At 242,926 sq ft, it is about 27% above the average floor area of 191,699 sq ft for those buildings. Across all 24 jurisdictions BuildingCensus covers, the 238 multifamily buildings average an ENERGY STAR score of 86 and a site EUI of 34.8 kBtu/ft².
How has Sunnydale Block 6's energy performance changed over time?
BuildingCensus holds 4 San Francisco disclosures for Sunnydale Block 6, covering report years 2022–2025. Its ENERGY STAR score went from 69 in 2022 to 92 in 2025 (+23 points). Site EUI moved from 42.5 kBtu/ft² (2022) to 32.8 kBtu/ft² (2025), a 23% decrease. Reported emissions went from 631 tCO₂e to 441 tCO₂e over the same span (down 30%).
What does an ENERGY STAR score of 92 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 92 means the building performs better than about 92% of its national peers. BuildingCensus bands the score into report-card grades; 92 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. Sunnydale Block 6's 32.8 kBtu/ft² across 242,926 sq ft works out to about 8 billion Btu (2,335 MWh-equivalent) in 2025. Its source EUI of 65.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,245,037 kWh of electricity and 37,219 therms of natural gas for the year.
Which law requires Sunnydale Block 6 to report its energy use?
Sunnydale Block 6 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:6312/010:2025).
