Overcoming condensation problems in a closed cavity double skin façade
For highrise office buildings, double skin façades offer a attractive alternative in building envelope conception. A recurrent problem in concepts with single outdoor and double indoor glazing (“passive façade”) is condensation on the cavity side of the single glass pane. Permasteelisa Group developed a innovative concept, employing a fully sealed cavity and a very modest dry air flow (“closed cavity façade”), that prevents condensation at all times, thus preventing dirt offset on the window panes and eliminating the need for cleaning inside the cavity over the lifetime of the façade. This paper presents a coupled multizone airflow / thermal model developed to assess condensation risk inside the cavity under different climate conditions and the initial validation. Additional validation experiments are held in the 2008-2009 winter season. This model is now implemented as a R&D tool and to size the system components in actual projects.
