Its site EUI of 62.9 kBtu/ft² is roughly in line with the average of 62.9 kBtu/ft².
At 74,225 sq ft, it is about 19% below the average floor area of 92,016 sq ft for those buildings. It was built in 1956, 10 years earlier than the group's average year built (1966).

What does an ENERGY STAR score of 67 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 67 means the building performs better than about 67% of its national peers. BuildingCensus bands the score into report-card grades; 67 falls in band C — below median (55–69). It sits 8 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. Ellis Elementary's 62.9 kBtu/ft² across 74,225 sq ft works out to about 4.7 billion Btu (1,368 MWh-equivalent) in 2023. The disclosure also reports 206,402 kWh of electricity and 39,630 therms of natural gas for the year.
Which law requires Ellis Elementary to report its energy use?
