However, urban climate models usually neglect moisture transfer through walls. This work proposes a new numerical method for solving coupled mass and heat transfer, especially adapted to urban scale simulation. This method has been numerically validated by comparison with a reference tool DELPHIN, on several study cases. Moreover, its reliability for representing old walls is verified by comparing the results of the simulations with data measured in historic buildings in Cahors (France). The integration of a coupled transfer model solved with this resolution method into an urban climate model allow the simulation of the hygrothermal behaviour of old walls and the evaluation of their energy and microclimatic impact at the urban scale.","PeriodicalId":406541,"journal":{"name":"Evaluation of a new numerical method for solving hygrothermal transfer through walls in the context of a historical city centre","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126766684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
