Hill 7 Office Bldg's ENERGY STAR score of 91 compares with an average of 76 across the 378 that report a score; it scores higher than 73% of them and lower than 24%. Its site EUI of 26.2 kBtu/ft² is about 42% below the average of 44.8 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.2 kgCO₂e/ft² is about 76% below the group average of 0.7 kgCO₂e/ft².

At 431,326 sq ft, it is about twice the average floor area of 196,452 sq ft for those buildings. It was built in 2015, 50 years later than the group's average year built (1965). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².

How has Hill 7 Office Bldg's energy performance changed over time?

Its ENERGY STAR score went from 94 in 2017 to 91 in 2025 (-3 points); its best year on file was 2017, at 94. Site EUI moved from 34.0 kBtu/ft² (2017) to 26.2 kBtu/ft² (2025), a 23% decrease. Reported emissions went from 62 tCO₂e to 51 tCO₂e over the same span (down 18%).

What does an ENERGY STAR score of 91 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 91 means the building performs better than about 91% of its national peers. BuildingCensus bands the score into report-card grades; 91 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. Hill 7 Office Bldg's 26.2 kBtu/ft² across 431,326 sq ft works out to about 11.3 billion Btu (3,312 MWh-equivalent) in 2025. Its source EUI of 72.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,324,690 kWh of electricity and 903 therms of natural gas for the year.

Which law requires Hill 7 Office Bldg to report its energy use?

Hill 7 Office Bldg 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:50036:2025). 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.
