ABSTRACT
ABSTRACT The IEA EBC Annex 72 focuses 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 IEA EBC Annex 72 is to reach consensus on the assessment methodology, which yet allows to respecting national or regional traditions regarding data and modelling; 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); 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; to support participating member countries in need in the task of developing national or regional life cycle assessment databases tailored to the building sector; and to agree on recommendations for national and international standardisation work related to life cycle thinking applied on buildings (e.g. energy performance of buildings directive (European Commission 2010).
