Abstract text:
In the current context – where climate change has become not only a certitude but also, according to several studies, even irreversible – the mitigation of the negative impact of human niche on the environment has become an absolute value in the underlying systems of value within human society. The accelerating rhythm of climate transformations suggests that the global scientific society has been taken by surprise. In the field of civil constructions, responsible for a significant amount of gas with greenhouse effects – caused by both the energy input for their exploitation and the energy embodied in their execution – substantial efforts have been made lately in order to implement the principles of sustainable development. To this end, complex material and compositions were designed, to obtain higher energetic efficiency levels. Whereas the building materials are assessed before the execution, their behaviour in situ has not been analysed most of the times. Furthermore, the analysis methods are limited and they involve long-term monitoring processes. The paper proposes a synthesis of the analysis methods of the hygrothermal behaviour of the systems of envelope in-situ.
