Paradigms for building physics analysis with a focus on moisture modelling – description of how the theme has evolved

le 7 avril 2016

Carsten Rode, Professeur au Dept. of Civil Engineering, Technical University of Denmark interviendra lors du séminaire du LMT à l'ENS Cachan.

Computational modelling of moisture transfer and moisture conditions in building components and whole buildings has gone through quite some development during the years since such simulations became possible for practitioners some 25 years ago. The lecture will give an overview of how the possibilities have evolved over those years - and give some indication of what will come in the future. The evolution goes in these steps:
-    Steady state, diffusion-only calculations of moisture with the Glaser method,
-    Transient 1D calculations with MATCH, which also covers liquid moisture transport, detailed consideration of boundary conditions and sorption/suction curves with hysteresis. Later on also WUFI, DELPHIN and other programs do this.
-    Mulitidimensional simulations, e.g. with WUFI 2D
-    Whole building simulation of transient heat and moisture conditions, e.g. with BSim and later on with WUFI Plus.
-    Recent evolutions also cover interactions with other aspects of indoor atmospheric conditions, not least ventilation regimes such as with CHAMPS (Combined Heat, Air, Moisture and Pollutant Simulations).
-    Simulation packages such as COMSOL and Modelica give new possibilities.
Several IEA projects have been central governing this evolution. The future will bring more integrations between phenomena, e.g. even on the city scale, and it will involve stochastics in the simulations.
Beyond the application-oriented possibilities with computer codes, the lecture will also give a presentation of some fundamental paradigms, which are believed to be further developed in the future and then become integrated in practical models.
