Optimizing Circadian Stimulation in the Workplace

Illuminate your knowledge of the health benefits of using light in design.


As humans, we're biologically programmed to experience bright days and dark nights—but in the built environment, our light exposure has dramatically changed. This course will share results from GSA’s implementation of circadian light practices in federal buildings and demonstrate the potential health benefits of improving exposure to daylight in buildings.

Learning objectives

  • Identify the key dimensions of the circadian system, and how it is affected by light characteristics, including spectrum, intensity, and the daily light/dark cycle.
  • Evaluate an indoor space for its circadian stimulus potential using different analysis workflows.
  • Collaborate with architects, interior designers, building occupants, and others to integrate circadian stimulus into space design, organizational practices and building operations.
  • Assess different lighting options, including both daylight and electric lighting, and select the suite of solutions to implement for optimizing circadian stimulation.
