dc.description.abstractIn general, lighting systems are subjected to verification of photometric parameters after installation what is usually performed by field trial according to lighting project as required by the standard EN 12464-1. Illumination of indoor workplaces is normally based only on artificial lighting without access of daylight through windows or rooflights. To achieve good visual performance for workers, higher illuminance level at the workplace is required. Moreover, in some countries these requirements to photometric parameters shall follow legislative documents which prescribe illuminance level at the workplace. In Slovak Republic the legal requirement for total maintained illuminance is 1 500 lx for indoor workplaces without daylight if any alternative arrangements are not ensured for the workers and long-term stay of persons is declared at the workplace what should reduce health impact of the persons in that space without daylight. This is controlled by the Public Health Authority as one of the requirements for commissioning of the building. More luminaires with appropriate light sources can easily satisfy that illuminance level. But on the other hand, energy consumption for this lighting system is much higher what negatively influences the classification according to the system for energy performance of buildings as requirement of the EU directive 2010/31/EC.Requirements for lighting systems are stated in the document EN 15193. This paper puts focus on workplaces without access of any daylight. Measurements of photometric parameters of lighting systems were performed with respect to the energy performance of building according to requirements of the standard EN 15193. Based on analyses of the results energy performance of lighting systems will be figured out. Suggestions to possible options how to satisfy legislative and normative requirements with respect to lighting systems used in illumination of indoor workplaces will be also presented.en
