ABSTRACT
This paper examines Bulgarian lighting energy consumption sector by sector and set in relation to the Bulgarian national electricity consumption. The technical energy savings potential for lighting in various sectors is examined (industry, residential, commercial and public buildings, transport, agriculture, building communication, and street lighting).
Street lighting receives high priority because of the large cost-effective savings potential. The strategy is to replace mercury lamps with sodium lamps and compact fluorescent lamps. The paper also presents an extensive end-use lighting metering study for the residential sector. This study was the first ever in Bulgaria and helps greatly in assessing the savings potential in the residential sector, but also gives a good view on the importance of peak power consumption in this sector.
Detailed sub-sector data for industrial lighting is given and various savings strategies are presented.
