Advanced Rooftop Unit Control

An Advanced Rooftop Unit Control (ARC) is an energy-saving upgrade that works with constant volume, single-zone packaged rooftop unit (RTU) equipment. These controls, which are monitored via the Internet, work with various RTU manufacturers and can reduce utility expenses by more than 50%.

Tacoma Power will pay up to 100% of the project cost of an ARC for your business. Please see the ARC program application for rebate amounts.

ARCs vs. Standard RTUs

With a standard RTU, the supply fan operates continuously when your building is occupied. And since fan speed cannot be controlled, it supplies constant air volume whether the outdoor air damper is opened or closed. This makes it less efficient than an ARC.

An ARC offers the following benefits:

  • Variable fan speeds allow you to customize for different modes of operation such as ventilation or first or second stage heating or cooling.
  • Integrated air-side economizers control the flow of air with differential dry-bulb temperature control.
  • Demand-controlled ventilation uses a return-air carbon dioxide sensor to regulate outdoor air damper and fan speed controls, which ensures carbon dioxide levels do not exceed allowable limits.

Rebate Process*

  • Contact our experts at (253) 502-8619 or to discuss your project and options.
  • Download, complete, and submit the ARC Rebate Application to us for pre-approval. We will contact you if a pre-installation site verification is required, and when pre-approval is complete.
  • Buy and install the qualifying equipment. New ARC equipment must be purchased and installed in an existing RTU at a business location within our service territory. Please read the ARC Rebate Application for complete details.
  • After installation, complete Attachment A (ARC Functional Testing Sheets) located in the ARC Rebate Application and submit it to us. We will notify you if post-installation site verification is required.
  • We will mail a rebate check after all final project documentation has been reviewed and approved.
