9 Aspects concerning Module D – Benefits and loads beyond the system boundary
This chapter addresses aspects that are related to life cycle stage D. All the aspects of this chapter provide provisions, rules and guidance for the goal and scope definition and the inventory analysis steps according to [ISO 14040] and [ISO 14044]. Module D makes it possible to quantify the reuse, recovery and recycling potential of…

10 Discussions and perspectives
In this chapter some of the findings of the project are discussed, connections to other research projects are made, and possible future developments of the EeBGuide guidance document are addressed. The original aim of the EeBGuide project was not to develop new provisions or even standards for LCA, but to summarize existing provisions from the…

Annex A: Default Values.
When conducting an LCA study, the practitioner is constantly confronted with figures: some are needed to specify a modelling parameter; others are needed as cross-references, or benchmarks for comparison purposes. Such numbers always depend on the context of a study, and are generally not globally valid, which is why this guidance does not specify the…

Reference Study Period: Buildings.
Following a simplified understanding of a building’s life cycle, the reference study period can be seen as the timespan of use, i.e. the duration of services within Module B. Hence the reference study period has a significant impact on the use stage’s contribution to the life cycle impacts. This means that the reference study period…

Annex B: Reference values for LCA indicators for buildings
For referencing purposes, typical LCA results may be helpful. These values are typically heavily dependent on the assumptions made, and on the various rules that have been applied to a study. Hence a comparison with such values has to be made with special care. Germany: DGNB In Germany, the DGNB building labelling system defines benchmarks…

Annex C: List of available references for life cycle impact assessment indicators chosen in EN 15804/EN 15978
This Annex provides the practitioner with the sources of recommended LCIA methods (when they are in agreement with the EN 15804/EN 15978 standards). It also highlights the current inconsistencies between the units of the ILCD-recommended LCIA methods and the units of the EN 15804/EN 15978 standards. The practitioner should notice that while different impact assessment…
