Appreciation of the delay in the benefits of the thermal energy released by PCM in civil engineering structures

To optimize de-icers use in winter on roads and airports, some sustainable solutions were promoted in a global project entitled "Roads of the Future". PCM into pavements were then considered to rely on the released enthalpy to delay the occurrence of black ice or snow accumulation. Coupling a spectroscopic monitoring of the PCM behavior and thermography on pavement surface indicated a significant delay between the phase change and the thermal manifestation of the released energy. Considering an accurate description of PCM according to cooling weather phenomena, these elements might provide valuable information for numerical models.

Benchmark de méthodes d’identification de paramètres sur données simulées : application à la mesure sur site de la résistance thermique de parois de bâtiments en utilisant la thermographie infrarouge active

Résumé – Ce travail porte sur la réalisation d’un benchmark de méthodes d’identification en vue de mesurer sur site la résistance thermique de parois de bâtiment par thermographie infrarouge active. Les mesures virtuelles sont générées à l’aide de différents Modèles Physiques Générateurs. Plusieurs méthodes d’estimation de paramètres sont comparées. Les résultats présentés se focalisent sur les parois ITI (Isolation Thermique par l’Intérieur) et montrent qu’une estimation satisfaisante de la résistance thermique de la paroi est possible dans de nombreux cas.
