20.500.12556/RUL-136097 Sustainable exterior lighting for cultural heritage buildings and monuments The improper illumination of cultural heritage buildings and monuments can be a source of enormous light pollution, which can have a major impact on the overall environment of the illuminated area. Such lighting can be the result of carelessness or a poorly designed lighting system. This paper presents one of the methodologies that can significantly reduce light pollution, especially spilt light out of building façades. The methodology is based on using luminaires with specially made shutters and an appropriate silhouette of the object. The shutters are designed with the help of photos of the object and the location’s sizes measured. The methodology was tested during the renovation of the lighting systems of different churches in Slovenia and is described using the example of the Church of St. Thomas near Ptuj, Slovenia (N 46°28.9554′, E 16°0.7416′). The results show that the methodology is effective and can significantly reduce light pollution that occurs when such buildings are incorrectly lit. light pollution silhouette shutter cultural heritage lighting optimized exterior lighting svetlobno onesnaženje silhueta zaslonka osvetlitev kulturnih spomenikov optimalna zunanja razsvetljava true false true Angleški jezik Slovenski jezik Članek v reviji 2022-04-12 15:05:42 2022-04-12 15:05:43 2022-09-15 04:13:23 0000-00-00 00:00:00 2021 0 0 15 str. iss. 18, art. 10159 Vol. 13 Sep. 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 628.971 2071-1050 10.3390/su131810159 76161027 RAZ_Kobav_Matej_Bernard_2021.pdf RAZ_Kobav_Matej_Bernard_2021.pdf 1 92C49B4B066B718D72A6B24766FBF925 f95fc5ff568e1e744aa8a8530b45da6bf2e98f25f5cf04721de8cc1a96d935a5 9489c0e7-ba61-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=155562 https://www.mdpi.com/2071-1050/13/18/10159 1 35a900d4-ba61-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=155561 Fakulteta za elektrotehniko 0 0 0
