【摘要】：随着城市化进程的加快,办公建筑的数量急剧增多,其能耗问题也日益严重,已经成为当前设计师关注的一个问题。而在办公建筑整个全生命周期中,人工照明能耗中占了很大比例,因此如何减少人工照明能耗成了设计师亟待解决的热点问题之一。近年来,许多设计师都把天然采光作为办公建筑节能的新策略,天然采光在办公建筑中的运用也越来越广泛。从节能经济的角度看,天然采光绿色节能无污染,具有可持续性；从舒适性角度看,天然光具有其他任何光源所不能拥有的优点,被认为是影响使用者对建筑环境满意度的重要物理条件。但是天然采光也有不足,如过量天然光进入室内容易产生眩光、过亮等问题,影响办公室内光舒适感。同时,天然采光受天气影响也较大,如阴天条件下为了能够正常办公,不得不开启人工照明。办公室几乎是人们除了住宅外一天呆的时间最长的场所,办公室内光环境舒适与否将直接影响室内办公人员的心情和办公效率,所以将办公室内天然采光设计和室内人工照明设计结合起来研究,意义重大。基于以上分析,本文首先从光舒适角度出发,对南京地区典型商圈办公建筑和旧式办公建筑室内光环境进行了实地调研和测量,并且通过网络问卷的方法对全国来自11个省份的办公人员的光舒适主观感受进行了调研。通过调研分析,探讨了当前我国办公建筑室内光环境存在的问题和不足,同时还了解到了办公人员对室内光舒适的主要关注点有哪些,由此确定了本文研究内容的必要性。其次,在调研的基础上,本文对室内采光的相关理论计算文献进行了整理,明确了影响室内光环境的主要因素,并利用光模拟软件Desktop Randiance对这些因素逐一进行了模拟。为了得到一个适用于南京地区的最优化综合解决方案的参数,本文采用了正交实验法进行分析。在分析基础上明确了将自动控制遮阳百叶和人工智能调光系统整合到一起的基于光舒适的优化节能模型方案,并且利用Energyplus能耗模拟软件验证了该模型在南京地区的适用性和节能率,利用MATLAB仿真软件Simulink验证了该模型系统的可行性,同时还分析了本文提出的模型存在的一些问题并对解决方案进行了探讨。最后,总结和概括了全文的研究内容、创新点和将来要进一步研究的方向,为后续深入研究奠定了基础。本文的研究表明,基于光舒适的办公建筑光环境优化节能模型在南京地区是可行的,也是必要的。在办公建筑中运用该模型可以提高室内办公人员舒适性,同时还能节约20%以上的能耗。
[Abstract]:With the acceleration of urbanization, the number of office buildings is increasing rapidly, and its energy consumption is becoming more and more serious, which has become a problem that designers pay close attention to. In the whole life cycle of office buildings, artificial lighting energy consumption accounts for a large proportion, so how to reduce the artificial lighting energy consumption has become one of the hot issues to be solved by designers. In recent years, many designers regard natural lighting as a new strategy of energy saving in office buildings, and the application of natural lighting in office buildings is more and more extensive. From the economic point of view, natural lighting is environmentally friendly and sustainable; from a comfort point of view, natural light has advantages that no other light source can have. It is considered to be an important physical condition affecting the user's satisfaction with the building environment. However, natural lighting also has shortcomings, such as excessive natural light into the room easily produce glare, too bright and other problems, affecting the comfortable light in the office. At the same time, natural lighting is also affected by the weather, such as overcast conditions in order to be able to normal office, have to turn on artificial lighting. The office is almost the place where people spend the longest time in a day, except the residence. Whether the office is comfortable or not will directly affect the mood and efficiency of the office staff. Therefore, it is of great significance to combine the natural lighting design in the office with the indoor artificial lighting design. Based on the above analysis, this paper firstly investigates and measures the indoor light environment of typical office buildings and old office buildings in Nanjing from the angle of light comfort. And through the method of network questionnaire, the subjective feeling of light comfort of office workers from 11 provinces is investigated. Through investigation and analysis, this paper discusses the existing problems and shortcomings of indoor light environment of office buildings in our country, at the same time, it also finds out the main concerns of office personnel on indoor light comfort, which determines the necessity of the research content of this paper. Secondly, on the basis of investigation and research, this paper collates the relevant theoretical calculation documents of indoor lighting, and clarifies the main factors that affect the indoor light environment, and simulates these factors one by using the optical simulation software Desktop Randiance. In order to obtain the parameters of an optimal comprehensive solution for Nanjing area, the orthogonal experiment method is used to analyze. On the basis of analysis, the optimal energy-saving model based on light comfort is defined, which integrates automatic control shading shutter and artificial intelligence dimming system. The applicability and energy saving rate of the model in Nanjing are verified by Energyplus energy consumption simulation software, and the feasibility of the model system is verified by MATLAB simulation software Simulink. At the same time, some problems in the model proposed in this paper are analyzed and the solutions are discussed. Finally, the research contents, innovation points and future research directions are summarized and summarized, which lays a foundation for further research. The research in this paper shows that the energy saving model of office building based on optical comfort is feasible and necessary in Nanjing area. The application of the model in office buildings can improve the comfort of indoor office workers and save more than 20% of energy consumption.
