How has 1200 Nineteenth Street Benchmarking's energy performance changed over time?

BuildingCensus holds 12 Washington, DC disclosures for 1200 Nineteenth Street Benchmarking, covering report years 2012, 2014, 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024. Its ENERGY STAR score went from 89 in 2014 to 78 in 2024 (-11 points); its best year on file was 2015, at 90. Site EUI moved from 58.3 kBtu/ft² (2014) to 44.8 kBtu/ft² (2024), a 23% decrease. Reported emissions went from 2,513 tCO₂e to 1,294 tCO₂e over the same span (down 49%).

What does an ENERGY STAR score of 78 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 78 means the building performs better than about 78% of its national peers. BuildingCensus bands the score into report-card grades; 78 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. 1200 Nineteenth Street Benchmarking's 44.8 kBtu/ft² across 354,926 sq ft works out to about 15.9 billion Btu (4,660 MWh-equivalent) in 2024. Its source EUI of 111.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,800,446 kWh of electricity, 29,356 therms of natural gas and 4,879 thousand gallons of water for the year.

Which law requires 1200 Nineteenth Street Benchmarking to report its energy use?

1200 Nineteenth Street Benchmarking reports under the Clean and Affordable Energy Act / BEPS, the legal basis of Washington, DC's Building Energy Benchmarking program, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2024 disclosure (source record dc:PM3500466:2024). DC's Building Energy Performance Standards (BEPS) require buildings below the performance standard to improve over compliance cycles (the first ends December 31, 2026; later cycles run five years), with penalties for buildings that fail to meet their pathway.
