Variable Refrigerant Flow (VRF) zoning and geothermal systems (or water-source) are two of the most energy-efficient options for heating and cooling available in the U.S. today. Fortunately, technology exists that combines the benefits of both systems.
A proven HVAC technology wordwide, Variable Refrigerant Flow (VRF) zoning systems are poised for dramatic growth in all areas of commercial construction because they provide precise zones control that can contribute toward the achievement of LEED certifications.
The author’s longtime interest in bundling efficiency techniques in a single system eventually led him to a new pairing: VRF zoning technology and geothermal design. See how he got there and how this couple played out for an historic 107-year-old Iowa courthouse that serves the law through the area’s brutal winters and humid summers.
