G-21 Background databases in LCA studies
Aspect G-21 Background databases in LCA studies Description According to the ILCD Handbook, the background system comprises those processes that are not under the direct control or decisive influence of the producer of the good. For attributional modelling these are typically processes for both the upstream and downstream parts of the entire life cycle of…

G-22 (Buildings) / G-23 (Products) Data quality
Aspect G-22 (Buildings) / G-23 (Products) Data quality Description Generally speaking, the data quality in LCA refers to the relevance of generic or specific LCA data in accordance with the goal and scope of the study. Depending on the background data sources (literature, industry data), and the boundaries and context of the study (e.g. for…

G-23 Choice of LCI/LCIA datasets for screening LCA
Aspect G-23 Choice of LCI/LCIA datasets for screening LCA Description Different LCI/LCA data are needed to assess the environmental impacts of buildings. They make it possible to quantify the different impacts related to the building products and equipment, the construction site, the operational energy and water uses, and the deconstruction of the building. Depending on…

G-24 Choice of LCI/LCIA datasets for simplified LCA
Aspect G-24 Choice of LCI/LCIA datasets for simplified LCA Description Different LCI/LCIA data are needed to assess the environmental impacts of buildings. They make it possible to quantify the different impacts related to the building products and equipment, the construction site, the operational energy and water uses, and the deconstruction of the building. Depending on…

G-25 Choice of LCI/LCIA-datasets for complete LCA
Aspect G-25 Choice of LCI/LCIA-datasets for complete LCA Description Different LCI/LCIA data are needed to assess the environmental impacts of buildings. They make it possible to quantify the different impacts related to the building products and equipment, the construction site, the operational energy and water uses, and the deconstruction of the building. Depending on the…

G-26 Use of building physical description data
Aspect G-26 Use of building physical description data Description The type, the format, the level of detail and the quality of building-related data depend on the time of assessment (e.g. concept stage, basic design stage, detailed design stage, as built), on the objective of the study, and on the building’s stakeholders. Which kind of data…

G-27 (Buildings) / G-25 (Products) Choice of environmental indicators – screening and simplified LCA
Aspect G-27 (Buildings) / G-25 (Products) Choice of environmental indicators – screening and simplified LCA Description The choice of a set of environmental indicators should always try to avoid pollution transfer. Currently, a large number of indicators can be found in the LCA literature. They fall into different: selected LCI indicators, midpoint life cycle impact…

G-29 (Buildings) / G-27 (Products) Abiotic resources depletion indicator
Aspect G-29 (Buildings) / G-27 (Products) Abiotic resources depletion indicator Description In LCA, different indicators can be used for assessing the use of resources. These can be based on a thermodynamic approach (use of energy or exergy indicators), on a mass flow approach (use of a total mass requirement indicator), on a surplus of energy…
