LCA
Practice
Scope:
- Building process
- Research
Need:
- Material/Energy inputs
- Their impact per unit
Database:
- Ecoinvent (pay)
- ELCD (free)
- Swedish Life Cycle Center
- Ilmari
EPDs:
- 3rd part certificate
- voluntary
-
Product's life cycle
GENERAL:
- Resources
- Material processing
- Manufacturing
- Distribution
- Use/Maintenance
- End of life
BUILDING:
- Raw material extraction
- Manufacturing
- Construction
(from here: surface parameter)
- Operation (need:
water/electricity generation)
LCA process
CONs:
- Uncertain
- Can be costly
- Not consumption
- Hardly objective
PROs:
- Known
- Flexible
- System perspective
- No problem shifting
Procedure (law)
- Goal
- Focus the work
- Target audience
- Functional unit
- System boundaries
- Inventory (major phase)
- Material
- Environmental data
- Impact
- Global Warming Potential
- Acidification P
- Ozone Depletion
- Eutrophication
- Abiotic Depletion P
- Photochemical
Characterisation factor:
- H equivalent -> Acidification
- CO2 eq ->
Key aspects

usually over-simplied
pre-fabrication is good?
(transport, errors, nrg efficiency)
