4620 Fortran Dr

How does 4620 Fortran Dr compare with other office buildings in San José?

The latest disclosures cover 408 office buildings in San José, out of 1,790 buildings citywide. 4620 Fortran Dr's ENERGY STAR score of 94 compares with an average of 67 across the 283 that report a score; it scores higher than 82% of them and lower than 16%. Its site EUI of 15.1 kBtu/ft² is about 77% below the average of 64.9 kBtu/ft² — it uses less energy per square foot than the typical building in that group.

At 39,760 sq ft, it is about 58% below the average floor area of 95,555 sq ft for those buildings. It was built in 1970, 16 years earlier than the group's average year built (1986). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².

How has 4620 Fortran Dr's energy performance changed over time?

BuildingCensus holds 6 San José disclosures for 4620 Fortran Dr, covering report years 2019–2024. Its ENERGY STAR score went from 88 in 2020 to 94 in 2024 (+6 points). Site EUI moved from 38.1 kBtu/ft² (2020) to 15.1 kBtu/ft² (2024), a 60% decrease.

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. 4620 Fortran Dr's 15.1 kBtu/ft² across 39,760 sq ft works out to about 0.6 billion Btu (176 MWh-equivalent) in 2024. Its source EUI of 34.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 125,126 kWh of electricity, 1,732 therms of natural gas and 625 thousand gallons of water for the year.

Which law requires 4620 Fortran Dr to report its energy use?

4620 Fortran Dr 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:0006-0-00:2024). San José's BPO requires buildings over 20,000 sq ft to benchmark annually and complete beyond-benchmarking performance improvements on a rolling schedule.
