Although implicit methods require extra calculation, they have been largely used for obtaining numerical approximations of time-dependent differential conservation equations in the building science domain, thanks to their stability conditions that enable the use of larger time steps. Nevertheless, they require important sub-iterations when dealing with highly nonlinear problems such as the comb...

The construction industry is currently one of the least digitised. However, due to recent technological developments, building information modelling and management (BIM) systems are increasingly being used increase efficiency constructions sustainable use resources energy buildings. In case new or renovations, properly designed hygrothermal behaviour materials, elements structures unavoidable a...

Unwanted sound reflection can create acoustic discomfort and lead to problems of speech comprehensibility. Contemporary building techniques enable highly finished internal walls resulting in sound reflective surfaces. In contrast, sustainable construction materials using natural and vegetal materials, are often more porous and absorptive. Hemp shiv is used as an aggregate and when mixed with li...

Three biopolymers were tested as rammed earth (RE) stabilizers, evaluating their impact on the hygrothermal behavior from material to building scale. Hygrothermal characterization included determination of sorption isotherm, water vapor permeability, thermal conductivity at different moisture content, and specific heat capacity. The data used input for simulation whole-building scale considerin...

A multi-scale modelling strategy is proposed to investigate the potential effects of hygrothermal ageing on ballistic performance CFRP laminates. At micro-scale, damage evolution due cyclic loads simulated a representative microstructure using an adapted fatigue law. Then, results micro-mechanical analysis are used measure predicted transverse crack density and calibrate meso-scale material mod...
