The ENPER-EXIST project was initiated and coordinated by Centre Scientifique et Technique du Bati-ment (CSTB) within the framework of the Intelligent Energy Europe (IEE) programme. ENPER-EXIST involved partners from seven countries (Belgium, Denmark, France, Germany, Greece, The Netherlands, and United Kingdom) on the topic of energy performance standardisation and regulation. One objective of the project was to provide information on the level of building stock knowledge and to collect available data on a broad basis. A second objective was to analyse how this information is being used to make decisions on energy improvements and a third objective was to make recommendations on how to improve the building stock knowledge by using certification schemes. This paper presents the main results of this part of the project (Thomsen et. al., 2007). Energy certification, as proclaimed in the European Energy Performance Building Directive (EPBD, 2002), offers a unique opportunity for improving knowledge about the building stock. Improved knowledge will make it possible to map the energy efficiency of buildings. In addition, it will provide a basis for benchmarking and for calculating energy saving potentials. Moreover, such information will be an important instrument for political decision-making. The EPBD offers freedom of choice regarding the method of certifying the energy performance. The individual member state's decision on energy certification may therefore range from simple meter readings to detailed energy audits. However, this decision determines what knowledge it is possibly to extract afterwards, and for what purpose this knowledge can be used. When deciding on the standards of energy certificates, three elements are crucial for the outcome: the character of the data input, the procedure of certification and the form of quality control. Based on the energy certification schemes existing in Denmark since 1997, this paper contribute with knowledge about the relationship between data, procedure and quality control on one hand, and knowledge that can be extracted on the other. Of special interest is the possi- bility of extracting data about potential energy saving measures distributed on segments of buildings. Such data can be of great importance for finding methods to overcome human and technical barriers to energy savings in buildings.
