What does an ENERGY STAR score of 84 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 84 means the building performs better than about 84% of its national peers. BuildingCensus bands the score into report-card grades; 84 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 Washington, DC, 47% 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. 1121 Fourteenth Street NW (Neuroscience)'s 29.7 kBtu/ft² across 87,159 sq ft works out to about 2.6 billion Btu (759 MWh-equivalent) in 2024. Its source EUI of 83.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 758,430 kWh of electricity, 0 therms of natural gas and 694 thousand gallons of water for the year.
