Windows do not count as indirect sunlight. When light passes through a window, it is still considered direct sunlight. However, it is important to note that the intensity and quality of the sunlight may be altered as it passes through the window.
The concept of indirect sunlight refers to light that is diffused or reflected before reaching a surface. This can occur when sunlight bounces off other objects or surfaces before reaching the desired area. In such cases, the intensity of the light may be reduced, and its direction may be changed.
In contrast, when sunlight enters through a window, it is generally considered direct sunlight because it travels in a straight path from the sun to the window and then into the room. The window acts as a medium through which the sunlight passes, but it does not significantly diffuse or scatter the light.
However, it is worth mentioning that the characteristics of the window itself can influence the quality of the light that enters the room. Different types of windows have varying degrees of transparency, reflectivity, and ability to filter certain wavelengths of light. For example, frosted or tinted windows may alter the color or intensity of the sunlight that passes through them.
Furthermore, the orientation and location of the window can also affect the directness of the sunlight. South-facing windows, for instance, may receive more direct sunlight throughout the day compared to windows facing other directions. Additionally, obstructions such as trees or buildings outside the window can partially block the sunlight, resulting in indirect or diffused light.
In my personal experience, I have observed that the sunlight coming through a window can vary depending on the time of day, weather conditions, and the window’s characteristics. On a clear day, the sunlight entering through a window can be quite bright and direct, casting distinct shadows in the room. However, during cloudy or overcast days, the sunlight may appear more diffused and less intense.
While windows allow direct sunlight to enter a room, the characteristics of the window itself and external factors can influence the quality and intensity of the light. Therefore, it is important to consider these factors when assessing whether the light passing through a window can be categorized as direct or indirect sunlight.
