What does an ENERGY STAR score of 59 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 59 means the building performs better than about 59% of its national peers. BuildingCensus bands the score into report-card grades; 59 falls in band C — below median (55–69). It sits 16 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. Parkside Apartments's 81.4 kBtu/ft² across 37,000 sq ft works out to about 3 billion Btu (883 MWh-equivalent) in 2024. Its source EUI of 115.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 182,776 kWh of electricity, 23,877 therms of natural gas and 1,170 thousand gallons of water for the year.

Which law requires Parkside Apartments to report its energy use?

Parkside Apartments 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:PM19573861:2024). 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.
