- Abstract
The exterior wall, essential to the envelope structure of Huizhou residential buildings, enjoys a unique ability to adapt to the local environment and climate. However, there is a lack of experiments and quantitative data on the thermal performance of exterior wall materials, owing to the complexity in the current situation of Huizhou residential buildings. Therefore, the purpose of this study is to explore the physical properties and energy transfer features of the exterior walls of Huizhou residential buildings. Specifically, the thermal performances of four types of walls of Huizhou residential buildings, with different materials and structures, were compared through field survey, field test and lab test. The principal conclusion is that the heat transfer coefficients of the four types of walls, namely, the traditional rowlock cavity wall made from black bricks and yellow mud, the new rowlock cavity wall with cement bricks, the new composite wall of Hongcun Village, and the solid wall of self-built houses in Jicun Village, were respectively, 1.892 W/m2·K, 2.821 W/m2·K, 2.024 W/m2·K and 3.588 W/m2·K; the traditional rowlock cavity wall made from black bricks and yellow mud boasted the best thermal performance. The research findings lay the basis for the development of ecofriendly walls that adapt to the local climatic environment.
