What does an ENERGY STAR score of 32 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 32 means the building performs better than about 32% of its national peers. BuildingCensus bands the score into report-card grades; 32 falls in band D — lowest band (1–54). It sits 43 points below 75, the threshold for ENERGY STAR certification. In Chicago, 35% 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. Comer Children's Hospital's 242.2 kBtu/ft² across 394,171 sq ft works out to about 95.5 billion Btu (27,979 MWh-equivalent) in 2019. Its source EUI of 424.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 9,604,906 kWh of electricity and 2,579 therms of natural gas for the year.
Which law requires Comer Children's Hospital to report its energy use?
