影响办公建筑照明能耗的因素很多,比如照明的水平、采光状况、照明产品选型及照明设计、照明控制以及使用者的行为习惯等。了解和定量分析各因素如何影响照明能耗以及影响程度,对于指导照明设计具有重要的意义。同时,采光照明设计对于室内热环境和空调采暖能耗也有影响,建筑整体节能设计需要平衡光热两方面的因素。本文从工程实践出发,提出了动态光环境和照明能耗模拟的方法与数学模型,为照明优化设计提供了重要的技术手段。
Many factors affect the energy consumption of office buildings lighting, such as lighting levels, lighting conditions, lighting product selection and lighting design, lighting control and user behavior. Understanding and quantitatively analyzing how each factor affects lighting energy consumption and how much it affects is of great importance to guiding lighting design. At the same time, lighting and lighting design for indoor thermal environment and air conditioning heating energy consumption also have an impact, the overall energy-saving design of the building needs to balance the two factors of light and heat. Based on engineering practice, this paper presents methods and mathematical models for dynamic light environment and lighting energy consumption simulation, which provide important technical means for lighting optimization design.
