Holgate 12's ENERGY STAR score of 100 compares with an average of 83 across the 1,652 that report a score; it scores higher than 88% of them. Its site EUI of 5.7 kBtu/ft² is about 84% below the average of 34.9 kBtu/ft² — it uses less energy per square foot than the typical building in that group.
At 23,280 sq ft, it is about 73% below the average floor area of 86,468 sq ft for those buildings. It was built in 2016, 33 years later than the group's average year built (1983). Across all 24 jurisdictions BuildingCensus covers, the 59,945 multifamily housing buildings average an ENERGY STAR score of 70 and a site EUI of 59.0 kBtu/ft².
How has Holgate 12's energy performance changed over time?
BuildingCensus holds 7 Seattle disclosures for Holgate 12, covering report years 2019–2025. Its ENERGY STAR score was 100 in both 2020 and 2025. Site EUI moved from 3.5 kBtu/ft² (2020) to 5.7 kBtu/ft² (2025), an 63% increase. Reported emissions went from 0 tCO₂e to 1 tCO₂e over the same span (up 25%).
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. Holgate 12's 5.7 kBtu/ft² across 23,280 sq ft works out to about 0.1 billion Btu (39 MWh-equivalent) in 2025. Its source EUI of 15.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 29,974 kWh of electricity for the year.
Which law requires Holgate 12 to report its energy use?
Holgate 12 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 2025 disclosure (source record seattle:50670:2025). 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.
