BIM环境下集成用户行为的建筑能耗预测

Building Energy Consumption Prediction Integrated Occupant Behavior Under BIM Environment

随着建筑能耗在社会总能耗中占比持续增长,世界各国愈加重视对建筑能耗的预测分析与运营控制。目前,考虑用户行为影响的研究多集中在建筑的运营阶段,设计阶段则相对不足。为在设计阶段集成用户行为以准确预测建筑能耗,本文首先将用户行为分为移动行为和用能行为。采用事件机制分析移动行为,通过BIM模型和Agent技术建立基于事件的用户移动行为模型。在此基础上,建立用户用能行为模型,模拟室内环境、人员和设备三者之间的交互作用,获取室内人员和设备运行工况的时间序列信息。最后,以武汉市某办公建筑为例分析建筑能耗,结果表明,与传统方法相比,本文方法所得到的能耗预测值更接近于实测值。

As building energy consumption continues to grow in total social energy consumption,countries around the world are paying more attention to predictive analysis and operational control of building energy consumption.At present,the study of occupant behavior is mainly concentrated in the operational phase of the building,while the design phase is relatively insufficient.In order to accurately predict the building energy consumption during the design phase,this paper divides occupant behavior into mobile behavior and occupants energy behavior.Event mechanism is applied to analyze the mobile behavior,and an event-based occupants behavior model is established through BIM model and Agent technology.On this basis,the occupant energy behavior model is established to simulate the interaction between the indoor environment,occupants and devices,and to obtain time series information of indoor occupants behavior and devices operating conditions.Finally,an office building in Wuhan is taken as an example to analyze the energy consumption of buildings.The results showed that compared with the traditional method,the energy consumption prediction value obtained by this method is closer to the measured value.
