How does 80 Carolina 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. 80 Carolina's ENERGY STAR score of 69 compares with an average of 78 across the 790 that report a score; it scores higher than 24% of them and lower than 75%. Its site EUI of 20.6 kBtu/ft² is about 58% 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 1.2 kgCO₂e/ft² is about 57% below the group average of 2.7 kgCO₂e/ft².
At 24,000 sq ft, it is about 78% below the average floor area of 107,408 sq ft for those buildings. It was built in 1984, 43 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 80 Carolina's energy performance changed over time?
BuildingCensus holds 15 San Francisco disclosures for 80 Carolina, covering report years 2011–2025. Its ENERGY STAR score went from 98 in 2018 to 69 in 2025 (-29 points); its best year on file was 2018, at 98. Site EUI moved from 19.9 kBtu/ft² (2017) to 20.6 kBtu/ft² (2025), an 4% increase. Reported emissions went from 30 tCO₂e to 28 tCO₂e over the same span (down 7%).
What does an ENERGY STAR score of 69 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 69 means the building performs better than about 69% of its national peers. BuildingCensus bands the score into report-card grades; 69 falls in band C — below median (55–69). It sits 6 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. 80 Carolina's 20.6 kBtu/ft² across 24,000 sq ft works out to about 0.5 billion Btu (145 MWh-equivalent) in 2025. Its source EUI of 57.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 144,580 kWh of electricity and 0 therms of natural gas for the year.
Which law requires 80 Carolina to report its energy use?
80 Carolina 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:3913/002:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
