In building energy research, there is a lack of behavioral models for understanding energy consumption of large apartment buildings. This study aims to understand energy use characteristics and influential behavioral factors in the dormitory buildings, a type of large apartment buildings with dense occupancy condition. The study collected the monthly electricity data of 620 rooms within two large dormitory buildings in a university campus located in the hot summer-cold winter climate region for two consecutive years (2018-2019) and administered a questionnaire survey concerning the usage of three common domestic appliances: computer, electric water heating, and air conditioning. Based on a hierarchical multiple regression model, these behaviors accounted for 74.8% and 73.1% of electricity consumption in the years of 2018 and 2019, respectively. Significant differences were found for different genders, floors, and room orientations. Male students consumed more electricity due to a more frequent use of computers; lower floors were more energy intensive due to poorer environmental conditions; south-facing rooms consumed more electricity in summer while north-facing rooms consumed more electricity in winter. This study provides a validated behavioral model for devising potential energy saving measures and also proposes effective strategies for designing and managing the dormitory buildings in the hot summer-cold winter climate region.

在建筑能耗研究中，缺乏用于理解大型公寓建筑能耗的行为模型。这项研究旨在了解宿舍建筑中的能源使用特征和影响行为因素，宿舍建筑是一种居住条件密集的大型公寓建筑。这项研究连续两年（2018-2019）收集了位于炎热的夏季-寒冷的冬季气候地区的大学校园内两所大型宿舍楼内620间客房的每月电力数据，并进行了关于三种常见家庭使用情况的问卷调查电器：计算机，电热水和空调。基于分层多元回归模型，这些行为分别占2018年和2019年用电量的74.8％和73.1％。发现不同性别，楼层和房间方向的显着差异。男学生由于更频繁地使用计算机而消耗了更多的电；由于环境条件较差，较低的楼层需要更多的能源；朝南的房间在夏天消耗更多的电力，而朝北的房间在冬天消耗更多的电力。这项研究为设计潜在的节能措施提供了经过验证的行为模型，并且提出了在炎热的夏季寒冷的冬季气候区域设计和管理宿舍建筑的有效策略。朝南的房间在夏天消耗更多的电力，而朝北的房间在冬天消耗更多的电力。这项研究为设计潜在的节能措施提供了经过验证的行为模型，并且提出了在炎热的夏季寒冷的冬季气候区域设计和管理宿舍建筑的有效策略。朝南的房间在夏天消耗更多的电力，而朝北的房间在冬天消耗更多的电力。这项研究为设计潜在的节能措施提供了经过验证的行为模型，并且提出了在炎热的夏季寒冷的冬季气候区域设计和管理宿舍建筑的有效策略。
