The term Architectural Lighting encompasses three main factors. The first is the building’s aesthetic, which is crucial for any commercial, especially retail, environment. The second consideration is ergonomic or functional — any aspect which improves one’s ability to live, work, function, relax or play — to make the space easier to use. The third aspect involves the efficiency of energy, ensuring that light is properly, which is to say economically or optimally, used and distributed.
Architectural Lighting, as opposed to functional commercial or residential lighting is concerned with (spoiler alert) architecture, or furthering the design experience of buildings and other physical structures. Both residential and commercial lighting can also qualify as architectural lighting, though this isn’t always the case. Some lighting is primarily functional and/or exists in a space that no one would call “architectural.”
