According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. Introduction
The purpose of this European Standard is to define energy performance indicators for road lighting installations. The standard introduces two metrics, the power density indicator (PD1) D P and the annual energy consumption indicator (AECI) De that should always be used together.
To quantify the potential savings obtainable from improved energy performance and reduced environmental impact, it is essential to calculate both the power density indicator (D P ) and the annual energy consumption indicator (De). In addition, the installation luminous efficacy (ijinst) can be used for comparing the energy performances of alternative road lighting installations.
Careful choice of lighting class(es) during the design and specification phase will help to maximize energy savings by ensuring only the necessary levels of illumination provided at the correct times and for the minimum periods necessary. Additional guidance is given in the CEN/TR 13201-1 with regard to the visual needs of road users, e.g. under varying traffic volumes during certain times of night or under varying weather conditions.
During the design phase of a road lighting installation care should be taken to ensure that the design criteria specified in EN 13201-2 are achieved but that excess overlighting is reduced to the minimum technically obtainable. Overlighting can be minimized by the careful selection of the luminaire and light source but the specified lighting class, the designed lighting point spacing and uniformity ratios are all determining factors of the luminous flux emitted by the light source and thus the power of the light source required. However, this precise luminous flux may not, in reality, exist. Where the luminous flux of the light source is greater than that required the designer can by means of continuously variable control gear, compensate for this effect by reducing the luminous flux of the light source to the required level resulting in lower energy consumption. The same principles and control gear can be used to compensate for changes in luminous flux emitted throughout the lifetime of the light sources.
The energy levels calculated using this standard should not be used as a direct input for the calculation of the load on the electrical distribution system. Such calculations are normally based on the energy requirement derived directly from the lighting and electrical design.
Examples of operational profiles and examples of calculation of the energy performance indicators are provided in Annex A. Typical values of energy performance indicators are provided to illustrate the energy performance of recent technological level of luminaires and installations.
Annex Lighting factor of an installation, as introduced in Annex C, can be additionally used to characterize the energy performance of road lighting installations independently on the lighting components used. Other factors and parameters having influence to the energy performance, such as the maintenance factor (see CIE 154), can be recognized but are not dealt with in this standard.
Recommendations on presentation of the energy performance indicators are provided in Annex D. 1 Scope
This part of the European Standard defines how to calculate the energy performance indicators for road lighting installations using the calculated power density indicator (PDI) Dp and 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.
