A Methodology for Assessment of Building Assembly Air Leakage Moisture Response, Condensation Risk, and Expected Durability When Subjected to Projected Future Climate Loads

Abstract

It was determined that the ability to assess the required performance of an air barrier assembly could now be supported using modern computational hygrothermal simulation techniques coupled with historical and future climate data and the new durability methodology developed as part of the updated 2019 CSA S478 Guideline for Durability of Buildings.
