GUV: Pandemic fad, or game-changing technology for healthy and more energy-efficient buildings? (No CEU)

About this Course

The IES offers Educational Webinars throughout the year, purposefully spanning a broad range of topics and speaker expertise. 

Description: Though the worst impacts of the pandemic are over, illness and absenteeism resulting from airborne viruses continues to cost U.S. businesses over $200B annually, reduce student learning and achievement, and exacerbate public health and education inequities. As the building industry considers how to address these costs, ASHRAE has committed to develop a new building design standard to reduce airborne disease transmission. Evidence is growing that germicidal ultraviolet (GUV) disinfection technology is among the most effective and energy-efficient methods to reduce transmission. This webinar will provide a fresh look at GUV technology, sharing new research on its effectiveness and energy use relative to other methods, as well as results from CALiPER product performance testing and field evaluations getting under way. 

The Illuminating Engineering Society (IES), in collaboration with Pacific Northwest National Laboratory (PNNL), is pleased to offer a special, five-part, free webinar series on “Big Questions” in the lighting industry today. Advanced lighting systems can provide improved occupant health and productivity, better control, increased use of data, all with more sustainable product design. At the same time, new capabilities raise a host of questions with significant energy and environmental implications. Lighting researchers tackle big questions, and this webinar series will share the latest perspectives from PNNL experts and partners in pursuit of the best answers.
