SolarWall® air heating systems work especially well in cold and northern
climates because the low azimuth of the spring sun reflects the sunlight off the snow. This enhances the performance of the system by 50-70%, which compensates for the shortened duration. The returns are also substantial given the high proportion of days in the spring, summer, and fall that are extremely sunny, yet very cold. This means that heated indoor air is always required.
Conserval Engineering was contacted to design and supply a renewable thermal heating system in a retrofit application at the high school gym annex at Alaittuq School in Rankin Inlet, Nunavut. A 710 ft2 (66 m2) green SolarWall heater was installed and connected into the existing ventilation system, upstream from the heating coils.
One of the additional goals was that the solar heating system would
serve as an educational tool in instructing students about environmental technologies.
