Outdoor Thermal Comfort (OTC) is largely influenced by urban morphology and geometry of the urban landscape. In this study, the Local Climatic Zones (LCZs) approach was adopted to assess the OTC in different settings of Sriniketan-Santiniketan Planning Area (SSPA) during the summer season. The basic objective of this study is to assess OTC from both subjective and objective perspectives over eight LCZs. This study assessed OTC over LCZs using both field measurements and questionnaire survey. Non-parametric tests such as ANOVA and Kruskal-Wallis tests were also performed to find out the significant difference of perception across LCZs. The result of ANOVA and Krushkal-Walls test showed that subjective perception of OTC across LCZs varied due to diversified physical landscape settings. The result also showed that the maximum (above 40°C) and minimum (28°C) temperature was recorded in built types (particularly compact low rise) and natural land cover types (dense forest and water) respectively. Highest PET was also recorded over the built-up LCZs (about 50°C) that led to this planning region thermally very hot or extreme heat stress. The respondents living in LCZ₃ and LCZ₆ were more sensitive to the thermal sensation as compared to those living in other LCZs.This study was probably the first attempt dealing with the assessment of OTC over the tropical planning region using LCZ approach from subjective and objective perspectives. Therefore, this research study has an immense potentiality to formulate strategies to deal with the outdoor thermal conditions as well to implement climate sensitive planning for urban sustainability in tropical cities.

户外热舒适度（OTC）在很大程度上受城市形态和城市景观几何形状的影响。在本研究中，在夏季，采用了局部气候区（LCZs）方法来评估Sriniketan-Santiniketan规划区（SSPA）不同环境中的OTC。这项研究的基本目标是从八个LCZ的主观和客观角度评估OTC。这项研究使用现场测量和问卷调查评估了LCZ上的OTC。还进行了诸如ANOVA和Kruskal-Wallis检验之类的非参数检验，以发现跨LCZ的感知的显着差异。方差分析和Krushkal-Walls检验的结果表明，由于自然景观设置的多样性，跨LCZ的OTC的主观感知也有所不同。结果还表明，分别以建筑类型（尤其是紧凑的低层建筑）和自然土地覆盖类型（茂密的森林和水）记录了最高温度（40°C以上）和最低温度（28°C）。在堆积的LCZ（约50°C）上也记录了最高的PET，导致该规划区域受到非常热或极高的热应力。居住在LCZ的受访者与其他LCZ相比，LC ₃和LCZ ₆对热感更敏感。本研究可能是从主观和客观角度使用LCZ方法处理热带计划区域OTC评估的首次尝试。因此，这项研究具有巨大的潜力来制定应对室外热条件的策略，并为热带城市的城市可持续性实施气候敏感型计划。
