What does an ENERGY STAR score of 88 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 88 means the building performs better than about 88% of its national peers. BuildingCensus bands the score into report-card grades; 88 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 San José, 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. 4020 Moorpark Ave's 28.2 kBtu/ft² across 21,364 sq ft works out to about 0.6 billion Btu (177 MWh-equivalent) in 2024. Its source EUI of 70.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 146,972 kWh of electricity, 1,002 therms of natural gas and 348 thousand gallons of water for the year.

Which law requires 4020 Moorpark Ave to report its energy use?
