How has Avalon Hayes Valley's energy performance changed over time?
BuildingCensus holds 8 San Francisco disclosures for Avalon Hayes Valley, covering report years 2018–2025. Its ENERGY STAR score went from 96 in 2018 to 86 in 2025 (-10 points); its best year on file was 2019, at 97. Site EUI moved from 25.1 kBtu/ft² (2018) to 27.6 kBtu/ft² (2025), an 10% increase. Reported emissions went from 132 tCO₂e to 263 tCO₂e over the same span (up 99%).
What does an ENERGY STAR score of 86 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 86 means the building performs better than about 86% of its national peers. BuildingCensus bands the score into report-card grades; 86 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. Avalon Hayes Valley's 27.6 kBtu/ft² across 172,276 sq ft works out to about 4.8 billion Btu (1,394 MWh-equivalent) in 2025. Its source EUI of 56.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 781,413 kWh of electricity and 20,859 therms of natural gas for the year.
Which law requires Avalon Hayes Valley to report its energy use?
Avalon Hayes Valley 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:0831/023:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
