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 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. 3477 Lily Way's 49.3 kBtu/ft² across 153,782 sq ft works out to about 7.6 billion Btu (2,222 MWh-equivalent) in 2024. Its source EUI of 76.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 624,135 kWh of electricity, 54,593 therms of natural gas and 4,680 thousand gallons of water for the year.

Which law requires 3477 Lily Way to report its energy use?

3477 Lily Way reports under San José Municipal Code Ch. 17.85 (Energy and Water Building Performance Ordinance), the legal basis of San José's Energy and Water Building Performance Ordinance, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2024 disclosure (source record san_jose:0057-0-00:2024).
