Europäische Ansätze für Energieeffizienz-Monitoring auf der Basis von Energieausweis-Daten

European attempt at energy performance monitoring based on data collections and certification schemes

The launch of the DATAMINE project has been driven by the need for concrete data on the actual energy performance of the European building stock as well as the potential energy savings and CO₂ reductions. In the longer term data can help develop tailored, cost-efficient complementary measures to energy performance legislation, such as soft loans and tax incentives. DATAMINE aims to construct a knowledge base using the information on the energy performance certificates issued when buildings are constructed, sold or rented. In the framework of DATAMINE test projects were carried out on large samples of buildings in 12 countries, each with individual monitoring targets. In each country the same data structure was used for data collection which had been developed at the forefront. Full allowance is made for the Europe-wide differences in certification schemes, since each country has a scheme tailored to its specific needs, building stock and climate. Around 19,000 datasets have been collected in the common DATAMINE format. Cross-country analysis of the collected data was performed comparing different energy performance indicators. The result of the evaluation activities gives a clearer insight into the current state of refurbishment of specific building subsets in each country. Finally conclusions were drawn regarding the development of monitoring systems in each country and on EU level.
