Matt Risinger chats with Lew Harriman, from Mason-Grant Consulting, at Building Science Summer Camp in Westford, Massachusetts. Lew co-authored the EPA's Moisture Control Guidance for Building, Design, Construction, and Maintenance. Lew refers to the handbook as a "series of good ideas, as organized by the EPA. The handbook, which is free to the public, is a great starting point for education on building science with respect to controlling moisture in buildings. Watch the full video to see why this handbook is vital and maybe even life-saving for the builders in the world. The Moisture Control Guidance for Building, Design, Construction, and Maintenance handbook is available for download from the EPA. http://www.epa.gov/iaq/pdfs/moisture-control.pdf.
