Rezumat/Abstract. Quite similar large-panel prefabrication technologies were used for residential buildings in East-Europe and some countries in Northern-Europe, e.g. Finland. Even if technologically similar, the fate of the building stocks is different in the two regions, with buildings functioning sustainably in Finland. Hence, one could adapt the maintenance and renovation experiences to the building stock in other countries, creating opportunities for communities and business. The paper presents technological, economical, and institutional/policy aspects in the two environments, and discusses them in the larger framework of European sustainability targets. For major renovation, as targeted in the paper, methods of change management should be applied, entailing thoughtful planning and sensitive implementation and above all, consultation/involvement of the people affected. If the presented interventions would be used in a systematic and planned way, improvements can be achieved for social sustainability targets like e.g. adaptability and visual comfort, while maintaining the safety and security. Finally, the limitations of the approach in light of the institutional setting and ownership structure are discussed, highlighting how different ownership models are favoring or hindering major retrofit interventions. The paper offers ways on strengthening the role of key stakeholders to support major renovation interventions on the panel building stock.
