Outdoor thermal comfort (OTC) has a significant effect on the health and well-being of urban dwellers. One of the key factors contributing to the tempo-spatial variation of thermal comfort in urban neighbourhoods is the geometrical characteristics. This paper develops a novel modelling framework to comprehensively evaluate the tempo-spatial thermal comfort performance of neighbourhoods on the basis of geometrical features. A weighted temporal thermal comfort performance (TCP_w) metric is furthermore proposed to translate the thermal comfort results to a comparative performance criterion. Universal thermal climate index (UTCI) is the index chosen as baseline for assessing this metric. To demonstrate the practicality of the developed framework, three urban areas with different morphological character in climate zone of Tehran are investigated. Different geometrical variables of these locations are initially extracted from existing datasets using geographic information systems (GIS). A high-resolution spatial model is then developed to simulate thermal comfort of the neighbourhoods by coupling an energy simulation model (EnergyPlus) and a thermal comfort plugin (Ladybug). The model is successfully validated against a series of in-situ measurement data. Results indicate that differences in comfort performance are related to the simultaneous effects of neighbourhoods' layout (density, open areas), and street canyons' profiles (aspect ratio, orientation).

户外热舒适度（OTC）对城市居民的健康和福祉具有重要影响。几何特征是造成城市邻里热舒适性时空变化的关键因素之一。本文开发了一种新颖的建模框架，可以基于几何特征全面评估邻域的时空热舒适性能。加权时间热舒适性能（TCP _w还提出了将热舒适性结果转换为比较性能标准的度量标准。通用热气候指数（UTCI）是选择作为评估该指标的基准的指数。为了证明所开发框架的实用性，对德黑兰气候区三个形态特征不同的城市地区进行了研究。这些位置的不同几何变量最初是使用地理信息系统（GIS）从现有数据集中提取的。然后，通过耦合能量模拟模型（EnergyPlus）和热舒适性插件（Ladybug），开发了高分辨率的空间模型来模拟邻域的热舒适性。已针对一系列现场测量数据成功验证了该模型。
