tunES brings together 7 national Energy Agencies, representing 132 million citizens, who will tackle the common challenge of making building energy efficiency and smartness instruments work. Member States (MS) receive technical assistance, support and consulting from 4 research organisations, forming the Technical Support Team (TST).

tunES will impact positively on the shortcomings of implementing EPC, SRI, and linked instruments, by structuring work into five building blocks to better collect, share, implement and replicate good practice: Understanding EPC, Upgrading EPC, Databases & Tools, SRI Development & Deployment, and, as horizontal block, Integration of Instruments to maximise harmonisation, coherence and synergies. Each building block is represented by MS Leaders having implemented good practice. MS Followers design policy options, packages and pathways that will facilitate uptake of good practice.

tunES deploys a Technical Support and Assistance Framework based on the EU Better Regulation Guidelines (BRG). For each stage of the policy design process (inception, data collection, analysis, policy options design, prioritisation, impact assessment, iteration, roll-out planning and throughout stakeholder engagement). Simultaneously and across the building blocks, the TST prepares for the Energy Agencies the necessary methods and tools to safeguard consistency within and across MS. From the beginning, results on good practice as well as how to apply BRG methods are publicly shared in a guidance. Other MS are invited to apply all or selective methods in-sync with the project.

The core outcome are seven national policy measure packages including extensively vetted policy options, with clear impact, stakeholder reaction, and concise actions for realising full national implementations. On the EU-level, a comprehensive guidance strategy allows other stakeholders not only to access use cases but have all tools readily at hand for effective replication.
