人是建筑系统的主动参与者和房间设备的使用者,通过开关窗户、开关窗帘、开关灯、开关空调等动作对房间设备和室内环境进行调节和控制。这些行为决定了房间设备的运行状态,也直接影响建筑室内环境和运行能耗。本文提出一种基于条件触发和分段条件概率函数的室内人员动作描述方法,它能够全面反映人行为随机、环境反馈、事件相关、及不同动作之间关联等特征。以此模型为基础,容易与建筑能耗模拟软件实现集成,对人员动作、设备运行状态、室内环境等进行耦合模拟,从而定量刻画这些行为对建筑室内环境与运行能耗的影响。 People are active participants in building systems and users of room equipment. They regulate and control room equipment and indoor environments by switching windows, switching curtains, switching lights, and switching air conditioners. These behaviors determine the operating status of room equipment and also directly affect the indoor environment of the building and the energy consumption of the operation. This paper presents a description method of indoor personnel action based on condition trigger and piecewise conditional probability function, which can fully reflect the characteristics of human behavior randomness, environmental feedback, event correlation and the correlation between different actions. Based on this model, it is easy to integrate with building energy simulation software to simulate the coupling of personnel movement, equipment operation status and indoor environment so as to quantitatively describe the impact of these behaviors on indoor environment and operation energy consumption.
