Why Window Orientation Matters

Window orientation strongly affects daylight, comfort, and energy performance in a home. This guide explains how north, south, east, and west exposures change light quality, solar heat gain, glare, and seasonal comfort in Canadian climates. It outlines which rooms typically benefit from each orientation, plus practical strategies to reduce summer overheating and winter heat loss using shading, landscaping, and ventilation planning. It also covers how to match glazing choices to each facade, including low e coatings and solar control glass, and why orientation can influence the long term durability of window materials. By combining smart layout decisions with the right glazing and proper installation, homeowners can improve comfort while lowering heating and cooling demands.
