What does an ENERGY STAR score of 18 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 18 means the building performs better than about 18% of its national peers. BuildingCensus bands the score into report-card grades; 18 falls in band D — lowest band (1–54). It sits 57 points below 75, the threshold for ENERGY STAR certification. 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. Market Place North Phase I Condominium's 51.8 kBtu/ft² across 185,506 sq ft works out to about 9.6 billion Btu (2,816 MWh-equivalent) in 2025. Its source EUI of 139.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,512,555 kWh of electricity and 5,884 therms of natural gas for the year.

Which law requires Market Place North Phase I Condominium to report its energy use?

Market Place North Phase I Condominium 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:25410:2025). 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.
