Universidad de Zaragoza (orcid)0000-0003-4278-6622 A comparison of methods for determining watertightness test parameters of building façades 2014 Access copy available to the general public Unrestricted Watertightness tests allow evaluating the performance of building façades using standardised parameters that simulate real weather conditions, i.e., a combination of wind-driven rain and driving rain wind pressure. It has been a challenge for researchers to experimentally test simultaneous wind and rain conditions in a rigorous manner. However, two new methods have minimised this problem, creating a precise relationship between the experimental result and the expected performance of the façade under real conditions and vice-versa. This article reviews both alternative methods and analyses their theoretical foundations and comparative advantages. In addition, the two methods are applied in the same case study, analysing the exposure conditions for a generic façade located in Bilbao (Spain). Ten-minute climatic records gathered over 14 years at the city airport have been used for this analysis. The comparative results show an adequate convergence between both procedures. However, their methodological differences would suggest using each one for different specific applications. info:eu-repo/grantAgreement/ES/MINECO-FEDER/BIA2012-31609 info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 3.341 2014 CONSTRUCTION & BUILDING TECHNOLOGY 3 / 59 = 0.051 2014 Q1 T1 ENGINEERING, ENVIRONMENTAL 11 / 47 = 0.234 2014 Q1 T1 ENGINEERING, CIVIL 3 / 125 = 0.024 2014 Q1 T1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Domínguez-Hernández, J.
