How does 450 Pacific KYL 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. 450 Pacific KYL's ENERGY STAR score of 53 compares with an average of 78 across the 790 that report a score; it scores higher than 13% of them and lower than 86%. Its site EUI of 46.8 kBtu/ft² is roughly in line with 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 2.6 kgCO₂e/ft² is roughly in line with the group average of 2.7 kgCO₂e/ft².
At 26,476 sq ft, it is about 75% below the average floor area of 107,408 sq ft for those buildings. It was built in 1906, 35 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 450 Pacific KYL's energy performance changed over time?
BuildingCensus holds 15 San Francisco disclosures for 450 Pacific KYL, covering report years 2011–2025. Its ENERGY STAR score went from 55 in 2012 to 53 in 2025 (-2 points); its best year on file was 2024, at 74. Site EUI moved from 65.2 kBtu/ft² (2012) to 46.8 kBtu/ft² (2025), a 28% decrease. Reported emissions went from 123 tCO₂e to 69 tCO₂e over the same span (down 44%).
What does an ENERGY STAR score of 53 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 53 means the building performs better than about 53% of its national peers. BuildingCensus bands the score into report-card grades; 53 falls in band D — lowest band (1–54). It sits 22 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. 450 Pacific KYL's 46.8 kBtu/ft² across 26,476 sq ft works out to about 1.2 billion Btu (363 MWh-equivalent) in 2025. Its source EUI of 97.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 214,162 kWh of electricity and 5,076 therms of natural gas for the year.
Which law requires 450 Pacific KYL to report its energy use?
450 Pacific KYL 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:0164/010:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
