In Canada, known for its cold climate, there is great potential to use vacuum insulation panels (VIPs) for exterior building envelope construction. The introduction of Canada’s 2015 national energy code for buildings has made VIPs a very attractive choice for designers and builders. This new energy code aims to achieve about 25 % less energy use in buildings than the 1997 version of the same. The code changes and Canada’s cold climate have increased interest in better building insulation in general and in VIPs in particular. VIPs have thermal resistance values much greater (5 to 10 times) than those of conventional thermal insulation materials. In the Yukon, VIPs have been used as thermal insulation in two applications where thermal performance monitoring is in progress: (1) in a retrofit of a commercial building and (2) in a new home. This paper summarizes results from the temperature monitoring in the commercial building. These field thermal performance monitoring results, observations, and the lessons learned are presented to help the building enclosure construction community in Canada, and researchers, designers, and end-users around the world, to make the best use of the unique properties and performance of VIPs.
