The Energy Performance of Buildings Directive
The aim of the Directive is to greatly enhance the awareness of energy use in buidings and it is intended to lead to substantial increases in investments in energy efficiency measures within these buildings.
Directive 2002/91/EC of the European Parliament and Council, on the energy performance of buildings, was originally agreed in Brussels in December 2002 coming into force on 4th January 2003. Legislation was required to be in place by 4th January 2006, and affects all buildings, both domestic and non-domestic.
The following gives an overview of the Diective:
Why was the directive introduced?
Increased energy efficiency constitutes an important part of the package of policies and measures needed to comply with the Kyoto Protocol and this Directive is intended to contribute towards achieving this.
The 160 million dwellings in the European Union use over 40% of Europe's energgy and create over 40% of its carbon dioxide emmissions, and that proportion is increasing.
How is this energy used?
Heating fuel is by far the most important component with some 57% of domestic consumption being attributed to haeting fuel and around 25% accounted for by water heating.
How much of this energy can be saved?
According to the European energy commissioner, a cost effective savings potential of around 22% of present consumption can be realised by 2010.
How much can this directive reduce the threat of climate change?
According to the European climte change programme, the directive could deliver uo to 45 million tonnes of carbon dioxide reduction by 2010. In order to meet the agreed Kyoto targets, the European Union must implement reductions of 330 million tonnes between 1990 and 2010.
The Directive sets general principles providing for a system of energy performance requirements and whilst the objectives are established at EU level the detailed implementation is left to member states. The Directive confines itself to the minimum required in order to achieve those objectives and does not go beyond what is necessary for that purpose.
It will look to:
- Implement a regualr inspection and re evaluation regime
- Introduce agreed measurements of realtive energy performance
- Require higher standards for upgrading energy performance
- Improve standards for new buildings.
The Directive is divided into 15 main articles and the following gives an overview of each one:
Article 1: - Objective
The objective is to promote the improvement of energy performance of buildings by requiring:
- a methodology to calculate the integrated energy performance of buildings
- mimimum energy requirements for new buildings
- minimum energy requirements for large existing buildings being renovated
- energy certification of buildings
- regular inspection of boilers and air conditioning systems.
