How has Montgomery Building Inc.'s energy performance changed over time?
BuildingCensus holds 15 San Francisco disclosures for Montgomery Building Inc., covering report years 2011–2025. Its ENERGY STAR score went from 85 in 2011 to 65 in 2025 (-20 points); its best year on file was 2012, at 93. Site EUI moved from 73.4 kBtu/ft² (2011) to 71.5 kBtu/ft² (2025), a 3% decrease. Reported emissions went from 987 tCO₂e to 966 tCO₂e over the same span (down 2%).
What does an ENERGY STAR score of 65 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 65 means the building performs better than about 65% of its national peers. BuildingCensus bands the score into report-card grades; 65 falls in band C — below median (55–69). It sits 10 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. Montgomery Building Inc.'s 71.5 kBtu/ft² across 245,733 sq ft works out to about 17.6 billion Btu (5,149 MWh-equivalent) in 2025. Its source EUI of 133.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,401,867 kWh of electricity and 93,681 therms of natural gas for the year.
Which law requires Montgomery Building Inc. to report its energy use?
Montgomery Building Inc. 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.
