Reported emissions went from 461 tCO₂e to 453 tCO₂e over the same span (down 2%).

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 Kansas City, 46% 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. 21TEN Condominiums's 42.7 kBtu/ft² across 85,000 sq ft works out to about 3.6 billion Btu (1,064 MWh-equivalent) in 2023. Its source EUI of 119.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 927 thousand gallons of water for the year.

Which law requires 21TEN Condominiums to report its energy use?

21TEN Condominiums reports under the Energy Empowerment Ordinance (No. 150299), the legal basis of Kansas City's Energy and Water Benchmarking program, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2023 disclosure (source record kansas_city:05-MF-01025:2023). Kansas City's Energy Empowerment Ordinance requires annual energy and water benchmarking for commercial and multifamily buildings over 50,000 sq ft (and for city-owned buildings), with public disclosure of results.
