surface humidity criterion for design purposes by IEA Annex 14

IEA Annex 14: Condensation and Energy

"provided architects, building owners, practitioners as well as researchers, with a better knowledge and understanding of the physical background of these phenomena (critical) conditions for mould growth, material characteristics related to the problems, it has also provided them with better computation models taking air, heat and moisture transfer into account in order to predict properly the phenomena of surface condensation and possible solutions to avoid it."
