dc.description.abstract In the last years, people has become aware of energy saving and thermal comfort requirements for home buildings in hot and cold seasons. In the present study, hybrid multifunctional constructive components made of a reinforced mortar channel filled with cement-soil-sawdust (CL2MSCAL) were evaluated to experimentally determine their thermal performance (thermal conductivity, thermal time lag and decrement factor). The experimental analysis performed in this study was based on dynamic climatology. Measurements of components surface temperature were conducted to determine temperatura damping and temperature wave lag. Monthly average temperature and direct solar radiation data of the site was considered. Measurements of real-scale constructive components were conducted on a fully equipped thermal conductive system and thermal chambers (test cells) built for this purpose. Results are compared to concrete components (CCL) that account for approximately 71.6% of the houses built in Mexico and 43.2% in Oaxaca and reinforced mortar (CML) used as prefabricated housing systems. Best results were found for component CL2MSCAL that has a thermal conductivity of 0.81 W?m-1?K-1, a thermal damping of 81.5% (decrement factor of 0.166) and time lag of 7:37 h compared to CCL that present a time lag of 1 h and decrement factor of 0.9. Thus, it is concluded that CL2MSCAL roofing channel components are an alternative for energy saving and thermal comfort. es_MX
