What does an ENERGY STAR score of 69 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 69 means the building performs better than about 69% of its national peers. BuildingCensus bands the score into report-card grades; 69 falls in band C — below median (55–69). It sits 6 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. 2550 N 1St St's 48.1 kBtu/ft² across 74,683 sq ft works out to about 3.6 billion Btu (1,053 MWh-equivalent) in 2024. Its source EUI of 134.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,052,450 kWh of electricity and 1,260 thousand gallons of water for the year.

Which law requires 2550 N 1St St to report its energy use?

2550 N 1St St 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:0591-0-00:2024). San José's BPO requires buildings over 20,000 sq ft to benchmark annually and complete beyond-benchmarking performance improvements on a rolling schedule.
