The latest disclosures cover 257 hotel buildings in Washington, DC, out of 6,870 buildings citywide. Suton One LLC's ENERGY STAR score of 14 compares with an average of 58 across the 251 that report a score; it scores higher than 8% of them and lower than 92%. Its site EUI of 97.9 kBtu/ft² is about 12% above the average of 87.6 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 8.5 kgCO₂e/ft² is about 23% above the group average of 6.9 kgCO₂e/ft².

At 69,000 sq ft, it is about 70% below the average floor area of 227,860 sq ft for those buildings. It was built in 2008, 34 years later than the group's average year built (1974). Across all 24 jurisdictions BuildingCensus covers, the 3,812 hotel buildings average an ENERGY STAR score of 65 and a site EUI of 77.8 kBtu/ft².

What does an ENERGY STAR score of 14 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 14 means the building performs better than about 14% of its national peers. BuildingCensus bands the score into report-card grades; 14 falls in band D — lowest band (1–54). It sits 61 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. Suton One LLC's 97.9 kBtu/ft² across 69,000 sq ft works out to about 6.8 billion Btu (1,980 MWh-equivalent) in 2017. Its source EUI of 223.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,170,591 kWh of electricity, 27,607 therms of natural gas and 5,023 thousand gallons of water for the year.

Which law requires Suton One LLC to report its energy use?

Suton One LLC 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 2017 disclosure (source record dc:PM6272843:2017). 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.
