Description
Course Overview
This session was originally presented at the 2025 IIBEC International Convention & Trade Show in Orlando, Florida. This course includes the following components:
- recording of the live session
- a summative assessment consisting of 10 multiple-choice questions
- two surveys required to claim continuing education credit
Description
The presentation examines a failed roof/ceiling assembly with respect to interstitial condensation. A theoretical model is discussed and used to compare to a real-life failure. Once boundary conditions were established, the model was used to examine what would happen if different layers were altered/added to the failed assembly. The intended audience will be proficient in hygrothermal design. However, this session will also be of interest to consultants, designers and contractors who wish to avoid this type of failure. The information presented demonstrates the use of hygrothermal analysis software and how this software can be manipulated to obtain a greater understanding of interstitial condensation problems. Furthermore, the use of a European Standard (ISO EN 13788) is presented to show that the initial failure could have been avoided.

Objectives
At the conclusion of this session, participants will be able to:
- Identify an interstitial condensation problem and what to look for in their own future investigations.
- Discuss the forensic process used in a failure analysis of a roof/ceiling assembly.
- Explain the process of calibrating a model to extract boundary conditions from a failed design and examination of alternative options to rectify the problem through modeling.
- Explore a European Standard technique that could be adopted in their own practice.
Certificate
