Ecological building design based on the optimization of thermal performance of stilt houses in Guangxi Province

Abstract

Traditional stilt houses in Guangxi Province are ventilated and breathable in summer with good dehumidification and heat insulation performance. In winter, however, their airtightness and thermal insulation abilities are relatively poor. In order to analyze the advantages and disadvantages of the thermal performance of stilt houses in Guangxi Province, this study designs four ecological buildings: Building A is a traditional stilt house with a sloping roof and wooden fences; Building B is a reinforced concrete structured house with a flat roof; Building C is a reinforced concrete structured house with a sloping roof and surrounding self-insulating blocks; Building D has the same conditions as C, except its louvers. Through the Swire energy consumption simulation, we can obtain an ideal multi-layer ecological civil building with a thermal-insulation top layer that can be opened as well as louvers and self-insulating blocks used for the outer wall.
