How does Isabella Bird 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. Isabella Bird's ENERGY STAR score of 64 compares with an average of 58 across the 189 that report a score; it scores higher than 54% of them and lower than 42%. Its site EUI of 59.0 kBtu/ft² is roughly in line with the average of 62.9 kBtu/ft² — it uses less energy per square foot than the typical building in that group.
At 93,512 sq ft, it is roughly in line with the average floor area of 92,016 sq ft for those buildings. It was built in 2013, 47 years later 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 64 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 64 means the building performs better than about 64% of its national peers. BuildingCensus bands the score into report-card grades; 64 falls in band C — below median (55–69). It sits 11 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. Isabella Bird's 59.0 kBtu/ft² across 93,512 sq ft works out to about 5.5 billion Btu (1,617 MWh-equivalent) in 2023. The disclosure also reports 542,313 kWh of electricity and 36,656 therms of natural gas for the year.
