Universidad de Zaragoza (orcid)0000-0002-3776-9791 Assessment of water penetration risk in building facades throughout Brazil 2017 Access copy available to the general public Unrestricted The penetration of atmospheric water (rain) into facades creates problems for building habitability and the durability of construction materials. This study analyses the exposure of Brazilian facades to the two main climate factors responsible for this penetration: wind-driven rain and driving rain wind pressure. Daily weather records (spanning 2005–14, from 171 weather stations) were analysed. Both exposure factors were combined to assess the risk of water penetration at each site. The relationships between the different exposure indices calculated from daily, monthly and annual records were determined and compared with results from other countries. From this analysis, detailed isopleth maps are provided that allow a graphical characterization of the moisture exposure conditions of facades anywhere in Brazil. A comprehensive characterization of the water penetration exposure in Brazilian enclosures is created and can be used to establish normative design requirements for actual climatic conditions in each area of the country. In general, an increased risk of penetration was identified in the flat areas of the South and Northeast regions of the country. The sites located in the Amazon basin present comparatively lower risks, despite a greater amount of rainfall, because the wind intensity is less in these inland areas. info:eu-repo/semantics/openAccess by-nc https://creativecommons.org/licenses/by-nc/4.0/deed.es 3.468 2017 CONSTRUCTION & BUILDING TECHNOLOGY 11 / 62 = 0.177 2017 Q1 T1 1.141 2017 Civil and Structural Engineering 2017 Q1 Building and Construction 2017 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Pérez-Bella, J.M.
