Material flow analysis by Sankey diagram

Component LCA impacts per m² of wall during 60 years

The table describes the reused products, their supply-chain activities and the associated GHG emissions.

Select a set of columns by clicking on the buttons with the '🔍' icon.

Click on the button to show the missing columns' values.

LCA data quality are evaluated in terms of degree of confidence in their representativeness and appropriateness. Data quality is rated with colored dots:

• Very good : project-specific & product-specific data

• Good : data is a good estimate but may come from a different project or product

• Average : data is an expert jugement or hypothesis based on partial knowledge of the reality

• Poor : data is generic, default data from external source or hypothesis

• Unavailable : no LCA data is used or available, hence calculation is not performed

Material mass analysis graph shows the mass shares of material groups and products in the total mass of the building.

Hover with the pointer and click on the materials groups and products to show their respective mass share (%).

Building LCA impacts are show in the table for each KBOB's impact indicators:

The columns are the building life cycle modules according to EN 15804 and EN 15978.

Select the unit of the LCA impacts expressed either by sqm ERA of building or by sqm ERA of building and by year of building's lifetime (60 years)

This graph shows the impact per kg of product of the selected LCA indicator for the reused products (left) and their new equivalent production (right). New materials effectively used in the building are not shown.

Interact with the graph by clicking on the labels in the legend (i.e. A1-A3, A4, B4, C1-C4) and by zooming on the desired portion of the graph.
