Abstract The growing need for planning eco-cities is calling on a tool that can give better prediction of the thermal comfort conditions for a specific microclimate. A multi-nodal thermal regulation model can potentially factor in the impacts of the transient and asymmetric thermal conditions on human subjects. In this study, Human subjects were invited to experience various kinds of urban open spaces and to express their thermal feelings, while skin temperatures of 17 local body segments were measured. We tested the multi-nodal thermal regulation model developed by UC Berkeley by comparing its predictions of human body skin temperature, thermal sensation vote (TSV), and thermal comfort vote (TCV) with our onsite human subject measurements and questionnaire survey, in order to identify the causes of the errors between the prediction and measurements. Corresponding to the thermal neutral status, the field-measured data recorded wider local skin temperature ranges than the simulated ones. We proposed using a “null zone” instead of “set-point” in the thermal comfort model to accommodate the possible adaptation of human subjects to the highly fluctuating wind environment in open spaces. It was proposed that the forehead was counted as one of the dominant local body parts when defining the overall thermal sensation. The correlation coefficient R 2 between the prediction and the field measured TSV improved to 93.7% for the revised model from 76.2% of the original model.

用于室外环境评估的多节点热调节和舒适模型的开发

摘要 对生态城市规划的日益增长的需求正在呼唤一种能够更好地预测特定小气候的热舒适条件的工具。多节点热调节模型可能会考虑瞬态和非对称热条件对人体的影响。在这项研究中，人类受试者被邀请体验各种城市开放空间并表达他们的热感受，同时测量了 17 个局部身体部位的皮肤温度。我们通过将其对人体皮肤温度、热感觉投票 (TSV) 和热舒适投票 (TCV) 的预测与我们的现场人类受试者测量和问卷调查进行比较，测试了加州大学伯克利分校开发的多节点热调节模型，以确定预测和测量之间误差的原因。对应于热中性状态，现场测量数据记录的局部皮肤温度范围比模拟数据范围更广。我们建议在热舒适模型中使用“零区”而不是“设定点”，以适应人类受试者对开放空间中高度波动的风环境的可能适应。有人提出，在定义整体热感觉时，前额被视为主要的局部身体部位之一。修正模型的预测与现场实测TSV的相关系数R 2 从原模型的76.2%提高到93.7%。我们建议在热舒适模型中使用“零区”而不是“设定点”，以适应人类受试者对开放空间中高度波动的风环境的可能适应。有人提出，在定义整体热感觉时，前额被视为主要的局部身体部位之一。修正模型的预测与现场实测TSV的相关系数R 2 从原模型的76.2%提高到93.7%。我们建议在热舒适模型中使用“零区”而不是“设定点”，以适应人类受试者对开放空间中高度波动的风环境的可能适应。有人提出，在定义整体热感觉时，前额被视为主要的局部身体部位之一。修正模型的预测与现场实测TSV的相关系数R 2 从原模型的76.2%提高到93.7%。
