Conclusion and outlook

During those two months, we studied another benchmark for the heat and moisture transport process in a porous wall. We also added some improvement to the application be began to develop during the master’s project, using technical features of Feel++.

Then, we studied a more complex case, adding to the model the transport of heat and moisture in a room air, in order to simulate in the furute on whole buildings. Unfortunately, the resulting application is not yet fully operational. The current simulation results don’t macth the hypothesis. The work will be continued at Cemosis to identify and fix the bug.

We also worked on the HDG method to propose an alternative strategy for the resolution of the coupled PDE and ODE problem of rooms and whole buildings. In addition, we studied the Fanger model for thermal comfort assessment. Unfortunately, the short duration of the internship didn’t allow us to implement these two features. Future works are planned at Cemosis to carry on this project.

Finally, we can link this work with what is done by my colleagues: Romain studied raditive heat transfer, and Hanane and Sarra worked on the missing data (and particularly comfort criteria). Indeed, radiative heat transfer and thermal comfort models can be integrated in the hygrothermal model for a better evaluation of the temperature and relative humidity. This will also improve the assessment of the thermal comfort and help in the management of the energy systems in order to improve the occupants comfort and optimize the building energy consumption.
