Substitution of daylighting for electric lighting in a large office building
Analysis of the energy use of large office buildings reveals the dominance of lighting as the major energy use category, requiring up to 60% of the total energy consumed by a building in a mild climate like California's. With the application of passive solar design strategies to this type of building, the importance of daylighting as a means of reducing its annual energy use is underscored. An energy sensitive design process is applied to a large (600,000 sq. ft.) engineering office building located in the San Francisco Bay Area of California. The use of daylight as a substitute for electric lighting was identified as a strategy for increasing the energy efficiency of the building as well as improving the visual qualities of the work environment. Results of a model/simulation testing program indicate that the proposed design can contribute up to 75% of the ambient lighting in the work area. To enhance the visual satisfaction of the workers, a task-ambient lighting concept combining daylighting, indirect fluorescent lighting, and individual task lights at work stations will be deployed.
