The Camp Cole project is a unique, fully accessible camp and retreat facility for all people, but with a particular heart to help people who might be dealing with serious illness or a disability. Camp Cole has a medical facility and conference center. The HVAC is driven by a VRF (variable refrigerant flow) system which is a two-pipe heat recovery system that simultaneously heats and cools different zones within the building. The system provides an energy efficient approach and a small footprint along with quiet operating levels.
