How does 541 8TH ST compare with other commercial buildings in San Francisco?

The latest disclosures cover 1,683 commercial buildings in San Francisco, out of 2,509 buildings citywide. 541 8TH ST's ENERGY STAR score of 85 compares with an average of 78 across the 790 that report a score; it scores higher than 48% of them and lower than 50%. Its site EUI of 17.7 kBtu/ft² is about 64% below 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 1.0 kgCO₂e/ft² is about 63% below the group average of 2.7 kgCO₂e/ft².

At 13,824 sq ft, it is about 87% below the average floor area of 107,408 sq ft for those buildings. It was built in 1937, 4 years earlier 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 541 8TH ST's energy performance changed over time?

BuildingCensus holds 15 San Francisco disclosures for 541 8TH ST, covering report years 2011–2025. Its ENERGY STAR score went from 97 in 2015 to 85 in 2025 (-12 points); its best year on file was 2015, at 97. Site EUI moved from 27.0 kBtu/ft² (2015) to 17.7 kBtu/ft² (2025), a 34% decrease. Reported emissions went from 28 tCO₂e to 14 tCO₂e over the same span (down 50%).

What does an ENERGY STAR score of 85 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 85 means the building performs better than about 85% of its national peers. BuildingCensus bands the score into report-card grades; 85 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. 541 8TH ST's 17.7 kBtu/ft² across 13,824 sq ft works out to about 0.2 billion Btu (72 MWh-equivalent) in 2025. Its source EUI of 49.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 71,692 kWh of electricity and 1 therms of natural gas for the year.

Which law requires 541 8TH ST to report its energy use?

541 8TH 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:3780/008:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
