Fundamentals of Ultraviolet Germicidal Irradiation (UVGI) for Air and Surface Disinfection

Course Length: 3 hours

A comprehensive introduction to how ultraviolet germicidal irradiation (UVGI) can be used in conjunction with HVAC systems to improve indoor environmental quality (IEQ) and reduce airborne disease transmission is the focus of the course. The course surveys the history of the development of UVGI from its beginnings in the 19th Century to the present. The course describes the fundamentals of the germicidal action on UVGI and characteristics of UVGI sources, common system types and their applications, the economics of UVGI, and practical considerations including material degradation, maintenance, and safety. Case studies are used to illustrate typical applications.
