New and Underutilized Technology: Integrated Daylighting Systems

The following information outlines key deployment considerations for integrated daylighting systems within the Federal sector.


Integrated daylighting systems can be combined with electronic dimmable fluorescent ballasts, photo sensors, and occupancy sensors where appropriate. Network components, workstation controls, and building management options can also be integrated to provide significant savings on applied systems.


Integrated daylighting systems are applicable in perimeter and interior spaces with daylight exposure via windows and skylights.

Key Factors for Deployment

Acceptable levels of daylight are required and must be factored into deployment.
