How has 1256 MARKET ST's energy performance changed over time?
BuildingCensus holds 15 San Francisco disclosures for 1256 MARKET ST, covering report years 2011–2025. Its ENERGY STAR score went from 99 in 2015 to 100 in 2025 (+1 points); its best year on file was 2023, at 100. Site EUI moved from 15.9 kBtu/ft² (2015) to 12.0 kBtu/ft² (2025), a 25% decrease. Reported emissions went from 39 tCO₂e to 20 tCO₂e over the same span (down 47%).
What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 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. 1256 MARKET ST's 12.0 kBtu/ft² across 29,604 sq ft works out to about 0.4 billion Btu (104 MWh-equivalent) in 2025. Its source EUI of 33.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 103,934 kWh of electricity and 1 therms of natural gas for the year.
Which law requires 1256 MARKET ST to report its energy use?
1256 MARKET 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:0355/008:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
