Simulation model hygIRC is an advanced hygrothermal model that has been developed at the Institute for Research in Construction (IRC). It is an enhanced version of the ¡°LATENITE¡± model developed jointly by IRC and the VTT (Finland) (Salonvaara and Kara- giozis 1994, 1996; Karagiozis et al. 1995; Karagiozis and Kumaran 1997)
CMHC CURRENT HOUSING RESEARCH, Volume 8 Number 1 Summer 2001
Modeling of Air/moisture Movement and Durability Performance of Residential and Commercial Buildings
The purpose of this project is to develop knowledge to assess the impact of various wall design and indoor-outdoor environmental conditions on the durability and energy efficiency of new and retrofitted high-rise residential and commercial building systems. The hygIRC heat, air and moisture model developed by the Institute for Research in Construction is being used to model common wall systems. Retrofits to improve the airtightness and insulation levels in the walls were developed and are being applied to the basic wall systems. The hygIRC model will simulate heat, air and moisture conditions within the retrofitted walls to determine how the retrofits affect the durability of the wall system. This information will be used as a means to confirm the integrity of several specific retrofit measures developed for high-rise wall structures before they are recommended to the building industry.
