Who is this article for?: This article should be read by educators at all levels in higher education who are seeking an understanding of the connection between complex systems in engineering education and public policy. 

Related INCOSE Competencies: Toolkit resources are designed to be applicable to any engineering discipline, but educators might find it useful to understand their alignment to competencies outlined by the International Council on Systems Engineering (INCOSE). The INCOSE Competency Framework provides a set of 37 competencies for Systems Engineering within a tailorable framework that provides guidance for practitioners and stakeholders to identify knowledge, skills, abilities and behaviours crucial to Systems Engineering effectiveness. A free spreadsheet version of the framework can be downloaded. 

This resource relates to the Systems Thinking and Critical Thinking INCOSE competencies.

AHEP mapping: This resource addresses several of the themes from the UK’s Accreditation of Higher Education Programmes fourth edition (AHEP4):  Analytical Tools and Techniques (critical to the ability to model and solve problems), and Integrated / Systems Approach (essential to the solution of broadly-defined problems). Additionally, this resource addresses the Communication theme. 

 

Premise: 

In engineering there is often a direction/endpoint: the building is completed, the project finalised, the product made.  In policy, different groups want different things: the goals may shift and the values become contested, uncertain, and emergent (depending on ‘events’) – more of an on-going ‘dance’ than a final outcome. So what happens when the relatively simple/complicated field of engineering and physical systems bump into the complex/chaotic and often tumultuous, emotional, and values-laden arena of public policy? 

 

Engineering complexity and public policy: 

For the past 30+ years, there has been a growing literature on complex systems/complexity and policy making, and more recently, increasing work within UK government circles (2023 UK Systems Thinking Toolkit ; 2020 Magenta Book – Handling Complexity in Policy Evaluation) on how to use systems and complex systems thinking to better understand public policy. This short article introduces one popular tool for conceptualising complexity and policy: the Complexity Diagram (also known as a Stacey Diagram/Matrix) and how it can help people to see the larger policy picture and an engineer’s role in it.  

The diagram was originally developed by Professor Ralph Stacey in the 1990s and has been used widely in complexity and systems thinking (including in the aforementioned 2020 Magenta Book). The description below is from Geyer and Rihani (2010), and there is also a related YouTube video 

Figure 1: A Version of the Complexity Diagram. Harrison and Geyer (2022).

As shown in Figure 1, the Complexity Diagram combines two axes based on the degree of certainty and the degree of agreement for a particular policy area. High levels of certainty indicate that the issue is well known, understood, and data is available, while low levels of certainty imply that it is unknown and contested with poor or no data. Meanwhile, high levels of agreement denote substantial public agreement over the issue and its solution, while low levels of certainty imply substantial public debate and disagreement. These two axes create five main zones of decision-making: 

It is important to note that the complexity diagram can be applied to any level of policy. 

 

Complexity and policy in practice:

At a local level, one example of the complexity diagram in practice would be the need for transmission masts that emerged with the development of mobile phones. The technological need for some form of mast system was relatively clear and particular specifications (distance of coverage, etc.) could be mapped out. However, there was substantial political disagreement over where they should be placed (In which neighbourhoods? Near schools?). Moreover, there were clear judgemental debates over whether the masts could or should be disguised (What was the best disguise? How much should locals be involved in making these decisions?). In many areas, decisions over mast placements were a mixture of technical demands, political consultation and debate, and chance (having easily accessible land and infrastructure available). Occasionally, they involved the techno-social fears of physical harm and led to protests and occasional acts of destruction against masts.  

At a national/global level, one can easily see climate change as a case for using the Complexity diagram. The evidence for climate change is very clear. Engineering a solution to it is relatively straightforward – reduce CO2 outputs. However, as demonstrated by the continued lack of global/national consensus, the politics surrounding this are fraught with different values and political debates are clearly part of the process for resolving this issue. At the same time, there is substantial debate over the specific type of transformation required (reduce consumption, green energy, nuclear power), even by the experts, and judgemental decisions linked to particular situations will be needed as well. Clearly, a mix of approaches is essential, particularly in relation to strong emotional elements that the issue generates. 

Does the Stacey Diagram solve all of these difficulties? NO! However, it does allow students to recognise that there are a range/spectrum of policy systems and system dynamics and not a hierarchy with quantitative-rational/evidence-based approaches at the top. When confronting a complex problem embedded in physical and human systems (building a new hospital, altering an urban electrical grid, changing a road system), engineering students should try to recognise the type of zone they are dealing with and adjust their approach to fit the situation.  Using the diagram to reflect on this range and choose the right approach for the right situation is fundamental to learning that the engineer’s role in society is more than just a builder of things. She/he may also be playing a key role in social/political debates and policy choices that will continually change over time and place. Hence, the policy world is more akin to a dance with multiple actors, often pulling in different directions, than orderly Newtonian science.

Learning and teaching notes:

The two complementary workshops, Climate Fresk and En-ROADS, are introduced to situate Renewable Energy Technologies within the wider context of the Net Zero transition. Their purpose is first to deepen students’ understanding of the climate science that underpins climate change as the driver of technical innovation, and then to broaden awareness of the social, economic, political, and environmental factors that shape global decarbonisation pathways. Building on this foundation, the workshops shift focus to the policy levers required to enable systems change – highlighting, often with surprising insights, their relative effectiveness in reducing emissions and limiting temperature rise. Together, they provide the context for a Renewable Energy Technologies module, where attention turns to the role of renewables and other low-carbon technologies as climate solutions. The central takeaway is that there is no single “silver bullet” solution; instead, a coordinated “silver buckshot” approach is essential.  

Learners do not require any prior learning in the area of climate change or climate solutions for these workshops. The workshops are the perfect introduction to these. Climate Fresk facilitator training begins with attending a workshop as a participant, followed by a session on facilitation. Staff can train via local workshops, the CF MOOC and peer-to-peer practice, or through official training, enabling institutions to build a self-sustaining community of facilitators at minimal cost.

Activity overview: 

This activity utilises off-the-shelf educational tools in the form of the Climate Fresk workshop and the En-Roads Climate Simulator tool. These are used in two separate (but connected) workshops adapted from the guided assignment that is presented in the resources above. These are not intended to be run back-to-back. In fact, some gap (of days) in between is desirable as together, this would be too exhausting, and also give time for reflection in between. 

Figure 1. Using Climate Fresk and En-ROADS as complementary workshops focusing on ‘the climate problem’ and ‘climate solutions’. 

A key aspect of both workshops is highlighting the need for systems thinking in both understanding the problem of, and exploring the solutions to, climate change. This involves introducing students to the cause and effects of climate change, feedback loops and the concept of tipping points – both in terms of climate tipping points (BBC Sounds – The Climate Tipping Points, no date) that can potentially trigger irreversible changes in the climate system, as well as positive, social tipping points (TEDx Talks 2023) that once crossed can shift social norms, and how policies can affect this. It allows discussions around leverage points in the context of climate solutions and policies, which Donella Meadows describes as where “a small shift in one thing can produce big changes in everything”. 

 

Part one: Climate Fresk workshop: Understanding the problem of climate change (or the ‘science piece’): 

Overview:

Climate Fresk is a 2-2.5 hour facilitator-led gamified workshop based on the latest IPCC report, where participants work in groups to build a causal-loop diagram (or fresk) of the Earth’s climate system using specially designed cards. The activity encourages discussion, challenges assumptions, and develops systems thinking by illustrating the interconnections, feedback loops, and tipping points of climate change. In doing so, it supports UNESCO Education for Sustainable Development competencies in anticipatory and systems thinking, helping participants understand the potential impacts of climate dynamics on ecological, social, and economic systems in a way that is accessible. 

Scalability and setup:

The Climate Fresk workshop can be delivered to almost any number of participants, limited only by the size of the space, the number of trained facilitators available, and the number of card decks. Participants are usually divided into groups of 8 (10 at a push), each working around a table roughly 2m x 1m in size. Each group (table) requires a dedicated facilitator to guide the process. 

Facilitation and training:

Facilitators must be trained before running the activity. Training can be undertaken through official Climate Fresk courses (see resources) or, once enough experience has been built, in-house peer-to-peer training supported by staff development units. Facilitators use a “crib sheet” containing guiding questions and timings to help keep groups on track. 

Workshop materials:

The Fresk uses a deck of 42 cards, each representing a cause, effect, or impact within the climate system-ranging from fossil fuel use across industry, buildings, transport and agriculture, to wider impacts on society, biodiversity, and ecosystems. Each card has a graphic on one side and explanatory text on the other, which participants use to determine its role in the system. 

Learning process:

Over the session, participants collaboratively arrange the cards on a large sheet of paper to construct a causal-loop diagram of the climate system. In doing so, they identify drivers of carbon emissions, critical carbon sinks, feedback loops, and potential tipping points. The activity encourages discussion, challenges assumptions, and introduces key climate science terminology, while making visible the complex interdependencies of Earth systems. 

Reflection and discussion:

After constructing the Fresk, participants are encouraged to reflect on how the process made them feel (normative competency) and what insights they gained. This is followed by open discussion on mitigation strategies and possible solutions. In a standard Climate Fresk workshop, around 45 minutes is devoted to this. However, when combined with the En-Roads simulator, this discussion naturally transitions from the “problem space” of the Fresk workshop to the “solutions space” of the subsequent En-Roads workshop, where participants explore the realistic impacts of different climate solutions, their co-benefits, and the equity issues they raise – engaging participants in deeper systems-level thinking. 

 

Part two: En-ROADS workshop: ‘Exploring the solutions’ to climate change (or the ‘policy piece’):  

Overview:

This En-ROADS workshop can be run from one to two hours, and can follow a role-play format, where participants are asked to take on the role of policymakers, exploring different policy options to limit global temperatures to 1.5oC (or 2oC). They are introduced to the workshop by telling them “you are policymakers tasked with limiting global heating”. En-Roads is a climate change simulator developed by Climate Interactive and MIT that uses roleplay to explore global policy interventions for limiting temperature rise. It enables participants—from students to policymakers—to test combinations of climate solutions, examine trade-offs and unintended consequences, and understand that no single “silver bullet” exists. The workshop develops UNESCO Education for Sustainable Development competencies in anticipatory, systems, critical, and strategic thinking, while highlighting the challenges of achieving policy consensus across diverse stakeholders.

Water wars: managing competing water rights 

This example demonstrates how the questions provided in the accompanying rubric can be used to assess the competencies stipulated at each level. Although we have focused on ‘Water Wars’ here, the suggested assessment questions have been designed in such a way that they can be used in conjunction with the case studies available within the toolkit, or with another case study that has been created (by yourself or elsewhere) to outline an ethical dilemma. 

Year 1 

Personal values: What is your initial position on the issue? Do you see anything wrong with how DSS are using water? Why, or why not?

Professional responsibilities: What ethical principles and codes of conduct are relevant to this situation?

Ethical principles and codes of conduct can be used to guide our actions during an ethical dilemma. How does the guidance provided in this case align/differ with your personal views? (This is a question we had created in addition to those provided within the case study to meet the requirements stipulated in the accompanying rubric.)

What are the moral values involved in this case and why does it constitute an ethical dilemma? (This is a question we had created in addition to those provided within the case study to meet the requirements stipulated in the accompanying rubric.)

What role should an engineer play in influencing the outcome? What are the implications of not being involved? (This is a question we had created in addition to those provided within the case study to meet the requirements stipulated in the accompanying rubric.)

Year 2 

Formulate a moral problem statement which clearly states the problem, its moral nature and who needs to act. (This is a question we had created in addition to those provided within the case study to meet the requirements stipulated in the accompanying rubric.)

Stakeholder mapping: Who are all the stakeholders in the scenario? What are their positions, perspective and moral values?

Stakeholder  Perspectives/interests  Moral values 
Data Storage Solutions (DSS)  Increasing production in a profitable way; meeting legal requirements; good reputation to maintain/grow customer base.  Accountability; sustainability (primarily economic). 
Farmers’ union  Represent farmers who suffer from economic implications associated with costly irrigation.  Accountability; environmental sustainability; justice. 
Farm  The farm (presumably) benefits from DSS using the land.  Ownership and property; environmental sustainability; justice. 
Local Green Party  Represent views of those concerned about biodiversity. May be interested in opening of green battery plant.  Human welfare; environmental sustainability; justice. 
Local Council  Represent views of all stakeholders and would need to consider economic benefits of DSS (tax and employment), the need of the university and hospital, as well as the needs of local farmers and environmentalists. May be interested in opening of green battery plant.  Human welfare and public health; trust; accountability; environmental sustainability; justice. 
Member of the public  This may depend on their beliefs as an individual, their employment status and their use of services such as the hospital and university. Typically interested in low taxes/responsible spending of public money. May be interested in opening of green battery plant.  Human welfare; trust; accountability; environmental sustainability; justice. 
Stakeholders using DSS data storage  Reliable storage. They may also be interested in being part of an ethical supply chain.  Trust; privacy; accountability; autonomy. 
Non-human stakeholders  Environmental sustainability. 

 

What are some of the possible courses of action in the situation. What responsibilities do you have to the various stakeholders involved? What are some of the advantages and disadvantages associated with each? (Reworded from case study.)

What are the relevant facts in this scenario and what other information would you like to help inform your ethical decision making? (This is a question we had created in addition to those provided within the case study to meet the requirements stipulated in the accompanying rubric.)

 

 

Year 2/Year 3  

(At Year 2, students could provide options; at Year 3 they would evaluate and form a judgement.) 

Make use of ethical frameworks and/or professional codes to evaluate the options for DSS both short term and long term. How do the uncertainty and assumptions involved in this case impact decision making?

Option  Consequences  Intention  Action 
Keep using water  May lead to expansion and profit of DSS and thus tax revenue/employment and supply. 

Reputational damage of DSS may increase. Individual employee piece of mind may be at risk. 

Farmers still don’t have water and biodiversity still suffers which may have further impact long term. 

Intention behind action not consistent with that expected by an engineer, other than with respect to legality  Action follows legal norms but not social norms such as good will and concern for others. 
Keep using the water but limit further work  May limit expansion and profit of DSS and thus tax revenue/employment and supply. 

Farmers still don’t have water and biodiversity still suffers and may have further impact long term. This could still result in reputation damage. 

Intention behind action partially consistent with that expected by an engineer.  Action follows legal norms but only partially follow social norms such as good will and concern for others. 
Make use of other sources of water  Data storage continues. 

Potential for reputation to increase. 

Potential increase in cost of water resulting in less profit potentially less tax revenue/employment. 

Farmers have water and biodiversity may improve.

Alternative water sources may be associated with the same issues or worse. 

Intention behind action seems consistent with that expected by an engineer. However, this is dependent upon 

whether they chose to source sustainable water with less impact on biodiversity etc. 

This may be dependent on the degree to which DSS proactively source sustainable water. 
Reduce work levels or shut down  Impact on profit and thus tax revenue/employment and supply chain. Farmers have water and biodiversity may improve. 

May cause operational issues for those whose data is stored. 

Seems consistent with those expected of engineer. Raises questions more generally about viability and feasibility of data storage.  Action doesn’t follow social norms of responsibility to employees and shareholders. 
Investigate other cooling methods which don’t require as much water/don’t take on extra work until another method identified. 
May benefit whole sector. 

May cause interim loss of service. 

 

This follows expectations of the engineering profession in terms of evidence-based decision making and consideration for impact of engineering in society.  It follows social norms in terms of responsible decision making.

“A new report from the National Engineering Policy Centre about resource efficiency and demand reduction for critical materials to support the UK’s existing Net Zero Strategy.

This report provides an overview of the underutilised policy options for achieving reductions in demands for critical materials and dependency on imports of scarce materials.

It presents a range of policy and engineering interventions around three main areas of demand-side resource management. These include: infrastructure and technology planning, design and design skills and circular economy.

The report concludes with 25 recommendations for policymakers which will help the UK cut its critical material footprint. Lead recommendations from the report call for: an integrated materials strategy, a National Materials Data Hub, infrastructure planning for material sustainability, and a new target to halve the UK’s material footprint.

The report also makes specific recommendations for targeted action, such as committing to the ban on single-use vapes, and improving repair and recycling of electronics to reduce e-waste.

Without intervention, the UK risks not achieving its Net Zero strategy and exposure to future economic uncertainty.” – The Royal Academy of Engineering

Learning and teaching notes:  

This is an example project that could be adapted for use in a variety of contexts. It asks students to devise a “sustainability dashboard” that can not only track indicators of river system sustainability through technical means, but also communicate the resulting data to the public for the purpose of policy decisions. Teachers should ideally select a local river system to focus on for this project, and assign background reading accordingly.

Introduction: 

Two vital and unique resources for the planet are water and air. Any alterations in their composition can have detrimental effects on humans and living organisms. Water uses across New Mexico are unsustainable. Reduced precipitation and streamflows cause increased groundwater use and recharge.  Serious omissions in state water policy provide no protection against complete depletion of groundwater reserves.   

The water governance status quo in New Mexico will result in many areas of New Mexico running out of water, some sooner, some later, and some already have. Because Water is Life, water insecurity will cause economic insecurity and eventual collapse.   

Water resources, both surface and groundwater, and total water use, determine the amount of water use that can be sustained, and then reduce total water use if New Mexico is to have water security.  The public must therefore recognise that action is required. Availability of compiled, accessible data will lead to and promote our critical need to work toward equitable adaptation and attain sustainable resiliency of the Middle Rio Grande’s common water supply and air quality. 

A data dashboard is needed to provide on-line access to historical, modern, and current perspectives on water, air quality, health, and economic information.  A dashboard is needed to help inform the public about why everyone and all concerned citizens, institutions and levels of government must do their part! 

 

Project brief:  

The Middle Rio Grande region of New Mexico has particular sustainability and resilience requirements and enforceable legal obligations (Rio Grande Compact) to reduce water depletions of the Rio Grande and tributary groundwater to sustainable levels.  However, there is a lack of accessible depictions of the Middle Rio Grande’s water supply and demand mismatch. Nothing publicly accessible illustrates the surface water and groundwater resources, water uses, and current water depletions that cannot be sustained even if water supplies were not declining.  Therefore, there is a corresponding lack of public visibility of New Mexico’s water crisis, both in the Middle Valley and across New Mexico. Local water institutions and governments are siloed and have self-serving missions and do not recognise the limits of the Middle Valley’s water resources.   

A water data dashboard is needed to provide online open access to historical, modern, and current perspectives on water inflows, outflows, and the change in stored surface and groundwater.  This dashboard should inform the public about why everyone and all water institutions and levels of government must do their part!

Educational aim: Engaging in ethical judgement: reaching moral decisions and providing the rationale for those decisions.

 

Learning and teaching notes:

The case involves an engineering student whose personal choices may affect her future professional experience. It highlights both micro- and macro-ethical issues, dealing with the ways that individual actions and decisions can scale to create systemic challenges.

An ethical and responsible engineer should know how to work with and use digital information responsibly. Not all materials available online are free to use or disperse. To be digitally literate, a person must know how to access, evaluate, utilise, manage, analyse, create, and interact using digital resources (Martin, 2008). It is important to guide engineering students in understanding the media landscape and the influence of misleading information on our learning, our political choices, and our careers. A large part of critical digital literacy is evaluating information found on the web. For students working on a research project or an experiment, accessing accurate information is imperative. This case study offers several approaches to engaging students in the critique and improvement of their critical digital literacy skills. The foundations of this lesson can be applied in multiple settings and can be expanded to cover several class periods or simplified to be inserted into a single class.

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 the Summary and Part one in isolation, but Part two develops and complicates the concepts presented in the Summary and 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.

Summary:

Katherine is a biomedical engineering student in her 3rd year in 2022, and will have a placement in a community hospital during her last term at university. She plans to pursue a career in public health after seeing what her country went through during the Covid-19 pandemic. She wants to contribute to the systems that can prevent and track public health risks from growing too large to manage, as happened with Covid-19. She is motivated by improving systems of research and treatment for emerging diseases and knows that communication between a variety of stakeholders is of the utmost importance.

 

Optional STOP for questions and activities:

1. Discussion: What can you determine about Katherine’s values and motivation for her studies and her choice of career?

2. Discussion: How do you connect with her mission to improve diagnostic and treatment systems for public health threats?

3. Discussion: Who should be responsible for the messaging and processes for public health decisions? How are engineers connected to this system?

4. Activity: Research the Covid-19 vaccine rollout in the United Kingdom versus other countries – how did power, privilege, and politics influence the response?

5. Activity: Research current public health concerns and how they are being communicated to the public. In what ways might engineers affect how and what is communicated?

 

Dilemma – Part one:

As Katherine approaches the winter holiday season, she makes plans to visit her grandmother across the country. She hasn’t seen her since before the Covid-19 pandemic and is excited to be around her extended family for the holidays once again. However, she receives an email from her cousin informing everyone that he and his family are not vaccinated against Covid-19 because the whole vaccination operation was forced upon citizens and they refused to participate. Katherine is immediately worried for her grandmother – at 85 years old, she is at a higher risk than most – and for her brother, who suffers from Addison’s disease, an autoimmune disorder. Additionally, if Katherine comes into contact with Covid-19 while celebrating the holidays with her family, she could suffer repercussions at both her university and the hospital where she will work for her placement.

 

Optional STOP for questions and activities:

1. Discussion: How can Katherine communicate with her cousin about her concerns for her brother and grandmother? How might she use her expertise as a biomedical engineer in this conversation?

2. Discussion: What kind of information will be most convincing to support her decision? What sources would provide the evidence she is looking for, and which ones would provide counter arguments?

3. Discussion: What impacts might the decision have on Katherine’s position as a student or in the hospital?

4. Discussion: Do engineers, scientists, and medical professionals have more of an obligation to promote and adhere to public health guidance? Why or why not?

5. Activity: Talk to people in your life about their experience of navigating the Covid-19 vaccine. Did they choose to get it as soon as it was available? Did they avoid getting the vaccine for particular reasons? Were there impacts on their personal relationships or work because of their choices about the vaccine?

6. Activity: Research some of the impacts on individuals with health concerns and comorbidities in regard to Covid-19 and other viruses or public health concerns. How do these experiences match with or differ from your own?

7. Activity: Investigate the different ways that engineers were involved in vaccination development and response.    

 

Dilemma – Part two:

Katherine went back to university after a lengthy break for the holidays and immediately registered for an account on Facebook as a brand-new user. She was in such a hurry to have her profile up that she did not take the time to configure any privacy settings. She stayed up late reading an article about Covid-19  that had been posted on the website of one of the online newspapers. Before she posted this report on her own Facebook page, she did not verify the accuracy of the information or the source of the information.

 

Optional STOP for questions and activities:

1. Discussion: What kind of impact might this social media activity have on Katherine’s position as a student or in the company/organisation/hospital she is working for as an intern? What should Katherine be worried or concerned about after posting information?

2. Discussion: Do social media companies collect or ask for any other non-essential information from you? Why does the website claim that they are collecting or asking for your information? Does the website share/sell/trade the information that they collect from you? With whom does the website share your collected information? How long does the website keep your collected information? Does the website delete your information, or simply de-personalise it?

3. Discussion: Regarding question 2, how are engineers involved with products, processes, or services that enable those choices and actions?

4. Discussion: What is real and fake news? How do you know? What do you look for to know if it is real or fake news (share guidelines)? Do you expect it to be easy to spot fake news? Why should we care if people distribute and believe fake news?

Students are particularly susceptible to being duped by propaganda, misleading information, and fake news due to the significant role that information and communication technology which is problematic to verify plays in their everyday life. Students devote a significant portion of their time to participating in various forms of online activity, including watching television, playing online games, chatting, blogging, listening to music, posting photos of themselves on social networking sites, and searching for other individuals with whom they can engage in online conversation. Students owe a significant portion of what they know about the world and how they perceive reality to the content that they read online. While many people share reliable and positive information online, others may engage in negative impact information sharing:

5. Discussion: What are some other examples of how engineering might fall prey to negative impact information sharing?

6. Discussion: How might engineers help address the problem of fake news and negative impact information sharing?

Learning and teaching notes: 

This case study involves an engineer hired to develop and install an Industrial Internet of Things (IIoT) online machine monitoring system for a manufacturing company. The developments include designing the infrastructure of hardware and software, writing the operation manuals and setting policies. The project incorporates a variety of ethical components including law and policy, stakeholders, and risk analysis. 

This case study addresses three of the themes from the Accreditation of Higher Education Programmes fourth edition (AHEP4): Design and Innovation (significant technical and intellectual challenges commensurate the level of study), 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 Part two and Part 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: 

IIoT is a new technology that can provide accurate condition monitoring and predict component wear rates to optimise machine performance, thereby improving the machining precision of the workpiece and reducing the production cost.   

Oxconn is a company that produces auto parts. The robotic manipulators and other automation machines on the production line have been developed at considerable cost and investment, and regular production line maintenance is essential to ensure its effective operation. The current maintenance scheme is based on routine check tests which are not reliable and efficient. Therefore Oxconn has decided to install an IIoT-based machine condition monitoring system. To achieve fast responses to any machine operation issues, the machine condition data collected in real time will be transferred to a cloud server for analysis, decision making, and predictive maintenance in the future. 

 

Dilemma – Part one – Data protection on customers’ machines:

You are a leading engineer who has been hired by Oxconn to take charge of the project on the IIoT-based machine monitoring system, including designing the infrastructure of hardware and software, writing the operation manuals, setting policies, and getting the system up and running. With your background in robotic engineering and automation, you are expected to act as a technical advisor to Oxconn and liaise with the Facilities, Security, Operation, and Maintenance departments to ensure a smooth deployment. This is the first time you have worked on a project that involves real time data collection. So as part of your preparation for the project, you need to do some preliminary research as to what best practices, guidance, and regulations apply. 

 

Optional STOP for questions and activities: 

1. Discussion: What are the legal issues relating to machine condition monitoring? Machines’ real-time data allows for the identification of production status in a factory and is therefore considered as commercial data under GDPR and the Data Protection Act (2018). Are there rules specifically for IIoT, or are they the same no matter what technology is being used? Should IIoT regulations differ in any way? Why? 

2. Discussion: Sharing data is a legally and ethically complex field. Are there any stakeholders with which the data could be shared? For instance, is it acceptable to share the data with an artificial intelligence research group or with the public? Why, or why not? 

3. Discussion: Under GDPR, individuals must normally consent to their personal data being processed. For machine condition data, how should consent be handled in this case? 

4. Discussion: What ethical codes relate to data security and privacy in an IIoT scenario?  

5. Activity: Undertake a technical activity that relates to how IIoT-based machine monitoring systems are engineered. 

6. Discussion: Based on your understanding of how IIoT-based machine monitoring systems are engineered, consider what additional risks, and what kind of risks (such as financial or operational), Oxconn might incur if depending on an entirely cloud-based system. How might these risks be mitigated from a technical and non-technical perspective? 

 

Dilemma – Part two – Computer networks security issue brought by online monitoring systems:

The project has kicked off and a senior manager requests that a user interface (UI) be established specifically for the senior management team (SMT). Through this UI, the SMT members can have access to all the real-time data via their computers or mobiles and obtain the analysis result provided by artificial intelligence technology. You realise this has implications on the risk of accessing internal operating systems via the external information interface and networks. So as part of your preparation for the project, you need to investigate what platforms can be used and what risk analysis must be taken in implementation. 

 

Optional STOP for questions and activities: 

The following activities focus on macro-ethics. They address the wider ethical contexts of projects like the industrial data acquisition system. 

1. Activity: Explore different manufacturers and their approaches to safety for both machines and operators. 

2. Activity: Technical integration – Undertake a technical activity related to automation engineering and information engineering. 

3. Activity: Research what happens with the data collected by IIoT. Who can access this data and how can the data analysis module manipulate the data?  

4. Activity: Develop a risk management register, taking considerations of the findings from Activity 3 as well as the aspect of putting in place data security protocols and relevant training for SMT. 

5. Discussion/activity: Use information in the Ethical Risk Assessment guide to help students consider how ethical issues are related to the risks they have just identified. 

6. Discussion: In addition to cost-benefit analysis, how can the ethical factors be considered in designing the data analysis module? 

7. Activity: Debate the appropriateness of installing and using the system for the SMT. 

8. Discussion: What responsibilities do engineers have in developing these technologies? 

 

Dilemma – Part three – Security breach and legal responsibility: 

At the beginning of operation, the IIoT system with AI algorithms improved the efficiency of production lines by updating the parameters in robot operation and product recipes automatically. Recently, however, the efficiency degradation was observed, and after investigation, there were suspicions that the rules/data in AI algorithms have been subtly changed. Developers, contractors, operators, technicians and managers were all brought in to find out what’s going on. 

 

Optional STOP for questions and activities: 

1. Discussion: If there has been an illegal hack of the system, what might be the motive of cyber criminals?   

2. Discussion: What are the impacts on company business? How could the impact of cyber-attacks on businesses be minimised?

3. Discussion: How could threats that come from internal employees, vendors, contractors or partners be prevented?

4. Discussion: When a security breach happens, what are the legal responsibilities for developers, contractors, operators, technicians and managers?

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.

Learning and teaching notes: 

This case study considers not only the environmental impacts of a clean technology (the heat pump) but also the social and economic impacts on the end user. Heat pumps form an important part of the UK government’s net-zero plan. Our technical knowledge of heat pump performance can be combined with the practical aspects of implementing and using this technology. However, students need to weigh the potential carbon savings against the potential economic impact on the end user, and consider whether current policy incentivises consumers to move towards clean heating technologies.  

This case study offers students an opportunity to practise and improve their skills in making estimates and assumptions. It also enables students to learn and practise the fundamentals of energy pricing and link this to the increasing issue of fuel poverty. Fundamental thermodynamics concepts, such as the second law, can also be integrated into this study.  

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 six parts. If desired, a teacher can use the Summary and Part one in isolation, but Parts two to six develop and complicate the concepts presented in the Summary and Part one to provide for additional learning.

Summary – Heating systems and building requirements: 

You are an engineering consultant working for a commercial heat pump company. The company handles both the manufacture and installation of heat pumps. You have been called in by a county council to advise and support a project to decarbonise both new and existing housing stock. This includes changes to social housing (either directly under the remit of the council or by working in partnership with a local housing association) and also to private housing, encouraging homeowners and landlords to move towards net zero emissions. In particular, the council is interested in the installation of clean heating technologies with a focus on heat pumps, which it views as the most technologically-ready solution. Currently most heating systems rely on burning natural gas in a boiler to provide heat. By contrast, a heat-pump is a device that uses electricity to extract heat from the air or ground and transfer it to the home, avoiding direct emission of carbon dioxide.  

The council sets your first task of the project as assessing the feasibility of replacing the existing gas boiler systems with heat pumps in social housing. You are aware that there are multiple stakeholders involved in this process you need to consider, in addition to evaluating the suitability of the housing stock for heat pump installation.  

 

Optional STOP for questions and activities: 

1. Discussion: Why might the council have prioritised retrofitting the social housing stock with heat pumps as the first task of the project? How might business and ethical concerns affect this decision?  

2. Activity: Use stakeholder mapping to determine who are the main stakeholders in this project and what are their main priorities? In which areas will these stakeholders have agreements or disagreements? What might their values be, and how do those inform priorities?  

3. Discussion: What key information about the property is important for choosing a heating system? What does the word feasibility mean and how would you define it for this project? 

4. Activity: Research the Energy Performance Certificate (EPC):  what are the main factors that determine the energy performance of a building?  

5. Discussion: What do you consider to be an ‘acceptable’ EPC rating? Is the EPC rating a suitable measure of energy efficiency? Who should decide, and how should the rating be determined?  

 

Technical pre-reading for Part one: 

It is useful to introduce the thermodynamic principles on which heat pumps operate in order to better understand the advantages and limitations when applying this engineering technology in a real-world situation. A heat pump receives heat (from the air, ground, or water) and work (in the form of electricity to a compressor) and then outputs the heat to a hot reservoir (the building you are heating). We recommend covering: 

An online, open-source textbook that covers both topics is Applications of Thermodynamics – Heat Pumps & Refrigerators. 

 

Dilemma – Part one – Considering heat pump suitability: 

You have determined who the main stakeholders are and how to define the project feasibility. A previous investigation commissioned by the council into the existing housing stock, and one of the key drivers for them to initiate this project, has led them to believe that most properties will not require significant retrofitting to make them suitable for heat pump installation.  

 

Optional STOP for question and activities: 

1. Activity: Research how a conventional gas boiler central heating system works. How does a heat pump heating system differ? What heat pump technologies are available? What are the design considerations for installing a heat pump in an existing building? 

 

Dilemma – Part two – Inconsistencies: 

You spot some inconsistencies in the original investigation that appear to have been overlooked. On your own initiative, you decide to perform a more thorough investigation into the existing housing stock within the local authority. Your findings show that most of the dwellings were built before 1980 and less than half have an EPC rating of C or higher. The poor energy efficiency of the existing housing stock causes a potential conflict of interest for you: there are a significant number of properties that would require additional retrofitting to ensure they are suitable for heat pump installation. Revealing this information to the council at this early stage could cause them to pull out of the project entirely, causing your company to lose a significant client. You present these findings to your line manager who wants to suppress this information until the company has a formal contract in place with the council.  

 

Optional STOP for question and activities: 

1. Discussion: How should you respond to your line manager? Is there anyone else you can go to for advice? Do you have an obligation to reveal this information to your client (the council) when it is they who overlooked information and misinterpreted the original study? 

2. Activity: An example of a factor that causes a poor EPC rating is how quickly the property loses heat. A common method for significantly reducing heat loss in a home is to improve the insulation. Estimate the annual running cost of using an air-source heat pump in a poorly-insulated versus a well-insulated home to look at the potential financial impact for the tenant (example approach shown in the Appendix, Task A). 

3. Discussion: What recommendations would you make to the council to ensure the housing is heat-pump ready? Would your recommendation change for a new-build property? 

 

Dilemma – Part three – Impact of energy costs on the consumer: 

Your housing stock report was ultimately released to the council and they have decided to proceed, though for a more limited number of properties. The tenants of these dwellings are important stakeholders who are ultimately responsible for the energy costs of their properties. A fuel bill is made up of the wholesale cost of energy, network costs to transport it, operating costs, taxes, and green levies. Consumers pay per unit of energy used (called the unit cost) and also a daily fixed charge that covers the cost of delivering energy to a home regardless of the amount of energy used (called the standing charge). In the UK, currently the price of natural gas is the main driver behind the price of electricity; the unit price of electricity is typically three to four times the price of gas. 

Your next task is to consider if replacing the gas boiler in a property with a heat pump system will have a positive or negative effect on the running costs.  

 

Optional STOP for questions and activities: 

1. Activity: Estimate the annual running cost for a property when using a heat pump versus a natural gas boiler (see Appendix Task B for an example approach). 

2. Discussion: Energy prices are currently rising and have seen drastic changes in the UK over the past year. The lifetime of a new heat pump system is around 20 years. How would rising gas and electric prices affect the tenant? Does this impact the feasibility of using a gas boiler versus a heat pump? How can engineering knowledge and expertise help inform pricing policies? 

 

Dilemma – Part four – Tenants voice concerns: 

After a consultation, some of the current tenants whose homes are under consideration for heat pump installation have voiced concerns. The council is planning to install air-source heat pumps due to their reduced capital cost compared to a ground-source heat pump. The tenants are concerned that the heat pump will not significantly reduce their fuel bills in the winter months (when it is most needed) and instead could increase their bills if the unit price and standing charge for electricity continue to increase. They want a guarantee from the council that their energy bills will not be adversely affected. 

 

Optional STOP for questions and activities: 

1. Discussion: Why would air-source heat pumps be less effective in winter? What are the potential effects of increased energy bills on the tenants? How much input should the tenants have on the heating system in their rented property? 

2. Discussion: Do the council have any responsibility if the installation does result in an increased energy bill in the winter for their tenants? Do you and your company have any responsibility to the tenants?  

 

Dilemma – Part five – The council consultation: 

The council has hosted an open consultation for private homeowners within the area that you are involved in. They want to encourage owners of private dwellings to adopt low-carbon technologies and are interested in learning about the barriers faced and what they can do to encourage the adoption of low carbon-heating technologies. The ownership of houses in the local area is similar to the overall UK demographic: around 20% of dwellings are in the social sector (owned either by the local authority or a housing association), 65% are privately owned, and 15% are privately rented.  

 

Optional STOP for questions and activities: 

1. Activity: Estimate the lifetime cost of running an air-source heat pump and ground-source heat pump versus a natural gas boiler. Include the infrastructure costs associated with installation of the heating system (see Appendix Task C for an example approach). This can be extended to include the impact of increasing energy prices.  

2. Activity: Research the policies, grants, levies, and schemes available at local and national levels that aim to encourage uptake of net zero heating. 

3. Discussion: From your estimations and research, how suitable are the current schemes? What recommendations would you make to improve the uptake of zero carbon heating? 

 

Dilemma – Part six – Recommendations: 

Energy costs and legislation are important drivers for encouraging homeowners and landlords to adopt clean heating technologies. There is a need to weigh up potential cost savings with the capital cost associated with installing a new heat system. Local and national policies, grants, levies, and bursaries are examples of tools used to fund and support adoption of renewable technologies. Currently, an environmental and social obligations cost, known as the ‘green levies,’ are added to energy bills which contribute to a mixture of social and environmental energy policies (including, for example, renewable energy projects, discounts for low-income households, and energy efficiency improvements).  

Your final task is to think more broadly on encouraging the uptake of low-carbon heating systems in private dwellings (the majority of housing in the UK) and to make recommendations on how both councils locally and the government nationally can encourage uptake in order to reduce carbon emissions.  

 

Optional STOP for questions and activities: 

1. Discussion: In terms of green energy policy, where does the ethical responsibility lie –  with the consumer, the local government, or the national government?  

2. Discussion: Should the national Government set policies like the green levy that benefit the climate in the long-term but increase the cost of energy now?  

3. Discussion: As an employee of a private company, to what extent is the decarbonisation of the UK your problem? Do you or your company have a responsibility to become involved in policy? What are the advantages or disadvantages to yourself as an engineer?  

 

Appendix: 

The three tasks that follow are designed to encourage students to practise and improve their zeroth order approximation skills (for example a back of the envelope calculation). Many simplifying assumptions can be made but they should be justified.  

Task A: Impact of insulation 

Challenge: Estimate the annual running cost for an air-source heat pump in a poorly insulated home. Compare to a well-insulated home.  

Base assumptions around the heat pump system and the property being heated can be researched by the student as a task or given to them. In this example we assume:  

Example estimation: 

1. Estimate the overall heat loss for a poorly- and well-insulated property.

Note: heat loss is greater in the poorly insulated building.

 

 2. Calculate the work input for the heat pump.  

Assumption: heat pump matches the heat loss to maintain a consistent temperature.

 Note: a higher work input is required in the poorly insulated building to maintain a stable temperature.

 

3. Determine the work input over a year. 

Assumption: heat pump runs for 8 hours per day for 365 days.

 

4. Determine the running cost 

For an electricity unit price of 33.8 p per kWh.

 

Note: running cost is higher for the poorly insulated building due to the higher work input required to maintain temperature. 

 

Task B: Annual running cost estimation 

Challenge: Estimate the annual running cost for a property when using a heat pump versus a natural gas boiler.  

Base assumptions around the boiler system, heat pump system, and property can be researched by the student as a task or given to them. In this example we assume: 

Energy tariffs (correct at time of writing) for the domestic consumer including the energy price guarantee discount: 

Domestic energy tariffs 
Electric standing charge  51.0p per day 
Unit price of electricity  33.8p per kWh 
Gas standing charge  26.8p per kWh 
Unit price of gas  10.4p per kWh 

 

Example estimation: 

1. Calculate the annual power requirement for each case. 

Assumed heating requirement is 15,000 kWh for the year. 

2. Calculate the annual cost for each case: 

Note: the higher COP of the ground-source heat pump makes this the more favourable option (dependent on the fuel prices).  

 

Task C: Lifetime cost estimation  

Challenge: Estimate the total lifetime cost for a property when using a heat pump versus a natural gas boiler.  

Base assumptions around the boiler system, heat pump system, and property can be researched by the student as a task or given to them. In this example we assume: 

Energy tariffs (correct at time of writing) for the domestic consumer including the energy price guarantee discount: 

Domestic energy tariffs 
Electric standing charge  51.0p per day 
Unit price of electricity  33.8p per kWh 
Gas standing charge  26.8p per kWh 
Unit price of gas  10.4p per kWh 

 

1. Calculate the lifetime running cost for each case.

 

2. Calculate the total lifetime cost for each case.

Case enhancement: Water wars: managing competing water rights

Activity: Role-play the council meeting, with students playing different characters representing different perspectives.

Author: Cortney Holles (Colorado School of Mines, USA).

 

Overview:

This enhancement is for an activity found in the Dilemma Part two, Point 6 section: “Role-play the council meeting, with students playing different characters representing different perspectives.” 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.

 

Prompts for questions:

After discussing the case in class, and completing the stakeholder mapping activity (Dilemma Part one, Point 4 – repeated below) from the Water Wars case study, this lesson guides teachers through conducting a role-play of the council meeting scenario.

1. Discuss the stakeholder mapping activity: Who are all the characters in the scenario? What are their positions and perspectives? How can you use these perspectives to understand the complexities of the situation more fully?

2. To prepare for the council meeting role-play activity, assign students in advance to take on different stakeholder roles (randomly or purposefully), or let them self-assign based on their interests.  Roles can include any of the following:

Suggestions from Stakeholder mapping activity:

Additional stakeholders to consider:

3. Before the class session in which the role-play will occur, students should research their stakeholder to get a sense of their values and motivations in regard to the case. Where no information is available, students can imagine the experiences and perspectives of the stakeholder with the goal of articulating what the stakeholder values and what motivates them to come to the council meeting to be heard on this issue. Students should prepare some statements about the stakeholder position on the water use by DSS, what the stakeholder values, and what the stakeholder proposes the solution should be. Students assigned to be council members will prepare for the role-play by learning about the conflict and writing potential questions they would want to ask of the stakeholders representing different views on the conflict.

4. In class, students prepare to role-play the council meeting by first connecting with others in the same stakeholder role (if applicable – you may have few enough students to have only one student assigned to a stakeholder) and deciding who can speak (you may want to require each student to speak or ask that one person be nominated to speak on behalf of the stakeholder group).

5. As the session begins, remind students to jot down notes from the various perspectives’ positions so there can be a debrief conversation at the end.  Challenge students to consider their personal biases and position at the outset and reflect on those positions and biases at the end of the council meeting. If they were a lead member of the council, what solution would they propose or vote for?

6. As the Council Meeting begins, 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 students representing the Council members.  Council members will open the meeting with their description of the matter at hand between DSS and other local parties. They set the tone for the meeting with a call for feedback from the community members. The teacher can help the Council members call up the stakeholders in turn. Each stakeholder group will have a chance to state their argument, values, and reasons for or against DSS’ water use.  Each stakeholder will have an opportunity to suggest a proposed solution and Council members can engage in discussion with each stakeholder to clarify anything about their position that was unclear.

7. At the end of the meeting, the council members privately confer and then publicly vote on a resolution for the community.  All students, no matter their role, end the class by reflecting on the outcome and their original position on the case. Has anything shifted in their position or rationale after the council meeting? Why or why not?

8. The whole class could then engage in a discussion about the outcome of the council meeting. Teachers could focus on an analysis of how the process went, a discussion about the persuasiveness of different values and positions, and/or an exploration of the internal thinking students went through to arrive at their positions.
