Format On Demand: Article/Print
Offered by Hanley Wood, LLC
Category Energy and atmosphere

This article is available in the October 2011 print and digital editions of ARCHTIECT Magazine. This program compares traditional HVAC systems to variable refrigerant flow (VRF) systems. General features and benefits of VRF systems are discussed, including energy efficiency, installation, operation and potential contribution to LEED rating systems. Architects, building owners, contractors and facilty managers will be introduced to VRF systems. Three case examples are presented, describing why VRF was selected for each of the projects and what the estimated benefits of the VRF system were in each case. Finally, a brief overview of VRF systems in building information modeling (BIM) is presented.


  1. Describe the basic differences between VRF and split-ductless HVAC systems.
  2. Recall the LEED categories where VRF and split-ductless systems provide credit opportunities.
  3. Describe a minimum of three design challenges that were met with a VRF solution, using examples from this article.
  4. List three advantages VRF provides for BIM.
