How has 318 SPEAR ST's energy performance changed over time?
BuildingCensus holds 8 San Francisco disclosures for 318 SPEAR ST, covering report years 2018–2025. Its ENERGY STAR score was 98 in both 2022 and 2025. Site EUI moved from 20.5 kBtu/ft² (2021) to 21.4 kBtu/ft² (2025), an 4% increase. Reported emissions went from 1,744 tCO₂e to 1,769 tCO₂e over the same span (up 1%).
What does an ENERGY STAR score of 98 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 98 means the building performs better than about 98% of its national peers. BuildingCensus bands the score into report-card grades; 98 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. 318 SPEAR ST's 21.4 kBtu/ft² across 1,500,000 sq ft works out to about 32.1 billion Btu (9,408 MWh-equivalent) in 2025. Its source EUI of 40.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 4,434,281 kWh of electricity and 170,254 therms of natural gas for the year.
Which law requires 318 SPEAR ST to report its energy use?
318 SPEAR 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:3745/012:2025).
