BS EN 13201-5:2015定义了如何计算道路的能源性能指标 使用计算出的功率密度指示器（PDI）和计算出的年功率密度 能耗指示器（AECI）DE。功率密度指示器（DP）显示所需的能量 用于道路照明装置，同时满足中规定的相关照明要求 EN 13201-2。年度能耗指标（DE）决定了运行期间的能耗 一年中，即使相关照明要求在夜间或季节发生变化。这些指标可用于比较不同道路照明解决方案的能源性能 以及同一道路照明项目的技术。道路照明系统的能源性能 不同的道路几何形状或不同的照明要求无法相互比较 由于能源性能直接受到待照明区域几何结构等因素的影响， 以及照明要求。功率密度指标（DP）和年能耗 指示器（DE）适用于中定义的M、C和P类照明系列覆盖的所有交通区域 EN 13201-2。交叉引用:EN 12665:2011EN 13201-2EN 13201-3:2015CEN/TR 13201-1EN 13201-4CIE S 017/E: 2011CIE 115:2010CIE 144:2001CIE 154:2003购买时可用的所有当前修订版均包含在本文件的购买中。

BS EN 13201-5:2015 defines how to calculate the energy performance indicators for road lighting installations using the calculated power density indicator (PDI) DPand the calculated annual energy consumption indicator (AECI) DE. Power density indicator (DP) demonstrates the energy needed for a road lighting installation, while it is fulfilling the relevant lighting requirements specified in EN 13201-2. The annual energy consumption indicator (DE) determines the power consumption during the year, even if the relevant lighting requirements change during the night or seasons.These indicators may be used to compare the energy performance of different road lighting solutions and technologies for the same road lighting project. The energy performance of road lighting systems with different road geometries or different lighting requirements cannot be compared to each other directly, as the energy performance is influenced by, amongst others, the geometry of the area to be lit, as well as the lighting requirements. The power density indicator (DP) and annual energy consumption indicator (DE) apply for all traffic areas covered by the series of lighting classes M, C and P as defined in EN 13201-2.Cross References:EN 12665:2011EN 13201-2EN 13201-3:2015CEN/TR 13201-1EN 13201-4CIE S 017/E:2011CIE 115:2010CIE 144:2001CIE 154:2003All current amendments available at time of purchase are included with the purchase of this document.
