DIN V 18599-4 specifies the approved method of verifying the monthly and annual energy use for lighting in non-residential buildings. The method includes the division of a building into zones as required for lighting technology purposes, determination of the specific "electrical evaluation power" of the artificial lighting system, as well as considerations on the way in which daylight is utilized and the effects of presence detection systems. To achieve lighting energy efficiency, suitable lighting and lighting control systems shall be employed and the available daylight shall be utilized to the best possible extent. The method described here only deals with the lighting systems needed to achieve minimum lighting requirements. According to the provisions of DIN EN 12464-1, a lighting system shall be designed in such a way that the lighting requirements of a specific space are met without needlessly increasing the energy use. At the same time, the energy use shall not be reduced to the detriment of the quality of the lighting conditions. DIN V 18599-4 has been approved by NA 005-56-20 GA "Gemeinschaftsarbeitsausschuss NABau/FNL/NHRS: Energetische Bewertung von Gebäuden" ("Joint Working Committee NABau/FNL/NHRS: Energy performance of buildings") and published as a prestandard.
