2015 will see the release of the European Lighting Standard EN13201. This paper will give a very brief overview of the proposed changes. EN13021 part 5 covers energy calculation to allow the designer in new designs and asset managers to evaluate the installations and draw comparisons previous or existing installations. Talk by Nick Smith, Nick Smith Associates Ltd

2. EN13201 also known as CEN
• Comes in 5 parts being revised
• PD CEN/TR 13201-1:2014
– Road lighting - Selection of lighting classes
• prEN13201-2 : 2015 (being finalised)
– Road Lighting - Performance Requirements
• prEN13201-3 : 2015 (being finalised)
– Road Lighting - Calculation of performance
• prEN13201-4 : 2015 (being finalised)
– Road Lighting -Methods of Measuring Lighting Performance
• prEN13201-5 : 2015 (New)
– Energy efficiency indicators
#

3. How does one find the best lantern
• In days gone by
– Price
– Spacing
– Wattage
– Ease of installation
• Now
– Wattage
– Price
– Spacing
prEN13201-5 :2015
Power performance indicators
#

4. prEN 13201-5:2015 originally
2 metrics; 1 for Engineers; 1 for politicians!
• Power Density Calculation
– Watts / lux / m2
• AECI – Energy Consumption Indicator
– kWh/m2
However
#

5. prEN 13201-5:2015
• Are politicians really interested in street lighting
• Power Density Calculation
– Watts / lux / m2
– Power density indicator for an area divided into sub-areas for
a given state of operation shall be calculated
– Consider variable spacing and levels
– Why do we need it?
Based on the 2015 early draft please consult the final publication. #

6. Variable profile
Make the calculation
more complex
#

7. • AECI – Energy Consumption Indicator
– kWh/m2
• The annual electricity consumption of a road lighting installation
depends on
– the period of time for which lighting is provided,
– the lighting class specified by the relevant lighting standard for each lighting
period,
– the efficiency of the lighting installation, when providing the necessary
lighting for each period,
– the way the lighting management system follows the change in visual needs
of road users,
– the parasitic energy consumption of lighting devices during the period when
the lighting is not needed.
• Are politicians really interested in street lighting
prEN 13201-5:2015
Based on the 2015 early draft please consult the final publication. #

8. Power Density An Example,
The Brief
• 10m columns.
• Single sided arrangement.
• The client also wanted to use LED.
• Two electrical circuits
– So columns are on alternate circuits.
#

9. Options
• Three question
• Does the road need to be lit at all?
– The decision to light or not light is based on usage
– Where are the risk assessments?
– Advise the client of their duties under CDM
• M class
• P class
