Its site EUI of 22.0 kBtu/ft² is about 41% above the average of 15.6 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 0.1 kgCO₂e/ft² is about half of the group average of 0.3 kgCO₂e/ft².
At 111,845 sq ft, it is about 27% above the average floor area of 88,206 sq ft for those buildings. It was built in 2016, 40 years later than the group's average year built (1976). Across all 24 jurisdictions BuildingCensus covers, the 3,050 self-storage facility buildings average an ENERGY STAR score of 75 and a site EUI of 9.4 kBtu/ft².
How has Rainier Storage LLC (Phase I)'s energy performance changed over time?
BuildingCensus holds 6 Seattle disclosures for Rainier Storage LLC (Phase I), covering report years 2019–2024. Site EUI moved from 23.7 kBtu/ft² (2019) to 22.0 kBtu/ft² (2024), a 7% decrease. Reported emissions went from 18 tCO₂e to 17 tCO₂e over the same span (down 6%).
What does a site EUI of 22.0 kBtu/ft² mean?
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. Rainier Storage LLC (Phase I)'s 22.0 kBtu/ft² across 111,845 sq ft works out to about 2.5 billion Btu (721 MWh-equivalent) in 2024. Its source EUI of 60.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 706,581 kWh of electricity and 480 therms of natural gas for the year.
Which law requires Rainier Storage LLC (Phase I) to report its energy use?
Rainier Storage LLC (Phase I) 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:50429:2024). 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.
