The latest disclosures cover 497 office buildings in Seattle, out of 3,871 buildings citywide. DEPT SOCIAL & HEALTH SERVICES's ENERGY STAR score of 100 compares with an average of 76 across the 378 that report a score; it scores higher than 96% of them. Its site EUI of 8.8 kBtu/ft² is about 80% below the average of 44.8 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.1 kgCO₂e/ft² is about 93% below the group average of 0.7 kgCO₂e/ft².
At 41,262 sq ft, it is about 79% below the average floor area of 196,452 sq ft for those buildings. It was built in 1982, 17 years later than the group's average year built (1965). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².
How has DEPT SOCIAL & HEALTH SERVICES's energy performance changed over time?
BuildingCensus holds 10 Seattle disclosures for DEPT SOCIAL & HEALTH SERVICES, covering report years 2015–2024. Its ENERGY STAR score went from 86 in 2015 to 100 in 2024 (+14 points). Site EUI moved from 44.4 kBtu/ft² (2015) to 8.8 kBtu/ft² (2024), a 80% decrease. Reported emissions went from 11 tCO₂e to 2 tCO₂e over the same span (down 80%).
What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 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 Seattle, 69% 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. DEPT SOCIAL & HEALTH SERVICES's 8.8 kBtu/ft² across 41,262 sq ft works out to about 0.4 billion Btu (106 MWh-equivalent) in 2024. Its source EUI of 24.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 106,161 kWh of electricity for the year.
Which law requires DEPT SOCIAL & HEALTH SERVICES to report its energy use?
DEPT SOCIAL & HEALTH SERVICES reports under the Seattle Energy Benchmarking Ordinance (SMC 22.920), the legal basis of Seattle's Building Energy Benchmarking program, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2024 disclosure (source record seattle:21689:2024). Seattle's Building Emissions Performance Standard (adopted 2023) applies to buildings over 20,000 sq ft: benchmarking verification is due 2027–2030 and initial emissions targets 2031–2035, reaching net zero by 2041–2050, with fines for non-compliance.
