Ultra Violet Germicidal Irradiation

alt_text

Description:

With the arrival of COVID, there has been a surge of interest in Ultra Violet Germicidal Irradiation. During our research, the IDL found that UV systems can actually save on operational costs by reducing fan energy. Attendees will learn about the different UV technologies available, the strength needed to kill pathogens in air streams, and how to minimize the energy used to run these systems. This lecture will draw from leading researchers such as William Bahnfleth, who chaired ASHRAE’s Epidemic Task Force. By installing UVGI systems in front of cooling coils, these can help prevent microbial growth and ensure better airflow throughout the building. With building occupants increasingly mindful of airborne contaminates, it’s important for architects and engineers to be aware of these systems and how they can be integrated into a building.

Learning Objective 1: 
After attending this program, participants will be able to articulate the pros and cons of UVGI systems.
Learning Objective 2: 
After attending this program, participants will be able to identify the health benefits associated with using UVGI.
Learning Objective 3: 
After attending this program, participants will be able to estimate the operational costs of operating a UVGI.
Learning Objective 4: 
After attending this program, participants will be able to understand the design differences between in-room and in-duct systems.

Director - Assistant Professor
Biography: 
Dr. Woods is a licensed mechanical engineer who started working at the IDL as a graduate student back in 2013. His dissertation used energy models paired with weather forecasts to predict how a radiant slab should be managed to maximize occupant comfort. His current research focus is on the integration of surface temperatures into building energy management systems. Dr. Woods has taught courses in advanced thermodynamics and energy modeling. In the office, he spends his time working on energy models and estimating savings from energy upgrades; out of the office he is usually fly fishing or gardening. Dr. Woods earned his B.S. from Montana State University, his M.S. from Boise State University and his Ph.D. from the University of Idaho.
