AbstractThis paper investigates the influence of the variability of measured moisture transport properties on the overall hygrothermal performance of a high-rise construction wall. The analysis was carried out using a state-of-the-art hygrothermal model. The LATENITE model is a two-dimensional heat and moisture transport program tailored specifically for building envelope investigations. For the present simulations, the model was adapted for one-dimensional conditions and hourly simulations were predicted for a one-year performance of a high-rise wall section. Three types of façade cladding were used: two with red brick (one with an extremelyhigh water vapor permeance, one with normal permeance) and one with a sandlime stone facade. Several cases for the wall systems were tested to determine the relative influence of moisture transport properties of the wall on the predicted results.
