EN 13201-3 - SR > EIR
Replacement of parameter SR with the new EIR
SR = Surroun d Ratio SR is the horizontal illuminance value of the areas adjacent to the carriageway in relation to the corresponding values present on the carriageway.
Eh av (Strip 1) + Eh av (Strip 4) SR = ____________________________ Eh av (Strip 2) + Eh av (Strip 3)
EN 13201:2015 – New features
EN 13201-3 - SR > EIR
Replacement of parameter SR with the new EIR
EIR = Edge Illum inance Ratio - REI The EIR is the minimum from the evaluation on each side of the carriageway of the ratio of the average horizontal illuminance on the longitudinal strip adjacent to the edge of the carriageway, and lying off the carriageway, divided by the average horizontal illuminance on the corresponding longitudinal strip lying on the carriageway

EN 13201-3 – Miscellaneous
The EN 13201-3:2015 Standard also includes the following new features:
Flow-chart of the different parameter calculations (Eh, L, f TI, REI ….)
Clear definition of variables
EN 13201:2015 – New features
EN 13201-4 – Field measurements
The new EN 13201-4:2015 Standard introduces:
The concept of approximate value
Field Measurement uncertainty evaluation
The measurement uncertainty can be considered as having three groups of components: ♦
The metrological characteristics of the measurement system and the influence of measurement procedures
♦
The influence of the nominal characteristics and layout of the road lighting installation being measured
♦
The influence of the instantaneous characteristics of the road lighting installation being measured, and of the weather and environmental conditions
EN 13201:2015 – New features
EN 13201-5 – Energy Performance Indicators
The new EN 13201-4:2015 Standard introduces the assessment of the energy performance of a particular lighting system through 2 specific indicators:
DP - PDI - Power Density Indicator
DE - AECI - Annual Energy Consumption Indicator
They apply for all traffic areas covered by the series of Classes M, C and P as defined in EN 13201-2 Both parameters shall be always presented and used together
EN 13201:2015 – New features
EN 13201-5 – Energy Performance Indicators
The new EN 13201-4:2015 norm introduces the assessment of the energy performance of a particular lighting system through 2 specific indicators:
DP - PDI - Power Density Indicator DP
P ________ = i = n area i=1
Ei av Ai
[ W / ( lx • m2 ) ] It corresponds dimensionally to the inverse of luminous efficacy [lm/W]
EN 13201:2015 – New features
EN 13201-5 – Energy Performance Indicators
DE determines the power consumption during the year according to the areas being illuminated and the regulation systems used
DE - AECI - Annual Energy Consumption Indicator j = m periods
DE =
P j t j j = 1 ___________ A
[ W • h / m2 ]
EN 13201:2015 – New features
EN 13201-5 – Energy Performance Indicators
DE is a very useful indicator to help check the regulation systems efficacy in installations with respect to those without (full power operation)
Full power operational profile without regulation systems
Bi-power profile
Tri-power detector-driven operational profile
EN 13201:2015 – New features
EN 13201-5 – Energy Performance Indicators
EN 13201-5:2015 introduces 2 additional metrics to help find the best energy saving solution:
inst –
Installation luminous efficacy inst
=
CL • f M • U • RLO •
This parameter is useful to define the installation luminous efficacy: the higher, the better
[ lm / W ]
q inst – Installation lighting factor
This parameter helps lighting designers to find the best luminance solution with the lowest illuminance value according to the lighting class M selected qinst > 1 for a good result
