Installation of an Earth Tube at a PA Creamery. This REHAU ground air heat exchanger preconditions incoming ventilation air. Operating 24/7, this renewable energy delivery system is capable of delivering annual energy equivalent to 26 - 200W solar PV at 1/5th the cost. This technology is widely used throughout Europe and should be evaluated as part of any comprehensive renewable energy strategy. Installation will reduce a buildings heating & cooling costs, energy intensity and carbon impact.
