Advanced Rooftop Unit Controls (ARC) in a nutshell
Unlock better HVAC performance and greater energy savings for your customers with ARC, a retrofit solution that modernizes an existing rooftop unit (RTU). Traditional RTUs with constant speed fans waste energy, especially when demand is low. By automatically adjusting fan speed and monitoring building needs in real time, ARC provides measurable savings and enhanced comfort for your customers.
The components of ARC
- Unit control – acts as the digital brain of the unit.
- Supply fan VFD or multi-speed fan motor – adjusts the speed of the fan as needed, rather than running at a constant speed (100%).
- CO2 or occupancy-based sensor – detects building occupancy with CO2 sensors and automatically adjusts ventilation rates, minimizing unnecessary fan operation.
- Digitally controlled economizer – brings in the fresh air from outside to help cool your space naturally and reduce the load on the cooling system.
Deliver more value to your customers with ARC
- Help your customers reduce energy use by 30-50%.
- Ensure quick project payback in just one to four years.
- Utilize installation incentives for your ARC projects.
- Deliver lower utility bills for your customers.
- Increase the lifespan of your customer’s RTU.
- Improve occupant comfort.
- Boost indoor air quality.
Market growth
Did you know?
- Roughly 60% of commercial floor spaces use RTUs.
- RTUs make up 20% of all commercial building energy use.
- 73% of these units rely on basic or manual controls.
- That’s 1.9 million buildings in the U.S. ready for major energy savings with better controls.
