Benefits of VRF in the LEED® Certification Process

This article ran 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, operation and maintenance management 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.
