This course covers the technical aspects of design buildings that work, with a focus on the building enclosure (called the “envelope” in the past). The course advances beyond Arch 364 in depth and scope. The emphasis is on the practical technical needs of architects specifying, designing, and detailing building enclosures -- walls, windows, roofs, foundations etc. Although typical modern Canadian architectural practise is the primary concern, which means cold climate commercial, institutional, and high-rise residential occupancy, building in other climates and contexts (e.g., Dubai, Houston, Shanghai, Las Vegas) will be compared and contrasted. There will be a bias towards buildings with the high performance goals required by new energy regulations and owners seeking low- and net-zero-energy buildings as well as low-embodied carbon materials. Minimum performance expectations required by codes will be identified however.
