This document is one of the major outcomes from the consortium project called MEWS (Moisture Management in Exterior Wall Systems), carried out at the Institute for Research in Construction (IRC) of National Research Council (NRC), Canada. This report deals with the parametric analyses of four different types of wall assemblies in a building envelope. The four types of walls considered are (1) Stucco walls, (2) EIFS walls, (3) Masonry walls, and (4) Siding walls. The parametric analysis was done using IRC's hygrothermal modelling tool hygIRC. hygIRC is a 2-dimensional numerical modelling tool specifically developed for research purposes and it is continuously evolving at the IRC/NRC. The utility and reliability of hygIRC outputs have been established through laboratory measurements and benchmarking exercises.
