Cape Breton Regional Hospital

Sydney, Nova Scotia

Constructed in 1992, Cape Breton Regional Hospital features a large number of windows designed for optimal thermal performance and resistance to wind, rain and snow. All of the units were built to Canadian Standards Association (CSA) specifications with oversight from Toronto building envelope consultant Michel Perreault.
 
Alantech Extrusions of North Sydney, Nova Scotia, manufactured the windows featuring Quanex’s Super Spacer® warm edge spacer system. According to Perreault, "As soon as you design for an outside temperature lower than -15°C, you can't really hope to achieve even 30-35% RH on the inside without condensation—unless you're prepared to go to warm edge technology."
 
A decade later, and with some areas requiring up to 50% RH, project manager Derek Fletcher comments, "I can tell you that the windows have performed very well. Not a single instance of condensation has been reported to me."
