AbstractField monitoring of the dynamic heat transmission characteristics through Insulating ConcreteForm (ICF) wall assemblies was undertaken in 2009-2010 at National Research Council Canada?s Institute for Research in Construction?s (NRC-IRC) Field Exposure of Walls Facility (FEWF). The main objective of this research is to evaluate the dynamic heat transmission characteristics through two mid-scale ICF wall assemblies in FEWF for a one year cycle of exposure to outdoor natural weathering conditions. The scope of work included the design of the experiments, installation of test specimens, commissioning of the instrumentation, operation of the test facility, monitoring, and data collection & analysis. The present NRC-IRC?s hygrothermal model, called hygIRC-C, was used to interpret the readings of the instrumentations and to improve the experiment design by repositioning these instrumentations at critical locations. Subsequently, the present model was benchmarked against the measured data. Results showed that the predictions of the present model are in good agreement with experimental data. This research is on-going. Future work will be presented in later publications where the present model will be used to conduct numerical simulations in order to investigate the transient thermal response of full-scale ICF wall assemblies subjected to different Canadian climates.
