How has 670 VALENCIA ST's energy performance changed over time?

Its ENERGY STAR score went from 54 in 2022 to 93 in 2025 (+39 points). Site EUI moved from 32.9 kBtu/ft² (2022) to 26.3 kBtu/ft² (2025), a 20% decrease. Reported emissions went from 113 tCO₂e to 83 tCO₂e over the same span (down 26%).
What does an ENERGY STAR score of 93 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 93 means the building performs better than about 93% of its national peers. BuildingCensus bands the score into report-card grades; 93 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. 670 VALENCIA ST's 26.3 kBtu/ft² across 58,603 sq ft works out to about 1.5 billion Btu (452 MWh-equivalent) in 2025. Its source EUI of 38.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 102,267 kWh of electricity and 11,947 therms of natural gas for the year.
Which law requires 670 VALENCIA ST to report its energy use?
670 VALENCIA 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:3577/005:2025).
