Multi-scale approach of Hygrothermal and Pollutant Behavior of Bio-based Building Materials – HygroPo-BBM

Submission summary

Indoor air quality (IAQ) and hygrothermal comfort are health issues and are two of the important elements taken into account in the French regulation-RE 2020. The project HygroPo-BBM proposes a multi-scale approach (micro-macro) to model the hygrothermal and pollutant behavior of bio-based building materials (BBM) that are renewable and perfectly meet the challenges of sustainable development. The microstructure, the hygrothermal properties and the uptake of Volatile Organic Compounds (VOC), the “hygric and VOC” buffering capacity of BBM will be measured, analyzed and modeled. The similarity between the sorption and diffusion of water vapor and VOCs will be studied and investigated in order to build a database of VOCs from the hygric properties available in the literature. The results obtained are very useful to develop new formulation for BBM and to optimize the sustainable buildings design that takes into account both objectives of indoor environment and energy consumption.
