Havtech recommended a hybrid system combining Daikin Emerion VRV units and Rebel rooftop units. The VRV system’s modular layout and small-diameter refrigerant piping allowed for flexible zoning and installation within the building’s existing framework. Daikin Rebel rooftop units delivered high-efficiency air handling in a compact footprint, eliminating the need for extensive structural changes or mechanical rooms. Additionally, native controls simplified BAS integration reducing the need for third-party coordination during commissioning.
