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

#

How does one find the best lantern

• In days gone by– Price– Spacing– Wattage– Ease of installation

• Now– Wattage– Price– Spacing

prEN13201-5 :2015Power performance indicators

#

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

#

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. #

Variable profile

Make the calculation more complex

#

• 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 lightingprEN 13201-5:2015

Based on the 2015 early draft please consult the final publication. #

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.

#

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

• All the calculations are dependent of having the right data in the photometric file.

• The future is bright – (depending what Class you choose)

• but a not really
