Research on the Optimization of Selecting Traditional Dwellings Patio Renovation Measures in Hot Summer and Cold Winter Zone Based on Thermal Comfort and Energy Consumption

Patio-style dwellings are a highly representative category of traditional dwellings in the Yangtze River Delta region of China. As a crucial climate-adjusting space for traditional dwellings in the hot summer and cold winter zone, patios have long been the focus of practice and research in traditional dwelling renovation. Previous studies have mostly focused on how the shape and scale of patios affect their performance in terms of ventilation, lighting, and thermal environment; however, there is a lack of research on how patio renovation measures influence the thermal comfort of spaces surrounding patios. Based on the two goals of improving the thermal comfort of the general hall space and reducing the overall building energy consumption, this paper takes the patio renovation of Huaigengtang Dwelling as a case study. We use the Design Builder (v7.0.2.006) simulation software to analyze the impact of 10 selected patio measures on thermal comfort and energy consumption and adopt the entropy weight method to conduct a comprehensive evaluation of the indicators for thermal comfort improvement and energy consumption reduction. The quantitative simulation is divided into two scenarios: one where the patio maintains natural ventilation, and the other where the patio is renovated into an enclosed space with split-type air conditioners used for cooling and heating. We select a single patio renovation measure and a combined patio renovation measure based on the values of the comprehensive scores. Regarding the application of the selected optimal measures, and in combination with the dual needs of functional improvement and performance enhancement in traditional dwelling renovation practice, this paper analyzes the corresponding relationships between three types of functional improvement—inheritance-type renovation, optimization-type renovation and replacement-type renovation—and the two performance evaluation indicators, namely thermal comfort improvement and energy consumption reduction, so as to propose the optimal recommendation schemes for different renovation scenarios.
