Risks of mould growth in different building structures

Abstract

Abstract. In the current paper the impact of real Latvian climate conditions on a variety of building constructions is inspected. The influence of the humidity on buildings' sustainability in three different building units has been appraised. Condensate risks in a multi-layer wall are analyzed by transient outdoor climatic conditions. Risks of mould growth are discussed in detail taking into account the properties of building materials, dependence of humidity on temperature and season. The effect of vapour barrier is analyzed from several aspects. Theoretical analysis has been done based on real test stands built in Riga. Some experimental results are obtained.
