For people who spend a big part of their day or their whole day in places like offices where the natural light sources are scarcely and artificial sources are heavily used, lighting is the most determining factor in performance. Therefore, nondistracting lighting designs similar to sunlight must be used.
Projects that directly aim productivity and health principles such as Human Centric Lighting provide an important advantage in office lighting. Offices form large spaces and can have many spaces that are used for different purposes such as working, resting, having meetings, and eating. The lighting design of these places must be different and goal-oriented. Additionally, luminaires with various color intensity and temperature must be selected for spaces with different purposes.
