Lighting planning
Energy efficiency in lighting installations
A lighting installation needs to confirm to the various requirements stipulated for its specific area, without compromising on energy efficiency or visual comfort. This necessitates that care consideration is paid towards the selection of the appropriate lighting system, equipment, control systems and the use of daylight. A measurement of efficiency in a lighting installation is the installed output, in W/m², that is required to meet defined demands.
In addition to a low installed output, energy usage should be limited in an installation with the help of different control systems. A better method of assessing the energy efficiency of a lighting system is to evaluate the annual energy consumption. This method is described in the EN 15193 standard, which is linked to the Energy Directive
General advice for creating a low energy consumption
The following points should be considered in order to create low energy usage in a lighting installation:
Selection of light sources with optimal luminous efficacy for the required colour reproduction.
Energy efficient lighting system with installed lighting output suitable for the required task.
Efficient luminaires with the correct light distribution and good cut-off properties.
Efficient utilisation of daylight.
Efficient utilisation of artificial and natural light through the selection of a light interior colour scheme.
Control of lighting through presence detection.
Possibility of localised control by the individual.
High frequency operation with dimming.
Well planned maintenance of the lighting installation to obtain a high maintenance factor.
