How has 2010 N 1St St's energy performance changed over time?

BuildingCensus holds 7 San José disclosures for 2010 N 1St St, covering report years 2018–2024. Its ENERGY STAR score went from 51 in 2018 to 93 in 2024 (+42 points).

What does an ENERGY STAR score of 93 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 93 means the building performs better than about 93% of its national peers. BuildingCensus bands the score into report-card grades; 93 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. 2010 N 1St St's 30.2 kBtu/ft² across 85,357 sq ft works out to about 2.6 billion Btu (755 MWh-equivalent) in 2024. Its source EUI of 84.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 754,478 kWh of electricity, 0 therms of natural gas and 1,867 thousand gallons of water for the year.

Which law requires 2010 N 1St St to report its energy use?

2010 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:0528-0-00:2024). San José's BPO requires buildings over 20,000 sq ft to benchmark annually and complete beyond-benchmarking performance improvements on a rolling schedule.
