How has 1729 N 1St St's energy performance changed over time?

BuildingCensus holds 7 San José disclosures for 1729 N 1St St, covering report years 2018–2024. Its ENERGY STAR score went from 85 in 2018 to 94 in 2024 (+9 points).

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. 1729 N 1St St's 30.8 kBtu/ft² across 426,639 sq ft works out to about 13.1 billion Btu (3,851 MWh-equivalent) in 2024. Its source EUI of 67.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,541,508 kWh of electricity, 44,498 therms of natural gas and 14,017 thousand gallons of water for the year.

Which law requires 1729 N 1St St to report its energy use?

1729 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:0325-0-00:2024).
