This is 9,800 square feet of solar wall which is equivalent to 420kW capacity heating system. MB Roofing was the installer and SolSource supplied the materials and design management for the project.
Solar Wall at the Aurora Supercenter:
The south-facing wall of the store is covered with a perforated metal siding. Heat build-up from the sun warms the air in the wall cavity by 10 to 20 degrees depending upon the season and weather conditions. This warm air rises to the top of the wall by heat convection. The store's ventilation system then draws that warmed air into the Supercenter.
This "natural" pre-heating system means less energy is needed to run the mechanical heating systems and less natural gas is needed to heat the store. In the summer when no heating is required, the warm air generated by the south-facing solar wall does not enter the store, but is released at the top of the wall. The wall acts as a solar shield, reducing solar heat gain and reducing cooling needs in the stockroom.
