Lighting Design

Energy Efficiency and Lighting Design

Efficient laboratory lighting design first considers the task that occupants will perform in the space. We review two lighting design approaches: general lighting and task-ambient lighting. The lighting design approach determines the type of lighting calculation used. Lighting design affects other energy-consuming systems in the facility. For instance, in cleanrooms, large ceiling luminaires reduce ceiling area for HEPA filters. As filter area is reduced, filter exit velocity increases, increasing the static pressure within the system, which causes fans to consume more energy. Finally, all heat generated by the luminaires and the harder working fans affects cooling equipment sizing. [McIlvaine, 1992; Eley et al., 1993]
