This result-oriented report presents the main findings and lessons learnt of IEE NeZeR-project.


The NeZeR project (2014-2017) promoted smart and integrated NZEB renovation measures in the European renovation market. The goal of this report is also to guide other countries to utilize the work done in IEE NeZeR by sharing best practices, results and lessons learned during the project.


Based on the work and results of IEE NeZeR-project, the project group has developed the NeZeR-concept. It is a comprehensive and co-creative procedure to promote country-specific implementation of Nearly Zero-Energy Building Renovation (NZEBR).


NeZeR-concept utilizes the NZEBR criteria, developed in NeZeR-project for four European Climatic Zones (North, East, Centre and South). The feasibility of NZEBR over traditional renovation is emphasized by feasibility studies and LCA, LCC and CBA calculations. Also appropriate fiscal incentives for the country are studied. NZEBR city action plans are constructed using the concrete guidelines developed in NeZeR-project. Stakeholder roadmaps include general descriptions of how to achieve mainstream NZEBR and utilization of RES from the perspectives of the different stakeholder groups: barriers, actions, impacts and indicators. Knowledge in the whole building chain with respect to NZEBR concepts is improved through design competitions. The results are disseminated efficiently.
