What does an ENERGY STAR score of 61 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 61 means the building performs better than about 61% of its national peers. BuildingCensus bands the score into report-card grades; 61 falls in band C — below median (55–69). It sits 14 points below 75, the threshold for ENERGY STAR certification. In New York City, 43% 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. Henn na Hotel's 88.7 kBtu/ft² across 41,584 sq ft works out to about 3.7 billion Btu (1,081 MWh-equivalent) in 2024. Its source EUI of 167.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 516,198 kWh of electricity, 19,266 therms of natural gas and 3,212 thousand gallons of water for the year.
