Capital Upgrade - Implement Full Zone DDC Conversion and Replace Existing End-of-Life Air Handlers Units (AHUs) with High Efficiency Air Handlers Serving Main Building

Not Started

FY 2024




Replace end-of-life, pneumatically controlled, belt-driven AHUs with modern, high efficiency air handling equipment with variable speed drives (VFDs), airside economizers, and DDC control. Replace zone pneumatic variable air volume (VAV) boxes with DDC variable air volume (VAV) boxes for integration into the BAS which will allow improved control, monitoring, and feedback for AHU resets. These air handlers are 20+ years past their end of life, with out of date pneumatic controls, fan belts, broken dampers, linkages & actuators, and are consuming significantly more energy than necessary. This ECM includes the following AHUs:
• Main Building AHU-S1, S2
