Foreword When Annex 57 launched in preparation phase, in EBC’s strategic plan for 2007-2012, it was said “LCA methods still need a great amount of research and international collaboration”. The evaluation of energy consumption and related GHG emissions resulting from the use of buildings is becoming more accurate and is being applied in the design of more energy efficient building envelopes, systems and regulations. This means that the weight of the energy consumption and GHG emissions as well as GHG emission due to fluorocarbon gases caused by stages other than the use of the buildings is becoming larger, and their estimation methods will be more important in the future. It can be said that it is the time to further study the scientific basis of embodied energy and GHG emissions for building construction and new Annex 57 with international team was organized in IEA-EBC. Embodied energy and GHG due to building construction and civil engineering account for 20% of the entire energy consumption and GHG in the world. The embodied GHG emissions due to construction industries are approximately 5 to 10% of the entire energy consumption in developed countries and 10 to 30% in developing countries. Though the rates greatly vary depending on the country and region, the reduction of embodied energy and GHG emissions may have a tremendous effect on the reduction of global energy consumption and GHG emissions. Annex 57 research reveals the actual situation of embodied energy and GHG emissions as well as surveys their calculation methods and theoretical background. The methods and effects of reducing embodied energy and GHG emissions are shown through case studies. Outcomes of the Annex research are compiled and finalized in a Project report and various guidelines in order to help practitioners, policy makers and other stakeholders deepen their understanding, through which a broader use of buildings with less embodied energy and GHG emissions is encouraged. This report summarizes the different subtask reports in the Project report and the conclusions of the Annex 57 work.
