INDUSTRIAL BUILDING LIFE CYCLE ASSESSMENT (LCA)
CASE STUDY USING THREE DIFFERENT LCA SOFTWARE TOOLS
JOHANNA MERO, RAMBOLL FINLAND OY 31.5.2016 - WBC16 - TAMPERE HALL
BACKGROUND
- In the EU, buildings and the construction sector account for:
- 42 % of final energy consumption
- 35 % of GHG emissions
- 50 % of extracted raw materials
- 30 % of overall water consumption
- Legislation and regulation is becoming stricter and the industry is also developing voluntary actions and initiatives to tackle these problems.
- Awareness of industry actors is rising simultaneously with demand from the clients’ side
Life Cycle Assessment (LCA) is a tool that
helps quantifying the environmental impacts
over the whole building life cycle
Only the
measurable is
manageable
The results can be
used to support
decision making
throughout the
project
1. Quantify the environmental life cycle impacts of an industrial building.
2. See how the results settle in line with existing LCA results obtained for residential and office buildings.
3. Find out whether the results differ when calculated using three different LCA software tools.
4. Interview industry actors to form an understanding of building LCA markets.
RESEARCH QUESTIONS & GOALS

LCA PROCESS (SIMPLIFIED)
1. Construction material bill of quantities (BIM)
2. Assumptions and best estimates:
• Transportation distances, maintenance & EOL scenarios…
3. Modelling of product system in LCA software tools
Embodied life cycle impacts
4. Energy simulations
Operational energy use
5. Emission factors

• Industrial building LCA results in line with previous research
• Commercial LCA software tools developed for industry use are able to produce results that are comparable to building LCA results obtained in scientific research
• Tool selection doesn’t seem to significantly affect the results
CONCLUSIONS

WHY LCA?
- To steer building design towards solution with lower environmental impacts
- Quality assurance
- Marketing and communication opportunities
- Way to separate from competitors
- To gain points in environmental certification schemes:
- LEEDv4 New Construction – MRc Building life-cycle impact reduction (3-4 p)
- BREEAM International 2016 New Construction – Mat01 Life cycle impacts (1-6 p)
- DGNB, HQE…
- Monetary benefits
