The coming years will see a sharp increase in the market uptake of highly efficient buildings supplied by renewable energy throughout Europe: by 2020, all new buildings must be "nearly zero energy buildings" (new public buildings already by 2018). According to the European Buildings Directive, a "nearly zero energy building" (NZEB) is a building with a very high energy performance and whose very low amount of required energy is covered to a very significant extent by energy from renewable sources.

The European Nearly Zero Energy Buildings Conference 2015 offers:  


  • the latest technology trends and financing solutions
  • presentations of standards for NZEBs and how they can be met technically and economically
  • the meeting place for the global sustainable buildings community
  • discussions on optimal levels of energy efficiency and renewable energy sources
  • an outlook on the developments of European and global markets for sustainable buildings, including National Plans for NZEB
  • inspirational case studies of new buildings and renovations and site visits
  • exchange of experience among experts and new business opportunities
  • Young Researchers’ Conference - a conference for young researchers on energy efficiency in buildings
  • a major tradeshow, the "Energiesparmesse", dedicated to energy efficiency and renewable energy in buildings, with 1,600 exhibitors

The World Sustainable Energy Days 2015

The conference is an integrated part of the World Sustainable Energy Days, one of Europe’s largest conferences on energy efficiency and renewable energy. The event is organised by the OÖ Energiesparverband, the energy agency of Upper Austria. Upper Austria is an ideal location for such a conference: due to consistent policies, today there are more than 1,000 buildings meeting passive building standard and several thousand "Nearly Zero Energy Buildings".

In addition to the NZEB Conference, the World Sustainable Energy Days 2015 offer a number of other high-profile events including the "European Pellet Conference", the "Energy Efficiency Watch Conference", the "Energy-Efficient Commercial Buildings Conference", the  Young Researchers’ Conference, poster presentations and technical site visits. In 2014, the event attracted more than 750 participants from 59 countries.
