Lighting design is an essential aspect of interior design but very few universities offer students the opportunity to study lighting design in depth as part of their Council for Interior Design Accreditation (CIDA)-accredited undergraduate interior design program. This paper makes a case for including lighting design as an indispensable part of interior design education while also promoting the Family and Consumer Sciences Body of Knowledge (FCSBOK). The rapid and ongoing advancements being made in luminaire design, lighting controls, and energy conservation necessitate attention and expansion of lighting design education within interior design programs.
