Presentation Description:

Although many have just accepted the chances of catching COVID, the costs of transmission are still high for those who are immunocompromised, at-risk seniors, and healthcare workers.  Additionally, besides COVID, the productivity and absenteeism due to flu season impact every business and school.  One tool in the arsenal has been little utilized: UV for occupied spaces.  Battle tested since the 1930s in combatting tuberculosis, upper room UV is officially recognized by ASHRAE as a recommended method for controlling airborne transmissible diseases but is still little known.

In this session, a UV consultant and researcher will share knowledge on how upper room UV is an attractive and cost-effective way to control viral and bacterial spread in occupied rooms.  Furthermore, new advances in Far UV, which is safe for skin and eyes and therefore can be used wherever normal light fixtures are installed, will be shared. 

Attendees will learn:

  • The working principles behind upper room and Far UV
  • Appropriate applications for UV technologies compared to filtration or additional ventilation
  • Safety considerations and how to respond to queries about ozone generation and skin/eye concerns
  • Performance and safety standards in the market
  • Sample installed costs relative to other technologies
