How has Waterfront Station l's energy performance changed over time?
BuildingCensus holds 11 Washington, DC disclosures for Waterfront Station l, covering report years 2012, 2014, 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023. Its ENERGY STAR score went from 78 in 2012 to 83 in 2023 (+5 points); its best year on file was 2014, at 84. Site EUI moved from 89.1 kBtu/ft² (2012) to 70.7 kBtu/ft² (2023), a 21% decrease. Reported emissions went from 3,735 tCO₂e to 2,144 tCO₂e over the same span (down 43%).
What does an ENERGY STAR score of 83 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 83 means the building performs better than about 83% of its national peers. BuildingCensus bands the score into report-card grades; 83 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. Waterfront Station l's 70.7 kBtu/ft² across 355,846 sq ft works out to about 25.2 billion Btu (7,373 MWh-equivalent) in 2023. Its source EUI of 182.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 6,430,573 kWh of electricity, 31,544 therms of natural gas and 362 thousand gallons of water for the year.
Which law requires Waterfront Station l to report its energy use?
Waterfront Station l 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 2023 disclosure (source record dc:PM2590110:2023). 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.
