Energy certification of buildings: A comparative analysis of progress towards implementation in European countries

Share this Post:

The Energy Performance Building Directive has introduced great changes in terms of energy certification of buildings all over Europe, since 2006. It has played an important role in the common policy to monitor and reduce energy consumption.

In order to assess the experience achieved in this field in Europe, and in particular against the highly diverse settings of the different European nations, the "Energy certification of buildings: a comparative analysis of progress towards implementation in European countries" report examines to what extent the Directive has been implemented by the 27 EU Member States. This has been done through a comparative analysis assisted by two different indicators: 'uniformity' and 'excellence'. ‘Uniformity’ assesses how closely a country has kept to the Directive’s aims and guidelines, for instance, if there is an obligation to certify buildings and if methodologies to calculate energy performance have been developed and adopted. The measurement of ‘excellence’ includes, for example, the timing of implementation and the dates that certification began, and the use of measures to enhance energy efficiency that benefit property owners/buyers and landlords/tenants. The ‘excellence’ measurement can be used to identify the ‘best’ performers, i.e. the leaders in energy certification of buildings.
The analysis conducted shows how varied the situation regarding energy certification in each country is in terms of implementation and scope of application and it also reveals that most countries are still at a halfway stage towards achieving excellence.
