What does an ENERGY STAR score of 42 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 42 means the building performs better than about 42% of its national peers. BuildingCensus bands the score into report-card grades; 42 falls in band D — lowest band (1–54). It sits 33 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. Plaza (988 Howard)'s 67.3 kBtu/ft² across 63,501 sq ft works out to about 4.3 billion Btu (1,252 MWh-equivalent) in 2025. Its source EUI of 119.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 520,385 kWh of electricity and 25,005 therms of natural gas for the year.
