What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 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 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. 3940 W BRYN MAWR AVE's 51.8 kBtu/ft² across 76,000 sq ft works out to about 3.9 billion Btu (1,154 MWh-equivalent) in 2022. Its source EUI of 73.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 194,735 kWh of electricity and 24,873 therms of natural gas for the year.
Which law requires 3940 W BRYN MAWR AVE to report its energy use?
