Its site EUI of 25.5 kBtu/ft² is about half of the average of 49.2 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 56% below the group average of 2.7 kgCO₂e/ft².
At 427,914 sq ft, it is about 298% above the average floor area of 107,408 sq ft for those buildings. It was built in 2018, 77 years later than the group's average year built (1941). Across all 24 jurisdictions BuildingCensus covers, the 2,307 commercial buildings average an ENERGY STAR score of 76 and a site EUI of 51.3 kBtu/ft².
How has 100 HOOPER ST's energy performance changed over time?
BuildingCensus holds 14 San Francisco disclosures for 100 HOOPER ST, covering report years 2012–2025. Its ENERGY STAR score went from 96 in 2019 to 94 in 2025 (-2 points); its best year on file was 2023, at 100. Site EUI moved from 20.8 kBtu/ft² (2019) to 25.5 kBtu/ft² (2025), an 23% increase. Reported emissions went from 577 tCO₂e to 495 tCO₂e over the same span (down 14%).
What does an ENERGY STAR score of 94 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 94 means the building performs better than about 94% of its national peers. BuildingCensus bands the score into report-card grades; 94 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. 100 HOOPER ST's 25.5 kBtu/ft² across 427,914 sq ft works out to about 10.9 billion Btu (3,198 MWh-equivalent) in 2025. Its source EUI of 51.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,773,270 kWh of electricity and 28,136 therms of natural gas for the year.
Which law requires 100 HOOPER ST to report its energy use?
100 HOOPER 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:3808/015:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
