Its site EUI of 22.1 kBtu/ft² is about 39% below the average of 36.0 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 1.2 kgCO₂e/ft² is about 40% below the group average of 2.0 kgCO₂e/ft².
At 103,574 sq ft, it is about 37% below the average floor area of 165,572 sq ft for those buildings. Its 1968 construction date is close to the group's average year built (1967).
How has 1135 ELLIS ST's energy performance changed over time?
BuildingCensus holds 8 San Francisco disclosures for 1135 ELLIS ST, covering report years 2018–2025. Its ENERGY STAR score went from 100 in 2022 to 76 in 2025 (-24 points); its best year on file was 2022, at 100. Site EUI moved from 31.5 kBtu/ft² (2018) to 22.1 kBtu/ft² (2025), a 30% decrease. Reported emissions went from 123 tCO₂e to 125 tCO₂e over the same span (up 2%).
What does an ENERGY STAR score of 76 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 76 means the building performs better than about 76% of its national peers. BuildingCensus bands the score into report-card grades; 76 falls in band B — above median (70–84). 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. 1135 ELLIS ST's 22.1 kBtu/ft² across 103,574 sq ft works out to about 2.3 billion Btu (671 MWh-equivalent) in 2025. Its source EUI of 38.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 267,538 kWh of electricity and 13,748 therms of natural gas for the year.
Which law requires 1135 ELLIS ST to report its energy use?
1135 ELLIS 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:0735/031:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
