How does Volta compare with other office buildings in Portland?
The latest disclosures cover 335 office buildings in Portland, out of 952 buildings citywide. Volta's ENERGY STAR score of 92 compares with an average of 76 across the 256 that report a score; it scores higher than 72% of them and lower than 26%. Its site EUI of 19.2 kBtu/ft² is about 60% below the average of 47.6 kBtu/ft² — it uses less energy per square foot than the typical building in that group.
At 30,162 sq ft, it is about 70% below the average floor area of 100,908 sq ft for those buildings. It was built in 1940, 17 years earlier than the group's average year built (1957). 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 Volta's energy performance changed over time?
BuildingCensus holds 2 Portland disclosures for Volta, covering report years 2023–2024. Only one of those years carries energy figures.
What does an ENERGY STAR score of 92 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 92 means the building performs better than about 92% of its national peers. BuildingCensus bands the score into report-card grades; 92 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 Portland, 66% 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. Volta's 19.2 kBtu/ft² across 30,162 sq ft works out to about 0.6 billion Btu (170 MWh-equivalent) in 2024. The disclosure also reports 170,044 kWh of electricity for the year.
Which law requires Volta to report its energy use?
Volta reports under the Commercial Building Energy Performance Reporting Policy, the legal basis of Portland's Commercial Building Energy Reporting program, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2024 disclosure (source record portland_or:1S1E03DA-3800-B1:2024). Portland requires commercial buildings over 20,000 sq ft to report energy performance annually, with civil penalties for buildings that fail to comply.
