How has Monroe House Condominium's energy performance changed over time?

Its ENERGY STAR score went from 1 in 2013 to 75 in 2024 (+74 points); its best year on file was 2014, at 98. Site EUI moved from 451.7 kBtu/ft² (2013) to 75.7 kBtu/ft² (2024), a 83% decrease. Reported emissions went from 2,878 tCO₂e to 354 tCO₂e over the same span (down 88%).
What does an ENERGY STAR score of 75 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 75 means the building performs better than about 75% of its national peers. BuildingCensus bands the score into report-card grades; 75 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 House Condominium's 75.7 kBtu/ft² across 70,241 sq ft works out to about 5.3 billion Btu (1,558 MWh-equivalent) in 2024. Its source EUI of 131.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 606,598 kWh of electricity, 32,466 therms of natural gas and 1,196 thousand gallons of water for the year.
Which law requires Monroe House Condominium to report its energy use?
