When you're building, positioning windows to maximise winter sun and minimise it in summer is one of the most cost-effective ways to improve comfort.
Getting window placement right allows the home’s layout to work with the sun, not against it. It’s important to consider what direction windows will face, their size, how many there are, and how much sun and heat they will let into the home.
In a high performing home, the goal isn’t to eliminate glazing, it’s to balance daylight, views, and performance. An experienced designer understands how to achieve that balance so the home feels comfortable year-round, and here's how each orientation plays a role:
- South-facing windows bring in very little direct sunlight and are best kept small.
- West-facing windows should be used sparingly. Afternoon sun is low, intense and difficult to shade, making west-facing rooms prone to overheating.
- East-facing windows receive only short-lived morning sun and little winter warmth, so keep them modest in size and number.
- North-facing windows are your greatest asset. When sized and shaded correctly, they provide free winter warmth without causing overheating in summer.
