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

René van Gijlswijk


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?

External cladding kit (ECK) Fibreline GFRP

Suspended Ceiling kit (SCK) Fibre gypsum lamella

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?

Complete life-cycle assessment and life-cycle cost assessment

• Life span

• Maintenance

• Demolition and recycling or disposal

Best estimate of impact of full scale manufacturing by extrapolation

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

Do we meet the

target?

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.
