ISO 10916:2014定义了计算方法，用于确定通过垂直立面和屋顶灯穿透非住宅建筑的月和年可用日光量及其对电照明能源需求的影响。它可用于现有建筑以及新建和翻新建筑的设计。ISO 10916:2014提供了与具有日光供应和照明控制装置的电气照明系统的安装功率密度相关的整体照明能量平衡方程式（验证计算方法）。安装功率密度的确定不在本方法的范围内，与占用检测等相关的控制也不在本方法的范围内。如果使用外部电源确定安装功率密度和控制参数，则可以计算照明的内部负荷和照明能源需求本身。然后，在整体建筑能量平衡计算中，可以考虑照明的能源需求和照明的内部负荷:供暖；通风气候调节和控制（包括冷却和加湿）；以及为建筑物的生活热水供应供暖。为了估算日光供应和日光相关人工照明控制系统的额定值，可以使用一个简单的表格-给出了基于遗传算法的计算方法。简单方法描述了根据日光照明工程的需要，将建筑物划分为若干区域，以及如何利用垂直立面系统和屋顶灯提供的日光，以及依赖日光的照明控制系统如何影响能源需求。考虑具有可选着色和灯光重定向属性的动态垂直立面，即允许在直接日照和漫射天空下对立面解决方案进行单独优化。对于屋顶照明系统标准，考虑了棚式屋顶灯和连续屋顶灯等静态解决方案。该方法适用于不同纬度和气候。对于标准建筑区域（使用），提供了运行时间。对于基于计算机的详细分析（综合计算），规定了最低要求。为了支持整体建筑性能评估，提供了整体建筑水平的额外日光性能指标。

ISO 10916:2014 defines the calculation methodology for determining the monthly and annual amount of usable daylight penetrating non-residential buildings through vertical facades and rooflights and the impact thereof on the energy demand for electric lighting. It can be used for existing buildings and the design of new and renovated buildings.ISO 10916:2014 provides the overall lighting energy balance equation relating the installed power density of the electric lighting system with daylight supply and lighting controls (proof calculation method).The determination of the installed power density is not in the scope of this method, neither are controls relating, for instance, to occupancy detection. Provided the determination of the installed power density and control parameters using external sources, the internal loads by lighting and the lighting energy demand itself can be calculated. The energy demand for lighting and internal loads by lighting can then be taken into account in the overall building energy balance calculations: heating; ventilation; climate regulation and control (including cooling and humidification); and heating the domestic hot-water supply of buildings.For estimating the daylight supply and rating daylight-dependent artificial lighting control systems, a simple table-based calculation approach is provided. The simple method describes the division of a building into zones as required for daylight illumination-engineering purposes, as well as considerations on the way in which daylight supplied by vertical facade systems and rooflights is utilized and how daylight-dependent lighting control systems effect energy demand. Dynamic vertical facades with optional shading and light redirection properties are considered, i.e. allowing a separate optimization of facade solutions under direct insolation and under diffuse skies. For rooflighting systems standard, static solutions like shed rooflights and continuous rooflights are considered. The method is applicable for different latitudes and climates. For standard building zones (utilizations), operation times are provided.For detailed computer-based analysis (comprehensive calculation), minimum requirements are specified.To support overall building performance assessment, additional daylight performance indicators on the overall building level are provided.
