Talk Title
 Household energy expenditure: segmentation procedure with a focus on energy poverty

Talk Abstract
 

A large part of the primary energy consumption in the different countries is related to the residential sector. For this reason, a precise understanding of the relationships between the household characteristics (i.e., building factors, socio-demographic variables and appliances) and the energy consumption/energy expenditure may serve as basis for policymakers when planning investments aiming to reduce the primary energy consumption and the carbon emission at the “country-scale”. In the broader framework of energy consumption at the household level, energy poverty affects an increasing number of households in Italy, as in the rest of Europe. This work contributes to the present-day discussion of the two above-mentioned research fields: energy consumption in the residential sector and energy poverty. In particular, the Italian case is analysed, by analyising “cross-section” data with a “bottom-up” procedure. The proposed analysis has been divided into two phases: first, a segmentation of the Italian families has been applied, by using a segmentation-tree approach coupled with a regression study; second, energy poverty indicators have been applied to the household segmentation. In particular, both indicators taken form the literature and a novel indicator (based on the minimum thermal comfort-constrain) have been used. The main outcome of this study is the application of energy poverty indicators to the different clusters, in order to identify vulnerable households in Italy. This work would contribute to the community devoted to the broader framework of “the human dimensions of energy use.

Short Biography

Dr. Giorgio Besagni is a Researcher at Ricerca sul Sistema Energetico, a publicly-controlled research center focused on national strategic projects. He obtained a M.S. degree, in energy engineering, and a Ph.D, in Energy and Nuclear Science and Technology, at Politecnico di Milano. During his Ph.D and Post-Doc activities he spent guest stays at HZDR (Germany) in the Computational Fluid Dynamics group and at Ricerca sul Sistema Energetico (Italy). He was teaching assistance at Politecnico di Milano and, in addition, he collaborated with Eni Spa (downhole sour gas separation), Ricerca sul Sistema Energetico (PASSAM European project) and HZDR (experimental and numerical studies of multi-phase flows). In November 2016, he moved in the innovation centre of a commercial-refrigeration company as an R&D engineer, where he studied, experimentally and numerically, innovative refrigeration systems. From July 2017, he is a Researcher at Ricerca sul Sistema Energetico. He is author of more than 50 publications among international journals, book chapters and conference proceedings. He is associate editor for Journal of Cleaner Production, in the editorial board of Renewable Energy and ENERGY Journals, associate editor for Energy, Ecology and Environment, assistant editor for Renewables: Wind, Water, and Solar, assistant editor for International Journal of Energy and Environmental Engineering, Guest Editor for ChemEngineering and ENERGY Journals. In addition, he acts as a reviewer for numerous international Journals. His main research areas concern (i) innovative renewable energy-based technologies (i.e., ejector systems, multi-source heat pumps, innovative storage systems, …), (ii) CFD and lumped parameter modeling of energy system components (i.e., fuel cells and ejector systems), (iii) modeling of refrigeration systems (i.e., commercial refrigeration, solar cooling and ejector-based systems), (iv) experimental and numerical investigations of multiphase flows and (v) energy poverty.
