IEA SHC Task 47: Position Paper

By: IEA SHC Task 47
The IEA’s Energy Technology Perspectives 2008 report shows that buildings are responsible for about 45% of the total energy consumption in OECD countries and 38% globally. More than half of the existing building stock will be standing in 2050 and more than 50% of the buildings in many OECD countries were built before 1970. The EU Parliament approved in April 2009 a recommendation that member states have to set intermediate goals for existing buildings as a fixed minimum percentage of buildings to be net zero energy by 2015 and 2020. This also includes the existing non-residential buildings, and a dramatic reduction in primary energy consumption will be needed.
