What does an ENERGY STAR score of 94 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 94 means the building performs better than about 94% of its national peers. BuildingCensus bands the score into report-card grades; 94 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 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. 1180 Fourth Street's 37.1 kBtu/ft² across 251,076 sq ft works out to about 9.3 billion Btu (2,730 MWh-equivalent) in 2025. Its source EUI of 57.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 781,194 kWh of electricity and 66,411 therms of natural gas for the year.

Which law requires 1180 Fourth Street to report its energy use?
