Insignia Condos's ENERGY STAR score of 47 compares with an average of 83 across the 1,652 that report a score; it scores higher than 7% of them and lower than 92%. Its site EUI of 47.1 kBtu/ft² is about 35% above the average of 34.9 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 0.7 kgCO₂e/ft² is roughly in line with the group average of 0.7 kgCO₂e/ft².

At 1,464,631 sq ft, it is about 1594% above the average floor area of 86,468 sq ft for those buildings. It was built in 2015, 32 years later than the group's average year built (1983). Across all 24 jurisdictions BuildingCensus covers, the 59,945 multifamily housing buildings average an ENERGY STAR score of 70 and a site EUI of 59.0 kBtu/ft².

How has Insignia Condos's energy performance changed over time?

BuildingCensus holds 9 Seattle disclosures for Insignia Condos, covering report years 2017–2025. Its ENERGY STAR score went from 98 in 2017 to 47 in 2025 (-51 points); its best year on file was 2017, at 98. Site EUI moved from 33.2 kBtu/ft² (2017) to 47.1 kBtu/ft² (2025), an 42% increase. Reported emissions went from 655 tCO₂e to 553 tCO₂e over the same span (down 16%).

What does an ENERGY STAR score of 47 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 47 means the building performs better than about 47% of its national peers. BuildingCensus bands the score into report-card grades; 47 falls in band D — lowest band (1–54). It sits 28 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. Insignia Condos's 47.1 kBtu/ft² across 1,464,631 sq ft works out to about 69 billion Btu (20,217 MWh-equivalent) in 2025. Its source EUI of 115.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 8,552,233 kWh of electricity and 72,593 therms of natural gas for the year.

Which law requires Insignia Condos to report its energy use?

Insignia Condos 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:50263:2025). 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.
