G-06 (Buildings) / G-07 (Products) Functional equivalent
Aspect G-06 (Buildings) / G-07 (Products) Functional equivalent Description According to [EN 15643-1], the functional equivalent is a representation of the required and quantified functional and/or technical requirement for a building or an assembled system (part of works), which is used as a basis for comparison. Usually, assessments of individual objects form part of the…

G-35 (Buildings) / G-33 (Products) Normalization of indicators
Aspect G-35 (Buildings) / G-33 (Products) Normalization of indicators Description According to the ILCD Handbook, the normalization step refers to the expression of indicators (LCIA, midpoints or endpoints) relative to a common reference by dividing the indicator results by the respective reference value. Different normalization factors can be applied in practice to help the interpretation…

G-36 (Buildings) / G-34 (Products) Weighting of indicators
Aspect G-36 (Buildings) / G-34 (Products) Weighting of indicators Description According to the ILCD Handbook, the weighting step refers to an optional step of the ISO 14044 standard to support the interpretation of the profile as a fully aggregated result. Generally speaking, it is a subsequent step to the normalization of indicators (see aspect ‘normalization’),…

G-37 (Buildings) / G-35 (Products) Uncertainty analysis for comparative assertion
Aspect G-37 (Buildings) / G-35 (Products) Uncertainty analysis for comparative assertion Description An uncertainty analysis measures the variability of the data values: for example, a low variance leads to a high precision. Because of the long supply chain of building products and buildings as a whole, uncertainties are aggregated over the life cycle. Following [Huijbregts…

G-38 (Buildings) / G-36 (Products) Sensitivity analysis
Aspect G-38 (Buildings) / G-36 (Products) Sensitivity analysis Description According to the ILCD Handbook, the goal of a sensitivity analysis is to assess the reliability of the study by adjusting the main parameters to see how this affects the final results. It is part of the interpretation step, and is generally used together with complementary…
