G-13 (Buildings) / G-12 (Products) Infrastructure machinery and capital equipment for material production, energy, water, waste and transport for screening and simplified LCA
Aspect G-13 (Buildings) / G-12 (Products) Infrastructure machinery and capital equipment for material production, energy, water, waste and transport for screening and simplified LCA Description Different LCA databases and datasets with different boundaries are available. These databases apply different rules for including or excluding infrastructure in LCA datasets (e.g. owing to database policy or cut-off-rules).…

G-14 (Buildings) / G-13 (Products) Infrastructure machinery and capital equipment for material production, energy, water, waste and transport for complete LCA.
Aspect G-14 (Buildings) / G-13 (Products) Infrastructure machinery and capital equipment for material production, energy, water, waste and transport for complete LCA. Description Various LCA databases and datasets with different boundaries are available. These databases apply different rules on the inclusion or exclusion of infrastructure in LCA datasets (e.g. owing to database policy or cut-off-rules).…

G-15 (Buildings) / G-14 (Products) Transport of goods in LCA studies
Aspect G-15 (Buildings) / G-14 (Products) Transport of goods in LCA studies Description With globalized supply chains, logistic processes occur throughout the life cycle of every product. The most important ones are transport processes, where several possibilities exist for the activity of carrying goods (e.g. by truck, ship or airplane) for the various life cycle…

G-16 (Buildings) / G-15 (Products) Accounting for carbon storage/carbon sequestration
Aspect G-16 (Buildings) / G-15 (Products) Accounting for carbon storage/carbon sequestration Description Some products (e.g. wooden products) take up atmospheric carbon dioxide while producing biomass. Concrete- and lime-based products can also take up atmospheric carbon dioxide through recarbonization during the use phase . By using these materials or products, this fixed CO2 is stored during…

G- 18 Allocation case for cement-based materials
Aspect G- 18 Allocation case for cement-based materials Description Increasing numbers of building products are being made of secondary raw materials (SRM), or of generated waste that can be recycled throughout their life cycle. On the one hand, recycling eliminates the need to use virgin raw materials. On the other hand, the new commercial interest…

G-18 (Buildings) / G-16 (Products) Allocation
Aspect G-18 (Buildings) / G-16 (Products) Allocation Description Normally, LCA studies should focus only on a single product at a time. However, systems under assessment often produce more than one product. The same problem arises when different waste flows are treated collectively in the same process (e.g. incineration). In these situations, the allocation problem arises:…

G-19 Allocation examples for wooden products
Aspect G-19 Allocation examples for wooden products Description Increasing numbers of building products are being made of secondary raw materials (SRM), or of generated waste that can be recycled throughout their life cycle. On the one hand, recycling eliminates the need to use virgin raw materials. On the other hand, the new commercial interest in…

G-20 Define reference building
Aspect G-20 Define reference building Description The whole-life performance of nearly all building products can be assessed only in the context of a specific building. Is it possible to set a reference building for this comparison? related study objective ☒ stand-alone LCA ☒ comparative assertion related study phase ☒ ☐ ☐ ☐ ☐ goal and…

G-20 (Buildings) / G-17 (Products) Allocation case: reuse, recycling and recovery
Aspect G-20 (Buildings) / G-17 (Products) Allocation case: reuse, recycling and recovery Description When the lifespan of a product ends, it can be reused, recycled, or used for recovery in another product system. These recovery operations entail a benefit for the system that yielded them. How to allocate these benefits to the system under study,…

G-24 Collecting foreground and background data for product LCA
Aspect G-24 Collecting foreground and background data for product LCA Description Different data need to be collected for a product LCA study. The most important data collection is usually the production stage especially for highly complex manufacturing processes. The data can be based on industry or companies involved in the project else on secondary sources…
