What does an ENERGY STAR score of 98 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 98 means the building performs better than about 98% of its national peers. BuildingCensus bands the score into report-card grades; 98 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 California, 65% 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. The Wilson-Greystar's 37.0 kBtu/ft² across 58,091 sq ft works out to about 2.1 billion Btu (630 MWh-equivalent) in 2020. The disclosure also reports 279,692 kWh of electricity and 11,722 therms of natural gas for the year.
Which law requires The Wilson-Greystar to report its energy use?
