Abstract
This study evaluates the influence of different cardinal directions considering temperature and rain moisture for facades of buildings located in the city of Santa Maria, Brazil, consisting of solid ceramic bricks or 6-hole blocks coated with cement-based mortars. Based on hygrothermal simulations conducted with WUFI® Pro 6.5 software, the climate agents were analysed, and for each solar orientation, the Iti (thermal intensity index) and the RIF (rain impact factor) were determined, considering moisture intensity due to precipitation. The results indicate that the wall substrate composition, with solid ceramic bricks or 6-hole blocks, did not influence the impact of temperature and rain moisture on the facades’ external mortar coating. However, the results were different according to the cardinal orientations considered.
