A parametric study of the energy and moisture performance in Passive House exterior walls

Adding insulation to improve the energy performance of a building with a traditional Swedish wooden construction may increase the risk of mould growth in the wooden construction. There is a need to address this potential problem since the amount of passive houses and low energy buildings are increasing as a means to reduce energy use, energy dependency and greenhouse gas emissions.

Characterization of progressive damage in concrete using impact non-linear reverberation spectroscopy

Nonlinear acoustic methods have shown potential for the identification of early damage in brittle materials such as concrete. Commonly, these methods evaluate relative nonlinearity parameters from multiple resonance tests at different amplitudes. We demonstrate a recently developed alternative method, Impact Nonlinear Reverberation Spectroscopy (INRS), where quantitative nonlinearity parameters ar
