How does 744 N 34th St compare with other office buildings in Seattle?
The latest disclosures cover 497 office buildings in Seattle, out of 3,871 buildings citywide. 744 N 34th St's ENERGY STAR score of 65 compares with an average of 76 across the 378 that report a score; it scores higher than 20% of them and lower than 79%. Its site EUI of 58.9 kBtu/ft² is about 31% above the average of 44.8 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 0.4 kgCO₂e/ft² is about 39% below the group average of 0.7 kgCO₂e/ft².
At 202,081 sq ft, it is roughly in line with the average floor area of 196,452 sq ft for those buildings. It was built in 2017, 52 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 744 N 34th St's energy performance changed over time?
BuildingCensus holds 8 Seattle disclosures for 744 N 34th St, covering report years 2018–2025. Its ENERGY STAR score went from 61 in 2024 to 65 in 2025 (+4 points). Site EUI moved from 51.8 kBtu/ft² (2018) to 58.9 kBtu/ft² (2025), an 14% increase. Reported emissions went from 69 tCO₂e to 56 tCO₂e over the same span (down 19%).
What does an ENERGY STAR score of 65 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 65 means the building performs better than about 65% of its national peers. BuildingCensus bands the score into report-card grades; 65 falls in band C — below median (55–69). It sits 10 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. 744 N 34th St's 58.9 kBtu/ft² across 202,081 sq ft works out to about 11.9 billion Btu (3,488 MWh-equivalent) in 2025. Its source EUI of 161.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,164,893 kWh of electricity and 2,442 therms of natural gas for the year.
Which law requires 744 N 34th St to report its energy use?
744 N 34th St 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:50130:2025). 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.
