrison St to report its energy use?
1810 Harrison St reports under SF Environment Code Chapter 20, the legal basis of San Francisco's Existing Buildings Energy Performance Ordinance, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2025 disclosure (source record sf:3550/001:2025).
