The thermal performance of three roofing models: tile, corrugated and
earth terrace is numerically analyzed. The mathematical equations which govern
the three roofing models are established by the electrical method of analogies.
These equations are discretized by an implicit finite difference method and
solved by the Gauss-Seidel algorithm. We analyze the influences of geometric
parameters (Xlo, Xlarg, α and Ep) on
the evolution of the temperatures of the different
environments of our three roof models. In particular, we have shown that
the effectiveness of a roof in reducing the temperature inside a room is linked
to its physical properties. The results obtained that for the same geometric
parameters, the earth roof terrace and the earth tile roof compared to the
corrugated metal roof improve thermal comfort by lowering the interior
temperature of 5ºC and 4.6ºC.
