Thermal comfort research has been traditionally based on cross-sectional studies and spatial aggregation of individual surveys at building level. This research design is susceptible to compositional effects and may lead to error in identifying predictors to thermal comfort indices, in particular in relation to adaptive mechanisms. A relationship between comfort and different predictors can be true at an individual level but not evident at the building level. In addition, cross-sectional studies overlook temporal changes in individual thermal perception due to contextual factors. To address these limitations, this study applied a longitudinal research design over 8 to 21 months in eight buildings located in six countries around the world. The dataset comprises of 5,567 individual thermal comfort surveys from 258 participants. The analysis aggregated survey responses at participant level and clustered participants according to their thermal sensation votes (TSV). Four TSV clusters were introduced, representing four different thermal sensation traits. Further analysis reviewed the probability of cluster membership in relation to demographic characteristics and behavioural adaptation. Finally, the analysis at individual level enabled the introduction of a new metric, the thermal zone (Zt), which in this study ranges from 21.5°C to 26.6°C. The thermal sensation traits and person-centric thermal zone (Zt) are a first step into the development of new metrics incorporating individual perceived comfort into dynamic building controls for adaptive buildings.

舒适的色彩:从热感到以人为中心的热区,以适应建筑策略

传统上,热舒适性研究是基于横截面研究和建筑物各个调查的空间聚集。该研究设计容易受到成分影响,并且可能会导致在确定热舒适指数的预测因子(尤其是与自适应机制相关的预测因子)时出错。舒适度和不同预测变量之间的关系在个人层面上可能是正确的,但在建筑物层面上则不明显。此外,横断面研究忽略了由于环境因素导致的个体热感知的时间变化。为了解决这些局限性,本研究在全球6个国家/地区的8座建筑物中进行了8到21个月的纵向研究设计。该数据集包含来自258位参与者的5,567个独立的热舒适性调查。该分析汇总了参与者级别的调查回答,并根据他们的热感投票(TSV)对参与者进行了聚类。引入了四个TSV簇,代表了四个不同的热感特征。进一步的分析回顾了与人口统计特征和行为适应有关的集群成员资格的可能性。最后,在个人层面进行分析可以引入新的度量标准,即热区(Zt),在本研究中,其温度范围为21.5°C至26.6°C。热感特征和以人为中心的热区(Zt)是开发新指标的第一步,该指标将个人感知的舒适度纳入自适应建筑物的动态建筑物控制中。引入了四个TSV簇,代表了四个不同的热感特征。进一步的分析回顾了与人口统计特征和行为适应有关的集群成员资格的可能性。最后,在个人层面进行分析可以引入新的度量标准,即热区(Zt),在本研究中,其温度范围为21.5°C至26.6°C。热感特征和以人为中心的热区(Zt)是开发新指标的第一步,该指标将个人感知的舒适度纳入自适应建筑物的动态建筑物控制中。引入了四个TSV簇,代表了四个不同的热感特征。进一步的分析回顾了与人口统计特征和行为适应有关的集群成员资格的可能性。最后,在个人层面进行分析可以引入新的度量标准,即热区(Zt),在本研究中,其温度范围为21.5°C至26.6°C。热感特征和以人为中心的热区(Zt)是开发新指标的第一步,该指标将个人感知的舒适度纳入自适应建筑物的动态建筑物控制中。在个人层面上的分析使得能够引入新的度量标准,即热区(Zt),在本研究中,其温度范围为21.5°C至26.6°C。热感特征和以人为中心的热区(Zt)是开发新指标的第一步,该指标将个人感知的舒适度纳入自适应建筑物的动态建筑物控制中。在个人层面上的分析使得能够引入新的度量标准,即热区(Zt),在本研究中,其温度范围为21.5°C至26.6°C。热感特征和以人为中心的热区(Zt)是开发新指标的第一步,该指标将个人感知的舒适度纳入自适应建筑物的动态建筑物控制中。
