在比较监测和建模的建筑能量性能时，建筑物居住者的适应行为和热反应可能是导致重大不确定性的原因。更好地了解居住者和他们的建筑之间的相互作用对于管理这种不确定性和减少预测能源使用量和实际能源使用量之间的差异(通常称为“性能差距”)是必要的。本文介绍了在严冬暖夏的中国北部城市哈尔滨，对10个混合模式办公室进行夏季纵向调查的结果。这项研究收集了在线每日调查、当地环境的现场测量、居住者的体验和适应性控制行为的数据。通过观察适应行为、物理环境中的热感觉、建筑几何变量和人员特征来分析居住者和建筑之间的相互作用。对行为和情感的驱动机制也进行了研究。结果显示，白天和晚上都有很高的可能性打开窗户，在夏季，伴随着自然通风，很频繁地使用混合冷却方案，包括风扇和空调。办公室内部环境与室外环境的积极互动促使居住者的热感觉与室外物理变量有更多的联系。相对湿度水平是窗户打开的潜在关键预测因素，办公室的几何参数、住户的风扇使用情况和感觉到的热感觉也显示出一定的预测能力。评估居住者感觉和行为相互作用的性质可能会提供信息并改善基于建筑性能的设计结果。
The adaptive behaviour and thermal responses of building occupants can be responsible for significant uncertainties when comparing monitored and modelled building energy performance. A better understanding of the interaction of occupants and their buildings is necessary for managing this uncertainty and reducing discrepancies between predicted and actual energy use (commonly known as ‘the performance gap’). This paper presents the results from a longitudinal study during a summer season of ten mixed-mode offices located in Harbin, a city in northern China, which experiences severe winters and warm summers. The study collected data from on-line daily surveys, field measurements of the local environment, occupants' experiences and adaptive control behaviours. Occupant-building interactions were analysed through observing adaptive behaviour, perceived thermal sensations in the physical environment, architectural geometric variables and personnel characteristics. The driving mechanisms for behaviours and feelings were also studied. The results showed a high probability of window opening for both day and night, and a high frequency of the use of a mix of cooling options, including fans and air conditioning, accompanied by natural ventilation in the summer season. The active interaction of the offices' internal environments with the outdoor environment motivated more connections of occupant thermal feelings with the outdoor physical variables. Relative humidity levels were potential key predictors for window opening, and the geometric parameters of offices, occupants' fan use and perceived thermal feelings also showed a level of predictive ability. Evaluating the nature of occupant feelings and behaviours interactions may inform and improve results from building performance-based design.
