A Review on the Practical Value of Passive Roofs for Rural Housing in Panzhihua, China

Abstract

The climate of Panzhihua, China, is characterized by dry, hot, and strong solar radiation. However, the existing regulations classify the region as a moderate climate zone at first, ignoring the local climate characteristics, resulting in a lack of effective guidance for housing construction. Due to the growing needs of residents, roofs in the area have adopted many immature climate response strategies. The research objective of this study is to conduct a literature review of existing roofing strategies, identifying and prioritizing the roles and importance of passive roofing in the region. The thermal performance of common passive roofs in this region, including GRs, CRs, VRs, and BRs, is analyzed, and the practical value of these passive roofs in the hot-dry region is demonstrated. This study will effectively guide the construction of residential roofs in the region, which is conducive to building energy conservation and resource utilization in the region.
