Since the objective of this Directive, namely to reduce the energy needed to meet the energy demand associated with the typical use of buildings, cannot be sufficiently achieved by the Member States but can rather, by reason of the guaranteed consistency of shared objectives, understanding and political drive, be better achieved at Union level, the Union may adopt measures in accordance with the principle of subsidiarity as set out in Article 5 of the Treaty on European Union. In accordance with the principle of proportionality as set out in that Article, this Directive does not go beyond what is necessary to achieve that objective.
