Project Description


Automobile Club of Southern California recently set out to upgrade their mechanical systems at the AAA Glendale, California location.  CGK Consulting Group in coordination with Techne Control Systems and California Comfort Systems designed and installed a new multi-zone variable-air-volume (VAV) split system with hydronic hot water reheat.  The nine zone system allows AAA to efficiency control the temperature of their public and private office spaces using the Carrier i-Vu 7.0 building automation system.

Controls Architecture

CGK Consulting Group’s MEP and Controls engineering department collaborated on equipment and controls specifications to developed an integrated Building Automation System (BAS) architecture to provide centralized control building systems.  This architecture utilizes multiple communication mediums including traditional analog and digital signals, BACnet MS/TP, and BACnet IP communications under an i-Vu Pro 7.0 server.  The system consisted of 9 Carrier VAVB1-02 controllers for zone control, 1 UCXP for air handler control, 1 OPEN-UPC for condenser control, and 3rd party BACnet field servers for miscellaneous device integration, such as a Raypak decoupled hydronic heating boiler.

Hardware & Software Engineering

Techne Control Systems, the control implementation subsidiary of CGK Consulting Group, designed, built, and installed a custom control panel centered around the Carrier i-Vu UCXP programmable controller and XT-RB BACnet gateway.  Control programming and human machine interface development was performed off-site at Techne Control Systems development lab and then installed ready for commissioning at the client site.  In parallel with the mechanical installation, Techne performed the installation the installation of instrumentation, final control elements, point-to-point wiring, BACnet wiring, and CAT6 networking throughout the building to ensure a timely start up.  This Design-Build implementation by AAA, CGK Consulting Group, Techne Control Systems, and California Comfort Systems is another successful use of integrated project delivery to meet and exceed the customer expectations of performance an project execution.
