When horizontal surfaces are illuminated, people and activities become the dominant features in a space.
Light is fundamental in architecture.
It affects the usefulness of a building and the enjoyment of a building interior. It also affects the way users feel about themselves and others. For these reasons, the visual impressions induced by the lighting system are fundamental in planning and design, and they become a functional part of the activity. The use of light is an inseparable part of the architectural conception. Many building projects require the help of special consultants to solve complex problems of lighting system design.
