Space (volumes of air) cannot be lit! The electromagnetic energy known as light is not visible until it hits surfaces and reflects from them or transmits through them. Objects and surfaces are lit to enable occupants to perceive space volume. The principles and techniques discussed in Architectural Lighting Design 3rd Edition (ALD3e) lay the groundwork for creative lighting solutions addressing vision and psyche issues for occupants.
This website is a companion to ALD3e and offers expanded and additional resources for those interested in architectural lighting. As an art and a science, some aspects here relate to design and creativity and others relate to illuminating engineering. Explore and enjoy.
