aims at improving the knowledge about the building stock’s energy performance.
constitutes a data structure for exchanging information regarding the energy performance of buildings.
intends to stimulate large-scale monitoring activities using Energy Performance Certificates as a data source.

The DATAMINE Data Structure – a harmonised language for data exchange

Facing the fact that the certification schemes are very different in the European countries the DATAMINE experts found an agreement on:

  • the information from energy certificates which is needed for energy efficiency monitoring in the building sector
  • specific types of expressing this information, especially conventions on the definitions of these quantities

Model Projects for Data Collection from Energy Certificates

In 12 countries Model Projects with different data collection schemes, certificate types and monitoring targets were realised. They illustrate the variety of monitoring tasks in the European countries, the capability of the DATAMINE data structure and the benefit of a common language to be used for cross-country comparison.

DATAMINE Data Analyses: Cross-Country Comparison of Energy Performance Indicators

When building datasets are collected using the harmonised DATAMINE data structure they can be easily compared. This has been proved by a cross-country comparison of the ca. 19,000 datasets collected in the different Model Projects.

Lessons learnt – Perspectives

All in all the DATAMINE data structure has proved to be a suitable approach for EPBD related data comparison and monitoring activities in the building sector on regional, national and European level. Based on the experiences several recommendations were given how to improve the knowledge about the energy efficiency status and on-going refurbishment processes in the European building stock.
