What does an ENERGY STAR score of 96 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 96 means the building performs better than about 96% of its national peers. BuildingCensus bands the score into report-card grades; 96 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. Two West Delaware (dt38)'s 17.0 kBtu/ft² across 703,611 sq ft works out to about 12 billion Btu (3,506 MWh-equivalent) in 2023. Its source EUI of 47.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,506,535 kWh of electricity for the year.
