5.2 Goal and scope
According to the ILCD Handbook, aspects relating to goal definition should be addressed first. The ILCD Handbook set out to identify the purpose of the different types of assessment in the building sector, and the target audience (architects, building designers, construction companies etc.). In total, four aspects have been identified: the issue of comparative assertions,…

G-01 Goal definition for building and product LCA
Aspect G-01 Goal definition for building and product LCA Description According to ISO 14040-44 and the ILCD Handbook, the goal definition of a study is a key LCA requirement, as it guides all the detailed aspects of the scope definition, which then determine the LCI and LCIA provisions. Special attention should be paid to this…

G-02 Classifying the decision context as situation A, B, and C for building and product LCA
Aspect G-02 Classifying the decision context as situation A, B, and C for building and product LCA Description The ILCD Handbook distinguishes between different decision contexts for LCA studies. This distinction is part of the goal and scope definition of an LCA study, and has major implications for further definitions of system boundaries and modelling…

G-03 Future technical developments and innovation
Aspect G-03 Future technical developments and innovation Description This aspect includes the possibility of considering the effects of future developments with regard to technologies, materials and end-of-life options (e.g. scenarios on energy recovery, or recycling) within a building LCA. In the current business world, technologies and production techniques are changing rapidly. In contrast, building and…

G-04 Comparative assertion for building or product LCA
Aspect G-04 Comparative assertion for building or product LCA Description Comparative assertion is an environmental claim regarding the superiority or equivalence of one building product (or one building design) compared with a competing building product (or an alternative building design) that performs the same function. Usually, the comparison of alternative products, systems or buildings is…

G-05 Scope definition for building and product LCA
Aspect G-05 Scope definition for building and product LCA Description According to [ISO 14040], [ISO 14044], and the ILCD Handbook, the scope definition of a study is the step where the main requirements related to methodology, quality, reporting and review in accordance with the goal of the study (i.e. based on the reasons for the…

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-06 Distinction between the declared unit and the functional unit
Aspect G-06 Distinction between the declared unit and the functional unit Description The functional unit represents the quantified performance of a product system for use as a reference unit for the LCA study. It is the unit of scale or reference on which the LCA results are based, and relates to the given function of…

G-07 (Buildings) / G-08 (Products) Functional equivalent vs. functional unit vs. declared unit
Aspect G-07 (Buildings) / G-08 (Products) Functional equivalent vs. functional unit vs. declared unit Description ISO 14040, ISO 14044 and EN 15804 define a functional unit; EN 15804 also defines a declared unit. EN 15978 defines a functional equivalent.What are the differences, and when should which term be used? Related study objective ☒ stand-alone LCA…
