❓ Frequently Asked Questions
What is hygrothermal modeling?
A simulation of heat and moisture transport in building materials over time, predicting temperatures, moisture content, and humidity to assess performance and risks like condensation.
What is WUFI and what is it used for?
WUFI is a hygrothermal simulation tool that models coupled heat and moisture transport in building components using climate data, helping assess condensation risk, moisture loads, and energy performance.
What inputs are needed to run a hygrothermal model (e.g., WUFI)?
Climate data (hourly temperature, humidity, radiation), material properties (thermal conductivity, density, moisture diffusivity, sorption isotherms), layer stack geometry, boundary and initial moisture conditions.
What outputs does the software provide and how should they be interpreted?
Outputs include time-varying temperatures, relative humidity, moisture content across layers, and condensation risk indicators; use them to identify high-risk areas and guide design or material choices.
