How does 175 BLUXOME ST compare with other mixed residential buildings in San Francisco?
The latest disclosures cover 610 mixed residential buildings in San Francisco, out of 2,509 buildings citywide. 175 BLUXOME ST's ENERGY STAR score of 96 compares with an average of 85 across the 340 that report a score; it scores higher than 48% of them and lower than 47%. Its site EUI of 18.2 kBtu/ft² is about half of the average of 36.0 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 1.0 kgCO₂e/ft² is about half of the group average of 2.0 kgCO₂e/ft².
At 135,229 sq ft, it is about 18% below the average floor area of 165,572 sq ft for those buildings. It was built in 1998, 32 years later than the group's average year built (1967).
How has 175 BLUXOME ST's energy performance changed over time?
BuildingCensus holds 8 San Francisco disclosures for 175 BLUXOME ST, covering report years 2018–2025. Its ENERGY STAR score went from 97 in 2023 to 96 in 2025 (-1 points); its best year on file was 2023, at 97. Site EUI moved from 18.5 kBtu/ft² (2023) to 18.2 kBtu/ft² (2025), a 2% decrease. Reported emissions went from 153 tCO₂e to 137 tCO₂e over the same span (down 11%).
What does an ENERGY STAR score of 96 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 96 means the building performs better than about 96% of its national peers. BuildingCensus bands the score into report-card grades; 96 falls in band A — high performer (85–100). 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. 175 BLUXOME ST's 18.2 kBtu/ft² across 135,229 sq ft works out to about 2.5 billion Btu (721 MWh-equivalent) in 2025. Its source EUI of 38.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 432,139 kWh of electricity and 9,840 therms of natural gas for the year.
Which law requires 175 BLUXOME ST to report its energy use?
175 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.
