EMPD-based moisture buffering quantification with moisture-dependent properties (?): Modelling and simulations

Materials with excellent moisture buffering performances have considerable application potential in the future developments of building design. The appropriate materials is determined via effective assessment their hygroscopic performance, however, currently available test methods (e.g., buffer value test) can evaluate only abilities under limited circumstances. Advanced numerical prediction heat, air and transfer (HAM) models) are not practical because unavailable hygrothermal properties excessive computation times. Integrating penetration depth (EMPD) model an inverse approach allows both identifying predicting effect on room conditions effectively efficiently. This paper reports that existing EMPD models conditions, hence proposes a modified two-layer considering moisture-dependent hygric reasonable resistance distributions. A novel dynamic presented terms typical fluctuations office buildings. Compared to standard property tests, combination extract key parameters efficiently effectively. Thus, actual performance be accurately predicted for wider spectrum conditions. precision proposed validated by comparing predictions measured results HAM results. method, advantages simple procedure, low experimental cost, high efficiency, wide applicable range, advisable applications. • consider properties. identify material ability. extracted solution.
