What does an ENERGY STAR score of 62 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 62 means the building performs better than about 62% of its national peers. BuildingCensus bands the score into report-card grades; 62 falls in band C — below median (55–69). It sits 13 points below 75, the threshold for ENERGY STAR certification. In Ann Arbor, 57% 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. 809 East Kingsley's 79.2 kBtu/ft² across 31,177 sq ft works out to about 2.5 billion Btu (724 MWh-equivalent) in 2023. Its source EUI of 99.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,924 thousand gallons of water for the year.

Which law requires 809 East Kingsley to report its energy use?

809 East Kingsley reports under the Benchmarking and Disclosure Ordinance (2021), the legal basis of Ann Arbor's Energy & Water Benchmarking program, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2023 disclosure (source record ann_arbor:A2BLD-00561:2023). Ann Arbor's ordinance requires commercial buildings over 20,000 sq ft to benchmark and disclose annually as part of the A2ZERO carbon-neutrality plan.
