Its site EUI of 50.6 kBtu/ft² is roughly in line with the average of 49.2 kBtu/ft². Its emissions intensity of 2.8 kgCO₂e/ft² is roughly in line with the group average of 2.7 kgCO₂e/ft².
At 78,024 sq ft, it is about 27% below the average floor area of 107,408 sq ft for those buildings. Its 1942 construction date is close to 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 420 Taylor's energy performance changed over time?
BuildingCensus holds 15 San Francisco disclosures for 420 Taylor, covering report years 2011–2025. Its ENERGY STAR score went from 95 in 2011 to 60 in 2025 (-35 points); its best year on file was 2011, at 95. Site EUI moved from 49.3 kBtu/ft² (2011) to 50.6 kBtu/ft² (2025), an 3% increase. Reported emissions went from 206 tCO₂e to 220 tCO₂e over the same span (up 6%).
What does an ENERGY STAR score of 60 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 60 means the building performs better than about 60% of its national peers. BuildingCensus bands the score into report-card grades; 60 falls in band C — below median (55–69). It sits 15 points below 75, the threshold for ENERGY STAR certification. 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. 420 Taylor's 50.6 kBtu/ft² across 78,024 sq ft works out to about 3.9 billion Btu (1,157 MWh-equivalent) in 2025. Its source EUI of 106.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 700,419 kWh of electricity and 15,611 therms of natural gas for the year.
Which law requires 420 Taylor to report its energy use?
420 Taylor 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:0316/010:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
