The Ivey on Boren

How does The Ivey on Boren compare with other buildings in Seattle?

The latest disclosures cover 3,871 benchmarked buildings in Seattle. The Ivey on Boren's ENERGY STAR score of 77 compares with an average of 78 across the 2,721 that report a score. Its site EUI of 27.1 kBtu/ft² is about 43% below the average of 47.6 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.6 kgCO₂e/ft² is about 36% below the group average of 1.0 kgCO₂e/ft².

At 632,270 sq ft, it is about 462% above the average floor area of 112,467 sq ft for those buildings. It was built in 2021, 46 years later than the group's average year built (1975). Across all 24 jurisdictions BuildingCensus covers, the 4 multifamily HR (10+) buildings average an ENERGY STAR score of 65 and a site EUI of 37.9 kBtu/ft².

How has The Ivey on Boren's energy performance changed over time?

BuildingCensus holds 2 Seattle disclosures for The Ivey on Boren, covering report years 2023–2024. Its ENERGY STAR score went from 78 in 2023 to 77 in 2024 (-1 points); its best year on file was 2023, at 78. Site EUI moved from 27.8 kBtu/ft² (2023) to 27.1 kBtu/ft² (2024), a 3% decrease. Reported emissions went from 429 tCO₂e to 410 tCO₂e over the same span (down 5%).

What does an ENERGY STAR score of 77 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 77 means the building performs better than about 77% of its national peers. BuildingCensus bands the score into report-card grades; 77 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 Ivey on Boren's 27.1 kBtu/ft² across 632,270 sq ft works out to about 17.1 billion Btu (5,022 MWh-equivalent) in 2024. Its source EUI of 58.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,190,657 kWh of electricity and 65,448 therms of natural gas for the year.

Which law requires The Ivey on Boren to report its energy use?

The Ivey on Boren 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 2024 disclosure (source record seattle:50942:2024). 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.
