Introduction to the activity (teacher): 

Provide the stimulus to motivate the students by considering the dilemma: How do we provide affordable housing whilst minimising heating requirement? There are not enough homes in the UK for everyone who needs one. Some of the houses we do have are expensive to run, poorly maintained and cost a fortune in rent. How do we get the housing builders to provide enough affordable, cheap to run housing for the population? 

One possible solution is adopting Passivhaus standards. The Passivhaus is a building that conforms to a standard around heating requirements that ensures the insulation (U value) of the building material, including doors, windows and floors, prevents heat leaving the building so that a minimum heating requirement is needed. If all houses conformed to Passivhaus standards, the running costs for the householder would be reduced. 

 

Teaching schedule: 

Provide stimulus by highlighting the housing crisis in the UK:  

Students can then research and find the answers to the following questions using the following links, or other websites: 

 

Housing crisis in the UK: 

 

Students can work in groups to work on the extent of the problem from the bullet points provided. This activity can be used to develop design skills (Define the problem) 

 

1. Get the engineering knowledge about preventing heat leaving a house:

If you can prevent heat leaving, you won’t need to add any more, it will stay at the same temperature. Related engineering concepts are:   

 

2. Task:

a. Start with a standard footprint of a three-bed semi, from local estate agents. Make some assumptions about inside and outside temperatures, height of ceilings and any other values that may be needed.

b. Use the U value table to calculate the heat loss for this house (in Watts). The excel table has been pre-populated or you can do this as a group

  1. With uninsulated materials (single glazing, empty cavity wall, no loft insulation. 
  2. With standard insulation (double glazing, loft insulation, cavity wall insulation. 
  3. If Passivhaus standards were used to build the house. 

 c. Costs

  1. Find the typical cost for heating per kWh
  2. Compare the costs for replacing the heat lost.

 d. Final synoptic activity

  1. Passivhaus costs a lot more than standard new build. How do housebuilders afford it?
  2. Provide examples of the cost of building a Passivhaus standard building materials and reduced heating bills.
  3. Suggest some ‘carrots’ and ‘sticks’ that could be used to make sure housing in the UK is affordable to rent/buy and run.

 

3. Assessment:

The spreadsheet can be assessed, and the students could write a report giving facts and figures comparing different levels of insulation and the effects on running costs.

Learning and teaching notes: 

The purpose of this exercise is to encourage students to think in a socio-technical perspective of delivering extreme low carbon housing (e.g. Passivhaus), in order to support the occupants in adapting to new technologies and low-carbon lifestyle, shifting the paradigm from building isolated energy efficient homes to forming low-carbon communities.

Terminology: 

Before beginning the activity, teachers and learners will want to become familiar with the following concepts. 

 

Activity overview:  

Students will role-play the post occupancy stage of inhabiting a Passivhaus home by playing different characters with different priorities (and personalities). Students will need to learn what new technologies and features are included in Passivhaus and what difficulties/problems the residents might encounter, and at the same time familiarise themselves with contemporary research on energy behaviour, performance gap, rebound effect, as well as broader issues in decarbonisation transition such as social justice and low carbon community building. Through two community meetings, the community manager needs to resolve the residents’ issues, support the residents in learning and adapting their behaviours, and devising an engagement plan to allow the residents to form a self-governed low-carbon community. 

 

Step one: Preparation prior to class: 

Provide a list of reading materials on ‘performance gap’, ‘rebound effect’, ‘adaptive comfort’, energy behaviour, usability and control literature, as well as on Passivhaus and examples of low-carbon features and technologies involved to get a sense of what difficulties residents might encounter.  

To prepare for the role-play activity, assign students in advance to take on different roles (randomly or purposefully), or let them self-assign based on their interests. They should try to get a sense of their character’s values, lifestyle, priorities, abilities. Where no information is available, students can imagine the experiences and perspectives of the residents. Students assigned to be community managers or building associations will prepare for the role-play by learning about the Passivhaus system and prepare ways to support occupants’ learning and behaviour adaptation. The goal is to come up with an engagement plan, facilitate the residents to form their own community knowledge base and peer support. (Considering 1. Who are you engaging (types of residents and their characteristics); 2. How are you engaging (level of engagement, types of communication; 3. When are you engaging (frequency of engagement) 

 

Step two: In class, starting by giving prompts for discussions: 

Below are several prompts for discussion questions and activities that can be used. Each prompt could take up as little or as much time as the educator wishes, depending on where they want the focus of the discussion to be. 

 

  1. Discuss what support the residents might need in post occupancy stage? Who should provide (/pay for) the support? For how long? Any examples or best practice that they might know? Does support needs to be tailored to specific groups of people? (see extra prompts at the end for potential difficulties)
  2. Discuss what the risks are involved in residents not being sufficiently supported to adapt their behaviour when living in a low-carbon house or Passivhaus? (reflect on literature)
  3. Discuss what are the barriers to domestic behaviour change? What are the barriers to support the residents in changing behaviour and to build low-carbon community? 

 

Step three: Class 1 Role Play  

Prior to the Role Play, consider the following prompts: 

Consider the variety of residents and scenarios:

Their varying demographics, physical and mental abilities, lifestyle and priorities. The following characters are examples. Students can make up their own characters. Students can choose scenarios of  

1) social housing or; 

2) private owner-occupier  

Social housing tenants will likely have a more stretched budget, higher unemployment rate and a bigger proportion of disabled or inactive population. They will have different priorities, knowledge and occupancy patterns than private owner-occupier, and will be further disadvantaged during decarbonisation transition (Zhao, 2023). They will need different strategies and motivations to be engaged. The characters of residents could be chosen from a variety of sources (e.g. RIBA Brief generator), or based on students’ own experiences. Each character needs to introduce themselves in a succinct manner. 

 

Other stakeholders involved include: 

They are role-specific characters that don’t necessarily need a backstory. They are there to listen, take notes, give advice and come up with an engagement plan. 

 

Consider the post occupancy in different stages: 

  1. Prior to move-in 
  2. Move-in day 
  3. The initial month 
  4. Change of season  
  5. Quarterly energy audit meeting 

 

Consider the difficulties the residents might encounter: 

 

Consider the different engagement levels of the residents: 

 

The role-play consists of two community meetings over two classes. The first meeting is held at two weeks after move-in date. The second meeting at 6 months of occupancy. The meeting should include a variety of residents on one side, and the ‘chair’ of the meeting on the other. (Consider the accessibility and inclusivity of the meetings as when and where those will be held). In the first meeting, residents will get to know each other, ask questions about house-related problems occurred in the first two weeks, voice concerns. Community managers/council members will chair the meeting, take notes and make plans for support. The teacher should act as a moderator to guide students through the session. First the teacher will briefly highlight the issue up for discussion, then pass it to the ‘chair’ of the meeting. The ‘chair’ of the meeting will open the meeting with the purpose of the meeting – to support the residents and facilitate a self-governed low carbon community. They then ask the residents to feedback on their experience and difficulties. At the end of the first meeting, the group of students will need to co-design an engagement plan, including setting agendas for the second meeting in a 6-month interval (but in reality will happen in the second class) and share the plan with the residents and the class. The teacher and class will comment on the plan. The group will revise the plan after class so it’s ready for the second meeting. 

 

Step four: Homework tasks: Revising the plan 

The students will use the time before the second class to revise the plan and prepare for challenges, problems occurred over the 6-months period. 

Optional wild cards could be used as unpredictable events occur between the first and second meeting. Such events include: 

 

Step five: Class 2 Role play 

The second meeting in the second class will either be chaired by community managers/council members, or be chaired by a few residents, monitored by community managers/council members. The second meeting begins the same way. The students playing residents should research/imagine problems occurred during the 6 months period (refer to literature), and what elements of the engagement plan devised at the end of the first meeting worked and what hasn’t worked. The ‘chair’ of the meeting will take notes, ask questions or try to steer the conversations. At the end of the second meeting, the ‘chair’ of the meeting will reflect on the support and engagement plan, revise it and make a longer-term plan for the community to self-govern and grow. At the end of this class, the whole class could then engage in a discussion about the outcome of the meetings. Teachers could focus on an analysis of how the process went, a discussion about broader themes of social justice, community building, comfort, lifestyle and value system. Challenge students to consider their personal biases and position at the outset and reflect on those positions and biases at the end of the meeting.

Learning and teaching notes: 

This resource outlines a project brief that requires an engineer to assess the local area to understand the scale of flooding and the local context. This will highlight how climate change affects everyday life, how water usage is changing and happening on our doorstep.

The project also requires the engineer to be considerate of the needs of a local business and showcases how climate change affects the economy and individual lives, enabling some degree of empathy and compassion to this exercise.

Depending upon the level of the students and considering the needs of modules or learning outcomes, the project could follow either or both of the following pathways: 

 

Pathway 1 – Introduction to Electronic Engineering (beginner/intermediate- Level 4) 

In this pathway, the project deliverables could be in the form of a physical artefact, together with a technical specification. 

 

Pathway 2 – Electromagnetics in Engineering (intermediate/advanced- Level 5) 

This project allows teachers the option to stop at multiple points for questions and/or activities as desired.

Overview:  

A local business premises near to a river has been suffering from severe flooding over the last 10 years. The business owner seeks to install a warning system that can provide adequate notice of a possible flood situation. 

 

Time frame & structure:
This project can be completed over 30 hours, either in a block covering 2-3 weeks (preferred) or 1 hour per week over the academic term. This project should be attempted in teams of 3-5 students. This would enable the group to develop a prototype, but the Specification (Pathway 1) and Technical Report (Pathway 2) could be individual submissions without collusion to enable individual assessment.

It is recommended that a genuine premises is found that has had the issues described above and a site visit could be made. This will not only give much needed context to the scenario but will also trigger emotional response and personal ownership to the problem. 

To prepare for activities related to sustainability, teachers may want to read, or assign students to pre-read the following article:
‘Mean or Green: Which values can promote stable pro-environmental behaviour?’ 

 

Context and Stakeholders: 

Flooding in the local town has become more prevalent over recent years, impacting homes and businesses. A local coffee shop priding itself on its ethical credentials is located adjacent to the river and is one of the businesses that has suffered from severe flooding over the last 10 years, causing thousands of pounds worth of spoilt stock and loss of revenue. The local council’s flood warning system is far from adequate to protect individuals on a site-by-site basis. So the shop is looking for an individual warning system, giving the manager and staff adequate notice of a possible flood situation. This will enable stock to be moved in good time to a safer drier location. The shop manager is very conscious of wanting to implement a sustainable design that uses sustainable materials and renewable energy, to promote the values of the shop. It is becoming clear that such a solution would also benefit other businesses that experience flooding and a wider solution should also be considered. 

 

Pathway 1 

This project requires assessment of the local area and ideally a visit to the retailer to understand their needs and consider options for water level monitoring. You are required to consider environmental and sustainable factors when presenting a solution.

After a visit to the premises:  

  1. Discussion: What is your initial reaction to the effects of the flooding and does it surprise you? What might your initial reaction reveal to you about your own perspectives and values?
  2. Discussion: What is your initial reaction to the causes of the flooding and does it surprise you? What might your initial reaction reveal to you about your own perspectives and values?
  3. Discussion and activity: List the potential issues and risks to installing a device in or near to the river bank.
  4. Activity: Research water level monitoring. What are the main technical and logistical issues with this technology in this scenario?
  5. Activity: Both cost-benefit and sustainable trade-off analyses are valuable approaches to consider in this case.  Determine the possible courses of action and undertake both types of analysis for each position by considering both short- and long-term consequences.    
  6. Reflection: Obligations to future generations: Do we have a responsibility to provide a safe and healthy environment for humans that don’t yet exist, or for an ecosystem that will eventually change? 

 

Design Process​:

To satisfy the learning outcomes identified above the following activities are suggested. 

 

Assessment activity 1 – Physical artefact: 

Design, build and test a prototype flood warning device, monitoring various water levels and controlling an output or outputs in an alarm condition to meet the following as a minimum:
 

a) The device will require the use of an analogue sensor that will directly or indirectly output an electrical signal proportional to the water level. 

b) It will integrate to appropriate Operational Amplifier circuitry. 

c) The circuitry will control an output device or devices. 

d) The power consumption of the complete circuit will be assessed to allow an appropriate renewable energy supply to be specified (but not necessarily be part of the build). 

 

Assessment activity 2 – Technical specification: 

The written specification and accompanying drawings shall enable a solution to be manufactured based on the study, evaluation and affirmation of the product requirements. 

The evaluation of the product requirements and consequent component selection will reference the use of design tools and problem-solving techniques. In compiling the specification the component selection and integration will highlight the underlying engineering principles that have been followed. The specification shall be no more than 1000 words (plus illustrations and references). 

 

Pathway 2

This project requires assessment of the local area and ideally a visit to the retailer to understand their needs and consider options for water level monitoring.

You are required to consider environmental and sustainable factors when presenting a solution. 

After a visit to the premises:  

  1. Discussion: What is your initial reaction to the effects of the flooding and does it surprise you? What might your initial reaction reveal to you about your own perspectives and values?
  2. Discussion: What is your initial reaction to the causes of the flooding and does it surprise you? What might your initial reaction reveal to you about your own perspectives and values?
  3. Discussion and activity: List the potential issues and risks to installing a device in or near to the river bank.
  4. Activity: Both cost-benefit and sustainable trade-off analyses are valuable approaches to consider in this case.  Determine the possible courses of action and undertake both types of analysis for each position by considering both short- and long-term consequences.      

 

Wireless communication of information electronically is now commonplace. It’s important for the learners to understand the differences between the various types both technically and commercially to enable the most appropriate form of communication to be chosen.

Pathway 1 above explains the need for a flood warning device to monitor water levels of a river. In Pathway 2, this part of the challenge (which could be achieved in isolation) is to communicate this information from the river to an office location within the town. 

 

Design Process: 

Design a communications system that will transmit data, equivalent to the height of the river in metres. The maximum frequency and distance over which the data can be transmitted should be explored and defined, but as a minimum this data should be sent every 20 seconds over a distance of 500m. 

 

Assessment activity – Technical report:       

A set of user requirements and two possible technical solutions shall be presented in the form of a Technical Report: 

The report shall be no more than 3000 words (plus illustrations and references)

Learning and teaching notes: 

The following are a set of use cases for a maturity model designed to improve energy and resource efficiency in manufacturing facilities. This guide can help engineering educators integrate some of the main concepts behind this model (efficient use of energy and resources in factories in the context of continuous improvement and sustainability) into student learning by showcasing case study examples.   

Teachers could use one or all of the following use cases to put students in the shoes of a practicing engineer whose responsibility is to evaluate and improve factory fitness from a sustainability perspective.

Factory assessment in multiple assembly facilities for an aircraft manufacturer:

The assessment is part of the following use case on this industrial energy efficiency network (IEEN): 

The company operates in the aerospace sector and runs 11 manufacturing sites that employ approximately 50000 people across 4 European countries. Most of the sites are responsible for specific parts of the aircraft i.e. fuselage, wings. These parts once manufactured are sent to two final assembly sites. Addressing energy efficiency in manufacturing has been a major concern for the company for several years.  

 

It was not until 2006 that a corporate policy was developed that would formalize efforts towards energy efficiency and set a 20% reduction in energy by the year 2020 across all manufacturing sites. An environmental steering committee at board level was set up which also oversaw waste reduction and resource efficiency. The year 2006 became the baseline year for energy savings and performance measures. Energy saving projects were initiated then, across multiple manufacturing sites. These were carried out as project-based activities, locally guided by the heads of each division and function per site.  

 

A corporate protocol for developing the business case for each project is an initial part of the process. It is designed to assign particular resources and accountabilities to the people in charge of the improvements. Up to 2012, improvement initiatives had a local focus per site and an awareness-raising character. It was agreed that in order to replicate local improvements across the plants a process of cross-plant coordination was necessary. A study on the barriers to energy efficiency in this company revealed three important barriers which needed to be addressed: 

  • Lack of accountability: The site energy manager is responsible for reducing the site’s energy consumption but only has authority to act within a facility’s domain–that is, by improving facilities and services, such as buildings and switchgear. They are not empowered to act within a manufacturing operations parameter. Therefore, no one is responsible for reducing energy demand.  
  • No clear ownership: Many improvements are identified but then delayed due to a lack of funding to carry out the works. This is because neither facilities nor manufacturing operations agree whether the improvement is inside their parameter: typically, facilities claim that it is a manufacturing process improvement, and operations claim that any benefit would be realized by facilities. Both are correct, hence neither will commit resources to achieve the improvement and own the improvement. 
  • No sense of urgency: A corporate target exists for energy reduction–but the planned date for achieving this is 2020.  

The solution that the environmental steering committee decided to support, was the creation of an industrial energy efficiency network (IEEN). The company had previously done something similar when seeking to harmonize its manufacturing processes through  process technology groups (Lunt et al., 2015). This approach consists of each plant nominating a representative who is taking the lead and coordinating activities. It is expected that the industrial network would contribute to a significant 7% share out of the 20% energy reduction target for the year 2020 since its establishment as an operation in 2012.  

 

The network’s operations are further facilitated with corporate resources such as online tools that help practitioners report and track the progress of current projects, review past ones, and learn about best-available techniques. This practice evolved into an intranet website that is further available to the wider community of practitioners and aims to generate further interest and enhance the flow of information back to the network. Additionally, a handbook to guide new and existing members in engaging effectively with the network and its objective has been developed for wider distribution. These tools are supported by training campaigns across the sites.   

 

Most of the network members also act as boundary spanners (Gittell and Weiss, 2004) in the sense that they have established connections to process technology groups or they are members of these groups as well. This helps the network establish strong links with other informal groups within the organization and act as conductor for a better flow of ideas between these groups and the network. Potentially, network members have a chance to influence core technology groups towards energy efficiency at product level.  

 

On average, a 5-10% work-time allocation is approved for all network members to engage with the network functions. In case a member is not coping in terms of time management there is the option of sub-contracting the improvement project to an external subcontractor who is hired for that particular purpose and the subcontractor’s time allocation to the project can be up to 100%.  

 

 “….by having the network we meet and we select together a list of projects that we want to put forward to access that central pot of money. So we know roughly how much will be allocated to industrial energy efficiency and so we select projects across all of the sites that we think will get funded and we put them all together as a group…so rather than having lots of individual sites making individual requests for funding and being rejected, by going together as a group and having some kind of strategy as well…” 

 

Each dot on each of the model rows represents the relative efficiencies that a factory achieves in saving energy and resources through best practice (5 of 11 factories represented here, each delivering an aircraft part towards final assembly). The assessment allowed this network of energy efficiency engineers and managers to better understand the strengths and weaknesses in different factories and where the learning opportunities exist (and against which dimension of the model). 

 

2. The perception problem in manufacturing processes and management practice:

The following assessment is performed in a leading aerospace company where two senior engineering managers (green and orange lines) find it difficult to agree on the maturity of different practices currently used at the factory level as part of their environmental sustainability strategy.  

This assessment was part of the following use case: 

The self-assessment was completed by the head of environment and one of his associates in the same function. These two practitioners work closely together and are based in the UK headquarters. Even though the maturity profiles do not vary significantly (1 level plus or minus) it is clear that there is very little overall agreement on the maturity levels in each dimension.  

 

3. Using the maturity model as a consensus building tool in a factory:

Seven practitioners from different parts of the business (engineering, operations, marketing, health and safety etc.) were brought together to understand how they think the factory performs. The convergence between perceptions was very small and this would indicate high levels of resistance to change and continuous improvement. For example, if senior managers think they are doing really well, they will not invest time and effort in better practices and technologies. 

A timeline (today +5years) was used to understand where they think they are today and where they want to be tomorrow.  

This can be one of the ways of thinking about improvements that need to occur, starting with areas of interest that are underperforming and developing the right projects to address the gaps.

Learning and teaching notes: 

This case study offers learners an explorative journey through the multifaceted aspects of deploying off-grid renewable solutions, considering practical, ethical, and societal implications. It dwells on themes such as Engineering and Sustainable Development (emphasizing the role of engineering in driving sustainable initiatives) and Engineering Practice (exploring the application of engineering principles in real-world contexts). 

The dilemma in this case is presented in six parts. If desired, a teacher can use Part one in isolation, but Parts two and three develop and complicate the concepts presented in Part one to provide for additional learning. The case study allows teachers the option to stop at multiple points for questions and/or activities, as desired.

In accordance with a report from the International Energy Agency (IEA) and statistics provided by the World Bank, approximately 633 million individuals in Africa currently lack access to electricity. This stark reality has significant implications for the remote villages across the continent, where challenges related to energy access persistently impact various aspects of daily life and stall social and economic development. In response to this critical issue, the deployment of off-grid renewable solutions emerges as a promising and sustainable alternative. Such solutions have the potential to not only address the pressing energy gap but also to catalyse development in isolated regions. 

Situated in one of Egypt’s most breathtaking desert landscapes, Siwa holds a position of immense natural heritage importance within Egypt and on a global scale. The region is home to highly endangered species, some of which have restricted distributions found only in Siwa Oasis. Classified as a remote area, a particular community in Siwa Oasis currently relies predominantly on diesel generators for its power needs, as it remains disconnected from the national grid. Moreover, extending the national grid to this location is deemed economically and environmentally impractical, given the long distances and rugged terrain. 

Despite these challenges, Siwa Oasis possesses abundant renewable resources that can serve as the foundation for implementing a reliable, economical, and sustainable energy source. Recognising the environmental significance of the area, the Egyptian Environmental Affairs Agency (EEAA) declared Siwa Oasis as a protected area in 2002. 

 

Part one: Household energy for Siwa Oasis  

Imagine being an electrical engineer tasked with developing an off-grid, sustainable power solution for Siwa Oasis village. Your goal is to develop a solution that not only addresses the power needs but also is sustainable, ethical, and has a positive impact on the community. The following data may help in developing your solution.   

 

Data on Household Energy for Siwa Oasis:

 

Activities: 

  1. Analyse typical household appliances and their power consumption (lighting, refrigeration, pressing Iron).
  2. Simulate daily energy usage patterns using smart meter data.
  3. Identify peak usage times and propose strategies for energy conservation (example LED bulbs, etc)
  4. Calculate appliance power consumption and estimate electricity costs.
  5. Discussion:  

a. How does this situation relate to SDG 7, and why is it essential for sustainable development? 

b. What are the primary and secondary challenges of implementing off-grid solutions in remote villages? 

 

Part two: Power supply options 

Electricity supply in Siwa Oasis is mainly depends on Diesel Generators, 4 MAN Diesel Generators of 21 MW which are going to be wasted in four years, 2 CAT Diesel Generators of 5.2 MW and 1 MAN Diesel Generator 4 MW for emergency. Compare and contrast various power supply options for the household (renewable vs. fossil fuel). 

 

  1. Renewable: Focus on solar PV systems, including hands-on activities like solar panel power output measurements and battery sizing calculations. 
  2. Fossil fuel: Briefly discuss diesel generators and their environmental impact. 

 

The Siwa Oasis community is divided over the choice of power supply options for their households. On one hand, there is a group advocating for a complete shift to renewable energy, emphasising the environmental benefits and long-term sustainability of solar PV systems. On the other hand, there is a faction arguing to continue relying on the existing diesel generators, citing concerns about the reliability and initial costs associated with solar power. The community must decide which power supply option aligns with their values, priorities, and long-term goals for sustainability and energy independence. This decision will not only impact their day-to-day lives but also shape the future of energy use in Siwa Oasis. 

 

Optional STOP for questions and activities:

  1. Debate: Is it ethical to impose new technologies on communities, even if it’s for perceived improvement of living conditions?
  2. Discussion: How can engineers ensure the sustainability (environmental and operational) of off-grid solutions in remote locations?
  3. Activities: Students to design a basic solar PV system for the household, considering factors like energy demand, solar resource availability, and budget constraints.  

 

Part three: Community mini-grid via harnessing the desert sun 

Mini-grid systems (sometimes referred to as micro-grids) generally serve several buildings or entire communities. The abundant sunshine in Siwa community makes it ideal for solar photovoltaic (PV) systems and based on the load demand of the community, a solar PV mini grid solution will work perfectly. 

Electrical components of a typical PV system can be classified into DC and AC. 

 

DC components: The electrical connection of solar modules to the inverter constitutes the DC part of a PV installation. Its design requires particular care and reliable components, as there is a risk of significant accidents with high DC voltages and currents, especially due to electric arcs.  

The key DC components are:  

 

AC components: The equipment installed on the AC side of the inverter depends on the size and voltage class of the grid connection (low-voltage (LV), medium-voltage (MV), or high-voltage (HV) grid). Utility-scale PV plants usually require the following equipment:

Premise: 

As environmental pressures mount, the world demands not just engineering solutions, but sustainable ones. This shift presents profound challenges and opportunities for engineering educators. How can we equip future engineers with the ethical frameworks and critical thinking skills needed to navigate the complex trade-offs inherent in green solutions? 

This article provides a guide for integrating ethical considerations into engineering education by using case studies. By fostering awareness of sustainability principles and promoting responsible decision-making through real-world examples, we can empower students to become stewards of a more equitable and resilient future. 

 

The interplay of ethics and sustainability: 

At its core, sustainability goes beyond environmental impact. It encompasses social responsibility, economic viability, and intergenerational equity. Ethical engineering aligns with these principles by: 

 

Integrating ethical considerations into engineering curricula presents several challenges: 

 

Learning from a case study:  

The sprawling Ivanpah Solar Electric Generating System in California’s Mojave Desert, initially celebrated as a beacon of clean energy, now casts a complex shadow on the region’s ecological landscape. While harnessing the sun’s power to electrify millions, its concentrated solar technology inadvertently unleashed unintended consequences. The intense heat generated by the mirrors tragically claimed thousands of birds, particularly desert tortoises, a threatened species. Drawn to the shimmering light, they would collide with the mirrors or structures, falling victim to a technological mirage. This stark reality challenged the “green” label of a project originally intended to combat climate change.  

 

Unforeseen costs of progress: 

Ivanpah’s case highlights the hidden costs of even well-intentioned renewable energy projects. It sparks critical questions for students to grapple with: 

Sustainability beyond carbon emissions: While reducing carbon footprint is crucial, broader ecosystem impacts must be considered. Can technological advancements mitigate harm to vulnerable species and habitats? 

Balancing energy needs with ecological needs: How can we find the sweet spot between harnessing renewable energy and preserving biodiversity? Can alternative technologies or site selection minimise ecological disruption? 

Engaging stakeholders in ethical decision-making: How can local communities and ecological experts be meaningfully included in planning and mitigation strategies to ensure equitable outcomes? 

By delving into the Ivanpah case (and others like it*), students can develop critical thinking skills to analyse the long-term implications of seemingly green solutions. They learn to consider diverse perspectives, advocate for responsible design practices, and prioritise environmental stewardship alongside energy production. 

*Relevant case studies: 

 

Empowering future engineers: 

As educators, we hold the power to shape the ethical compass of future engineers. By integrating ethical considerations into the fabric of our curriculum, we can equip them with the tools and knowledge necessary to: 

 

Conclusion: 

The pursuit of a sustainable future demands ethical engineers, engineers who can not only innovate, but also act with integrity and responsibility. By equipping students with the knowledge and skills necessary to grapple with complex ethical dilemmas, we can empower them to become transformative agents of change, shaping a world that thrives for generations to come.

Who is this article for? This article should be read by educators at all levels in higher education who are curious about how maker spaces and communities can contribute to sustainability efforts in engineering education. Engaging with this topic will also help to prepare students with the soft skill sets that employers are looking for. 

 

Premise:  

Makerspaces can play a valuable role in Education for Sustainable Development (ESD). In this article, we highlight three specific contributions they can make to ESD in Engineering: Makerspaces enable engineering in real-world contexts; they build cross-disciplinary connections and inclusive learning; and they promote responsible consumption.   

 

A brief introduction to makerspaces: 

In recent years, a ‘makerspace’ movement has emerged in Higher Education institutions. While most prevalent in the US, there are now a number of university-based makerspaces in the UK, including the iForge at the University of Sheffield, the Institute of Making at UCL, and the Makerspace at King’s College London. So what is a makerspace, and what do they have to do with Education for Sustainable Development (ESD)?  

Makerspaces are part of a larger “maker movement” that includes maker fairs, clubs and magazines. Within universities, they are “facilities and cultures that afford unstructured student-centric environments for design, invention, and prototyping.” (Forest et al., 2016). Successful and inclusive makerspaces are student led. Student ownership of makerspace initiatives deepens student motivation, promotes learning, and encourages peer-to-peer collaboration. Successful makerspaces produce thriving learning communities, through which projects can emerge organically, outside of curriculum structures and discipline boundaries.  

In terms of Education for Sustainable Development (ESD), this means that students can bring their passion to make a difference, and can meet other students with similar interests but complementary skill sets. With support from the University, they can then be given opportunities to put their passion and skills into practice. Below, we focus on three concrete contributions that makerspaces can make to ESD:  Opportunities for applied learning; expanded potential for cross-disciplinary learning, and the chance to deepen engaged learning on sustainable consumption.  

 

1. Maker communities enable engineering in real world contexts:

1.1 ESD rationale 

ESD enables students to think critically about possible solutions to global challenges. It encourages students to consider the social, economic, and political context in which change takes place. ESD also spurs students to engage, where possible, with those beyond the university.  

It may be tempting to think of engineering as simply a technical exercise: one in which scientific and mathematical knowledge is taken and applied to the world around us. In practice, like all other professions, engineers do not simply apply knowledge, they create it. In order to do their work, engineers build, hold, and share ideas about how the world works: how users will behave; how materials will function; how they can be repaired or disposed of; what risks are acceptable, and why. These ideas about what is reasonable, rational, and probable are, in turn, shaped by the broader social, political, and economic context in which they work. This context shapes everything from what data is available, to what projects are prioritised, and how risk assessments are made. Rather than trying to ignore or remove these subjective and context-based elements of engineering, we need to understand them. In other words, rather than ask whether an engineering process is impacted by social, political, and economic factors we need to ask how this impact happens and the consequences that it holds. ESD encourages students to think about these issues.  

 

1.2 The contribution of makerspaces 

The availability of both equipment and expertise, and the potential for practical solutions, means that makerspaces often attract projects from outside the university. These provide opportunities to practise engineering in real-world contexts, where there is the possibility for participatory design. All such projects will require some consideration of social, political, or economic factors, which are at the heart of the Sustainable Development Goals.  

One example of this is SheffHEPP, a hydroelectric power project at the University of Sheffield. In response to requests for help from local communities, students are designing and building small-scale hydroelectric power installations in a number of locations. This multidisciplinary project requires an understanding of water engineering, electrical power generation, battery storage and mechanical power transmission, as well as taking into consideration the legal, financial, and environmental constraints of such an undertaking. But it also requires Making – students have made scale models and tested them in the lab, and are now looking to implement their designs in situ. Such combinations of practical engineering and real-world problems that require consideration of the wider context provide powerful educational experiences that expose students to the realities of sustainable development. 

 

There are a number of national and international organisations for students that promote SDGs through competitions and design challenges. These include: 

 

Student engagement with such activities is growing exponentially, and makerspaces can benefit students who are prototyping ideas for the competitions. At Sheffield, there are over 20 co-curricular student-led projects in engineering, involving around 700 students, many of which engage with the SDGs. In addition to SheffHEPP and teams entering all of the above competitions, these include teams designing solutions for rainwater harvesting, vaccine storage, cyclone-proof shelters for refugees, plastics recycling, and retrofitting buildings to reduce energy consumption. As well as the employability benefits of such activities, students are looking for ways to use engineering to create a better future, with awareness of issues around climate change and sustainability increasing year on year. And none of these activities would be possible without access to maker facilities to build prototypes.  

 

Linked to the makerspace movement is the concept of hackathons – short sprints where teams of students compete to design and prototype the best solution to a challenge. At Sheffield, these have included: 

 

In summary, Makerspaces enable students to access multiple initiatives through which they can engage in learning that is potentially participatory and applied. These forms of learning are critical to ESD and have the potential to address multiple Sustainable Development Goals.  

 

2. Maker communities build cross-disciplinary connections and encourage inclusive learning:

2.1 ESD rationale 

Global complex challenges cannot be resolved by engineers alone. ESD encourages students to value different forms of knowledge, from within and beyond academia. Within academia, makerspaces can provide opportunities for students to collaborate with peers from other disciplines. Cross-disciplinary knowledge can play a crucial role in understanding the complex challenges that face our world today. Makerspaces also offer an opportunity for students to engage with other forms of knowledge – such as the knowledge that is formed through lived experience – and appreciate the role that this plays in effective practices of design and creation. Finally, makerspaces can help students to communicate their knowledge in ways that are understandable to non-specialist audiences. This inclusive approach to knowledge creation and knowledge sharing enables students to think innovatively about sustainable solutions for the future.  

 

2.2 The contribution of makerspaces   

Cross-disciplinary spaces  

Student-led makerspaces encourage students to lead in the creation of cross-disciplinary connections. For example, at the University of Sheffield, the makerspace has primarily been used by engineering students. Currently, however, the students are working hard to create events that will actively draw in students from across the university. This provides students with a co-created space for cross-disciplinary exchange as students train each other on different machines, learning alongside each other in the space. At other times, staff from different disciplines can come together to create shared opportunities for learning. 

The cross-disciplinary nature of makerspaces and the universality of the desire to create encourages a diverse community to develop, with inclusivity as a core tenet. They can often provide opportunities for marginalised communities. Makerspaces such as the ‘Made in Za’atari’ space in Za’atari refugee camp have been used to give women in the camp a space in which they can utilise, share, and develop their skills both to improve wellbeing and create livelihoods. Meanwhile, projects such as Ambessa Play have provided opportunities for young people in refugee camps across the world to learn about kinetic energy and electronic components by creating a wind-up flashlight.  

 

Spaces of inclusive learning  

Maker projects also allow students to engage with their local communities, whether creating renewable energy installations, restoring community assets or educating the next generation of makers. Such projects raise the profile of sustainable development in the wider public and give students the opportunity to contribute to sustainable development in their neighbourhoods. 

 

3. Maker communities promote responsible consumption:

3.1 ESD rationale 

ESD does not just influence what we teach and how we teach; it also shapes who we are. A central tenet of ESD is that it helps to shape students, staff, and educational communities. When this happens, they are – in turn – better able to play their part in shaping the world around them.  

 

3.2 The contribution of makerspaces  

Even before the concept was popularised by the BBC’s ‘The Repair Shop’, repair cafes had begun to spring up across the country. Such facilities promote an ethos of repair and recycling by sharing of expertise amongst a community, a concept which aligns very closely with the maker movement. Items repaired might include furniture, electrical appliances, and ornaments. Related organisations like iFixit have also helped to promote responsible consumption and production through advocacy against built-in obsolescence and for the ‘Right to Repair’. 

The same principles apply to Making in textiles – sustainable fashion is a topic that excites many students both within and outside engineering, and makerspaces offer the opportunity for upcycling, garment repair and clothes shares. Students can learn simple techniques that will allow them to make better use of their existing wardrobes or of used clothing and in the process begin to change the consumption culture around them. At the University of Sheffield, our making community is currently planning an upcycled runway day, in which students will bring clothing that is in need of refresh or repair from their own wardrobes or from local charity shops. Our team of peer-instructors and sewing specialists will be on hand to help students to customise, fit, and mend their clothes. In doing so, we hope to build an awareness of sustainable fashion amongst our students, enabling an upcycling fashion culture at the university.  

 

Conclusion: 

Education for Sustainable Development plays a vital role in enabling students to expand the knowledge and skills that they hold so that they can play their part in creating a sustainable future. Makerspaces offer a valuable route through which engineering students can engage with Education for Sustainable Development, including opportunities for applied learning, cross disciplinary connections, and responsible consumption.

Learning and teaching notes:

At COP26, H.E. President Muhammadu Buhari announced Nigeria’s commitment to carbon neutrality by 2050. This case involves an engineer who is one of the stakeholders invited by the president of Nigeria to implement an Energy Transition Plan (ETP). It requires the engineer, who is a professional and well experienced in renewable energy and energy transition, to deliver a comprehensive decarbonisation roadmap that will ensure net zero emissions.

This case study addresses two of AHEP 4’s themes: The Engineer and Society (acknowledging that engineering activity can have a significant societal impact) and Engineering Practice (the practical application of engineering concepts, tools and professional skills). To map this case study to AHEP outcomes specific to a programme under these themes, access AHEP 4 here and navigate to pages 30-31 and 35-37.

The dilemma in this case is presented in two parts. If desired, a teacher can use Part one in isolation, but Part two develops and complicates the concepts presented in Part one to provide for additional learning. The case allows teachers the option to stop at multiple points for questions and / or activities, as desired.

Dilemma – Part one:

You are an electrical engineer working as a technical consultant in an international organisation aiming to  transform the global energy system to secure a clean, prosperous, zero-carbon future for all. The organisation is one of the stakeholders invited by the federal government of Nigeria to implement the country’s new Energy Transition Plan (ETP) and you are given the task of creating a comprehensive decarbonisation roadmap and presenting it at the stakeholder meeting.

 

Optional STOP for questions and activities:

1. Discussion: In what ways could an electrical engineer bring needed expertise to the ETP? Why are engineers essential to ensuring a zero-carbon future? Should engineers be involved in policy planning? Why or why not?

2. Activity: Wider context research: Nigeria is currently an oil-producing country. What might policy makers need to consider about this reality when implementing an ETP? How strongly should you advocate for a reduction of the use of fossil fuels in the energy mix?

3. Discussion and activity: List the potential benefits and risks to implementing the ETP. Are these benefits and risks the same no matter which country they are implemented in?

4. Activity: Research and outline countries that have attained a zero emission target. What are their energy distribution mixes? Based on this information, what approach should Nigeria take and why?

5. Activity: What will be your presentation strategy at the stakeholder meeting? What will you advocate for and why? What ethical justifications can you make for the plan you propose?

 

Dilemma – Part two:

At the stakeholder meeting, you were given the opportunity to present your decarbonisation roadmap and afterwards faced serious opposition by the chief lobbyist of the Fossil Fuel and Mining Association, Mr. Abiola. Mr. Abiola is of the opinion that because Nigeria contributes less than 1% to the global emissions, it should not be held accountable for climate change, and therefore no country-wide climate policy is necessary. Furthermore, he fears the domestic market for coal that is used to produce electricity as well as the global market for fossil fuels will shrink because of the new policy. He also argues that a shift away from coal and fossil fuels could result in challenges to the security of supply, since renewables are by definition unreliable and volatile. Other stakeholders, such as activists and environmental experts, also voiced different concerns and opinions. They argue that time has already run out, and no country can delay decarbonisation plans no matter how small their impact on the global total. This conflict has resulted in disagreements in the negotiation.

 

Optional STOP for questions and activities:

1. Debate: Do different countries have different ethical responsibilities when it comes to decarbonisation? Why or why not? If so, for what reasons?

2. Discussion: How should countries weigh the short-term versus long-term benefits and burdens of the energy transition? What role do governments and corporations play in managing those? What role should citizens play?

3. Discussion: How will you prepare for and handle opposing questions to your roadmap plan? 

4. Activity: Create a participatory stakeholder engagement plan embedded in the overall decarbonisation strategy.

5. Activity: How will you utilise the different renewable energy mix to provide 100% access to electricity and ensure security of supply as an electrical engineer?

Topic: Maintenance of an offshore wind farm.

Engineering disciplines: Mechanical; Energy.

Ethical issues: Sustainability; Risk.

Professional Situations: Public health and safety; Quality of work; Conflicts with leadership/management.

Educational level: Beginner.

Educational aim: Becoming Ethically Aware: determining that a single situation can be considered from a ethical point of view.

 

Learning and teaching notes:

The case is based on a genuine challenge raised by a multinational energy company that operates an offshore wind farm in the North Sea. It involves three professional engineers responsible for various aspects of the project to negotiate elements of safety, risk, environmental impact, and costs, in order to develop a maintenance plan for the wind turbine blades.

This case study addresses two of AHEP 4’s themes: The Engineer and Society (acknowledging that engineering activity can have a significant societal impact) and Engineering Practice (the practical application of engineering concepts, tools and professional skills). To map this case study to AHEP outcomes specific to a programme under these themes, access AHEP 4 here and navigate to pages 30-31 and 35-37.

This case is presented in two parts. In the first part, the perspectives and responsibilities of the three engineers are outlined so that students can determine what professional and ethical responsibilities are inherent in their roles. In the second part, a scenario is developed that puts the roles into potential conflict. Students then have the opportunity to work through a real-world brief that requires them to negotiate in order to present a solution to management. Teachers can choose to use Part one in isolation, or some or all of Part two to expand on the issues in the case. The case allows teachers the option to stop at multiple points for questions and / or activities, as desired.

Dilemma – Part one:

Offshore wind has huge benefits to the electricity industry as a renewable, low carbon resource.  The size and scale of the turbines, together with the remoteness – the wind farm referred to in this case is 200 km from shore – are a problem. However, it is a rapidly maturing industry and many of the issues around accessibility during installation have been solved. A wind farm is expected to generate for twenty years and so a system of inspection and maintenance needs to be put in place. At the same time, the environmental impact of industrial activity (including ongoing maintenance and repairs) needs to be managed in order to mitigate risks to ecosystem resources and services provided by the open sea.

In this wind farm there are one hundred turbines, each with three blades. The blades are 108 m long. Clearly, they need to be kept in good condition. However, inspecting the blades is a difficult and time consuming job.

There are three engineers that are responsible for various aspects of maintenance of the wind turbine blades. They are:

1. Blade engineer: My job is to make sure the blades are in good condition so that the wind farm operates as it was designed and generates as much power as possible. I am responsible for:

2. Health and safety engineer: My job is to make sure that the technicians who inspect and maintain the turbine blades are at minimal risk. I need to ensure compliance with:

3. Environmental engineer: My job is to ensure that the ecosystem is damaged as little as possible during turbine inspection and maintenance, and to rectify as best as possible any adverse effects that are incurred. After all, wind power is considered to be “green” energy and so wind farms should do as little damage to the environment as possible. This work helps:

 

Optional STOP for questions and activities:

1. Discussion: What sort of instances might cause damage to the turbine blades? (Possible answers: bird strike, collision with a vessel, storm, ice etc.)

2. Discussion: What problems might a damaged blade cause? (Possible answers: a damaged blade cannot generate properly; it might unbalance the other two blades until the whole turbine is affected. If a blade were to come loose it could strike another turbine blade, a vessel, sea creatures etc.)

3. Activity: Research how blade inspection is done. (Answer: a combination of photos from drones and reports from crew who need to use rope access to take a close look.)

a. If a drone is used, what issues might the drone have? (Answers: needs to be operated from a nearby vessel; weather (wind!); getting good resolution photos from a vibrating and moving drone; energy (battery) to power the drone.)

b. If a technician goes onsite, what issues are there with rope access? (Answers: time consuming; dangerous; can only be done in good weather; have to stop the turbine to access; training the inspection team; recording the findings.)

4. Discussion: What competing values or motivations might conflict in this scenario? Explain what constraints each engineer might be operating under and the potential conflicts between the roles.

5. Activity: Research what health and safety, environmental, and legal policies affect offshore wind farms. If they are in the open sea, which country’s laws are applied? Who is responsible for maintaining ecosystem health in the open sea? How are harms identified and mitigated?

 

Dilemma – Part two:

So, the blade engineer wants maintenance done effectively, with as little down time as possible; the H&S engineer wants it done safely, with as little danger to crew as possible; while the environmental engineer wants it done with as little damage to the ecosystem as possible. These three people must together develop an inspection plan that will be approved by upper management, who are largely driven by profitability – limited downtime in maintenance means increased profits as well as more energy delivered to customers.

 

Optional STOP for questions and activities:

The students are then presented with a brief that gives some background to the wind farms and the existing inspection regime. The brief is structured to allow engineering design, engineering drawing and technical research to take place alongside consideration of potential ethical dilemmas.

Brief: In teams of three, where each team member is assigned a different role outlined above (blade engineer, health and safety engineer, environmental engineer), propose a feasible method for blade inspection that:

Aspects to consider:

Teachers could task teams to work together to:

The pitch could include details of:

 

1. Activity: Working in groups, consider possible solutions:

a. Explore 2 or 3 alternatives to answer the need or problem, identifying the ethical concerns in each.

b. Analyse the alternative solutions to identify potential benefits, risks, costs, etc.

c. Justify the proposed solution.

 (Apart from the design process, this activity allows some discussion over the choice of solution. Looking at more than one allows the quieter students to speak out and justify their thinking.)

Learning and teaching notes:  

This case study involves an engineer who has to weigh personal values against professional codes of conduct when acting in the wake of the climate crisis. This case study allows students to explore motivations and justifications for courses of action that could be considered morally right but legally wrong.  

This case study addresses two of the themes from the Accreditation of Higher Education Programmes fourth edition (AHEP4): The Engineer and Society (acknowledging that engineering activity can have a significant societal impact) and Engineering Practice (the practical application of engineering concepts, tools and professional skills). To map this case study to AHEP outcomes specific to a programme under these themes, access AHEP 4  here and navigate to pages 30-31 and 35-37. 

The dilemma in this case is presented in three parts. If desired, a teacher can use Part one in isolation, but Parts two and three develop and complicate the concepts presented in Part one to provide for additional learning. The case study allows teachers the option to stop at multiple points for questions and/or activities, as desired.

Summary: 

Kelechi is a civil engineer in a stable job, working on the infrastructure team of a County Council that focuses on regeneration and public realm improvements. Kelechi grew up in an environment where climate change and its real impacts on people was discussed frequently. She was raised with the belief that she should live as ethically as possible, and encourage others to consider their impact on the world. These beliefs were instrumental in leading Kelechi into a career as a civil engineer, in the hope that she could use her skills and training to create a better world. In one of her engineering modules at university, Kelechi met Amanda, who encouraged her to join a student group pushing for sustainability within education and the workplace. Kelechi has had some success with this within her own job, as her employer has been willing to participate in ongoing discussions on carbon and resilience, and is open to implementing creative solutions.  

But Kelechi is becoming frustrated at the lack of larger scale change in the wake of the climate emergency. Over the years she has signed petitions and written to her representatives, then watched in dismay as each campaign failed to deliver real world carbon reduction, and as the government continued to issue new licenses for fossil fuel projects. Even her own employers have failed to engage with climate advocates pushing for further changes in local policy, changes that Kelechi believes are both achievable and necessary. Kelechi wonders what else she can do to set the UK – if not the world – on a path to net zero. 

 

Dilemma – Part one: 

Scrolling through a news website, Kelechi is surprised to see a photo of her friend and ex-colleague Amanda, in a report about climate protesters being arrested. Kelechi messages Amanda to check that she’s ok, and they get into a conversation about the protests. Amanda is part of a climate protest group of STEM professionals that engages in non-violent civil disobedience. The group believes that by staging direct action protests they can raise awareness of the climate emergency and ultimately effect systemic change.  

Amanda tries to convince Kelechi to join the group and protest with them. Amanda references the second principle of the Statement of Ethical Principles published by the Engineering Council and the Royal Academy of Engineering: “Respect for life, law, the environment and public good.” Amanda believes that it is ok to ignore the tenet about respect for the law in an effort to safeguard the other three, and says that there have been plenty of unjust laws throughout history that have needed to be protested in order for them to be changed for the public good. She also references another part of the Statement: that engineers should ”maximise the public good and minimise both actual and potential adverse effects for their own and succeeding generations”. Amanda believes that by protesting she is actually fulfilling her duty to uphold these principles.  

Kelechi isn’t sure. She has never knowingly broken the law before, and is worried about being arrested. Kelechi consults her friend Max, who is a director of a professional engineering institution, of which Kelechi is a member. Max, whilst she has some sympathies for the aims of the group, immediately warns Kelechi away from the protests. “Forget about being arrested; you could lose your job and end your career.”  

 

Optional STOP for questions and activities: 

1. Discussion: What personal values will Kelechi have to weigh in order to decide whether or not to take part in a civil disobedience protest? 

2. Discussion: Consider the tenet of the Statement of Ethical Principles “Respect for life, law, the environment and public good.” To what extent (if at all) do the four tenets of this ethical principle come into conflict with one another in this situation? Can you think of other professional situations in which they might conflict? 

3. Discussion: Is breaking the law always unethical? Are there circumstances when breaking the law might be the ethical thing to do in the context of engineering practice? What might these circumstances be? 

4. Discussion: To what extent (if at all) does the content of the Statement of Ethical Principles make a case for or against being part of a protest where the law is broken?  

5. Discussion: Following on from the previous question – does it make a difference what is being protested, if a law is broken? For example, is protesting fossil fuels that lead to climate change different from protesting unsafe but legal building practices, such as cladding that causes a fire risk? Why? 

6. Activity: Research other professional codes of engineering: do these have clear guidelines for this situation? Assemble a bibliography of other professional codes or standards that might be relevant to this scenario. 

7. Discussion: What are the potential personal and professional risks or benefits for Kelechi if she takes part in a protest where the law is broken? 

8. Discussion: From a professional viewpoint, should Kelechi take part in the protest? What about from a personal viewpoint? 

 

Dilemma – Part two: 

After much deliberation, Kelechi decides to join the STEM protest group. Her first protest is part of a direct action to blockade a busy London bridge. To her own surprise, she finds herself volunteering to be one of two protesters who will climb the cables of the bridge. She is reassured by the risk assessment undertaken by the group before selecting her. She has climbing experience (although only from her local leisure centre), and safety equipment is provided.  

On the day of the protest, Kelechi scales the bridge. The police are called and the press arrive. Kelechi stays suspended from the bridge for 36 hours, during which time all traffic waiting to cross the bridge is halted or diverted. Eventually, Kelechi is convinced that she should climb down, and the police arrest all of the protesters.  

Later on, Kelechi is contacted by members of the press, asking for a statement about her reason for taking part in the protest. Kelechi has seen that press coverage of the protest is so far overwhelmingly negative, and poll results suggest that the majority of the public see the protesters’ actions as selfish, inconvenient, and potentially dangerous, although some have sympathy for their cause. “What if someone died because an ambulance couldn’t use the bridge?” asks someone via social media. “What about the five million deaths a year already caused by climate change?” asks another, citing a recent news article 

Kelechi would like to take the opportunity to make her voice heard – after all, that’s why she joined the protest group – but she isn’t sure whether she should mention her profession. Would it add credibility to her views? Or would she be lambasted because of it? 

 

Optional STOP for questions and activities: 

1. Discussion: What professional principles or codes is Kelechi breaking or upholding by scaling the bridge?  

2. Activity: Compare the professional and ethical codes for civil engineers in the UK and elsewhere. How might they differ in their guidance for an engineer in this situation?  

3. Activity: Conduct a risk assessment for a) the protesters who have chosen to be part of this scenario, and b) members of the public who are incidentally part of this scenario. 

4. Discussion: Who would be responsible if, as a direct or indirect result of the protesters blocking the bridge, a) a member of the public died, or b) a protester died? Who is responsible for the excess deaths caused directly or indirectly by climate change? 

5. Discussion: How can Kelechi best convey to the press and public the quantitative difference between the short-term disruption caused by protests and the long-term disruption caused by climate change? 

6. Discussion: Should Kelechi give a statement to the press? If so, should she discuss her profession? What would you do in her situation? 

7. Activity: Write a statement for Kelechi to release to the press. 

8. Discussion: Suggest alternative ways of protesting that would have as much impact in the news but potentially cause less disruption to the public. 

 

Dilemma – Part three: 

Kelechi decides to speak to the press. She talks about the STEM protest group, and she specifically cites the Statement of Ethical Principles as her reason for taking part in the protest: “As a professional civil engineer, I have committed to acting within our code of ethics, which requires that I have respect for life, the environment and public good. I will not just watch lives be destroyed if I can make a difference with my actions.”  

Whilst her statement gets lots of press coverage, Kelechi is called out by the media and the public because of her profession. The professional engineering institution of which Kelechi is a member receives several complaints about her actions, some from members of the public and some from other members of the institution. “She’s bringing the civil engineering profession into disrepute,” says one complaint. “She’s endangering the public,” says another. 

It’s clear that the institution must issue a press release on the situation, and it falls to Kelechi’s friend Max, as a director of the institution, to decide what kind of statement to put out, and to recommend whether Kelechi’s membership of the institution could – or should – be revoked. Max looks closely at the institution’s Code of Professional Conduct. One part of the Code says that “Members should do nothing that in any way could diminish the high standing of the profession. This includes any aspect of a member’s personal conduct which could have a negative impact upon the profession.” Another part of the Code says: “All members shall have full regard for the public interest, particularly in relation to matters of health and safety, and in relation to the well-being of future generations.” 

As well as the institution’s Code of Conduct, Max considers the historic impact of civil resistance in achieving change, and how those engaging in such protests – such as the suffragettes in the early 1900s – could be viewed negatively at the time, whilst later being lauded for their efforts. Max wonders at what point the tide of public opinion begins to turn, and what causes this change. She knows that she has to consider the potential impacts of the statement that she puts out in the press release; how it might affect not just her friend, but the institution’s members, other potential protesters, and also her own career.  

 

Optional STOP for questions and activities: 

1. Discussion: Historically, has civil resistance been instrumental or incidental in achieving systemic change? Research to find out if and when engineers have been involved in civil resistance in the past. 

2. Discussion: Could Kelechi’s actions, and the results of her actions, be interpreted as having “a negative impact on the profession”? 

3. Discussion: Looking at Kelechi’s actions, and the institution’s code of conduct, should Max recommend that Kelechi’s membership be revoked? 

4. Discussion: Which parts of the quoted code of conduct could Max emphasise or omit in her press release, and how might this affect the tone of her statement and how it could be interpreted? 

5. Activity: Debate which position Max should take in her press release: condemning the actions of the protesters as being against the institution’s code of conduct; condoning the actions as being within the code of conduct; remaining as neutral as possible in her statement. 

6. Discussion: What are the wider impacts of Max’s decision to either remain neutral, or to stand with or against Kelechi in her actions?  

7. Activity: Write a press release for the institution, taking one of the above positions. 

8. Discussion: Which other authorities or professional bodies might be impacted by Max’s decision? 

9. Discussion: What are the potential impacts of Max’s press release on the following stakeholders, and what decisions or actions might they take because of it? Kelechi; Kelechi’s employer; members of the STEM protest group; the institution; institution members; government policymakers; the media; the public; the police; fossil fuel businesses; Max’s employers; Max herself.
