How Orientation Affects Cooling Costs

South orientation in Mandeville means long, high-angle sun for most of the day, especially from late morning through late afternoon in summer. East-facing rooms heat early because low morning sun punches straight through glass at a shallow angle. Out of all orientations, west is the most punishing for cooling because it combines low sun angles with a house that has stored heat all day. North windows bring soft light and, in summer, the least heat gain, but in Mandeville’s climate the cooling penalty from north glass is usually minor compared to east or west.

Choosing the Right Glass and Frames

The fastest path to lower cooling bills is to treat orientation like a priority list, west and east first, then south as needed.
