2. What did we want?
An interactive online platform:
• Database repository and management (quantitative data and textual
information):
 Country Comparison Dashboard
 Country Profiles/country fact sheets
 Information on key legislation – Time lines & information
 Link to other data/information available on the web
• Data presentation and visualisation
• Data collection through online surveys

3. BPIE Data Portal
The Data Hub for Building Performance in Europe
Objectives:
• The BPIE Data Hub to be the first point of contact for anyone interested
in energy performance in European buildings;
• Provide a multi-source and up to date fact and figures
(i.e. statistics; policy information) on building stock across Europe;
• Allow a smart and user-customisable data search, comparison,
interactive visualization and cost-free download;
• Enable monitoring of EU policy implementation at Member State level;
• Continuous quality improvement and new data generation
through data exchange projects and research partnerships.
