Stevens Point

The SolarWall®
system is powered by the sun to pre-heat
building ventilation air; thus reducing the heating load and
the building’s fossil fuel consumption. This creates a
more sustainable and healthier building, with improved
fresh air ventilation and lowered heating bills. SolarWall®
solutions enable clients to save money while saving the
environment.
The SolarWall®
system on the Stevens Point Airport hangar
is projected to produce over 73MWh of energy, and
reduce over 19 tons of CO2 annually, yielding a payback
period of just over 6 years. The Stevens Point SolarWall®

system also qualified for a Focus on Energy Incentive, a
Wisconsin based organization that assists cost-effective
energy efficiency and renewable energy projects.

Background

The Stevens Point Municipal Airport is home to a new SolarWall® solar air heating system on a community airport hangar in Wisconsin. The new hangar is designed to accommodate eight single-engine planes, with space in the hangar available for rent by pilots. Like any hangar building, ensuring adequate indoor ventilation is a key consideration. As well, Joe Wheeler, the airport manager at Stevens Point, wanted to guarantee that the ongoing energy costs were lower than a traditional hangar. This lead to the consideration of several sustainability options, and the SolarWall® air heating technology was an easy fit.

Solution

Conserval Systems worked with our Wisconsin representative (Sunny Solutions LLC) to design a SolarWall® system for the solar-rich, south facing wall of the hangar. The SolarWall® system spans 1300ft2 (120m2 ) of collector area. The addition of this black solar system on the white wall creates a visual contrast, and succeeds in drawing attention to the fact that it is a “solar heating wall”.
