Within the European Union, buildings are currently responsible for 40% of all energy consumption and 36% of total CO2 emissions. The energy demands in our homes, workplaces and leisure facilities consume more energy than either transport or industry, and account for two thirds of energy used by EU buildings. Improving the energy performance of buildings is a cost-effective way of tackling climate change, improving future energy security and meeting EU emissions targets.The 2002 “Energy Performance of Buildings Directive” was adopted into national legislation by all member states in 2006, ensuring that building standards will place a much greater emphasis on minimising energy consumption. The creation of a common methodology for calculating the energy performance of buildings (taking account of local climactic conditions and technical aspects) has been discussed and applied throughout the EU. In 2010 an updated framework of the Directive was adopted, strengthening the energy performance requirements aiming to reduce the carbon footprint of public buildings to an energy standard of nearly zero by 2018, and for this to be extended to all buildings by 2020. It is expected that this will reduce the overall EU energy consumption by 5-6%, resulting in a 5% drop in emissions.To achieve the necessary improvement in energy performance to meet the targets a portfolio of solutions is required; many of which are currently available or are being developed through the adoption of new technologies. There is also an important role to be played by member states in terms of defining minimum standards and, at the EU level, a comprehensive and robust framework needs to be integrated into policy to facilitate sustainable urban development.This timely International Symposium analyses the existing targets, standards and methodologies and seeks to initiate a new dialogue towards achieving greener buildings, more sustainable urban development, boosting economic growth and jobs and fostering better social inclusion and equality.The Centre for Parliamentary Studies welcomes the participation of all key partners, responsible authorities and stakeholders. The Symposium will support the exchange of ideas and encourage delegates to engage in thought-provoking topical debate, providing input and recommendations to the decision makers at EU level.
