| Summary: | Deterioration of
building envelopes due to poor moisture management is considered critical in the
sustainability of buildings where wood-frame constructions are widely used.
However, the integration of research outputs in building enclosure design
analysis considering the combined effects of internal and external parameters
is less exhaustively explored. This is partly due to the uniqueness of each
component material, the uncertainty of involved factors, and complex
interdependencies that influence the response of building envelopes throughout
their service lives. To address this issue, hygrothermal simulations and risk
assessment of key moisture indicators were performed on wall assemblies exposed
to different climatic conditions. The assessment focused on three major issues
concerning the moisture design of exterior walls: (1) selection of appropriate
materials for optimum performance, (2) effect of moisture infiltration, and (3)
different geographic locations. The proposed design methodology includes the
simulations and development of a design experiment method based on
full-factorial design. The proposed method demonstrates a quantitative appraisal
resulting in a clear presentation of moisture accumulation, considering
dependencies on various factors. Research findings showed several important
factors that affect the hygrothermal performance of wood-frame wall assemblies
and need to be considered in the design process. The relationship with the
external climate determines the optimal moisture response, given the dependency
of the component properties on the drying and wetting potential. |
