What does an ENERGY STAR score of 80 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 80 means the building performs better than about 80% of its national peers. BuildingCensus bands the score into report-card grades; 80 falls in band B — above median (70–84). 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. Parkways, The (IL)'s 51.4 kBtu/ft² across 467,893 sq ft works out to about 24 billion Btu (7,048 MWh-equivalent) in 2017. Its source EUI of 97.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,858,632 kWh of electricity and 142,989 therms of natural gas for the year.

Which law requires Parkways, The (IL) to report its energy use?
