  1. Morning Sun: Your east-facing windows bathe in the morning sun, as it’s the point of sunrise. They soak up the warm, gentle rays during the first half of the day. For example, if you’re an early bird, or if you’ve rooms used mainly in the morning, they’re best positioned on the eastern side.
  2. No Afternoon Sun: East-facing windows do not meet the sun during hot afternoons. As the sun moves toward the west, the direction of sunlight changes, leaving the east side in shadows. Take, for instance, rooms used for midday or evening activities may not benefit from being on the eastern side, given no afternoon sun.

Studying the sun’s movement and understanding its pattern becomes a pivotal factor in managing sunlight exposure in your home. A room’s location relative to the sun’s path determines its amount of sunlight, invariably affecting its brightness and temperature. For instance, a west-facing room gets harsh afternoon sunlight, whereas an east-facing room enjoys soft morning light.

Nevertheless, remember these rules are not rigid. Various factors can influence how sunlight interacts with your home. Topography, obstacles such as buildings or trees, and even latitude can also play roles. It’s always useful to consider these factors when thinking about how sunlight affects your living space.

Every building is different, as are its needs for light and shade. As more residents become conscious of green living, understanding the sun’s path, its effects, and positioning rooms accordingly becomes significant. Therefore, the position of the sun influences the amount and quality of natural light in your home, playing an essential role in your living environment’s harmony and comfort.
