What does an ENERGY STAR score of 38 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 38 means the building performs better than about 38% of its national peers. BuildingCensus bands the score into report-card grades; 38 falls in band D — lowest band (1–54). It sits 37 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. 111 K Street's 70.8 kBtu/ft² across 84,540 sq ft works out to about 6 billion Btu (1,754 MWh-equivalent) in 2017. Its source EUI of 222.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,753,068 kWh of electricity, 0 therms of natural gas and 721 thousand gallons of water for the year.
