How has 1890 CLAY ST's energy performance changed over time?
BuildingCensus holds 8 San Francisco disclosures for 1890 CLAY ST, covering report years 2018–2025. Its ENERGY STAR score went from 96 in 2019 to 100 in 2025 (+4 points). Site EUI moved from 32.4 kBtu/ft² (2019) to 28.6 kBtu/ft² (2025), a 12% decrease. Reported emissions went from 137 tCO₂e to 105 tCO₂e over the same span (down 23%).
What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 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. 1890 CLAY ST's 28.6 kBtu/ft² across 91,765 sq ft works out to about 2.6 billion Btu (769 MWh-equivalent) in 2025. Its source EUI of 58.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 317,013 kWh of electricity and 8,116 therms of natural gas for the year.
Which law requires 1890 CLAY ST to report its energy use?
1890 CLAY 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:0618/004:2025).
