What does an ENERGY STAR score of 45 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 45 means the building performs better than about 45% of its national peers. BuildingCensus bands the score into report-card grades; 45 falls in band D — lowest band (1–54). It sits 30 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. The Parkwest's 84.6 kBtu/ft² across 84,500 sq ft works out to about 7.1 billion Btu (2,095 MWh-equivalent) in 2024. Its source EUI of 122.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 469,575 kWh of electricity, 55,439 therms of natural gas and 2,138 thousand gallons of water for the year.
Which law requires The Parkwest to report its energy use?
