At 112,292 sq ft, it is about 32% below the average floor area of 165,572 sq ft for those buildings. It was built in 1950, 16 years earlier than the group's average year built (1967).
How has 1000 GREEN ST's energy performance changed over time?
BuildingCensus holds 8 San Francisco disclosures for 1000 GREEN ST, covering report years 2018–2025. Its ENERGY STAR score went from 48 in 2023 to 58 in 2025 (+10 points); its best year on file was 2024, at 60. Site EUI moved from 64.8 kBtu/ft² (2023) to 57.8 kBtu/ft² (2025), a 11% decrease. Reported emissions went from 338 tCO₂e to 301 tCO₂e over the same span (down 11%).
What does an ENERGY STAR score of 58 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 58 means the building performs better than about 58% of its national peers. BuildingCensus bands the score into report-card grades; 58 falls in band C — below median (55–69). It sits 17 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. 1000 GREEN ST's 57.8 kBtu/ft² across 112,292 sq ft works out to about 6.5 billion Btu (1,902 MWh-equivalent) in 2025. Its source EUI of 78.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 284,775 kWh of electricity and 46,273 therms of natural gas for the year.
Which law requires 1000 GREEN ST to report its energy use?
1000 GREEN 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:0121/004:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
