Classification of italian national territory into climatic zones independent from their geographical location in order to limit the energy consumption by heating plants
The table shows for each climatic zone (A-F) the period in the year and the maximum number
of hours per day when heating may be switched on. In case of severe weather each municipality
may permit heating in different periods. The degree-day is the unit used to assign a climatic zone
to each municipality: it is the sum, extended to all days in a conventional annual heating period,
of positive differences between interior temperature (conventionally fixed at 20?C) and the
mean daily external temperature. As an example the table shows the climatic zones of all
municipalities which are chieftown of their province: for all other 8100 italian municipalities
please consult the proper page.
