The Three Rivers Park District's desire for the Silverwood Park Visitor Center was to showcase and promote sustainability and reduce their day-to-day operating costs. With that in mind, LKPB set its own project goal - reduce the building's overall impact on the environment while presenting a sustainable building to the community.
After a cost analysis comparing various types of heating and cooling systems, a geothermal heat pump system was selected. The analysis included soil bore testing from the construction site. Along with having low operating costs, a geothermal heat pump system would promote the park district's desire to incorporate sustainable practices into the design of the building.
The geothermal heat pump system (see photo) is a closed-loop type consisting of 52 vertical wells extending to a depth of nearly 200 feet below the parking lot that sits on top of it. The maintenance garage at the park has a separate geothermal system containing four wells. The design of the Visitor Center follows the State of Minnesota Sustainable Building Guidelines.
