In commercial buildings, excess humidity and moisture problems have caused difficulties with mold, mildew and uncomfortable conditions for occupants. This course, based on ASHRAE’s Design Guide for Humidity Control, will help the designer achieve true control of humidity rather than just its moderation. The course will cover how to remove moisture loads with equipment dedicated to that purpose alone, rather than relying on the occasional dehumidification effect of a building’s cooling system. Attendees will learn what equipment is used for this purpose, how it works and how to apply it quickly, economically and reliably. Additionally, the material includes an in-depth discussion of moisture load calculations and how humidity control can be added to HVAC designs for different types of commercial buildings. The course also covers the effects of different humidity levels on thermal comfort, corrosion, mold growth and airborne microorganisms-information which helps the owner and designer define the humidity control level that will be optimal for each application. If you need to understand the effects of humidity control as well as how to accomplish it, this course puts you on the fast track to such understanding.
