Cross-cutting challenges discussed:

• Low awareness among homeowners and practitioners of DBLs
• Difficulty demonstrating clear monetary value
• GDPR and data-sharing roadblocks
• Fragmented interoperability solutions
• Lack of standardised terminology across DBLs

Ways forward:

• Aligning with economic and social policy priorities (e.g. affordable housing)
• Incentivising usage with clear stakeholder value
• Building cross-border, interoperable data architectures
