Universidad de Zaragoza (orcid)0000-0003-4278-6622 Equivalence between the methods established by ISO 15927-3 to determine wind-driven rain exposure: Reanalysis and improvement proposal 2020 Access copy available to the general public Unrestricted ISO standard 15927-3 establishes two calculation methods to characterise wind-driven rain exposure on building façades, with different approximations according to the available climatic data: (i) a reference method, using hourly wind and rain data, and (ii) an alternative method using average wind records and the present weather code for rain in half-day intervals when hourly data are not available. However, the equivalence between the two methods was only validated in three British cities with similar environmental conditions (London, Manchester, and Edinburgh), and for only four façade orientations. In addition, the description of the second method also admits different interpretations that can influence its results. This study re-examines the real equivalence between the two methods, comparing their results in multiple façade orientations of 12 Spanish locations subjected to varied amounts of wind-driven rain exposure. The analysis shows that the reliability of the method based on non-hourly data varies significantly according to the methodological interpretation applied, making it advisable to review its current description. Finally, an improvement is proposed that reinforces the equivalence and reliability of the alternative method with respect to the reference method, regardless of the climate of the analysed location. info:eu-repo/grantAgreement/ES/MICINN/PGC2018-098459-B-I00 info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 6.456 2020 CONSTRUCTION & BUILDING TECHNOLOGY 6 / 66 = 0.091 2020 Q1 T1 ENGINEERING, ENVIRONMENTAL 12 / 53 = 0.226 2020 Q1 T1 ENGINEERING, CIVIL 6 / 136 = 0.044 2020 Q1 T1 1.736 2020 Building and Construction 2020 Q1 Geography, Planning and Development 2020 Q1 Environmental Engineering 2020 Q1 Civil and Structural Engineering 2020 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Domínguez-Hernández, Javier Universidad de Zaragoza (orcid)0000-0002-3776-9791 Cano-Suñén, Enrique Universidad de Zaragoza (orcid)0000-0001-5137-2478 Alonso-Martínez, Mar del Coz-Díaz, Juan J. 5004 510 Universidad de Zaragoza Dpto.
