Its site EUI of 49.3 kBtu/ft² is roughly in line with the average of 49.2 kBtu/ft². Its emissions intensity of 2.7 kgCO₂e/ft² is roughly in line with the group average of 2.7 kgCO₂e/ft².
At 375,233 sq ft, it is about 249% above the average floor area of 107,408 sq ft for those buildings. It was built in 1986, 45 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 505 Montgomery's energy performance changed over time?
BuildingCensus holds 15 San Francisco disclosures for 505 Montgomery, covering report years 2011–2025. Its ENERGY STAR score went from 84 in 2011 to 76 in 2025 (-8 points); its best year on file was 2017, at 89. Site EUI moved from 55.8 kBtu/ft² (2011) to 49.3 kBtu/ft² (2025), a 12% decrease. Reported emissions went from 1,641 tCO₂e to 991 tCO₂e over the same span (down 40%).
What does an ENERGY STAR score of 76 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 76 means the building performs better than about 76% of its national peers. BuildingCensus bands the score into report-card grades; 76 falls in band B — above median (70–84). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. 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. 505 Montgomery's 49.3 kBtu/ft² across 375,233 sq ft works out to about 18.5 billion Btu (5,422 MWh-equivalent) in 2025. Its source EUI of 92.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,488,585 kWh of electricity and 95,129 therms of natural gas for the year.
Which law requires 505 Montgomery to report its energy use?
505 Montgomery 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:0227/005:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
