What does an ENERGY STAR score of 88 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 88 means the building performs better than about 88% of its national peers. BuildingCensus bands the score into report-card grades; 88 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. Klee Plaza at Six Corners Condominium's 49.2 kBtu/ft² across 94,000 sq ft works out to about 4.6 billion Btu (1,355 MWh-equivalent) in 2023. Its source EUI of 80.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 446,738 kWh of electricity and 30,990 therms of natural gas for the year.
