Compliance context
Energize Denver Building Performance Policy
Energize Denver sets energy-use (EUI) targets for buildings of 25,000+ sq ft — for most buildings an interim target in 2028 and a final target in 2032 — with civil penalties of roughly $0.15–0.35 per kBtu over target for non-compliance.

How does Skinner compare with other K-12 school buildings in Denver?
The latest disclosures cover 192 K-12 school buildings in Denver, out of 3,287 buildings citywide. Skinner's ENERGY STAR score of 37 compares with an average of 58 across the 189 that report a score; it scores higher than 19% of them and lower than 78%. Its site EUI of 88.1 kBtu/ft² is about 40% above the average of 62.9 kBtu/ft² — it uses more energy per square foot than the typical building in that group.
At 148,821 sq ft, it is about 62% above the average floor area of 92,016 sq ft for those buildings. It was built in 1922, 44 years earlier than the group's average year built (1966). 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.
What does an ENERGY STAR score of 37 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 37 means the building performs better than about 37% of its national peers. BuildingCensus bands the score into report-card grades; 37 falls in band D — lowest band (1–54). It sits 38 points below 75, the threshold for ENERGY STAR certification. In Denver, 54% 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. Skinner's 88.1 kBtu/ft² across 148,821 sq ft works out to about 13.1 billion Btu (3,842 MWh-equivalent) in 2023. The disclosure also reports 998,450 kWh of electricity and 97,110 therms of natural gas for the year.
Which law requires Skinner to report its energy use?
Skinner reports under the Energize Denver Building Performance Policy, the legal basis of Denver's Energize Denver Benchmarking program, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2023 disclosure (source record denver:1979:2023). Energize Denver sets energy-use (EUI) targets for buildings of 25,000+ sq ft — for most buildings an interim target in 2028 and a final target in 2032 — with civil penalties of roughly $0.15–0.35 per kBtu over target for non-compliance.
