Webinar On-Demand
Sponsored by Huntsman Building Solutions and SOPREMA
Presented by Charles Allen, AIA, George DuBose, CGC, and Donald B. Snell, PE CIEC

Learning Objectives:

  1. Discover through the use of case studies, the hidden risks of mold and moisture damage from poor air barrier design and installation.
  2. Discuss the differences between water barriers, vapor retarders, air barriers, and thermal barriers in a building envelope and understand how to determine their performance in order to avoid water/moisture intrusion and mold problems.
  3. Identify how the HVAC system design could be the cause of your air barrier failure and how it might be contributing to moisture and mold problems.
  4. Analyze multiple building codes and use them to prevent air barrier-related mold and moisture building failures.

Confusion over air leakage standards can pose a real difficulty for designers. Air barrier testing is not always easy and the results can lead to a false sense of security. There should be a way to determine the risk of having a catastrophic mold and moisture problem from an air barrier failure before you design or build your next project. This webinar will be presented by Liberty Building Forensics Group experts George DuBose, CGC; Richard Scott, NCARB, AIA; Donald B. Snell, PE, CMC; and Charles Allen, AIA. This webinar will: use case studies to show exactly how air barrier failures can occur and how to avoid those failures; present the air barrier building codes and standards that are most confusing and discuss how to use them to benefit your next project; and outline a practical way to mitigate catastrophic mold and moisture problems from air barrier failures on your next project.

Charles Allen has emerged as a leader in the industry of building and architecture forensics. His experience and knowledge centers around building envelopes, roofing systems, wall systems and other design issues that can create opportunities for catastrophic mold and moisture failures. Charles has applied his expert architectural knowledge and cutting edge technological skills on some of the largest and most complicated building failure projects in the world, many of which span across multiple construction industries. These include, the 1.2 Million SF Orlando VA Medical Complex, FRHI 2,000+ rooms in Southeast Asia, Disney’s Grand Floridian building envelope refurbishment, and The University of Virginia CAS and ITE building.

George DuBose, CGC, President of Liberty Building Forensics Group, has over 25 years of experience in building forensics, with a focus on mold and moisture issues as well as HVAC and building envelope failures.

Donald B. Snell, PC CIEC, a Senior Forensic Engineer/Vice President with Liberty Building Forensics Group, has over 25 years of experience with the design, cost analysis, and technical nuances of HVAC systems. He has used diagnostic and remedial solutions to help some of the largest commercial builders in the world with catastrophic moisture and mold intrusion resulting from HVAC failure.
