Epiphany School

How does Epiphany School compare with other K-12 school buildings in Seattle?

The latest disclosures cover 153 K-12 school buildings in Seattle, out of 3,871 buildings citywide. Epiphany School's ENERGY STAR score of 85 compares with an average of 71 across the 152 that report a score; it scores higher than 68% of them and lower than 30%. Its site EUI of 37.2 kBtu/ft² is roughly in line with the average of 38.3 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 1.1 kgCO₂e/ft² is roughly in line with the group average of 1.1 kgCO₂e/ft².

At 28,500 sq ft, it is about 64% below the average floor area of 79,329 sq ft for those buildings. It was built in 2009, 39 years later than the group's average year built (1970). Across all 24 jurisdictions BuildingCensus covers, the 6,548 K-12 school buildings average an ENERGY STAR score of 64 and a site EUI of 52.7 kBtu/ft².

How has Epiphany School's energy performance changed over time?

BuildingCensus holds 11 Seattle disclosures for Epiphany School, covering report years 2015–2025. Its ENERGY STAR score went from 90 in 2015 to 85 in 2025 (-5 points); its best year on file was 2016, at 92. Site EUI moved from 39.9 kBtu/ft² (2015) to 37.2 kBtu/ft² (2025), a 7% decrease. Reported emissions went from 27 tCO₂e to 32 tCO₂e over the same span (up 20%).

What does an ENERGY STAR score of 85 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 85 means the building performs better than about 85% of its national peers. BuildingCensus bands the score into report-card grades; 85 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. Epiphany School's 37.2 kBtu/ft² across 28,500 sq ft works out to about 1.1 billion Btu (311 MWh-equivalent) in 2025. Its source EUI of 71.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 170,184 kWh of electricity and 5,768 therms of natural gas for the year.

Which law requires Epiphany School to report its energy use?

Epiphany School 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:25371:2025). 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.
