1. Introduction
Buildings energy performance depends not only on thermal but
also on electrical factors like:
- the presence of electrical or thermal energy generation from
Renewable Energy Sources (RES) and Combined Heat and Power
(CHP) systems;
- the presence of Building Automation Control Systems (BACS) an
Technical Building Management (TBM) systems.
For promoting the energy performance in buildings, EU Member
States have followed different ways. In particular, in the last
decades various support policies have been put into effect for promoting
locale RES-based generators [1–7].
Moreover, according to the European Performance in Building
Directive (EPBD) 2010/31/EU [8], all EU Member States have
defined methodologies for the calculation of the energy performance
of buildings on the basis of a general framework.
An analysis of the progress toward implementation in European
Countries of the EPBD can be found in [9].
It is important to underline, how the current edition of the EPBD,
differently from the old version (Directive 2002/91/EC [10]), gives
greater importance to automation, control and monitoring systems.
