Additional Information

Designed to be a "net zero energy" building.

Camden State Park Office/Information Building
Minnesota Department of Natural Resources
Marshall, Minnesota

In 2008 the Minnesota DNR selected LKPB to provide mechanical/electrical design consulting services for a major addition/remodel project for Camden State Park's office/information building. In order to help the DNR attain its goal of "net zero energy" use for this facility, LKPB utilized both wind turbine power generation and a geothermal heat pump system.

The 120-foot wind turbine is a 10 kW Bergey XLS. It is expected to produce about 12,000 kW of electricity annually. When the turbine generates more power than the park can use, excess power goes back to the local utility company in the form of power "credits" that can be used later. The geothermal heat pump system is a 4-ton, vertical, closed-loop ground source heat pump that extracts ground heat in the winter (for heating) and transfers heat back into the ground in the summer (for cooling). The system utilizes four, 200-foot deep wells.

This project is a tremendous opportunity for the public to learn about sustainable systems and the DNR's commitment to reducing their energy consumption and carbon footprint.
