The Canadian government has committed to decreasing the country’s carbon footprint by reducing dependency on fossil fuels and lowering emissions. The HVAC industry can play an important role in this effort: In Canada, buildings produce 17% of greenhouse gases, in large part due to the fossil fuels used for heating and cooling[1]. Energy-efficient Variable Refrigerant Flow (VRF) systems can be installed in both new and retrofit projects, helping to address this problem.

Ductless VRF systems provide significant energy savings by virtually eliminating the energy loss associated with ductwork that occurs in traditional HVAC systems. In fact, Hitachi VRF Sigma Systems are estimated to save up to 39% over conventional systems. Further, VRF systems provide zoned heating and cooling, enabling energy savings in unoccupied areas. And they can be sized to meet current needs exactly while easily accommodating future expansion. VRF systems are a proven technology widely used throughout Europe and Asia. As the country works to meet its climate goals, VRF systems, such as Hitachi VRF Sigma, are a ready solution that can help make Canadian buildings more energy-efficient.
