Abstract
The energy need of buildings is strictly related to the local climate and to the construction characteristics (in particular the elements of the building envelope, the ratio between glazed and opaque façade, and orientation). In order to assess the energy performance of different building solutions characterising a large building stock, it can be useful to perform detailed simulation on reference building models. The results obtained can highlight critical issues that are useful for defining adequate policies for improving the built environment. The methodology for characterizing the building energy models, which could constitute a reference for other studies, is described in this chapter as applied in Italy. The set of detailed parameters defining the reference buildings could also be adopted for similar contexts in Southern Europe.

Notes
- 1.
It has to be noted that, under the weekly based point of view, the overall amount of these office internal loads, having considered 5 working days, is quite comparable to the overall amount resulting by considering the lower residential heat loads during all the 7 days.
- 2.
In Italy the heating degree-days values range goes from less than 600, in the national climatic zone A, to over 3000, in the zone F. Nevertheless, buildings are numerically significant in between (zones B–E).
- 3.
The range of constructions characterising tertiary buildings sometimes differ from the ones adopted in residential buildings. However, all the considered “conventional” envelopes represent widely diffuse solutions and can be adopted also when analysing common residential buildings.
