The characterisation of these exposures for each possible façade orientation of a building requires analysing exhaustive wind direction records, which significantly increases the calculation effort and prevents calculation in locations without such records. This study examines the possibility to avoid this directional analysis, equally obtaining a functional and reliable exposure characterisation. For this purpose, daily climatic datasets were analysed from 920 weather stations subjected to various environmental and topographic conditions in Mexico, Norway and Spain, and the directional and scalar exposures to wind-driven rain and driving-rain wind pressure were determined at each location. The results show that the maximum directional exposure can be adequately approximated using the scalar exposure value, without the use of wind direction records. Considering the usual constructive practice of using a single façade design for the entire building, this simple and functional characterisation of the expected exposure on the most unfavourable orientation provides a significant support for the design decisions of practitioners. 000150010 536__ $$9info:eu-repo/grantAgreement/ES/MICINN/PGC2018-098459-B-I00 000150010 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttps://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 000150010 590__ $$a6.456$$b2020 000150010 591__ $$aCONSTRUCTION & BUILDING TECHNOLOGY$$b6 / 66 = 0.091$$c2020$$dQ1$$eT1 000150010 591__ $$aENGINEERING, ENVIRONMENTAL$$b12 / 53 = 0.226$$c2020$$dQ1$$eT1 000150010 591__ $$aENGINEERING, CIVIL$$b6 / 136 = 0.044$$c2020$$dQ1$$eT1 000150010 592__ $$a1.736$$b2020 000150010 593__ $$aBuilding and Construction$$c2020$$dQ1 000150010 593__ $$aGeography, Planning and Development$$c2020$$dQ1 000150010 593__ $$aEnvironmental Engineering$$c2020$$dQ1 000150010 593__ $$aCivil and Structural Engineering$$c2020$$dQ1 000150010 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000150010 700__ $$0(orcid)0000-0002-3776-9791$$aDomínguez-Hernández, Javier$$uUniversidad de Zaragoza 000150010 700__ $$0(orcid)0000-0001-5137-2478$$aCano-Suñén, Enrique$$uUniversidad de Zaragoza 000150010 700__ $$aMartínez-Martínez, Juan E. 000150010 700__ $$adel Coz-Díaz, Juan J. 000150010 7102_ $$15004$$2510$$aUniversidad de Zaragoza$$bDpto.
