• Eurima does scientific research on energy efficiency in buildings to contribute to the European debate on behalf of the members.

• Eurima is active at EU level to advocate the benefits of energy efficiency in buildings and make it work!

• Eurima also works with national associations in most European countries.

2. The energy efficiency potential

in buildings in Europe

"the most sustainable energy is saved energy"

1st: minimise energy loss

3rd: efficient use of fossil energy sources

2nd: use renewable energy sources

– Criteria: cost effectiveness

• Energy price: WEO 2006 – Peak Price

• Investment costs

• Interest rate

• Comparison with existing U-values requirements in EU 27 confirms how much cash is being wasted.

• National and regional standards are far below what is necessary.

• We invite member states to analyze U-value requirements

• The recommendations are based on cost efficiency

and climate targets.

• Results should be understood as the minimum

recommendations from EU.

• It is the responsibility of each country to optimize the

implementation taking into account other factors:

� regional climate conditions, heated floor/wall,

condensation risks, etc.
