The Annex 72 focuses on the assessment of the primary energy demand, greenhouse gas emissions and environmental impacts of buildings during production, construction, operation and dismantling, i.e. during the entire life cycle of buildings. The purpose of Annex 72 is: - to reach consensus on the assessment methodology, which yet allows respecting national or regional situations and rules regarding data and modeling. - to better link methods for the environmental assessment with procedures and tools used during the design process (i.e. building information modeling, BIM) - to work towards the definition of national and regional benchmarks and target values regarding primary energy demand, greenhouse gas emissions and environmental impacts of buildings during their full life cycle, including binding values for operational and embodied carbon. - to support participating countries in need in the task of developing national or regional life cycle assessment databases tailored to the building and real estate sector - to agree on recommendations for national and international standardization work related to life cycle thinking applied on buildings (e.g. draft for energy performance of buildings directive (European Commission 2021) The scope of Annex 72 covers dwellings (single and multiple family housings), office buildings and possibly school buildings, both new and existing buildings. The life cycle covers the stages production (production of construction materials, building components and technical systems including resource extraction), construction process (erection of the building), use (operational energy and water use, maintenance, repair and replacement, planned refurbishment), as well as end of life (de-construction, recycling/waste processing and disposal). The indicators addressed comprise primary energy demand (non-renewable and renewable), greenhouse gas emissions (energy- and non-energy related) as well as environmental impacts.
