How has Winton Properties's energy performance changed over time?
BuildingCensus holds 15 San Francisco disclosures for Winton Properties, covering report years 2011–2025. Its ENERGY STAR score was 100 in both 2013 and 2022. Site EUI moved from 21.6 kBtu/ft² (2013) to 7.6 kBtu/ft² (2025), a 65% decrease. Reported emissions went from 37 tCO₂e to 10 tCO₂e over the same span (down 73%).
What does a site EUI of 7.6 kBtu/ft² mean?
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. Winton Properties's 7.6 kBtu/ft² across 27,667 sq ft works out to about 0.2 billion Btu (62 MWh-equivalent) in 2025. Its source EUI of 13.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 21,284 kWh of electricity and 1,079 therms of natural gas for the year.
Which law requires Winton Properties to report its energy use?
Winton Properties 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:3956/004:2025).
