Its site EUI of 85.6 kBtu/ft² is about 54% above the average of 55.6 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 11.5 kgCO₂e/ft² is about 130% above the group average of 5.0 kgCO₂e/ft².
At 110,129 sq ft, it is about half of the average floor area of 216,135 sq ft for those buildings. It was built in 1971, 3 years earlier than the group's average year built (1974).

What does an ENERGY STAR score of 39 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 39 means the building performs better than about 39% of its national peers. BuildingCensus bands the score into report-card grades; 39 falls in band D — lowest band (1–54). It sits 36 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. Meitnerium, LLC's 85.6 kBtu/ft² across 110,129 sq ft works out to about 9.4 billion Btu (2,763 MWh-equivalent) in 2015. Its source EUI of 268.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,761,984 kWh of electricity, 0 therms of natural gas and 3,775 thousand gallons of water for the year.
Which law requires Meitnerium, LLC to report its energy use?
