NEMS - Stockton's ENERGY STAR score of 28 compares with an average of 78 across the 790 that report a score; it scores higher than 5% of them and lower than 95%. Its site EUI of 111.4 kBtu/ft² is about 126% above the average of 49.2 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 6.2 kgCO₂e/ft² is about 130% above the group average of 2.7 kgCO₂e/ft².
At 46,470 sq ft, it is about 57% below the average floor area of 107,408 sq ft for those buildings. It was built in 1926, 15 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 NEMS - Stockton's energy performance changed over time?
BuildingCensus holds 15 San Francisco disclosures for NEMS - Stockton, covering report years 2011–2025. Its ENERGY STAR score went from 13 in 2012 to 28 in 2025 (+15 points); its best year on file was 2024, at 30. Site EUI moved from 120.7 kBtu/ft² (2012) to 111.4 kBtu/ft² (2025), a 8% decrease. Reported emissions went from 395 tCO₂e to 288 tCO₂e over the same span (down 27%).
What does an ENERGY STAR score of 28 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 28 means the building performs better than about 28% of its national peers. BuildingCensus bands the score into report-card grades; 28 falls in band D — lowest band (1–54). It sits 47 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. NEMS - Stockton's 111.4 kBtu/ft² across 46,470 sq ft works out to about 5.2 billion Btu (1,517 MWh-equivalent) in 2025. Its source EUI of 241.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 972,320 kWh of electricity and 18,594 therms of natural gas for the year.
Which law requires NEMS - Stockton to report its energy use?
NEMS - Stockton 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:0116/020B: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.
