Its site EUI of 15.7 kBtu/ft² is about 68% 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 0.9 kgCO₂e/ft² is about 67% below the group average of 2.7 kgCO₂e/ft².
At 23,456 sq ft, it is about 78% below the average floor area of 107,408 sq ft for those buildings. It was built in 1916, 25 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 149 BLUXOME ST's energy performance changed over time?
BuildingCensus holds 15 San Francisco disclosures for 149 BLUXOME ST, covering report years 2011–2025. Its ENERGY STAR score went from 40 in 2014 to 83 in 2025 (+43 points); its best year on file was 2022, at 100. Site EUI moved from 51.6 kBtu/ft² (2014) to 15.7 kBtu/ft² (2025), a 70% decrease. Reported emissions went from 79 tCO₂e to 17 tCO₂e over the same span (down 78%).
What does an ENERGY STAR score of 83 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 83 means the building performs better than about 83% of its national peers. BuildingCensus bands the score into report-card grades; 83 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. 149 BLUXOME ST's 15.7 kBtu/ft² across 23,456 sq ft works out to about 0.4 billion Btu (108 MWh-equivalent) in 2025. Its source EUI of 44.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 88,972 kWh of electricity and 0 therms of natural gas for the year.
Which law requires 149 BLUXOME ST to report its energy use?
149 BLUXOME 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:3785/022:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
