Its ENERGY STAR score went from 78 in 2011 to 74 in 2025 (-4 points); its best year on file was 2016, at 95. Site EUI moved from 61.8 kBtu/ft² (2011) to 40.0 kBtu/ft² (2025), a 35% decrease. Reported emissions went from 238 tCO₂e to 116 tCO₂e over the same span (down 51%).

What does an ENERGY STAR score of 74 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 74 means the building performs better than about 74% of its national peers. BuildingCensus bands the score into report-card grades; 74 falls in band B — above median (70–84). It sits 1 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. C&W Sakti 260 California's 40.0 kBtu/ft² across 52,889 sq ft works out to about 2.1 billion Btu (620 MWh-equivalent) in 2025. Its source EUI of 72.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 266,816 kWh of electricity and 12,043 therms of natural gas for the year.

Which law requires C&W Sakti 260 California to report its energy use?

C&W Sakti 260 California 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:0237/011:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
