In 2005 the European Commission launched the GreenBuilding Programme (GBP). GreenBuilding is a voluntary programme aiming at improving the energy efficiency of non-residential buildings in Europe on voluntary basis. The programme addresses owners of non-residential buildings to realise cost-effective measures which enhance the energy efficiency of their buildings in one or more technical services. The programme covers both existing and new buildings. The GreenBuilding Programme reached its 8th year of activity and has now achieved its original target of collecting data from over 1000 buildings. The Joint Research Centre (JRC) has therefore decided to close down the GreenBuilding Programme by 1st of October 2014.JRC.F.7-Renewables and Energy Efficienc
