The Cold Climate Housing Program (, CCH) is an information and education program within the Department of Bioproducts and Biosytems Engineering that promotes the idea of the “house as a system.” This means that the building structure (known as the envelope), the mechanical systems in the house and the occupants are interactive and work simultaneously. A change in one part of the system will always affect others. By recognizing and respecting this system approach, we can enhance the performance of our houses. – University of Minnesota, St. Paul, MN
