Grant Bowers, PE, LEED APGrant Bowers, PE, LEED AP, is featured in a two-part article series in HPAC Engineering Magazine, focused on pairing a Dedicated Outdoor-Air-Systems (DOAS) with a Variable-Refrigerant-Flow (VRF) system to achieve simplified system design and increased efficiencies for institutional buildings.

Part I of Bowers’ article explores the combination of DOAS and VRF systems, limitations and drawbacks of Variable-Air-Volume (VAV) system installation and operation, and recommendations for improving VAV system operation and reducing risk and uncertainty in the delivery of ventilation. Part II of Bowers article discusses the merits and challenges of combining dedicated outdoor-air systems (DOAS) and variable-refrigerant-flow (VRF) systems.
