ABSTRACT: The
purpose of this study is to experimentally analyze the thermal behavior of the
walls of a prototype experimental house. A Datalogger and thermocouples were
used on the experimental house to determine the temperatures of the exterior
and interior walls. Also, “MSR” type HygroPuce was used
to determine the exterior and interior temperatures and relative humidity of
the habitat. The results show that a wall made of bio-based materials with a
mixture of “earth + Hibiscus cannabinus L. fibers” allows reducing the fluctuations of the interior temperatures. We observe the peaks of
temperatures on the external walls at 11:00 am and
for the interior walls, the peaks are observed at 5:00 pm. The
maximum thermal phase shift between the peaks of the external and internal
temperatures is about 7.5 hours, and the maximum damping factor is 0.9. Also,
we note that the thermal performance of the material used in the design of the
envelope of the house is determined by the improvement of the response of the envelope in front of the external
thermal solicitations.
