Save With Advanced Rooftop Unit Control

Advanced Rooftop Unit Control (ARC) Program
(253) 502-8619 

An Advanced Rooftop Unit Control (ARC) is an energy-saving retrofit solution for constant volume, single-zone packaged rooftop unit (RTU) equipment. These controls work with various RTU manufacturers, have the ability to control and monitor RTUs via the Internet and can reduce utility expenses by more than 50%.

To help, we'll pay up to 70% toward ARCs. Tacoma Power now offers a $225 per ton rebate for electric and a $50 per ton rebate for gas, up to 70% of the qualifying project cost. 

ARCs vs. Standard RTUs

With a standard RTU, the supply fan operates continuously during building occupancy. Fan speed cannot be controlled and supplies constant air volume whether the outdoor air damper is opened or closed.

An ARC offers the following advanced features: 

  • Variable Fan Speeds
    Customizes fan speeds for different modes of operation, such as ventilation, first or second stage heating or cooling.
  • Integrated Air-Side Economizers
    Controls the flow of air with differential dry-bulb temperature control.
  • Demand-Controlled Ventilation
    Uses a return-air CO2 sensor to regulate outdoor-air damper and fan speed controls, to ensure CO2 levels do not exceeded allowable limits.
