Multidimensional HAM conditions

Measurements on full-scale wall elements in the large climate simulator at SBi Moisture and temperature levels and variations in time and space play a crucial role in the degradation processes of building materials. In order get a better prediction of the interaction between the indoor environment and the building component used in computational models for multidimensional Heat, Air and Moisture (HAM) conditions, experimental data are needed. Tests were performed in the large climate simulator at SBi involving full-scale wall elements. The elements were exposed for steady-state conditions, and temperature cycles simulating April and September climate in Denmark. The effect on the moisture and temperature conditions of the addition of a vapour barrier and an outer cladding on timber frame walls was studied. The report contains comprehensive appendices documenting the full-scale tests. The tests were performed as a part of the project 'Model for Multidimensional Heat, Air and Moisture Conditions in Building Envelope Components' carried out as a co-project between DTU Byg and SBi.
