How has The Pearl Apartments's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for The Pearl Apartments, covering report years 2015–2025. Its ENERGY STAR score went from 53 in 2015 to 81 in 2025 (+28 points); its best year on file was 2023, at 88. Site EUI moved from 44.9 kBtu/ft² (2015) to 44.9 kBtu/ft² (2025), a 0% decrease. Reported emissions went from 122 tCO₂e to 80 tCO₂e over the same span (down 35%).
What does an ENERGY STAR score of 81 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 81 means the building performs better than about 81% of its national peers. BuildingCensus bands the score into report-card grades; 81 falls in band B — above median (70–84). 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. The Pearl Apartments's 44.9 kBtu/ft² across 101,530 sq ft works out to about 4.6 billion Btu (1,336 MWh-equivalent) in 2025. Its source EUI of 95.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 609,655 kWh of electricity and 12,875 therms of natural gas for the year.
Which law requires The Pearl Apartments to report its energy use?
The Pearl Apartments 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:27926:2025). 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.
