Abstract: LIDC is an important characteristic of luminaires used in the design of new lighting systems. Mirror system goniophotometers with are based on the principle of reflection of light emitted from luminaires on the mirrors. The accuracy of the LIDC measurement is influenced by many factors. This paper deals with measurement errors which occur with this type of goniophotometer, then methods of validation of goniophotometers using a mirror system is proposed. Based on these validation methods,accuracy of the LIDC measurement on goniophotometer with mirror system can be increased. This paper also deals with the impact of the choice of LIDC measured on goniophotometer with mirror system to the quality of interior lighting systems in the framework of the energy performance of buildings. The term energy performance of buildings means the amount of energy needed to meet all the energy needs associated with a standardized usage of the building.
