This report describes the work conducted to analyse the current state of data storage systems for each of the partners participating in the TIMEPAC project that own EPC data representing six countries and regions of Europe: Austria (Land Salzburg), Croatia, Cyprus, Italy (Piemonte), Slovenia, and Spain (Catalonia). A methodology based on a survey has been developed to collect and compare the current state of the EPC databases facilitated by each partner. The surveys were carried out using a data collection form structure, enabling comparison between countries.
An audit based on a list of key metrics (which include openness, performance, origin, flexibility to changes, number of users, etc.) and characteristics (technologies, connectivity, etc.) has been completed to identify limitations and deficiencies of current EPC data storage systems. The metrics calculation for the six audited EPC databases highlighted important differences between them. The main ones refer to the interlinking of the EPC database with external sources like cadastre and to the level of access to EPC data granted to citizens and third parties.
From the result of the audit, it can be concluded that some EPC databases still do not provide citizens and third parties with access to their data. One of the main obstacles seems to be the conflicts with privacy and data protection laws. Furthermore, two EPC databases, namely those from Croatia and Cyprus, could potentially run automated procedures to upload data to a database management system. Finally, only a few EPC databases include monitoring data on the household energy consumption required for the Building Rehabilitation Passport.
