What does an ENERGY STAR score of 63 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 63 means the building performs better than about 63% of its national peers. BuildingCensus bands the score into report-card grades; 63 falls in band C — below median (55–69). It sits 12 points below 75, the threshold for ENERGY STAR certification. 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. 1600 Petersen Ave's 55.6 kBtu/ft² across 39,320 sq ft works out to about 2.2 billion Btu (641 MWh-equivalent) in 2024. Its source EUI of 80.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 147,034 kWh of electricity, 16,856 therms of natural gas and 2,628 thousand gallons of water for the year.

Which law requires 1600 Petersen Ave to report its energy use?

1600 Petersen Ave 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:1284-0-00:2024).
