Lighting in Federal High-Performance Green Buildings

In 2013, the U.S. General Services Administration (GSA) awarded a contract to the Light and Health Research Center (LHRC). The project focused on the correlation of daylighting with health and well-being, assessed the building occupant experience of light, and looked to identify health outcomes linked with measured light exposure in Federal High-Performance Green Buildings.

LHRC researchers used the Daysimeter, a calibrated, personal light and activity sensor that continuously records and stores data for measuring circadian light (circadian stimulus or CS). LHRC researchers also conducted photometric measurements to assess the potential for CS in the buildings.

Current research involves field testing novel luminaires developed by the LHRC to promote circadian entrainment and alertness in the office environment.

Several buildings were evaluated during different seasons.
