Confluence Technology Center Moves Below Its EUI Target

Confluence Technology Center, operated by the Chelan-Douglas Regional Port Authority, is a 90,640-square-foot Tier 1 building. SEM activated at the site in June 2025. The client record identifies the building as still in the process of achieving compliance, which is an important distinction even though its reported energy performance had already moved below the listed EUI target.

The initial situation called for both performance improvement and a documented compliance process. Large commercial buildings need reliable utility data, management practices, and operating decisions that can hold up across changing seasons. SEM supported the team by tracking electricity use, comparing current performance with the base year, and giving operations staff information they could use to focus reduction efforts.

The source chart compares June 2024 through May 2025 with the same months in 2025-2026. Base-year electricity use totaled 2,101,133 kWh. Current-year use totaled 1,524,393 kWh. The difference was 576,740 kWh, a 27 percent reduction. No utility-rate information was provided, so this story does not convert that energy result into an estimated dollar value.

The pattern strengthened late in the reporting period. April current-year use was 45 percent below its base comparison, and May was 49 percent lower. Other months varied, including reductions of 7 and 8 percent in February and January. Showing the range avoids implying that every month performed the same while still making the overall improvement clear.

A separate EUI chart shows the building at 57 against a target of 66, nine points below the target. That is a meaningful performance milestone, but the client document still described formal compliance as in process. Energy performance, completed documentation, and Commerce acceptance should not be treated as interchangeable steps.

The source record lists a potential noncompliance penalty of $140,960 if the building does not complete the applicable requirements. The reduction work gives the team a stronger performance position, while the remaining compliance process still requires accurate documentation and completion of the required pathway.

For a prospective owner, Confluence Technology Center shows how regular measurement can turn a broad efficiency goal into a visible operating trend. It also shows why owners should start before the deadline. Better performance helps, but the work is not finished until the building’s records, management programs, and submission meet Commerce requirements.
