Architectural lighting design

Architectural lighting design is a field of work or study concerned with the design of lighting systems within the built environment, both interior and exterior. It can include the manipulation and design of daylight, electric light, or both, to serve human needs. Lighting design is grounded in both science and the visual arts. The basic aim of lighting within the built environment is to enable occupants to see clearly and comfortably. The objective of architectural lighting design is to balance the art and science of lighting to create mood and visual interest, and to enhance the experience of a space or place while still meeting technical and safety requirements.

The purpose of architectural lighting design is to balance the characteristics of light within a space to optimize the technical, visual, and, most recently, the non-visual components of ergonomics with respect to the illumination of buildings and spaces.

The technical requirements include the amount of light needed to perform a task, the energy consumed by the lighting within a space and the relative distribution and direction of light so as not to cause unnecessary glare or discomfort. The visual aspects of light are those concerned with the aesthetics and narrative of the space (e.g. the mood of a restaurant, the experience of an exhibition in a museum, the promotion of goods within a retail space, the reinforcement of a corporate brand) while the non-visual aspects are concerned with human health and well-being.

As part of the lighting design process, both cultural and contextual factors also need to be considered. For example, bright lighting was a mark of wealth through much of Chinese history, but uncontrolled bright light is known to be detrimental to insects, birds, and the visibility of stars.

The history of electric light is well documented, and with the developments in lighting technology the profession of lighting developed alongside it. The development of high-efficiency, low-cost fluorescent lamps led to a reliance on electric light and a uniform blanket approach to lighting, but the energy crisis of the 1970s required more design consideration and reinvigorated the use of daylight.

The New York-based Illuminating Engineering Society (IES) was formed in 1906. A London-based organization established in 1909 with the same name is now known as the Society of Light and Lighting (SLL), a part of CIBSE. The International Commission on Illumination (CIE) was established in 1913. The Institution of Lighting Professionals was established as the Association of Public Lighting Engineers in 1924. Around the world similar professional organizations evolved.

Initially, these industry organizations were primarily focused on the science and engineering of lighting rather than the aesthetic design, but in 1969 a group of designers established the International Association of Lighting Designers (IALD). Other associations purely for lighting design have included the Professional Lighting Designers' Association (PLDA) established in 1994, the Association de Concepteurs Eclairage (ACE) in France established 1995, the Associazione Professionisti dell'Illuminazione (APIL) in Italy established in 1998, the Associação Brasileira de Arquitetos de Iluminação in Brazil in 1999 and the Professional Association of Lighting Designers in Spain (APDI) established in 2008.

Architectural lighting designer is a stand-alone profession that sits alongside the professions of architecture, interior design, landscape architecture and electrical engineering.
