Its site EUI of 52.5 kBtu/ft² is about 46% above the average of 36.0 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 2.9 kgCO₂e/ft² is about 44% above the group average of 2.0 kgCO₂e/ft².

At 109,817 sq ft, it is about 34% below the average floor area of 165,572 sq ft for those buildings. It was built in 2016, 50 years later than the group's average year built (1967).

How has 1401 MISSION ST's energy performance changed over time?

BuildingCensus holds 8 San Francisco disclosures for 1401 MISSION ST, covering report years 2018–2025. Its ENERGY STAR score went from 96 in 2018 to 53 in 2025 (-43 points); its best year on file was 2022, at 100. Site EUI moved from 29.1 kBtu/ft² (2018) to 52.5 kBtu/ft² (2025), an 80% increase. Reported emissions went from 228 tCO₂e to 232 tCO₂e over the same span (up 2%).

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. 1401 MISSION ST's 52.5 kBtu/ft² across 109,817 sq ft works out to about 5.8 billion Btu (1,690 MWh-equivalent) in 2025. Its source EUI of 94.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 529,435 kWh of electricity and 24,195 therms of natural gas for the year.

Which law requires 1401 MISSION ST to report its energy use?

1401 MISSION 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:3510/001:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
