The primary objective of this study is to evaluate possible ventilation solutions for nZEB multi apartment buildings in three European geoclusters. Geo-cluster concept illustrates trans-national areas where strong similarities are found in terms of climate, culture, construction typologies and other factors. Paper presents comparison of ventilation needs for the same case study building located in Denmark, Estonia, Latvia and Portugal. The economic and technical comparison of different ventilation systems are presented as well. Special focus is attended to develop introduction of modular solutions and integration of ventilation ducts into external insulation as this can serve as a complex solution including both external constructions and engineering networks. Presented modular solution includes prefabricated insulation panels with integrated ventilation ducts. This paper is prepared in scope of work done within EU HORIZON2020 MORE-CONNECT project. Research methodology is based on data analysis provided by project partners as well as practical calculation. Compilation of ventilation air volume requirements according to the local regulations for Latvia, Estonia, Portugal and Denmark has shown significant difference in design air change rate in project countries. The financial analysis reveals the price difference between various ventilation strategies and provides discussion topic regarding ventilation strategies in nZEB buildings.
