Abstract

Purpose – Rising damp affects the deterioration and conservation of architectural heritage. Air cavities built next to the base of these buildings on an unsaturated floor can reduce the damage to foundations and walls due to this. These are passive systems, which are usually designed with no objective data to show their functioning and effectiveness. This is why the authors are presenting this study. Design/methodology/approach – This study is presented starting with simple field equipment for representative types for a previous cataloguing of cases in Spain. The physical parameters of the air in this research are air speed and evaporation in the cavities and the base, taking the local climate and the particular formal and construction characteristics of each case study as a reference. Findings – The results of the analysis validate the method and the efficiency of such cavities, whose performance is greater in systems with a variety of features, that is to say, those which work by thermal or wind flow rather than those which only use hygric flow. Originality/value – This work is novel because there are not in situ experimental works which prove the functioning and effectiveness of these systems.<br />Depto. de Pintura y Conservación-Restauración<br />Fac. de Bellas Artes<br />TRUE<br />pub
