Thermal Performance Analysis and Improvement Measures of Square Tulou Buildings, take the Instance of Zhenyang Tulou in Nanjiang Village, Yongding China

Abstract

Tulou is mainly distributed in western Fujian and northern Guangdong, mostly in Yongding and Nanjing County. Previous studies focus more on the monomer space type of tulou. But the study of earth's physical properties is still insufficient. This paper has done a series of studies on thermal environment of tulou in Nanjiang Village, Yongding County, Fujian. Take the representative square Zhenyang tulou for instance, measurement has been done on its temperature and humidity and other environmental parameters, and an objective evaluation of physical environment in tulou has been given based on the comparison of the performance of tulou and local modern brick houses. On this basis, analyses have been done on the defects of thermal environment of tulou, and further generate the improvement measures proposal of building envelope, especially the wooden wall and wooden floor. Based on the before-and-after performance, the study will provide useful reference for the reuse and development of tulou under the premise of protecting its architectural form and spatial integrity.
