Its site EUI of 47.0 kBtu/ft² is roughly in line with 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 2.7 kgCO₂e/ft² is roughly in line with the group average of 2.7 kgCO₂e/ft².
At 10,367 sq ft, it is about 90% below the average floor area of 107,408 sq ft for those buildings. 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 98 W PORTAL AVE's energy performance changed over time?
BuildingCensus holds 14 San Francisco disclosures for 98 W PORTAL AVE, covering report years 2012–2025. Its ENERGY STAR score went from 87 in 2019 to 73 in 2025 (-14 points); its best year on file was 2019, at 87. Site EUI moved from 37.7 kBtu/ft² (2019) to 47.0 kBtu/ft² (2025), an 25% increase. Reported emissions went from 28 tCO₂e to 28 tCO₂e over the same span (up 1%).
What does an ENERGY STAR score of 73 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 73 means the building performs better than about 73% of its national peers. BuildingCensus bands the score into report-card grades; 73 falls in band B — above median (70–84). It sits 2 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. 98 W PORTAL AVE's 47.0 kBtu/ft² across 10,367 sq ft works out to about 0.5 billion Btu (143 MWh-equivalent) in 2025. Its source EUI of 131.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 142,721 kWh of electricity for the year.
Which law requires 98 W PORTAL AVE to report its energy use?
98 W PORTAL AVE 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:2931/009A: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.
