What does an ENERGY STAR score of 70 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 70 means the building performs better than about 70% of its national peers. BuildingCensus bands the score into report-card grades; 70 falls in band B — above median (70–84). It sits 5 points below 75, the threshold for ENERGY STAR certification. 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. 510 Branham Ln E's 47.9 kBtu/ft² across 44,248 sq ft works out to about 2.1 billion Btu (621 MWh-equivalent) in 2024. Its source EUI of 74.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 179,648 kWh of electricity, 15,055 therms of natural gas and 2,866 thousand gallons of water for the year.

Which law requires 510 Branham Ln E to report its energy use?
