Ground source saves medical building 70%

In Washington, while it may take years to recoup initial investment costs, while it does, a medical building in Spokane is using a ground-source heat pump to heat and cool their building, and saving 70% in energy bills. Owner David Owan said that the heat exchange unit alone cost around $690,000, which is more than twice what it would have cost for a conventional heating and cooling system for what is a 23,000-square-foot building. However, while a traditional HVAC system would cost about $4,000 per month in energy bills, his heating and cooling system is only about $1,200 per month, 70% less.
