How has Lee And Lee Apartments's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Lee And Lee Apartments, covering report years 2015–2025. Its ENERGY STAR score went from 91 in 2015 to 100 in 2025 (+9 points). Site EUI moved from 30.6 kBtu/ft² (2015) to 22.9 kBtu/ft² (2025), a 25% decrease. Reported emissions went from 4 tCO₂e to 3 tCO₂e over the same span (down 27%).
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. Lee And Lee Apartments's 22.9 kBtu/ft² across 24,548 sq ft works out to about 0.6 billion Btu (165 MWh-equivalent) in 2025. Its source EUI of 64.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 164,654 kWh of electricity for the year.
Which law requires Lee And Lee Apartments to report its energy use?
Lee And Lee 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.
