Windows are typically named the "weakest link" in the building envelope; to have the biggest impact on the overall building performance, window specifications should be carefully considered. This session will focus on the most effective strategies for improving window and door performance, including the use of insulated frames, selective glazing by orientation, compression rather than sliding seals, window-to-wall ratios, and occupant considerations such as comfort, and access to natural lighting and ventilation.
Learning Objectives:
-Understand the effect of insulated frames and Low E type on overall U-values
-Recognize the trade-offs between U-values, solar heat gain coefficients, and visible light, particularly in a cold climate region
-Recognize opportunities for passive solar glazing and the use of walls of glass for south-facing elevations
-Note the appropriate uses of different Low E types depending on building orientation, and other factors such as overhangs, deciduous trees, room size, and window size
-Note modern day materials for insulated glass spacers and their advantages and disadvantages
-Understand the pros and cons of different operable window styles
-Consider window-to-wall ratios in context of the quality of the living environment, and the overall performance of the building
-Understand the new building code requirements through NAFS (North American Fenestration Standard)
