THE STUDENT TOOLKIT
Introduction
The following activities are intended for students to use either in their product
study or in their major coursework. The activities should help them to assess
the environmental, social and economic sustainability, either of existing
products or of their own different design ideas.
The Ecodesign Web and the Design Abacus are both qualitative
methods of analysis, useful for identifying areas where a product
or a design could be improved in terms of sustainability.
The Eco-indicator is more detailed, and involves some qualitative
analysis.
A method of using footprint analysis in major coursework will
be added at a later date.
ST1: ECODESIGN WEB
ACTIVITY PURPOSE
To enable students to assess the environmental performance of a current product
and outline the targets for redesign.
SUITABILITY FOR A/S and A2 STUDENTS
This activity can be used with both AS and A2 level students.
WHEN TO USE THE ACTIVITY
The Ecodesign Web is useful at various points in AS and A2 work. During product
analysis it can be used to rate an existing product or an alternative design.
During planning a major product it can be used to identify problem areas
in sustainability for your design ideas.
IS IT FOR GROUPS OR INDIVIDUALS?
It can be used with a small group or a whole class working in groups or individually.
SUSTAINABILITY ISSUES CONSIDERED
The activity aims to focus on how the redesign of a product can improve its
environmental sustainability.
ASSESSMENT CRITIERIA
This will help identify the particular part of the product that is in need
of improvement. This is a qualitative tool which is not precise but instead
gives an indication of the areas where there are concerns. At both AS and
A2 level it would help in criteria A1, A2, C1, C2 and T1. At A2 it meets
D3 precisely.
THE ACTIVITY AND HINTS ON HOW TO ORGANISE IT
• Students can work individually or in small groups to assess a product.
• It is often useful to have two of each product to be assessed. Ask the
students to dismantle one before the start of the activity as they may need to
investigate what the different components are made from etc.
• Each individual or group needs an Ecodesign Web to complete.
• To assess the product the student (or group) should go to each part of
the web in turn and decide how good or bad the current product is in that area.
This is just a relative measure and accuracy is not needed.
• Once the result is assigned for each area of the web the points can be
joined and the area inside the points shaded to give a picture of the product’s
performance (for completed example see p xxx).
• Students should then discuss which areas to focus on when redesigning
the product to make it more sustainable.
• The targets for the redesign can then be drawn on the web and the area
shaded in a different colour.
OTHER WAYS OF USING THE ECODESIGN WEB
• As described above the web is used to assess an existing product for
redesign.
• It is equally useful in helping students identify aspects of a product
that are very good in terms of sustainability and which they could therefore
include in their own design. For example, if a product is shown to be very good
in terms of its ease of disassembly, the student might wish to incorporate that
idea into his/her own design. The student might take another good feature from
another product.
• Students can also assess their own design ideas using the Ecodesign Web.
If they complete an assessment when they have generated their early ideas, they
can modify their design in the light of the assessment before going on to make
their product.

ST2: DESIGN ABACUS
ACTIVITY PURPOSE
To enable students to assess the sustainability performance of a current product
or a design idea, highlight the areas where further research is needed and
outline the targets for redesign.
SUITABILITY FOR AS and A2 STUDENTS
This activity can be used with both AS and A2 level students.
WHEN TO USE THE ACTIVITY
The Design Abacus is useful at various points in AS and A2 work. During product
analysis it can be used to rate an existing product or an alternative design.
During planning a major product it can be used to identify problem areas
in sustainability for your design ideas.
IS IT FOR GROUPS OR INDIVIDUALS?
It can be used with a small group or a whole class working in groups or individually.
SUSTAINABILITY ISSUES CONSIDERED
The activity can be tailored to meet your own requirements at the time you
use it. You can use only environmental, only social or only economic aspects
of sustainability or all three. Teachers or students can identify the issues
that they feel are most important to consider. All values issues can be assessed
using the abacus. However, if a student wishes to concentrate on one values
aspect only, e.g. environmental issues, that is equally acceptable.
ASSESSMENT CRITERIA
This will help identify the particular part of the product that is most/least
sustainable and in need of improvement. This is a qualitative tool that is
not meant to be precise but instead gives an indication of areas for concern.
At both AS and A2 level it would help in criteria A1, A2, C1, C2 and T1.
At A2 it meets D3 precisely.
THE ACTIVITY AND HINTS ON HOW TO ORGANISE IT
• Students can work individually or in groups to assess the product.
• It is often useful to have two of each product to be assessed. Ask the
student to dismantle one before the start of the activity as they may need to
investigate what the different materials are etc.
• Each individual or group needs a number of blank abacus sheets.
• Decide whether to consider environmental, social or economic issues first.
Write the relevant title in the bottom box on the abacus sheet (see example of
completed sheets).
• Identify a number of issues which are important for the particular product
(for help in identifying issues see p xxx). Decide which ones you are to assess.
• Write each of the issues to be assessed onto the appropriate abacus sheet.
The ideal condition is listed at the top and the worst condition at the bottom,
for example, in the focal area of end of life the ideal condition is easy to
disassemble and the worst case is difficult to disassemble.
• When all issues have been transferred on to the abacus sheets the assessment
can begin.
• To assess the product the student (or group) should take each issue in
turn and decide how good or bad the current product is in that area. This is
just a relative measure and accuracy is not needed.
• Once the score is assigned for a particular issue the students can then
consider the confidence level. The aim of this is to indicate how confident they
are in their judgement. If the students are unsure about anything they can give
a low confidence rating and this will help highlight those areas where further
research about the product is needed.
• The students should continue assessing the product for each sustainability
heading until all issues have been considered.
• The individual sheets can then be joined together and a line drawn to
connect all the scores in the issues area and confidence levels.
• This assessment then gives a very visual result that highlights the good
and bad areas of the product.
• The targets for the redesign can then be drawn on the abacus in a different
colour and when the redesign is compete it can be assessed against the target
to see if it has been met.
OTHER WAYS OF USING THE DESIGN ABACUS
• It can also be used to compare two products. Simply use different coloured
pen or pencil for each product assessed. This might help students identify good
aspects of different products that they can then include in their own designs.
•It can be used to compare two different design ideas they have come up
with themselves. They should be able to identify which is the more sustainable.
• Instead of using the three issues of sustainability separately, some
students have found it useful to use the abacus to identify sustainability issues
over a product’s life cycle. So, instead of using the title environmental
in the bottom box, they may start with material selection, then move on to production,
distribution, use and end of life.

ST3: THE ECO-INDICATOR
ACTIVITY PURPOSE
Eco-indicators provide a simple process to allow students to calculate the
environmental and social impacts of products and services. It can be used
on existing products or services or when analysing potential new designs,
or when comparing one or more products.
SUITABILITY FOR AS and A2 STUDENTS
This sophisticated activity is designed for A2 students to perform in-depth
analysis of products and systems.
WHEN TO USE THE ACTIVITY
The Eco-indicator can be a valuable tool at many stages of A2 work. It can
be used at the product analysis stage to highlight problem areas or during
project work to compare designs or pinpoint areas for improvement. It can
also be used to quantify the successes and improvements of design outcomes.
IS IT FOR GROUPS OR INDIVIDUALS?
There are a lot of stages to this tool so it lends itself to being introduced
to students as a class that then splits into groups of four or five to carry
out the tasks involved. Some assistance may be required for the mathematical
calculations involved. Students can then use it on their own during their
A2 project work if they wish.
SUSTAINABILITY ISSUES CONSIDERED
This activity considers environmental and social issues as it takes into account
human health, ecosystem quality and use of resources. The impact that different
stages of the life-cycle have on social and environmental factors is highlighted
as the Eco-indicator is divided into production, use and disposal. An extra
discussion can also be made about the influence of values during the development
of the Eco-indicator values.
ASSESSMENT CRITERIA
The activity meets A2 - D3 precisely.
THE ACTIVITY AND HINTS ON HOW TO ORGANISE IT
• The Eco-indicator is a table listing the material or
process, the amount, the Eco-indicator value and the eco-points
for each aspect of the life-cycle. It is split into three sections:
Production Raw materials (e.g. polystyrene), Processing and
manufacture (e.g. injection moulding)
Use Transportation of the product (e.g. shipping), Energy required during use
(e.g. electricity), Consumables required for use (e.g. paper)
Disposal
• The first stage of the Eco-indicator is to produce
a list of component parts. Ask the students to disassemble the
product, identify the materials and processes that make each
part, and find the weight (in kgs) of each part. Discussions
can also be made as to how easy the product is to disassemble
and the implications of this for recycling.
• Give each student a copy of the table found below and
ask them to add each element to the correct section.
• The product elements are each quantified in relevant
units (raw materials in kgs, electricity in kWh, shipping in
tkm etc) and these figures can be filled in on the table.
Eco-indicator values are numbers assigned to every material
and process used by designers and can be found in a series of
tables available from the Pre website (http://www.pre.nl) in
the ‘Manual for Designers’. The Eco-indicator value
indicates a material’s or an action’s impact based
on its effects on:
Human health (e.g. mercury would score many points)
Ecosystem quality (e.g. anything with a toxic by-product scores many points)
Resources (e.g. use of renewable resources scores few points)
• Ask the student to find out the Eco-indicator value
for each of the product elements. They can then multiply the
weight of each of the product elements by its Eco-indicator
value to give its eco-points. The higher the points, the worse
the environmental impact of that element.
• The total number of eco-points can then be calculated
for each life-cycle stage and graphs can be drawn.
• Students can then discuss which elements and stages
of the products life-cycle cause most impact and can be focused
on during redesign activities.
