What does an ENERGY STAR score of 28 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 28 means the building performs better than about 28% of its national peers. BuildingCensus bands the score into report-card grades; 28 falls in band D — lowest band (1–54). It sits 47 points below 75, the threshold for ENERGY STAR certification. 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. 2235 Shannon Place's 70.0 kBtu/ft² across 82,184 sq ft works out to about 5.8 billion Btu (1,686 MWh-equivalent) in 2024. Its source EUI of 195.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,685,347 kWh of electricity, 0 therms of natural gas and 30 thousand gallons of water for the year.
