IEA EBC Annex 72 Assessing life cycle related environmental impacts caused by buildings

The project IEA EBC Annex 72 Assessing life cycle related environmental impacts caused by buildings will focus on the assessment of the primary energy demand, greenhouse gas emissions and environmental impacts of buildings during the buildings life cycle. The purpose of the project is to reach consensus on the assessment of the methodology, which yet allows to respecting national and regional traditions regarding data and modelling in order to work towards the definition of national and regional benchmarks. The development of benchmarks is done by collecting a comprehensive amount of case studies for analysis. Furthermore in order to integrate this knowledge into the design process, the purpose is to better link methods for the environmental assessment with methods and tools used during the design and planning process and to support the participating member countries in developing national or regional LCA databases. Finally to agree on recommendations for national and international standardization work related to life cycle thinking applied on buildings (e.g. energy performance of buildings directive).

In addition to the above, the purpose of the Danish participation in the project, is to contribute with knowledge in order to support the formulation of expected future requirements to buildings life cycle environmental impacts in Demark, to improve the LCA tools, data and methods used in Denmark in order to prepare the Danish building sector for the requirements expected in near future.
