ABSTRACT The study examines stress indices and occupants’ comfort in a cross-laminated timber school building in the Northeast US in different seasons. The case study has won different awards for its sustainability credentials and use of structural timber for the construction. The environmental parameters were measured in the cold and warm periods. Thermal comfort models were applied to evaluate the occupants’ comfort. The stress indices were computed using the Wet-Bulb Globe Temperature and Universal Thermal Climate Index (UTCI) models. The average internal temperatures of 20.2°C and 22.5°C were measured in the cold and warm periods. In the cold and warm seasons, the mean relative humidity values were 43.6% and 58.3%, respectively. Lower and higher temperatures were noted during the occupied and non-occupied hours, which can cause warm and cold discomfort. The proposed Wet-Bulb Globe Temperature and UTCI in the warm period are 3.4°C and 3.0°C higher than the values computed for the cold season. The overall results showed that no thermal stress is predicted in the spaces. The study recommends that designers should consider thorough assessments before recommending interventions in buildings. The study also suggests that occupants should be enabled to adjust the thermal environment of buildings outside the occupied hours.

美国东北部某木结构学校建筑不同季节的居住者舒适度和压力指数

摘要 该研究调查了美国东北部不同季节的交叉层压木材学校建筑中的压力指数和居住者的舒适度。该案例研究因其可持续性证书和在建筑中使用结构木材而获得了不同的奖项。在寒冷和温暖时期测量环境参数。应用热舒适模型来评估居住者的舒适度。应力指数是使用湿球地球温度和通用热气候指数 (UTCI) 模型计算的。在寒冷和温暖时期测量的平均内部温度分别为 20.2°C 和 22.5°C。在寒冷和温暖季节，平均相对湿度值分别为 43.6% 和 58.3%。在有人居住和非有人居住的时间里，温度越来越低，这会导致温暖和寒冷的不适。暖期建议的湿球温度和 UTCI 比冷季计算值高 3.4°C 和 3.0°C。总体结果表明，在这些空间中没有预测到热应力。该研究建议设计师在建议对建筑物进行干预之前应考虑彻底的评估。该研究还建议，应使居住者能够在居住时间以外调整建筑物的热环境。该研究建议设计师在建议对建筑物进行干预之前应考虑彻底的评估。该研究还建议，应使居住者能够在居住时间以外调整建筑物的热环境。该研究建议设计师在建议对建筑物进行干预之前应考虑彻底的评估。该研究还建议，应使居住者能够在居住时间以外调整建筑物的热环境。
