Its site EUI of 25.0 kBtu/ft² is about 29% below the average of 35.3 kBtu/ft² — it uses less energy per square foot than the typical building in that group.

At 78,932 sq ft, it is about half of the average floor area of 157,540 sq ft for those buildings. It was built in 1999, 12 years later than the group's average year built (1987). Across all 24 jurisdictions BuildingCensus covers, the 59,945 multifamily housing buildings average an ENERGY STAR score of 70 and a site EUI of 59.0 kBtu/ft².

How has 1640 Hermocilla Way's energy performance changed over time?

BuildingCensus holds 7 San José disclosures for 1640 Hermocilla Way, covering report years 2018–2024.

What does an ENERGY STAR score of 98 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 98 means the building performs better than about 98% of its national peers. BuildingCensus bands the score into report-card grades; 98 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. 1640 Hermocilla Way's 25.0 kBtu/ft² across 78,932 sq ft works out to about 2 billion Btu (578 MWh-equivalent) in 2024. Its source EUI of 50.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 324,939 kWh of electricity, 8,676 therms of natural gas and 4,150 thousand gallons of water for the year.

Which law requires 1640 Hermocilla Way to report its energy use?

1640 Hermocilla 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:1768-0-00:2024). San José's BPO requires buildings over 20,000 sq ft to benchmark annually and complete beyond-benchmarking performance improvements on a rolling schedule.
