Sample Survey on indoor lighting needs and consumption in Italy: tertiary sector

Maria Rosaria Alabiso*, Walter Bruno Grattieri* NEWSLETTER di IEA Annex 45 "Energy Efficient Electric Lighting for Buildings" N. 7 Maggio 2008 * CESI RICERCA This newsletter highlights the results of a sample survey on indoor lighting needs and energy consumption in the Tertiary sector, carried out in 2004 in Italy. The study focused on a sample of buildings, for which typical features were individually assessed, in particular both the lighting needs (number, type, and operation hours of lamps installed) and the corresponding electricity consumption. The analysis was developed across several branches of the Tertiary, to the aim of estimating the potential savings obtainable with enhanced energy efficiency in the premises with the largest number of lighting points and greater lighting hours (Retail, Office, Hospital, Hotel, Education, …). The result of the work provides indications on the existing stock of lamps and on the average specific consumptions, by users and light source, jointly to the estimate of the potential savings made possible by the best lighting technologies.
