Cold Climate Variable Refrigerant Flow Program Study

Published in

Variable refrigerant flow (VRF) systems are viable for use in cold climates such as Wisconsin. Few projects in Wisconsin have adopted the technology, so limited field data exist to confirm the energy, economic and comfort performance of these systems in Wisconsin.

Along with the Center for Energy and Environment, Slipstream completed a study on VRF systems in Wisconsin to understand the market barriers, the typical energy and cost savings and to develop a program framework for Focus on Energy to implement. To accomplish these tasks, we interviewed stakeholders (VRF manufacturers, contractors, energy efficiency program staff), developed energy and economic models, and assessed five sites in the state with VRF systems.
