Title of the ANR RESBIOBAT project: In-situ measurement of the thermal RESistance of highly insulated and BIO-based building walls

Description: In a context of energy and environmental renovation, major advances are expected in the building sector. A better in-situ thermal assessmentof buildings before and after renovation is necessary. In addition, construction must become more sustainable, notably by using bio-based materials and raw earth. In this project, we propose an interdisciplinary technical solution combining modeling, simulations, and measurements for a better in-situ characterization of the energy performance of conventional and sustainable walls. The identification of thermal characteristics will be carried out using an inverse method integrating a hygrothermal model solved in real time by a "reduced basis" approach and sensors selected by "optimal experimental design". After a robustness study via virtual tests, a prototype will be produced and tested on real walls in the laboratory and in the Sense-City Excellence Facility.
