The nZEB-strategies of ZEBRA2020 were based on its market tracking, which built on data from the European construction sector, energy performance certificates, nZEB best-practice and scenarios. The strategy was developed and communicated via bi-directional national and international policies and industry workshops and made accessible via an online “nZEB-tracker” based on the projects results and building-databases.

ZEBRA 2020 Data tool enables to display indicators on the status of European building stock development in 4 main sections: new construction, renovation activities, sales of energy efficient equipment and energy performance certificates (EPC) .

ZEBRA 2020 nZEB Tracker

Image module

The nZEB tracker focuses on dynamic market aspects and uses data from the Data Tool to create nZEB-tracking graphs for each country and the EU as a whole to measure the status of the market maturity for nearly Zero-Energy Buildings (nZEB) in the European Union.

This tool shows scenarios of the market transition to nZEB and analyses how the current building standars and policy settings affect the building stock transition to nZEB until 2050 and how more ambitious policies could change this transition.

A nearly Zero-Energy Building (nZEB) is a building with a very high energy performance. The nearly zero or very low amount of energy required should be covered to a very significant extent by energy from renewable sources, including energy produced on-site or nearby.

A sustainable European society and economy will be based on renewable energy and high resource efficiency. For the housing sector, this implies the large scale deployment of low-energy buildings (so called nearly Zero-Energy Buildings). Indeed, the European legislation (Energy Performance of Buildings Directive, EPBD) makes nZEBs a standard by 2020. The technology is already available and proven; however, the large-scale uptake of nZEB construction and renovation will be a big challenge for all market actors and stakeholders involved. To start with, there is a substantial gap in reliable data on current market activities. This makes it difficult for policy makers to evaluate the success of their policies and measures.

The European Union and Member States have defined specific and ambitious targets for the transition towards nZEBs. A number of measures and policy instruments have already been implemented. However, additional activities and a clear strategy are needed to achieve these targets by 2020 and beyond. Such a strategy has to be defined and continuously adapted according to the monitoring results of the transition towards nZEBs. Thus, there is a need for a well-based, comprehensive database of current market activities and an assessment of the gap between real market activities on one hand and the targets on the other hand.

ZEBRA2020 covered seventeen European countries and almost 90% of the European building stock (EU & EEA). These countries have different climatic conditions, polices and economic capabilities.


This project has received funding from the Intelligent Energy Europe program of the European commission.
