What is BS EN 13201-5-Energy performance indicators for road lightings about?
BS EN 13201-5 is a European standard that covers energy performance indicators for road lighting, ensuring energy efficiency and performance in road lighting maintenance and development applications. BS EN 13201-5 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.
In BS EN 13201-5, the 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.
The indicators in BS EN 13201-5 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 can’t be compared to each other directly, as the energy performance is influenced by the geometry of the area to be lit and 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.
Who is BS EN 13201-5-Energy performance indicators for road lightings for?
BS EN 13201-5 on energy performance indicators for road lightings applies to:
- Manufacturers and suppliers of road lightings
- Dealers and importers of road lightings
- Contractors and infrastructure developers
- Construction, civil and design engineers
- Road maintenance authorities
- Inspection and quality assurance services
Why should you use BS EN 13201-5-Energy performance indicators for road lightings?
By allowing pedestrians and automobiles to see each other, road lighting promotes safety. Careful choice of lighting classes during the design and specification phase will help to maximize energy savings by ensuring only the necessary levels of illumination are provided at the correct times and for the minimum periods necessary.
BS EN 13201-5 provides users guidance on terms, definitions, symbols, abbreviations, power density indicator, annual energy consumption indicator, and operational profiles, enabling the accurate calculation of energy performance indicators. BS EN 13201-5 allows users to quantify the potential savings from the improved energy performance and reduced environmental impact by calculating the power density indicator (DP) and the annual energy consumption indicator (DE).
The adoption of BS EN 13201-5 allows users to assess the energy performance of road lightings, enabling the improvement in energy consumption for achieving cost efficiency and sustainability.
