Angeline Apts's ENERGY STAR score of 98 compares with an average of 83 across the 1,652 that report a score; it scores higher than 75% of them and lower than 20%. Its site EUI of 42.7 kBtu/ft² is about 22% above the average of 34.9 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 1.4 kgCO₂e/ft² is about twice the group average of 0.7 kgCO₂e/ft².
At 283,479 sq ft, it is about 228% above the average floor area of 86,468 sq ft for those buildings. It was built in 2015, 32 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 Angeline Apts's energy performance changed over time?
BuildingCensus holds 10 Seattle disclosures for Angeline Apts, covering report years 2016–2025. Its ENERGY STAR score went from 100 in 2016 to 98 in 2025 (-2 points); its best year on file was 2016, at 100. Site EUI moved from 41.1 kBtu/ft² (2016) to 42.7 kBtu/ft² (2025), an 4% increase. Reported emissions went from 235 tCO₂e to 227 tCO₂e over the same span (down 3%).
What does an ENERGY STAR score of 98 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 98 means the building performs better than about 98% of its national peers. BuildingCensus bands the score into report-card grades; 98 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. Angeline Apts's 42.7 kBtu/ft² across 283,479 sq ft works out to about 12.1 billion Btu (3,547 MWh-equivalent) in 2025. Its source EUI of 78.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 942,329 kWh of electricity and 39,364 therms of natural gas for the year.
Which law requires Angeline Apts to report its energy use?
Angeline Apts 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:50030:2025). 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.
