Solid state lighting (SSL) opens new opportunities and challenges for designers due to the unprecedented extent of controllability in both the intensity and color of artificial light. New regulations and laws for building construction and retrofits require utilizing energy savings throughout the building, including lighting. Introducing more daylight into buildings can help save energy, is typically desired by occupants for well-being reasons, but can also lead to additional challenges in regard to increased glare, solar gain and color mismatch compared to light from artificial sources. After describing daylight characteristics, a dynamic lighting system for improved comfort level will be shown.
