Scenario results for target countries and EU


This tool provides the results of alternative scenarios of development of the building stock and its energy demand in the EU-28 (+ Serbia) up to 2030. Different set of national policy packages on the refurbishment of the existing building stock have been developed in close cooperation with national stakeholders and policy makers. The scenarios are country specific and cannot be compared among countries. The scenarios have been simulated with the Invert/EE-Lab model taking into account the cost of the various renovation options and decision criteria of different groups of investors.


The scenario results for nine target countries and the EU-28 are available at following link:

nZEB Open Days

24. 10. 2013

nZEB Doors Open Days Campaign

NZEB Open Doors Days are organised in Belgium, Germany, Austria, Sweden, Ireland, Hungary, France, Malta, Slovenia, Poland in fall 2013 and 2014. You can visit more than 900 state of the art exemplary buildings and get non-commercial hands-on-experience with nearly zero energy buildings – sharing living, working and building experiences of the owners and builders.

The NZEB Open Doors Days campaign wants to give hands-on-experience with nearly zero energy buildings (NZEB) to the broad public and public authorities and to convince them the EPBD (European Energy Performance Directive) challenge can be met.

The central idea of a Doors Open Day is that visitors will get non-commercial hands-on-experience with nearly zero energy buildings.

eceee Summer Study

13. 06. 2013

Rethink • Renew • Restart

eceee 2013 Summer Study on energy efficiency, 3–8 June 2013

Club Belambra Les Criques, Presqu’île de Giens, Toulon-Hyères, France


The new European Energy Efficiency Directive is a good first step for Europe. But it is just the start. It is time to rethink policies and options. It is time to renew commitments to climate, energy security and reduced energy demand. And it is time to restart activities that actually achieve something. Join us in June to discuss how to make this a reality!


Here you can find an article from the eceee Graffiti about the ENTRANZE side-event


ENTRANZE team joined this event as well:


Innovative policy sets for nZEB

31. 05. 2013

In many countries transforming the building sector is one of the key elements for moving the energy system towards low carbon. Very long reinvestment cycles, large capital intensity and a rather heterogeneous ownership structure make this transformation a challenge for governments to identify policy paths that comply with the long-term targets.


This report provides a comprehensive list of different instrument options all of which are targeting at modernisation measures in the building sector thus addressing the multiple and often target-group specific barriers in the built environment.


Report that provides an overview and assessment of principle integrated policy sets that aim at the nZEB standard is available in Publications/Innovative policy sets for nZEB.

Workshop in Romania held

Acceptance of nZEB report

09. 04. 2013

New report on specific features of public and social acceptance and perception of nearly zero-energy buildings and renewable heating and cooling in Europe with a specific focus on the target countries has been published.


This report explores the factors influencing public acceptance of nearly-zero energy building solutions and renewable heating and cooling in the building sector. It contributes to the ENTRANZE project. ENTRANZE is funded by the Intelligent Energy Europe programme and aims to actively support policy making by providing data, analysis and guidelines to achieve a fast and strong penetration of nearly-zero-energy buildings (nZEB) and renewable heating and cooling (RESH/C) in the existing building stock.


The report is available in section Publications/Acceptance of nZEB.


Workshop in Romania

This workshop will bring evidence based support for policy making and bring together high level representatives from the European Commission, the Romanian Ministry for Regional Development and Public Administration, from local authorities, associations from the construction sector, energy auditors, and experts from the Czech Republic, Poland and Romania.

Please find enclosed our agenda with further details. Please confirm your attendance to the workshop by sending an email to by the 2nd of April.

Data Mapping Tool launched

21. 03. 2013

User-friendly online Data Mapping Tool has been launched. The tool provides in-depth analysis of the structure and dynamics of buildings and related energy systems in EU-27 (+ Croatia and Serbia).  At its core, it’s a statistical tool designed for policy makers and experts in need of hard data for evidence based policy making.

This interface enables users to acquire a comprehensive understanding of the building stock according to thermal quality, use, size, age, type, ownership structure, heating and cooling systems in place and related energy demand by end-use.
