Development of HAM tool for building envelope analysis

In-cavity evaporation allowance—A drying capacity indicator for wood-frame wall system

“…The test setup, in particular details about the installation, collection and data processing of the 757 gravimetric samples, is described in [42], which defines the envelope drying capacity as the ratio between the measured vapor evacuation through the sheathing and the measured vapor evaporation from the water tray. The experimental data were also used to validate a HAM simulation model to complement the experimental results, such as provide a smooth, multi-colored surface contour plot of the temperatures and RH across the 2D wall sections [43]. This paper focuses on the drying capacity of the building envelope from a limit state approach and on the details of the water tray testing system.…”

Experimental data set for validation of heat, air and moisture transport models of building envelopes

“…Moreover the ease to incorporate a thick insulation layer between the wooden studs makes light weight buildings relatively simple to build, sustainable and renewable. But while high thermal performances are easily achievable, such constructions are susceptible for moisture-related structural deteriorations [1]. Moreover excess moisture can lead to the growth of pathogenic moulds and reduce the esthetical appearance of buildings [2].…”

Dynamic coupling between vapour and heat transfer in wall assemblies: Analysis of measurements achieved under real climate

“…Some were first dedicated to the estimation of the energy consumption at the whole building scale e the so-called BES (Building Energy Simulations) models e [45]; ESP-r [3,9]; etc. ), while others were specifically designed to study coupled transfer at the envelope or at the whole building scale e the so-called HAM-model, (WUFI and WUFI-Plus [1,14,19], HAM-Tools [16], HAM-BE [25], HAM Fit Plus [44], etc.). A classification that highlights the models' specificities was proposed in Ref.…”
