WUFI is a specialist building physics software used to assess the movement of heat and moisture through building assemblies over time. WUFI analysis, also known as hygrothermal analysis, helps identify potential moisture, condensation and durability risks within walls, roofs and other building envelope assemblies.
Performance Building Consultants provides WUFI analysis for architects, designers and builders throughout New Zealand, helping assess and optimise building envelope designs.
Understanding moisture performance
Moisture can enter building assemblies through vapour diffusion, air leakage and rain penetration. Depending on the materials, climate and construction, moisture can accumulate and increase the risk of condensation, mould or material deterioration.
WUFI modelling allows these processes to be assessed dynamically under realistic climate conditions, providing a better understanding of how an assembly is likely to perform over time.
WUFI analysis can assess:
- Moisture content and accumulation
- Interstitial condensation risk
- Drying potential
- Temperature and relative humidity within assemblies
- Vapour control strategies
- Alternative wall and roof constructions
- The performance of insulation and building materials
Hygrothermal analysis is particularly useful for high-performance buildings, highly insulated or airtight assemblies, timber construction, renovations and unusual or innovative building systems where moisture performance may be uncertain.
WUFI analysis for your project
WUFI analysis can provide evidence to support decisions around insulation, membranes, vapour control layers and other building envelope components, helping designers develop assemblies that are both thermally efficient and moisture resilient.
Whether you're assessing a new construction system, modifying an existing assembly or investigating a potential moisture risk, WUFI analysis can provide valuable insight into how the building envelope is likely to perform.
