Solar heating and ventilation systems that perform like heaters but resemble conventional metal cladding are improving indoor air quality, saving money, and reducing energy costs for schools across North America. Years of research have facilitated a completely new approach to solar heating; an approach that is simple, inexpensive, highly efficient, and can be seamlessly integrated with many architectural styles. The transpired solar collector systems are similar to other metal walls, and posses all the benefits of metal cladding, such as strength, durability, and aesthetic versatility, yet they also have the additional advantages of improving indoor air quality while decreasing energy bills and CO₂ emissions.
