A House Is Not Always A Home 〰️

The Urbandale Center for Home Energy Research is a joint venture between the School of Engineering and the Azrieli School of Architecture at Carleton University. Built in 2015 on campus grounds in the form of a typical gable-roofed house, the facility conducts long-term explorations into various methods of increasing building performance and reducing reliance of Canadian housing on conventional energy sources.

The Center combines Passive Solar Heating with a highly flexible wall assembly system using Vacuum Insulated Panels (VIPs) as primary source of insulation, achieving a performance R-value of 50 for every sing inch of thickness. The exterior cladding assembly is unitized, composed of units of reclaimed wood strapping hung onto steel Z-girts, which are in turn fastened to the structure through Cascadia Fiberglass Rainscreen thermal spaces. This allows for a generous cavity between the envelope and the structure of the building, where various exercises in insulation and passive solar heat gain can be conducted.

A double-layered VIP paneling system was devised to allow for the entire surface of the building envelope to be covered while working around the location of the rainscreen clips and windows. Both layers follow a separate grid, and together they give the walls an average of 99.3% insulation coverage.
