Break from the Mold: Hygrothermal Analysis of Building Enclosures

Break from the Mold: Hygrothermal Analysis of Building Enclosures

Many construction claims are due to moisture-related issues. While most of these claims are related to liquid water leakage, a growing fraction can be attributed to condensation and microbial growth, particularly as our enclosure assemblies become more complicated and less “breathable.” As our understanding of these issues and their consequences grows, it is imperative that enclosure designers recognize the mechanisms that cause microbial growth, not only to identify them during investigative work, but to avoid them in design. In this webinar, we will discuss hygrothermal properties as they pertain to building enclosure performance. We will cover basic fluid- and thermo-dynamic principles, relevant codes and industry standards, qualitative factors that influence design and performance, and analytical measures that can be used to quantify the risk of moisture intrusion.


After attending this webinar, participants will be able to:

  • Understand basic hygrothermal principles and how they pertain to building enclosure performance.
  • Discuss how codes and standards inform hygrothermal analysis of building enclosures.
  • Determine qualitative performance typical of environmental design conditions.
  • Identify project-specific factors that influence design decisions and use quantitative analytical measures to confirm or analyze performance.

Participants will earn 1.0 AIA CES Learning Unit (LU/HSW) for attending the live webinar. Registration is free. Please note that space is limited – email events@sgh.com to join our waitlist if the session is closed when you register.
