Hygrothermal (Condensation Risk) Analysis
In June 2010, John Morehead qualified as a WUFI user in Cardiff University and is one of only a few individuals in Ireland in a position to carry out a hygrothermal (condensation risk) analysis of multi-layer projects to BS EN 15026, Hygrothermal performance of building components and building elements. Assessment of moisture transfer by numerical simulation.
A WUFI analysis is calculated to predict moisture transfer in multi layer components of a building fabric such as an external wall or roof construction etc. This is a valuable tool during the design stage of a project to reduce condensation risk. It can also be used on existing buildings to assess if and why mould growth or condensation risk is likely to occur and how the likelihood of this happening can be mitigated.
While WUFI can asses whether interstitial condensation will occur, Thermal Modelling can determine whether there is a risk of surface condensation at a junction, frsi factor or temperature factor. Thermal modelling can be used to assess surface condensation risk at 2D junctions, but can also be used to assess complex 3D junctions where there may be penetrations in the external envelope.
