Figure 24: A high amount of light is directed to the houses and is wasted<br />

For <strong>street</strong> <strong>lighting</strong> the <strong>lighting</strong> performance requirements are imposed by European standards<br />

per road class (EN 13201-2: Road <strong>lighting</strong>) (see also chapter 1). These performance<br />

requirements are quality requirements related to light levels, uniformity and glare but does not<br />

include any energy performance requirements.<br />

The performance of energy consumption for <strong>street</strong> <strong>lighting</strong> with illuminance requirements<br />

(defined category S in chapter 1) is mainly dependent on 2 factors:<br />

1. Configuration (implantation) of light points.<br />

This is also very diverse in Europe because of different local conditions. Luminaires can be<br />

attached to own poles, walls, cables or electricity distribution poles. Poles can also be<br />

installed in many different configurations (single side, middle, zigzag,..) (see also chapter<br />

3) with many heights and interdistances.<br />

2. The luminaire performance itself.<br />

The performance of energy consumption for <strong>street</strong> <strong>lighting</strong> with luminance requirements<br />

(category F and M in chapter 1) is mainly dependent on 3 factors:<br />

1. The road surface reflection.<br />

2. Configuration (implantation) of light points.<br />

Configurations in Europe are also very diverse because of different local conditions.<br />

Luminaires can be attached to own poles, walls, cables or electricity distribution poles.<br />

Poles can also be installed in many different configurations (single side, middle, zigzag,..)<br />

with many heights, interdistances, luminaire tilt angles. Also the road or surface to be lit can<br />

vary.<br />

3. The luminaire performance itself.<br />

(Marc Gillet (MG), Schréder expert consultation on 3/4/06): 'Because of the many variations in<br />

factors 1,2 and 3’ one luminaire can be tuned in up to 32 configurations with different optical<br />

configurations in his product portfolio. This is according to MG required to suit a particular<br />

environment (factor 1 and 2) and road class requirements (EN 13201-1) with the lowest energy<br />

consumption. Also simply chosing between the few CIE road surface classes in the design<br />
