How has Infinity Shore Club's energy performance changed over time?
BuildingCensus holds 3 Seattle disclosures for Infinity Shore Club, covering report years 2023–2025. Its ENERGY STAR score went from 65 in 2024 to 60 in 2025 (-5 points); its best year on file was 2024, at 65. Site EUI moved from 53.7 kBtu/ft² (2024) to 54.8 kBtu/ft² (2025), an 2% increase. Reported emissions went from 7 tCO₂e to 80 tCO₂e over the same span (up 1032%).
What does an ENERGY STAR score of 60 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 60 means the building performs better than about 60% of its national peers. BuildingCensus bands the score into report-card grades; 60 falls in band C — below median (55–69). It sits 15 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. Infinity Shore Club's 54.8 kBtu/ft² across 107,799 sq ft works out to about 5.9 billion Btu (1,731 MWh-equivalent) in 2025. Its source EUI of 109.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 474,040 kWh of electricity and 13,546 therms of natural gas for the year.
Which law requires Infinity Shore Club to report its energy use?
Infinity Shore Club 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:50933:2025). 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.
