Its ENERGY STAR score went from 100 in 2017 to 99 in 2025 (-1 points); its best year on file was 2017, at 100. Site EUI moved from 25.7 kBtu/ft² (2017) to 36.5 kBtu/ft² (2025), an 42% increase. Reported emissions went from 73 tCO₂e to 79 tCO₂e over the same span (up 9%).
What does an ENERGY STAR score of 99 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 99 means the building performs better than about 99% of its national peers. BuildingCensus bands the score into report-card grades; 99 falls in band A — high performer (85–100). 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 Seattle, 69% 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. Anthem On 12th's 36.5 kBtu/ft² across 116,576 sq ft works out to about 4.3 billion Btu (1,247 MWh-equivalent) in 2025. Its source EUI of 76.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 576,004 kWh of electricity and 12,999 therms of natural gas for the year.
Which law requires Anthem On 12th to report its energy use?
