HAMSTAD Benchmark 1: Heat and Moisture Transport in an Insulated Roof

Application ID: 75601

This tutorial shows how to simulate coupled heat and moisture transport in an insulated roof structure, made of a load bearing and an insulation layer. The thermal insulation is facing the interior and there is a moisture barrier facing the exterior. The load bearing is capillary active while the insulation layer is capillary non-active, which induces high relative humidity levels at the contact surface between the two materials, resulting in internal condensation. The 1D model is the first benchmark defined in HAMSTAD-WP2 Modeling for the validation of numerical simulations for coupled heat and moisture transport in building materials. See 75741, Heat and Moisture Transport with Mold Growth Prediction for a mold growth prediction study with the VTT model based on the numerical results of temperature and relative humidity of this model.

This model example illustrates applications of this type that would nominally be built using the following products:
