This example comes from the Estonian national study conducted by an Eu-Repair project partner, highlighting one of its case studies. The 19th-century wooden apartment building at F. R. Kreutzwaldi 2 demonstrates how climate goals and heritage protection can be carefully aligned in a smaller Estonian town. The renovation aims to achieve Class B energy performance and reduce carbon emissions by 25%, while respecting the building’s historic character.

The house was insulated externally, with carefully developed detailing to preserve the original façade proportions and architectural relationships. Together with restored wooden windows, upgraded technical systems, district heating, heat-recovery ventilation, and rooftop solar panels, the project demonstrates how thoughtful design and interdisciplinary collaboration can enable meaningful energy improvements in historic buildings.
