Human comfort and healthy environments lie at the core of every debate about outdoor spaces nowadays. Thermal comfort is a vital concern for planners and designers in order to produce a healthy and thermally comfortable environment, since the influence of different climates and user groups has been found to greatly alter the range of responses for thermal comfort calculations. This requires Post-Occupancy Evaluation (POE) with an integration of the appropriate outdoor thermal comfort (OTC) index. This paper presents the results of a detailed assessment for the OTC in hot arid zone (HAZ) using the most suitable thermal index. A case study was selected from Effat Campus, Jeddah, Saudi Arabia, to represent the HAZ. Subjective assessment employed the physiological equivalent temperature (PET) and the predictive mean vote (PMV) thermal indices in analysing the results of online and self-directed questionnaires while objective assessment employed a hand-held anemometer that was used to measure wind speed, whereas the wet bulb globe temperature (WBGT) SD Card Logger with a black globe thermometer 75 mm in diameter and emissivity of 0.95 was used to measure the globe temperature. The physical measurements were later used to calculate the mean radiant temperature (MRT) and consequently the PET index using RayMan Software. The results confirmed the significance of the shading strategy on OTC. The study revealed that there is no percentage as shading is permitting people to use the space; otherwise, in hot arid zone, the space would be completely unusable under the sun while the PET is more suitable than the PMV index.

干旱地区热舒适度的居住后评估

在当今有关室外空间的所有辩论中，人的舒适性和健康的环境是每项辩论的核心。为了创造一个健康，热舒适的环境，热舒适性对于规划人员和设计师而言至关重要，因为已经发现不同气候和用户群体的影响会极大地改变热舒适性计算的响应范围。这就需要对占用后评估（POE）进行整合，并整合适当的室外热舒适度（OTC）指数。本文介绍了使用最适合的热指数对热干旱地区（HAZ）的OTC进行详细评估的结果。从沙特阿拉伯吉达的埃菲特校区选出一个案例研究来代表热影响区。主观评估使用生理等效温度（PET）和预测平均投票（PMV）热指数来分析在线问卷和自我指导问卷的结果，而客观评估则采用手持风速计来测量风速，而湿球温度（WBGT）SD卡记录仪和直径为75毫米的黑色地球温度计，发射率为0.95，用于测量地球温度。随后使用物理测量来计算平均辐射温度（MRT），并因此使用RayMan软件计算PET指数。结果证实了遮光策略对OTC的重要性。研究表明，由于阴影允许人们使用该空间，因此没有百分比。否则，在炎热的干旱地区，
