Abstract

Keywords

To identify the optimal spatial form of tropical traditional courtyards in hot-humid regions， thermal comfortwas employed as the key indicator for microclimate evaluation.Two typical courtyard types from Sanqing Village，a nationally recognized traditional ancient village in Haikou City，were selected for analysis. Using field surveys and ENVl-met numerical simulations，this study examined the relationship among courtyard depth，microclimate parameters，and thermal comfort to identify highly comfortable courtyard configurations. Results show that increasing courtyard depth significantly improves thermal comfort by lowering air temperature，increasing relative humidity，and enhancing wind speed，while decreasing depth produces opposite trends.Optimal thermal comfort was achieved at a courtyard depth of 8 meters，with linear courtyards outperforming L-shaped ones.Based on these findings，design strategies are recommended to optimize courtyard microclimates， including strategic vegetation placement and the use of perforated landscape walls to enhance ventilationand thermal performance.
