Project details

Authorized Dealer Control Concepts Ohio installed a Reliable Controls building automation during a retrofit of Zulily’s Lockbourne warehouse in 2023.

The backbone of the building automation system is RC-Studio, an easy to learn and use BACnet Advanced Operator Workstation (B-AWS) software program that helped Control Concepts Ohio improve energy use and operational efficiency in the facility while integrating Reliable Controls controllers and equipment from other brands. Before the installation, building managers had issues with communications and operating performance. The Reliable Controls system provides a stable network that promotes occupant comfort and controls 50 rooftop units according to zone sequencing.

The biggest challenge of the retrofit was discovering equipment in need of repair, which sometimes required several hours of troubleshooting after installation of the Reliable Controls system.

Forty-six fully programmable MACH-ProZone controllers, ideal for controlling midsize rooftop and heat-pump applications and small mechanical room equipment, provide highly scalable inputs and outputs in a compact package. In addition, each zone now has a SMART-Sensor device that delivers occupancy status, which provides an excellent means to improve energy and operational efficiency.

Installing variable frequency drives on the rooftop units meant the fans could soft start and operate at a lower speed during periods of low demand. Control Concepts Ohio integrated power meters and ceiling fans into the building automation system for demand-limited control and to decrease peaks in energy use, saving thousands of dollars every month.
