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 Los Angeles, 63% 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. 1840 WINONA BLVD's 35.5 kBtu/ft² across 35,895 sq ft works out to about 1.3 billion Btu (373 MWh-equivalent) in 2025. Its source EUI of 69.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,080 thousand gallons of water for the year.
