Skylights, green roofs, balconies, courtyards, nature walks, theatres, fountains, and other amenities abound. However, less obvious but critical to the comfort and health of seniors are warm interior floors adjacent to exterior walls and doors, and mould-free air recirculating within the sealed building envelope.

Various regions of North America have witnessed these scenarios in the past two years and there was an impact to the construction industry.

Wind-driven kinetic façade systems add dynamic movement to building enclosures and wall systems. Responding to air currents, the flapper-panel design creates the look of rolling waves across the wall. Suitable for both small- and large-scale projects, popular applications include transit and parking facilities, cultural institutions, entertainment venues, and artistic installations.

Since roll-formed and laser-welded steel methodology is relatively new for curtain walls, this article addresses three relevant inaccuracies as they relate to Canada’s snow-laden winters, subarctic temperatures, and the Leadership in Energy and Environmental Design (LEED) v4.1 goals.

The proper selection and placement of vapour-impermeable materials within wall assemblies is fundamental to their durability in both cold and warm climates. Failure to correctly account for the impacts of vapour diffusion can lead to damage and premature failure of wall assemblies.

Raked joints are commonly used in masonry walls for esthetic purposes. A widespread opinion is they reduce the fire resistance of concrete masonry. However, full-scale experimental tests and numerical studies have now found the fire resistance of walls does not greatly depend on the thickness of the mortar.

Detailing parapet and soffit assemblies requires an understanding of structural building movement and, thermal performance requirements, air control, material limitations, and construction technologies, along
with trade co-ordination.

Several factors influenced the design of the new Arc’teryx flagship store in Vancouver, but all led to the prominent use of zinc on the exterior. The retail chain, founded by local climbers in 1989, offers high-performance outdoor equipment and clothing. Custom titanium zinc panels, installed on a diagonal façade along with granite to symbolize the nearby mountain horizon, highlight the retailer’s largest Canadian store.

When selecting air barrier products to employ in building designs, architects have a broad range of choices. Spray foam insulation products are often selected because they can provide superior performance and also contribute to greater energy and operating cost savings in buildings.
