• Eurima Eurima Eurima Eurima is the European Insulation European Insulation European Insulation European Insulation ManufacturersManufacturersManufacturersManufacturers Association Association Association Association and represents the interests of all major mineral wool producers throughout Europe, including companies such as Knauf Insulation, Rockwool, Saint Gobain-Isover, Ursa Insulation, Paroc.
• Members of EurimaEurimaEurimaEurima operate in Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Hungary, Ireland, Italy, Lithuania, Netherlands, Norway, Poland, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.
• In manufacturing mineral wool, members of EurimaEurimaEurimaEurima help to achieve important social and environmental goals: saving energy, minimising pollution, combating noise, reducing the risk of fire and creating European jobs.
• EurimaEurimaEurimaEurima represents 20,000 employees in Europe and the installation of mineral wool keeps many more Europeans at work.

• 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

U-value optimum for heating and cooling demand
– Criteria: cost effectiveness
• Energy price: WEO 2006 – Peak Price
• Investment costs
• Interest rate
• Energy mix
– Criteria: Post Kyoto target

• 100 cities
• Investments versus annual running costs– Interest rate Service lifetime 30 years
• Impact factors– Energy prices: WEO 2006 (IEA scenario) & Peak Price (=US$70 fixed);
fuel mix, incremental costs for 1cm insulation/component

• 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.
