When assessing a space for lighting design, evaluating natural light sources first is crucial because they play a significant role in determining how the overall lighting scheme will function. Natural light not only affects the ambiance of a room but also can reduce energy costs and influence the choice and placement of artificial lighting. Understanding where and how much natural light enters the space helps in planning the balance between natural and artificial light, which is essential for creating an effective and comfortable lighting design.

For instance, if a room has large windows that let in plenty of sunlight, the lighting design may lean towards less artificial light during the day. Conversely, in a room with limited natural light, additional fixtures and brighter bulbs may be necessary to ensure adequate illumination. By evaluating natural light sources first, a designer can make more informed decisions about artificial lighting solutions that will complement and enhance the available daylight, ultimately leading to a more harmonious and functional lighting design.
