Solar cladding is a metal cladding consisting of thousands of tiny perforations and is mounted approximately 6-12 inches out from the exterior south-facing wall. As the sun shines, a ventilation fan draws warm air from the boundary layer on the surface of the wall through the perforations into an air cavity. The heated fresh air is then distributed throughout the building by the conventional ventilation system.
The wall also acts as a heat shade preventing the summer's sun from reaching the main wall and conducting the heat indoors.
Solar cladding is being used in larger commercial and institutional buildings to help reduce their heating and cooling costs.
This benefits not just the building owners, but everyone since high air conditioning use pushes up the cost of power for everyone; including those without air conditioners.
