The importance of European historic buildings in achieving climate goals is a central topic in the world and in Europe in light of the Energy Directive, and this is also the main topic of the open seminar to be held on December 4. Speakers from Europe will present the experiences of different countries in achieving climate goals for historic buildings, including examples from Great Britain, Ireland, Belgium, and Estonia. We will present the results of the ICOMOS EPBD working group on European experience in implementing the Energy Efficiency Directive. Climate and heritage guidance material is being compiled within the framework of the Estonian Heritage Homes project. We will discuss the guidance materials for historic buildings prepared by this project and the preparation of a heritage charter. The seminar, which will be held with the participation of well-known European experts, is a good opportunity for international cooperation on heritage and climate issues in Estonia. We invite all those involved in historic buildings to participate and contribute to the discussion. The seminar will be held in a hybrid format. The working language of the seminar is English, with simultaneous interpretation in Estonian.
