Assessment Method for Combined Heat, Air and Moisture Transfer in Building Components

The present state of knowledge, concerning heat, air and moisture (HAM) transfer through construction elements demands updating. The standardized Glaser method for calculation, prediction and evaluation of moisture performance is frequently used to assess the moisture safety of structures but is considered as rarely applicable. The method has a lot of limitations and as a result, construction elements that are qualified as good moisture design may in reality, due to built-in moisture, precipitation and air exfiltration face many problems. With the recent advances in analytical and experimental knowledge, the prediction of the HAM response of structure has come closer to reality. In this article a review of the acceptable tools based on HAM transfer is made.
