The European research project "EULEB - European high quality Low Energy Buildings" intends to provide information about good examples of energy efficient buildings in use, in order to reduce prejudices and lack of knowledge of many key actors in the building market. Therefore, a multilingual CD and website was produced, containing detailed information about 25 buildings from all over Europe including measured data about energy consumptions, construction costs, comfort and user acceptance. 150 000 copies of the CD resulting from this work have been disseminated in the beginning of 2007 through European magazines reaching the target groups of architects and engineers as well as investors and property developers all over Europe. Furthermore, all information is available on the project website. The project was performed by a European consortium of five Universities and a European umbrella organisation and it was partly funded by the Intelligent Energy - Europe programme.
