How does Heartwood/Fobes 562 compare with other office buildings in Seattle?
The latest disclosures cover 497 office buildings in Seattle, out of 3,871 buildings citywide. Heartwood/Fobes 562's ENERGY STAR score of 93 compares with an average of 76 across the 378 that report a score; it scores higher than 79% of them and lower than 19%. Its site EUI of 15.6 kBtu/ft² is about 65% 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 0.1 kgCO₂e/ft² is about 86% below the group average of 0.7 kgCO₂e/ft².
At 36,000 sq ft, it is about 82% below the average floor area of 196,452 sq ft for those buildings. It was built in 1909, 56 years earlier 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 Heartwood/Fobes 562's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Heartwood/Fobes 562, covering report years 2015–2025. Its ENERGY STAR score went from 47 in 2015 to 93 in 2025 (+46 points). Site EUI moved from 48.4 kBtu/ft² (2015) to 15.6 kBtu/ft² (2025), a 68% decrease. Reported emissions went from 9 tCO₂e to 3 tCO₂e over the same span (down 63%).
What does an ENERGY STAR score of 93 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 93 means the building performs better than about 93% of its national peers. BuildingCensus bands the score into report-card grades; 93 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. Heartwood/Fobes 562's 15.6 kBtu/ft² across 36,000 sq ft works out to about 0.6 billion Btu (165 MWh-equivalent) in 2025. Its source EUI of 43.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 165,101 kWh of electricity for the year.
Which law requires Heartwood/Fobes 562 to report its energy use?
Heartwood/Fobes 562 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:24712:2025). 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.
