What does natural lighting refer to?

Natural lighting refers specifically to illumination by the sun. This type of lighting is derived from the sun's rays, allowing natural light to fill a space without the use of artificial sources. It plays a significant role in design and architecture, as it can enhance the mood of a space, reduce energy costs, and create dynamic environments that change throughout the day.

When considering artificial lighting, which is generated by lightbulbs and other man-made sources, it contrasts with the concept of natural lighting, as it does not utilize sunlight. Similarly, indoor lighting sources can encompass a range of artificial solutions, further emphasizing the distinction between natural and artificial illumination. Therefore, the most accurate representation of natural lighting is the illumination produced directly by the sun itself.
