Abstract

This article aims to analyze the thermoenergetic impacts generated by the use of cold roofs in low-income single-family buildings in Recife/PE, Brazil. Computational models encompass scenarios involving the use of cold roofs (solar absorptance of 0.25), degraded cold roofs (solar absorptance of 0.42) and standard roofs (solar absorptance of 0.65), and consider variations in occupancy profile, user behavior, and roof system insulation. The results indicated that cold roofs with low insulation exhibit more efficient indicators regarding thermoenergetic behavior, impacting the improvement of thermal performance of the housing unit, as well as reductions in the flow of heat released by long-wave radiation and energy consumption. It is concluded that cold roofs are effective alternatives for single-family buildings situated in the climatic context of Recife/PE, Brazil.
