Repeated wetting, drying, freezing and thawing of the fabric of a building can cause problems such as damp, condensation, mould growth and loss of thermal performance, and may even result in premature failure.
Computer-based hygrothermal modelling simulates the movement of heat and moisture, generating information relating to temperature, water content and relative humidity within multi-layer building elements.
- Water leaks.
- Wicking of groundwater.
- Penetrating and rising damp.
- Air infiltration and condensation through the building fabric.
- Vapour diffusion.
By simulating the performance of building assemblies, the risks of problems associated with these mechanisms can be evaluated and minimised. By understanding risks such as condensation, moisture entrapment, fungal growth, material degradation, and so on, the correct balance between heat and moisture can be achieved.
