Mission
TNO connects people and knowledge
to create innovations that boost the
sustainable competitiveness of
industry and well-being of society.
We do this by:
Consultancy
Contract research
Testing and certification
Licences
Performing statutory assignments

TNO in BioBuild
Leader of environmental and
economic analysis
Establishing a benchmark:
traditional building products
Quick scan environmental
impact and costs during
development
Final assessment: do the
BioBuild products meet em-
bodied energy & costs targets?
Environmental and economic
analysis
is done in cooperation with all the
other
partners in BioBuild.

Environmental assessment in BioBuild

Use biocomposite materials
to reduce embodied energy in:
• building facade
• internal partition wall
• external wall panel
• suspended ceiling
by at least 50% over current materials with no increase in cost.
Approach: three steps
1. Benchmark = setting the reference point
2. Quickscan = to support decisions during development
3. Final assessment = evaluating the developed product

Step 1 – benchmark
What is the environmental performance of current building products?

Step 2 – quickscan
Aim is to provide environmentally relevant information:
1. To support decision making
2. To generate recommendations for development
3. To monitor progress towards final goals

Quickscan in practice: feedback from engineers and finetuning
Results have been presented to the engineers and designers every 3
months; just ahead of the decision making schedule in the project
Results have been presented with meta-information: choices and
assumptions with large influence, in particular with high uncertainty
>> show the effect; feedback from the engineers

Step 3 – final assessment
Goal: final ‘verdict’ of BioBuild products: how do they measure up
against benchmarks for costs and environment? Can we meet 50%
embodied energy reduction at no additional cost?

Summary
In BioBuild, we monitor the environmental performance of our
products during development.
Main target: reduction of 50% of embodied energy compared to non-
biobased products.
For some cases we are already on target, for some we are not yet.
Results have an uncertainty. We continuously work on improving the
reliability during the project to clearly indicate BioBuild advantages at
the end of the project.

Scope of embodied energy in this study
Included:
Non-renewable energy consumption in production phase (in e.g.
agriculture, mining, materials processing, panel manufacturing)
Non-renewable energy consumption (and benefits) of end-of-life
treatment
Chemical energy in non-biobased materials and compounds
Excluded:
The use of renewable energy (biofuels, wind, sun, hydro)
Chemical energy in biobased materials

Quickscan methodology step 3: design
A tool has been developed
to feed the panel design process
with environmental information.
It consists of:
1. Environmental data for processes
BioBuild (BioBuild materials, processing, panel manufacturing, maintenance, end-of-life)
Traditional (materials, processing, panel manufacturing, maintenance, end-of-life)
2. Data link with 3D design tool
Materials
Volumes
Surface areas
3. Definition of cases
4. Calculation for life cycle
Once the design has been adapted, it takes 5 minutes to recalculate
the environmental performance.
