How has Monroe Tower's energy performance changed over time?
BuildingCensus holds 3 Washington, DC disclosures for Monroe Tower, covering report years 2022–2024. Its ENERGY STAR score went from 88 in 2022 to 82 in 2024 (-6 points); its best year on file was 2022, at 88. Site EUI moved from 44.2 kBtu/ft² (2022) to 49.5 kBtu/ft² (2024), an 12% increase. Reported emissions went from 117 tCO₂e to 127 tCO₂e over the same span (up 9%).
What does an ENERGY STAR score of 82 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 82 means the building performs better than about 82% of its national peers. BuildingCensus bands the score into report-card grades; 82 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. Monroe Tower's 49.5 kBtu/ft² across 35,755 sq ft works out to about 1.8 billion Btu (519 MWh-equivalent) in 2024. Its source EUI of 99.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 281,423 kWh of electricity, 8,099 therms of natural gas and 3,139 thousand gallons of water for the year.
Which law requires Monroe Tower to report its energy use?
Monroe Tower 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:PM24741407:2024). 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.
