Its ENERGY STAR score went from 42 in 2011 to 56 in 2025 (+14 points); its best year on file was 2022, at 83. Site EUI moved from 74.7 kBtu/ft² (2011) to 45.5 kBtu/ft² (2025), a 39% decrease. Reported emissions went from 418 tCO₂e to 181 tCO₂e over the same span (down 57%).
What does an ENERGY STAR score of 56 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 56 means the building performs better than about 56% of its national peers. BuildingCensus bands the score into report-card grades; 56 falls in band C — below median (55–69). It sits 19 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. Young Chi Shing, Inc.'s 45.5 kBtu/ft² across 64,800 sq ft works out to about 2.9 billion Btu (864 MWh-equivalent) in 2025. Its source EUI of 95.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 478,636 kWh of electricity for the year.
Which law requires Young Chi Shing, Inc. to report its energy use?
Young Chi Shing, 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.
