The available statistical data are split by region in the reference source. In the statistical tables the regional data are merged considering three different groups of regions, each characterised by a range of heating degree-days (see the table below). The following criterion has been taken into account for the grouping: a region is assigned to a specific zone if it presents the highest number of municipalities having a number of heating degree-days falling in that climatic zone.

CLIMATIC ZONE	HEATING DEGREE-DAYS	ITALIAN REGIONS
Mediterranean	Up to 2100	Abruzzo, Basilicata, Calabria, Campania, Lazio, Liguria, Puglia, Sardegna, Sicilia, Toscana
Middle	From 2100 to 3000	Emilia Romagna, Friuli Venezia Giulia, Lombardia, Marche, Molise, Piemonte, Umbria, Veneto
Alpine	More than 3000	Trentino Alto Adige, Valle d’Aosta
