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...

The use of bio-based insulation materials is widely spreading in buildings. Due to their organic load, they can be an important source Volatile Organic Compounds (VOCs). This study among the first that evaluates spatial and seasonal in-field VOC surface emissions from conventional building structures as a whole, French public insulated with wood wool. In addition emissions, measurements concent...

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...

The objective of this work is to quantify the effects short-term climate change with a multiyear (MY) approach on results heat and moisture transfer simulations an historic building located in Udine (Italy) evaluate if single year simulation could be representative obtained MY. hygrothermal performance related risk are evaluated for brick wall without insulation, MY 25 years three selected form...

The effect of hygrothermal conditions (air temperature and relative humidity) on the dehydration of theophylline monohydrate was investigated. Firstly, the equilibrium states of theophylline were investigated. The data from gravimetric analysis at constant temperature and humidity were reported as desorption isotherms. The PXRD analysis was used to identify the different polymorphic forms of th...

The majority of contemporary insulation materials commonly used in the building industry is made from non-renewable raw materials; furthermore, their production often brings high energy costs. A long-term trend as far as sustainable development is concerned has been the reduction of energy and material demands of building material production. One of the solutions is the possibility of using eas...
