What does an ENERGY STAR score of 14 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 14 means the building performs better than about 14% of its national peers. BuildingCensus bands the score into report-card grades; 14 falls in band D — lowest band (1–54). It sits 61 points below 75, the threshold for ENERGY STAR certification. In San Francisco, 73% 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. 2500 ARELIOUS WALKER DR's 82.0 kBtu/ft² across 80,360 sq ft works out to about 6.6 billion Btu (1,931 MWh-equivalent) in 2025. Its source EUI of 174.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,186,573 kWh of electricity and 25,410 therms of natural gas for the year.
Which law requires 2500 ARELIOUS WALKER DR to report its energy use?
