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-22 Data selection for a product LCA
Aspect G-22 Data selection for a product LCA Description Various data sources exist for the calculation of product LCA data. They differ for example in terms of specificity, age, completeness and certainty. What data requirements apply for the production of product LCA data? related study objective ☒ stand-alone LCA ☒ comparative assertion related study phase…

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-28 (Buildings) / G-26 (Products) Choice of environmental indicators – Complete LCA
Aspect G-28 (Buildings) / G-26 (Products) Choice of environmental indicators – Complete 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 refer to different types of indicator: selected LCI indicators, midpoint life cycle…

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…

G-30 (Buildings) / G-28 (Products) Land use indicator
Aspect G-30 (Buildings) / G-28 (Products) Land use indicator Description Land-use change is linked to human activities such as the exploitation of land for agricultural, industrial, residential, recreational, or other purposes. Currently, several LCIA methods exist, providing both midpoint and endpoint characterization factors. According to the ILCD Handbook, the midpoint characterization factor for land use,…

G-31 (Buildings) / G-29 (Products) Biodiversity indicator
Aspect G-31 (Buildings) / G-29 (Products) Biodiversity indicator Description The loss of species and their diversity caused by destruction of their habitat has become one of the pivotal topics of environmental political actions in recent years. For years the scientific community has been working on completing a portfolio of considered environmental impacts, including taking biodiversity…

G-32 (Buildings) / G-30 (Products) Human toxicity and ecotoxicity indicators
Aspect G-32 (Buildings) / G-30 (Products) Human toxicity and ecotoxicity indicators Description LCIA methodologies usually include midpoint or endpoint indicators for three area of protection: resources, human health and ecosystem. For the two last areas of protection, different indicators are currently available to assess the ecotoxicity and toxicity effects related to a product or a…
