Its ENERGY STAR score went from 95 in 2024 to 92 in 2025 (-3 points); its best year on file was 2024, at 95. Site EUI moved from 53.1 kBtu/ft² (2024) to 55.6 kBtu/ft² (2025), an 5% increase. Reported emissions went from 106 tCO₂e to 107 tCO₂e over the same span (up 1%).

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 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. Aegis Of Greenwood's 55.6 kBtu/ft² across 114,476 sq ft works out to about 6.4 billion Btu (1,865 MWh-equivalent) in 2025. Its source EUI of 123.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 972,220 kWh of electricity and 16,625 therms of natural gas for the year.

Which law requires Aegis Of Greenwood to report its energy use?

Aegis Of Greenwood 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:50926:2025). 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.
