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

The Annex will focus on the assessment of the primary energy demand, greenhouse gas emissions and environmental impacts of buildings during production, construction, use and end of life (dismantling), i.e. during the entire life cycle of buildings. The purpose of the Annex is (1) to reach consensus on the assessment methodology, which yet allows to respecting national or regional traditions regarding data and modelling; (2) to better link methods for the environmental assessment with methods and tools used during the design and planning process(i.e. building information modelling, BIM); (3) to work towards the definition of national and regional benchmarks regarding primary energy demand, greenhouse gas emissions and environmental impacts of buildings during their full life cycle; (4) to support participating member countries in need in the task of developing national or regional life cycle assessment databases tailored to the building sector; (5) to agree on recommendations for national and international standardisation work related to life cycle thinking applied on buildings.
