AbstractThis paper focuses on the simulation results of three exterior wall designs in the Beijing climate and how these particular results have been incorporated into guidelines for construction design and on-site building practices in that region of China. The simulation tool is hygIRC-2D. Simulations are conducted assuming (1) vapour diffusion without air leakage, (2) vapour diffusion with various levels of air leakage, (3) rain screens or no rain screens, (4) vapour retarding or normal latex paint over the drywall; and (5) typical interior climatic conditions. The simulation results are processed to provide a variety of graphical information including the RHT index (moisture response indicator) and moisture content readings in wood structural members (upper and lower plates) and wood structural sheathing. Simulation results and subsequent analyses provide guidance on the relative performances and suitability of these assemblies for wood frame construction in the Beijing region and other areas of China with similar climates.
