Tracy Beeson joined PNNL earning a M.S. in Architectural Sciences with a concentration in lighting from Rensselaer Polytechnic Institute, and became Lighting Certified (LC) by the National Council on Qualifications for the Lighting Professions (NCQLP) in 2008. Mrs. Beeson has a considerable knowledge base of general lighting applications and technologies, and has experience in field demonstrations, developing lighting measurement protocols, and establishing best lighting practices to improve energy efficiency for various entities. She also contributed to the development of the National Energy Standard for ASHRAE 90.1-2010. More recently, she has been overseeing the lighting testing efforts for the Solid State Lighting Program, and has been working to coordinate the simplification of data transfer between testing labs and various voluntary and research programs. She is passionate about research and implementation of daylighting and advanced lighting controls while reducing lighting energy consumption without compromising lighting quality of the visual environment.
