Building Envelope 1 addresses the design and performance of building envelope assemblies with a focus on above grade assemblies including walls, roofs, doors and fenestration assemblies. By the end of the course, the students will have developed a good knowledge of the theoretical and practical aspects of the design and the likely performance of the whole Building Envelope. Topics include: The definitions and functions of building envelope assemblies and how they affect and are affected by the function and performance of a building as a whole. An overview of materials and methods commonly used in the construction of building envelope assemblies in Canada with some reference to other locations and climates. The driving forces and mechanisms to control heat flow, air leakage, rain penetration and moisture transport by vapour diffusion and capillary action including an introduction to the use of computer-based thermal and hygrothermal analysis tools (e.g. THERM and WUFI). Designing walls, roofs, door and fenestration assemblies for durability with due consideration of hygrothermal loads such as rain penetration, heat loss, vapour diffusion, air leakage, and condensation, material properties, damage functions that affect building envelope assemblies and how to minimize degradation by design and material selection. Methods to analyze thermal bridging at 2D and 3D building envelope details. Overview of the requirements of the applicable Building Codes and Standards (National Building Code of Canada, British Columbia Building Code, Vancouver Building By-Law, Ashrae 90.1, etc.) with respect to building envelope performance and durability. 2D and 3D building envelope details pertaining to moisture, air, and heat management, with the specific focus on the "continuity" of the building envelope control layers (rain penetration control, thermal insulation, air barrier, and vapour retarder/barrier) within building envelope assemblies and at transitions to adjacent assemblies.

Upon successful completion of this course, the student will be able to:
- Design the primary wall, window, roof, and balcony systems for low-rise, medium and high-rise buildings using acquired knowledge of building physics, building codes, available research and of best practice guidance, and their own professional judgement.
- Calculate, to the appropriate level of accuracy, the hygrothermal response of the wall, window, roof systems by applying computer-based analysis.
- Diagnose problems in walls, roofs and fenestration assemblies using analytical methods and building science principles,
- Recommend procedures – both quantitative and qualitative – towards achieving the necessary building envelope performance.
- Communicate the rationale, options and recommendations for design choices
