摘要

In campus buildings in China’s hot–humid regions, external corridors are vital for students' extracurricular activities. However, high temperatures and humidity in summer often worsen thermal conditions, affecting comfort. This study combines field measurements and surveys to evaluate the thermal environment and comfort of corridors facing four directions and uses the Ladybug Tools for simulation with 80 scenario combinations to optimize the design. The results showed: (1) Air temperature significantly affects thermal sensation for all corridors, with the mean radiant temperature having no significant impact on the north-facing corridor and solar radiation affecting the east and west corridors; (2) The neutral physiological equivalent temperature (PET) values for the east-, west-, south-, and north-facing corridors are 28.8 °C, 30.8 °C, 26.2 °C, and 32.3 °C, respectively. The acceptable PET values are 31.3 °C, 33.4 °C, 30.5 °C, and 35.8 °C, respectively. (3) For the north-facing corridor, the average PET at 4.2 m is 0.2 °C lower than at 1.8 m, with combined shading providing the best cooling. For the south-facing corridor, combined shading reduces the average PET by 5.4 °C at 1.8 m, with optimal cooling at depths of 1.8 m and 2.4 m. Horizontal shading outperforms vertical shading at depths ≥ 3.0 m, but combined shading remains the most effective. (4) In the west-facing corridor, combined shading lowers the average PET by 1.5 °C at 1.8 m, and by 1.6 °C in the east-facing corridor. Combined shading consistently provides the best cooling. This study provides scientific guidance for the design of campus building corridors.
