Energy Efficient Building System Solutions for Pathogen Reduction (COVID-19, Legionella and Molds)

As pandemic restrictions subside and more people begin the return to public life and public workspaces, building owners, operators, energy managers, and occupants are confronted with the challenge of an increased need to ensure safe, healthy, and comfortable indoor environments. The IAEE and the IAMU have partnered to provide a series of webinars that address energy efficiency and building systems solutions to combat the challenges of COVID-19 and other indoor air quality and general pathogen concerns. IAEE and IAMU are offering four, 1-hour online sessions conducted over 4 weeks, free of charge.  Attendees will have the opportunity to earn up to four continuing education units on a host of topics. Each session is offered twice so you can select the date that works best for you. More details about each session are provided below. We hope that this series will provide you a foundation to build on as we work to address energy efficiency and decreased pathogen levels in our work environments.


Ultraviolet Light Germicidal Irradiation

View Recording

This presentation addresses how ultraviolet light systems can contribute to the reduction of COVID-19 and other viruses and bacteria within buildings. Attendees will develop an understanding of the development of UV systems, how they contribute to improved indoor environmental quality, and different applications of the technology. The presentation will also address odor control and pathogen alert monitoring.


Efficient Water Heating Solutions for Building Heat and Domestic Hot Water

View Recording

Water heating solutions are critical to controlling the proliferation of infectious disease and bacteria. This presentation addresses how condensing water heating systems can provide better water heating capacity while improving efficiency performance.


Cooling Towers Solutions to Combat Microbial Growth

View Recording

Cooling tower design and system maintenance play a significant role in reducing the growth of bacteria and play a significant role in preventing Indoor Air Quality (IAQ) issues. This presentation will cover cooling tower systems basics, materials of construction, design considerations and how systems can reduce or prevent the growth of legionella bacteria.


Fresh Air Solutions to Combat Transmission of Infectious Disease

View Recording

Dedicated Outdoor Air Systems (DOAS) play a significant role in increasing IAQ and Energy Recovery. As buildings reopen, an emphasis is placed on reducing exposure to disease, including viruses and bacteria, through increased outdoor air volume. This presentation will introduce attendees to DOAS systems, discuss the types of equipment, and typical applications for the system.
