Course Overview

Water and moisture damage in buildings occurs all too frequently. The results can be disastrous, and corrective measures can be difficult and extremely costly. Moisture and water damage-related building failures can also result in costly construction claims. This course will improve the knowledge and skills of individuals in design, installation, maintenance, and repair of moisture control components and systems for all building types. 

Who Should Attend?

  • Architects 
  • Engineers 
  • Contractors 
  • Facility owners and managers 
  • Building envelope commissioning authorities

Lew Harriman

Lew Harriman is the Director of Research & Consulting at Mason-Grant. Much of his work over the last 30 years has concerned humidity and moisture control in buildings and industrial processes, along with related phenomena which are affected by humidity and moisture, such as indoor mold, HVAC systems and the drying rates of materials and structures. Lew has served as a National Peer in the Construction Excellence Program of the Public Buildings Service of the U.S. General Services Administration. He is well-known as a writer and lecturer in North America, Europe and Asia. In 2009 he was elected Fellow of the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE).

Joseph Lstiburek

Joe Lstiburek, PhD, PEng, is a forensic engineer who investigates building failures, and an internationally recognized authority on moisture-related building problems and indoor air quality, including rain penetration, air barriers, vapor barriers, air quality, durability, and construction technology. He is the former chairman of ASTM E241–Increasing the Durability of Building Assemblies from Moisture-Induced Damage and a reviewer of Chapters 21 and 22 of ASHRAE Handbook of Fundamentals. He is an ASHRAE fellow and member of ASHRAE 62.2–Ventilation for Acceptable Indoor Air Quality. He has appeared on PBS’ NOVA (“Can Buildings Make You Sick?”). He is the author of the US Department of Energy Handbook on Moisture Control and a special contributor to the EPA guidance document on Building Air Quality: A Guide for Building Owners and Facility Managers.
