Evaluation at building level Construction products
=
Intermediate products
Construction products
≠
Finished products
Product performance only assessed at the building level

Why component level is misleading ?
Can only be assessed at the building level
Example : 1m² external wall with fixed U value and external finishing
Different

Life cycle assessment building level
More impacts
- Material production
Less impacts
- Building use: energy, water use, maintenance, …
More thermal
mass ?
Simple vs.
triple glazing ?
More
insulation ?
Can only be assessed on the whole life cycle,
the material production can not be assessed separately
More
systems ?

DESIGN & STUDY
• Data from structural, energetic, … simulations
Plans, measurements
• Structure
• Internal walls
• Systems…
Calculation tool
• Input from EPD database

Building life cycle assessment : how to go forward in
Belgium?
• To be done by producers : LCA based on EN15804
• Set-up d-Base in collaboration with SPF/FOD & others
Product database (EPD)
• EN 15978
• Scenarios for Belgian market to be validated by stakeholders group
Building calculation rules and scenarios
• Linked with d-Bases
• Compatible with design tools & software Building calculation
tool
• Benchmark for each indicator
• Thresholds and scaling system to be integrated
Rating system
