IDENTIFYING CONSUMERS’PROFILES CONCERNING RESIDENTIAL LIGHTING

Reducing electricity consumption, by decreasing residential light- ing, falls in the range of measures aimed to save 20% of primary energy consump- tion in European Union, up to 2020, and further to improve energy efficiency after 2020. Public lighting and appliances is about 14 % of total electricity consump- tion, in Romania. New energy efficient lighting technologies might contribute to a substantial decreasing of household electricity consumption. Data set used to ap- ply the scientific methodology presented in the paper was gathered in a survey re- search, aiming to investigate Romanians attitude and behavior about lighting con- sumption in households. The goals of this research paper are both to identify the factors associated with the replacement of old incandescent lamps, with the new energy efficient compact fluorescent lamps and light emitting diodes, and to identi- fy Romanian typologies of consumers and the patterns of their behavior. In order to accomplish the research goals, a model of analysis, based on Cluster Analysis and Multiple Correspondence Analysis methods has been proposed in the paper.
