Energy efficiency constitutes one of the five dimensions of the European Commission's Energy Union Package 1, designed to enhance energy security, sustainability and competitiveness.
European energy policy is reflected in several Directives; the present document focuses on two main Directives concerning the efficient use of energy in buildings (Directive 2010/31/EU Energy Performance of Buildings - EPBD) and national energy systems (Directive 2012/27/EU Energy Efficiency Directive - EED).
