Long-term renovation strategies are a requirement of the Energy Performance of Buildings Directive (EPBD) for all member states. BPIE and national Green Building Councils for the H2020 project Build Upon2 published 8 factsheets discussing the initiatives of long-term renovation strategies of 8 countries (Croatia, Hungary, Ireland, Italy, Poland, Spain, Turkey and the UK).

The case studies identify which levels of governance must cooperate during the design and implementation of long-term renovation strategies. They also highlight the status quo of the process, successes and challenges faced at local and national level.

Here a summary for each country concerning the main challenges for the implementation of LTRS:

• Croatia: lack of communication channels between local authorities and national government; lack of financial resources and qualified staff to implement renovation strategies
• Hungary: involvement of as many stakeholders as possible at all levels; insufficient awareness about the multiple benefits of building renovations
• Ireland: limited resources to conduct a large-scale, comprehensive consultation process for the LTRS; lack of a coherent strategy
• Italy: contribution and impact of local actions to overall national strategies and objectives is hard to assess
• Poland: the process for drafting the LTRS and providing input is not clear; insufficient awareness about the multiple benefits of building renovations
• Spain: lack of continuity in preparation and implementation of LTRS; lack of coordination between national, regional and municipal governance levels
• Turkey: lack of involvement of stakeholders during the design/implementation policies and measures; insufficient information on current building stock and energy use; financial mechanism should be developed
• The UK: lack of connection across governance levels; lack of strategic coordination, central leadership, coordination and funding.
