Indoor　mould　growing　on　the　wall　surface　can　not　only　degrade　building　materials,　but　also　endanger　occupants’　health.　It　is　of　great　significance　to　study　the　mould　growth,　especially　for　domestic　research.　This　paper　takes　the　thermal　bridge　of　building　as　an　example,　which　is　located　in　Shanghai.　Then　the　hourly　temperature　and　relative　humidity　were　obtained.　And　the　VTT　model,　MRD　model　and　WUFI-BIO　model　are　used　to　calculate　for　assessing　the　mould　growth　in　one　year.　From　the　result,　the　mould　growth　in　Shanghai　is　mainly　concentrated　in　summer.　The　three　models　evaluate　mould　growth　in　different　ways.　And　the　VTT　and　MRD　model　show　that　the　mould　growth　time　is　longer　than　MRD　model　in　Shanghai.　The　description　of　VTT　model　is　relatively　straightforward　in　the　result　display.　Besides,　according　to　the　prediction　principle,　the　MRD　model　covers　the　wider　influencing　factors　of　mould　growth.　©　2020,　Springer　Nature　Singapore　Pte　Ltd.
