This study aims to evaluate the hygrothermal performance of a wall constructed with rapeseed concrete under actual weather conditions. To this end, a case study is conducted using the WUFI software, with various coatings and according to the climate conditions on Ile de France. The results of the thermohygric characterization of non-load-bearing insulating bio-based concrete blocks were used as input data for simulations conducted using the WUFI tool. The results show that the wall has good hygrothermal behavior when an external mineral coating with an Sd value of 25 is added. The recommended thickness for good thermal insulation and temperature phase shift is 30 cm.","PeriodicalId":406125,"journal":{"name":"A numerical case study of a wall composed of pre-cast rapeseed concrete blocks","volume":"481 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":"124413441","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}
