Course Length: 3 hours

Companion Course: Humidity Control II: Real-World Problems and Solutions

In commercial buildings, excess humidity and moisture promotes mold, mildew, and uncomfortable conditions for occupants. This course, based on ASHRAE’s Humidity Control Design Guide for Commercial and Institutional Buildings and on the ASHRAE Guide for Buildings in Hot and Humid Climates, helps the designer achieve true control of humidity, rather than just its moderation. The course covers how to understand and easily estimate the major humidity loads that must govern the design of the system and how to make decisions about equipment size and configuration. Attendees will learn what equipment is used for this purpose, how it works, and how to apply it quickly, economically, and reliably.
