How does 1920 L St: 1920 L Street Northwest compare with other office buildings in Washington, DC?
The latest disclosures cover 899 office buildings in Washington, DC, out of 6,870 buildings citywide. 1920 L St: 1920 L Street Northwest's ENERGY STAR score of 77 compares with an average of 70 across the 774 that report a score; it scores higher than 53% of them and lower than 44%. Its site EUI of 68.2 kBtu/ft² is about 23% 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 6.6 kgCO₂e/ft² is about 32% above the group average of 5.0 kgCO₂e/ft².
At 117,719 sq ft, it is about half of the average floor area of 216,135 sq ft for those buildings. It was built in 1968, 6 years earlier than the group's average year built (1974). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².
What does an ENERGY STAR score of 77 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 77 means the building performs better than about 77% of its national peers. BuildingCensus bands the score into report-card grades; 77 falls in band B — above median (70–84). 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. 1920 L St: 1920 L Street Northwest's 68.2 kBtu/ft² across 117,719 sq ft works out to about 8 billion Btu (2,353 MWh-equivalent) in 2016. Its source EUI of 173.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,681,050 kWh of electricity, 22,944 therms of natural gas and 1,335 thousand gallons of water for the year.
Which law requires 1920 L St: 1920 L Street Northwest to report its energy use?
