AIA Approved Continuing EducationEnvelope Failure: A Better Weatherization Design


Course Description

Building homes that are well protected from the weather should be a priority for any building professional. The majority of problems stem from improper procedures and workmanship, but often the problem is found in the design of a home.  This three hour continuing education offering will explore factors that contribute to exterior shell failure, and identify practical solutions that will preserve the integrity of the building envelope.


After completing this course participants will be able to:

  • Identify the components of the building as a system, its performance requirements, and how these features must be integrated to prevent building envelope failure. 

  • Describe how a properly constructed building envelope will keep out weather related moisture and stop uncontrolled movement of energy due to loss of conditioned air.

  • Outline at least one design strategy based on “best practices” for the construction of buildings in areas with relatively high humidity.

  • Summarize the options available to the consumer that may have been injured by, or suffered a financial loss by construction defects and the resultant failure of the building envelope.
