How has 88 KING ST's energy performance changed over time?
BuildingCensus holds 8 San Francisco disclosures for 88 KING ST, covering report years 2018–2025. Only one of those years carries energy figures.
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. 88 KING ST's 21.6 kBtu/ft² across 425,340 sq ft works out to about 9.2 billion Btu (2,693 MWh-equivalent) in 2025. Its source EUI of 37.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,078,557 kWh of electricity and 54,887 therms of natural gas for the year.
Which law requires 88 KING ST to report its energy use?
88 KING 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:3793/005:2025).
