How has 901 K Street (DDOE)'s energy performance changed over time?
BuildingCensus holds 2 Washington, DC disclosures for 901 K Street (DDOE), covering report years 2014–2015. Its ENERGY STAR score went from 90 in 2014 to 88 in 2015 (-2 points); its best year on file was 2014, at 90. Site EUI moved from 50.2 kBtu/ft² (2014) to 53.0 kBtu/ft² (2015), an 6% increase. Reported emissions went from 1,940 tCO₂e to 2,043 tCO₂e over the same span (up 5%).
What does an ENERGY STAR score of 88 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 88 means the building performs better than about 88% of its national peers. BuildingCensus bands the score into report-card grades; 88 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 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. 901 K Street (DDOE)'s 53.0 kBtu/ft² across 288,144 sq ft works out to about 15.3 billion Btu (4,476 MWh-equivalent) in 2015. Its source EUI of 166.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 4,471,734 kWh of electricity, 0 therms of natural gas and 4,567 thousand gallons of water for the year.
Which law requires 901 K Street (DDOE) to report its energy use?
