Essay:
HAM: MOISTURE-EXPERTIn this activity, the ORNL MOISTURE-EXPERT hygrothermal model (Karagiozis, 2001) was employed in developing a parametric analysis of the performance of permeable wall systems without mechanical ventilation. A series of 2-D simulations were performed. The 2-D simulations allowed us to determine the hygrothermal performance of the walls with the influence of infiltration/exfiltration air dynamics. In these 2-D simulations, the influence of air flow through the wall system was evaluated as a function of hourly wind pressures. As 1-D simulations do not include air flow dynamics in walls, a decision was taken to limit the number of simulations conducted, but to carry out all the simulations in 2-D. In Table 1 a review of the parametric analysis is given. This decision was beyond the initial intent of the project, as 1-D simulations were proposed.
