This article focuses on the behavior of an accommodation with Trombe walls in a Mediterranean climate; in terms of energy savings and comfort during wintertime and summertime.

The aims of this study are to identify experimentally temperatures and heat fluxes of the solar wall; compare the solar wall’s behavior with a traditional wall from the point of view of consumptions and comfort; optimize the wall in relation to energy savings. In order to do that; various activities were carried out: a series of monitoring activities for several years in different seasons (in this paper only the results obtained for winter and autumn are reported); dynamic simulations with software EnergyPlus on a virtual model calibrated by comparison with experimental results; parametric analyses for the optimization of the wall.

The results demonstrated that solar wall is an efficient system in temperate climates; with an energy savings of 12;2% and summer comfort comparable to that provided by traditional housing. Finally it was possible to identify optimal design features (Thickness of the wall; absorbance; type of glass).
