A model for assessment of heat and moisture transfer through hollow porous buildings elements

Abstract Moisture is one of the leading causes responsible for the worst of health conditions and energy performance in households and workplaces. To avoid it, the coupling between a combined heat, air and moisture (HAM) model and a CFD code becomes a crucial research topic to provide accurate results for real problems found in the building sector. Therefore, this paper presents a CFD-HAM model performed in one- and two-dimension simulations, displaying different results for each case. A comparison between one- and two-dimension heat and mass transfer migration through plaster and brick - with trapped air - is carried out, showing the potential of the proposed advanced modeling to solve complex heat and moisture transfer through building elements.
