Article 2, (12): ' energy performance certi cate ' means a certi cate recognised by a Member
State or by a legal person designated by it, which indicates the energy performance of a building or
building unit, calculated according to a methodology adopted in accordance with Article 3.

Article 4, Para. 2: “ MS may decide not to set or apply the requirements referred to in paragraph
1 to the following categories of buildings: (a) buildings officially protected as part of a designated
environment or because of their special architectural or historical merit, in so far as compliance
with certain minimum energy performance requirements would unacceptably alter their character
or appearance; (d) residential buildings which are used or intended to be used for either less than
4 months of the year or, alternatively, for a limited annual time of use and with an expected energy
consumption of less than 25 % of what would be the result of all-year use; (e) stand-alone
buildings with a total useful floor area of less than 50 m 2 ” .
