Six Easy Pieces Webinar

"Six Easy Pieces: EPA Guidance for Moisture Control in Buildings" Presented by Terry Brennan and Lew Harriman"
This is a recording of the April 26, 2018, technical assistance webinar Six Easy Pieces: EPA Guidance for Moisture Control in Buildings featuring Terry Brennan and Lew Harriman and hosted by EPA’s Indoor Environments Division. In 2013, EPA published the landmark book Moisture Control Guidance for Building Design, Construction and Maintenance. That publication has since become a standard reference for building planners, architects, engineers and building service professionals. During this 90-minute webinar, two of the many contributors to this publication reviewed and discussed six key points made in the book, showing examples that illustrate the benefits of the EPA guidance, as well as some of the consequences in buildings built in earlier times before they could benefit from that advice.
