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. The case study allows teachers the option to stop at multiple points for questions and/or activities, as desired.

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: Power-to-food technologies

Activity: An ethical evaluation of the technology and its impacts.

Author: Dr Fiona Truscott (UCL).

 

Overview:

This enhancement is for an activity found in the Dilemma Part one, Point 1 section of the case: “Identify different aspects of the production process where ethical concerns may arise, from production to delivery to consumption.” Below are 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.

In this group activity, students will act as consultants brought in by the Power to Food team to create an ethical evaluation of the technology and any impacts it may have throughout its lifetime. The aim here is for students to work together to discuss the potential ethical issues at each stage of the production process as well as thinking about how they might be addressed. Groups will need to do research, either in class or at home. Depending on the timeframe you may want to give them a starting point and some basic information found in the case study’s learning and teaching resources.

 

Suggested timeline:

 

Team briefing:

You are a team of consultants brought in by the company who has developed Power to Food technology. Before they go to market they want to understand the ethical issues that may arise from the technology and address them if possible. They want you to look at the process as a whole and identify any ethical issues that might come up. They also want to know how easy these issues might be to address and want you to suggest potential ways to address them. You will need to provide the company with a briefing on your findings.

 

Tools:

It’s useful to give teams some frameworks through which they can do an analysis of the production process. One of those is to discuss who is harmed by the process at each stage. This is harm in the widest possible sense: physical, environment, political, reputational etc. What or who could be impacted and how? Another framework is the values of the people or entities involved in the process: what are they trying to achieve or what do they want and are any of these in conflict? Topics such as sustainability and accessibility also have an ethical dimension, and using these as a lens can help students to look at the problem from a different viewpoint.

 

Prompts for questions:

These are questions that you can get students to answer in class or suggest that they cover in an assessment. This could also be information you give the team so that they can use it as a foundation.

 

Assessment:

This group activity lends itself to a few different assessment formats, depending on what fits with your programme and timeframe. The two key things to assess are whether students can understand and identify ethical issues across the whole Power to Food production process and whether they can discuss ways to address these issues and the complexities that can be involved in addressing these issues. These two things can be assessed separately; for example through a written report where teams discuss the potential issues and a presentation where they talk about how they might address these issues. Or one assessment can cover both topics. This can be a written report, a live or recorded presentation, a video, podcast or a poster. Teams being able to see other teams’ contributions is both a good way of getting them to discuss different viewpoints and makes for a fun session. You can get teams to present their final work or a draft to each other.

Depending on the timeframe, you may also want to build in some skills assessment too. The AAC&U’s VALUE rubrics are a great starting point for assessing skills and IPAC is a good tool for assessing teamwork via peer assessment.

 

Marking Criteria:

Good Average Poor
Understanding and identification of ethics issues across the whole Power to Food production process Has identified and understood context specific ethical issues across the production process. May have shown some understanding of how issues may impact on each other. Has identified and understood broad/general ethical issues around production processes but hasn’t linked much to the specific context of the case study. Some stages may be more detailed than others. Has not identified many or any ethical issues and seems to have not understood what we’re looking for.
Discussing ways to address these issues and the complexities that can be involved Has identified context specific ways to address the ethical issues raised and has understood the potential complexities of addressing those ethical issues. Has identified broad/general ways to address the ethical issues raised and made some reference to differing levels of complexity in addressing ethical issues. Has not identified many or any ways to address the ethical issues raised and seems to have not understood what we’re looking for.
Communication Very clear, engaging and easy to understand communication of the ethical issues involved and ways to address them. Right language level for the audience. Generally understandable but not clear in places or uses the wrong level of language for the audience (assumes too much or not enough prior knowledge). Difficult to understand the point being made either due to language used or disconnection to the point of the assessment or topic.

Case Enhancement: Choosing to install a smart meter

Activity: Technical integration – Practical investigation of electrical energy.

Author: Mr Neil Rogers (Independent Scholar).

 

Overview:

This enhancement is for an activity found in the Dilemma Part two, Point 1 section of the case: “Technical integration – Undertake an electrical engineering technical activity related to smart meters and the data that they collect.”

This activity involves practical tasks requiring the learner to measure parameters to enable electrical energy to be calculated in two different scenarios and then relate this to domestic energy consumption. This activity will give technical context to this case study as well as partly address two AHEP themes:

This activity is in three parts. To fully grasp the concept of electrical energy and truly contextualise what could be a remote and abstract concept to the learner, it is expected that all three parts should be completed (even though slight modifications to the equipment list are acceptable).

Learners are required to have basic (level 2) science knowledge as well as familiarity with the Multimeters and Power Supplies of the institution.

Learners have the opportunity to:

Teachers have the opportunity to:

 

Suggested pre-reading:

To prepare for these practical activities, teachers may want to explain, or assign students to pre-read articles relating to electrical circuit theory with respect to:

 

Learning and teaching resources:

 

Activity: Practical investigation of electrical energy:

Task A: Comparing the energy consumed by incandescent bulbs with LEDs.

1. Power in a circuit.

By connecting the bulbs and LEDs in turn to the PSU with a meter in series:

a. Compare the wattage of the two devices.

b. On interpretation of their data sheets compare their luminous intensities.

c. Equate the quantity of each device to achieve a similar luminous intensity of approximately 600 Lumens (a typical household bulb equivalent).

d. now equate the wattages required to achieve this luminous intensity for the two devices.

 

2. Energy = Power x Time.

The units used by the energy providers are kWh:

a. Assuming the devices are on for 6 hours/day and 365 days/year, calculate the energy consumption in kWh for the two devices.

b. Now calculate the comparative annual cost assuming 1 kWh = 27p ! (update rate).

 

3.  Wider implications.

a. Are there any cost-benefit considerations not covered?

b. How might your findings affect consumer behaviour in ways that could either negatively or positively impact sustainability?

c. Are there any ethical factors to be considered when choosing LED lightbulbs? For instance, you might investigate minerals and materials used for manufacturing and processing and how they are extracted, or end-of-life disposal issues, or fairness of costs (both relating to production and use).

 

Task B: Using a plug-in power meter.

1. Connect the power meter to a dishwasher or washing machine and run a short 15/30 minute cycle and record the energy used in kWh.

2. Connect the power meter to a ½ filled kettle and turn on, noting the instantaneous power (in watts) and the time taken. Then calculate the energy used and compare to the power meter.

3. Connect the power meter to the fan heater and measure the instantaneous power. Now calculate the daily energy consumption in kWh for a fan heater on for 6 hours/day.

4. Appreciation of consumption of electrical energy over a 24 hour period (in kWh) is key. What are the dangers in reading instantaneous energy readings from a smart meter?

 

Task C: Calculation of typical domestic electrical energy consumption.

1. Using the list of items in Appendix A, calculate the typical electrical energy usage/day for a typical household.

2. Now compare the electrical energy costs per day and per year for these three suppliers, considering how suppliers source their energy (i.e. renewable vs fossil fuels vs nuclear etc).

 

Standing charge cost / day Cost per kWh Cost / day Cost / year
A) 48p 28p
B) 45p 31p
C) 51p 27p

 

3. Does it matter that data is collected every 30 minutes by your energy supplier? What implications might changing the collection times have?

4. With reference to Sam growing marijuana in the case, how do you think this will show up in his energy bill?

 

Appendix A: Household electrical devices power consumption:

Typical power consumption of electrical devices on standby (in Watts).

Wi-Fi router 10
TV & set top box 20
Radios & alarms 10
Dishwasher  5
Washing machine  5
Cooker & heat-ring controls 10

Theme: Collaborating with industry for teaching and learning

Authors: Prof Lucy Rogers (RAEng Visiting Professor at Brunel University, London and freelance engineering consultant) and Petra Gratton (Associate Dean of Professional Development and Graduate Outcomes in the College of Engineering, Design and Physical Science at Brunel University London, and Lecturer in the Department of Mechanical and Aerospace Engineering)

Keywords: Industry, Interview, Video, Real Life, Engineers

Abstract: A number of short videos that can be re-used in teaching undergraduate modules in Engineering Business, instead of inviting guest presentations. The interview technique got each individual to talk about their life experiences and topics in engineering business that are often considered mundane (or challenging) for engineers, such as ethics, risks and regulation, project management, innovation, intellectual property, life-cycle assessment, finance and creativity. They also drew attention to their professional development.

 

Project outcomes

The outcomes of this project are a number of short videos that were used, and can be re-used, in teaching delivery of an undergraduate module in Engineering Business in the Department of Mechanical and Aerospace Engineering at Brunel University London instead of having guest presentations from invited speakers.  Lucy’s interview technique got the individuals featured in each film to talk about their life experiences and topics in engineering business that are often considered mundane (or challenging) for engineers, such as ethics, risks and regulation, project management, innovation, intellectual property, life-cycle assessment and finance; and drew attention to their professional development. 

The shorter videos were inspirational for students to make videos of themselves as part of the assessment of the module, which required them to carry out a personal professional reflection exercise and report upon what they had learned from the exercise in a simple 90-second video using their smartphone or laptop. 

Having used the videos with Brunel students, Lucy has made them available on her YouTube channel: Dr Lucy Rogers – YouTube. Each of the videos are listed in the following table:

Lessons learned and reflections

We learned that students generally engaged with the videos that were used.  Depending which virtual learning environment (VLE) was being used, using pre-recorded videos in synchronous online lectures presents various challenges.  To avoid any unplanned glitches, in future we know to use the pre-recorded videos as part of the teaching-delivery preparation (e.g. in a flipped classroom mode). 

As part of her legacy, Lucy is going to prepare a set of simple instructions on producing video interviews that can be carried out by both staff and students in future.

Theme: Collaborating with industry for teaching and learning, Graduate employability and recruitment

Author: James Ford (University College London)

Keywords: Civil Engineering Design, Timber Design, Industry, Collaboration

Abstract: A project, developed jointly by UCL and engineers from ARUP, allowed students to work on redesigning the fire damaged roof of the Notre Dame Cathedral. Industry expertise complemented academic experience in civil engineering design to create a topical, relevant and creative project for students. The project combined technical learning in timber design with broader considerations such as costs, health and safety, buildability and environmental impacts. Final presentations being made to engineering teams at ARUP offices also developed wider professional skills.

 

Background

Following the 2019 fire in the Notre Dame Cathedral, Civil Engineering Students at University College London (UCL) were tasked with designing a replacement. The project was delivered, in collaboration with engineers from ARUP, within a Design module in Year 2 of the programme. The project was run as a design competition with teams competing against one another. The project built on learning and design project experience built up during years 1 and 2 of the course.

The collaboration with ARUP is a long-standing partnership. UCL academics and ARUP engineers have worked on several design projects for students across all years of the Civil Engineering Programme.

The Brief

Instead of designing a direct replacement for the roof the client wanted to create a modern, eye-catching roof extension which houses a tourist space that overlooks the city. The roof had to be constructed on the existing piers so loading limits were provided. The brief recognised the climate emergency and a key criterion for evaluation was the sustainability aspects of the overall scheme. For this reason, it also stipulated that the primary roof and extension structure be, as far as practicable, made of engineered timber.

 

Figure 1. Image from the project brief indicating the potential building envelopes for the roof design

 

Given the location all entries had to produce schemes that were quick to build, cause minimal disruption to the local population, not negatively impact on tourism and, most importantly, be safe to construct.

Requirements

Teams (of 6) were required to propose a minimum of 2 initial concept designs with an appraisal of each and recommendation for 1 design to be taken forward.

The chosen design was developed to include:

Teams had to provide a 10xA3 page report, a set of structural calculations, 2xA3 drawings and a 10-minute presentation.

Figure 2. Connection detail drawing by group 9

 

Delivery

Course material was delivered over 4 sessions with a final session for presentations:

Session 1: Project introduction and scheme designing

Session 2: Timber design

Session 3: Construction and constructability

Session 4: Fire Engineering and sustainability

Session 5: Student Presentations

Sessions were co-designed and delivered by a UCL academic and engineers from ARUP. The sessions involved a mixture of elements incl. taught, tutorial and workshop time. ARUP engineers also created an optional evening workshop at their (nearby) office were groups or individuals could meet with a practicing engineer for some advice on their design.

These sessions built on learning from previous modules and projects.

Learning / Skills Development

The project aimed to develop skills and learning in the following areas:

Visiting the ARUP office and working with practicing engineers also enhanced student understanding of professional practice and standards.

Benefits of Collaborating

The biggest benefit to the collaboration was the reinforcement of design approaches and principles, already taught by academics, by practicing engineers. This adds further legitimacy to the approaches in the minds of the students and is evidenced through the application of these principles in student outputs.

 

Figure 3. Development of design concepts by group 12

 

The increased range in technical expertise that such a collaboration brings provides obvious benefit and the increased resource means more staff / student interaction time (there were workshops where it was possible to have one staff member working with every group at the same time).

Working with an aspirational partner (i.e. somewhere the students want to work as graduates) provides extra motivation to improve designs, to communicate them professionally and impress the team. Working and presenting in the offices of ARUP also helped to develop an understanding of professional behaviour.

Reflections and Feedback

Reflections and feedback from all staff involved was that the work produced was of a high quality. It was pleasing to see the level of creativity that the students applied in their designs. Feedback from students gathered through end of module review forms suggested that this was due to the level of support available which allowed them to develop more complex and creative designs fully.

Wider feedback from students in the module review was very positive about the project. They could see that it built on previous experiences from the course and enjoyed that the project was challenging and relevant to the real world. They also valued the experiences of working in a practicing design office and working with practicing engineers from ARUP. Several students posted positively about the project on their LinkedIn profiles, possibly suggesting a link between the project and employability in the minds of the students.

Topic: Alternative food production.

Engineering disciplines: Energy; Chemical engineering.

Ethical issues: Sustainability; Social responsibility.

Professional situations: Public health and safety; Personal/professional reputation; Falsifying or misconstruing data / finances; Communication.

Educational level: Advanced.

Educational aim: Practise ethical reasoning. Ethical reasoning applies critical analysis to specific events in order to evaluate, and respond, to problems in a fair and responsible way.

 

Learning and teaching notes:

This case involves an engineer navigating multiple demands on a work project. The engineer must evaluate trade-offs between social needs, technical specifications, financial limitations, environmental needs, legal requirements, and safety. Some of these factors have obvious ethical dimensions, and others are more ambiguous. The engineer must also navigate a professional scenario in which different stakeholders try to influence the resolution of the dilemma.

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.

Summary:

Power-to-X (P2X) describes a number of pathways for the transformation of electricity to alternative forms. This can be utilised for storing energy for later use, in order to balance periods of excesses and deficits resulting from the use of renewable energy technologies. It can also be used in applications that do not use electricity, such as through the transformation of electricity to hydrogen or other gases for industrial use.

One area that has seen significant development in recent years is power-to-food (PtF). This pathway results in CO2 being transformed, through chemical or biological processes powered by renewable energy, into food. One such process uses electrolysis and the Calvin cycle to create hydrocarbons from CO2, water and bacteria. The end result is a microbial protein, a substance that could be used in animal feed. Ultimately, the technology could produce a meat alternative suitable for human consumption, further reducing the carbon emissions produced by intensive animal farming.

 

Optional STOP for questions and activities: 

1. Activity: Identify the potential harms and risks of this technology, both objective and subjective. For example, could the shift of food production from soil to chemical industries concentrate power in the hands of a few? What public perceptions or cultural values might impact the acceptance or uptake of the technology? 

2. Discussion: Wider context – What social, technological, economic, environmental, political, or legal factors might need to be considered in order to implement this technology?

3. Activity: Research companies that are currently developing P2X technologies. Which industries and governments are promoting P2X? How successful have early projects been? What obstacles exist in upscaling?

4. Activity: Undertake a technical activity in the area of biochemical engineering related to the storing and transforming of renewable energy.

 

Dilemma – Part one:

You are the Chief Technical Officer at a company that has developed PtF technology that can convert CO2 to edible fatty acids (or triglycerides). The potential of CO2 capture is attractive to many stakeholders, but the combination of carbon reduction tied in with food production has generated positive media interest. The company also intends to establish its PtF facility near a major carbon polluter, that will reduce transport costs. However, some nearby residents are concerned about having a new industrial facility in their area, and have raised additional concerns about creating unsafe food.

As part of the process to commercialise this technology, you have been tasked with completing an ethical assessment. This includes an analysis of the technology’s short and long-term effects in a commercial application.

 

Optional STOP for questions and activities: 

1. Discussion and Activity: Identify different aspects of the production process where ethical concerns may arise, from production to delivery to consumption. Which ethical issues do you consider to be the most challenging to address?

2. Discussion: What cultural values might impact the ethical assessment? Does trust play a role in our ethical and consumption decisions? What internal logics / business goals might steer, or influence, the acceptance of various ethical considerations?

3. Discussion: Which areas of the ethical assessment might stakeholders be most interested in, or concerned about, and why?

4. Discussion: Does the choice of location for PtF facilities influence the ethical assessment? What problems could this PtF technology solve?

5. Discussion: What competing values or motivations might come into conflict in this scenario? What codes, standards, or authoritative bodies might be relevant to this? What is the role of ethics in technology development?

6. Activity: Assemble a bibliography of relevant professional codes, standards, and authorities.

7. Activity: Research the introduction of novel foods throughout history and / or engineering innovations in food production.

8. Activity: Write up the ethical assessment of the business case, and include findings from the previous questions and research.

 

Dilemma – Part two:

You deliver your ethical assessment to your manager. Shortly afterwards you are asked to edit the report to remove or downplay some ethical issues you have raised. The company leadership is worried that potential investors in an upcoming financing round may be dissuaded from investing in the company if you do not edit these sections.

 

Optional STOP for questions and activities: 

1. Discussion: Professional and ethical responsibilities – What are the ethical implications of editing or not editing the report? What consequences could this type of editing have? Think about stakeholders such as the company, potential investors and society.

2. Discussion: Wider considerations of business ethics – How would you recognise an ethical organisation? What are its characteristics? What is the role of ethics in business?

Topic: Smart meters for responsible everyday energy use.

Engineering disciplines: Electrical engineering

Ethical issues: Integrity, Transparency, Social responsibility, Respect for the environment, Respect for the law

Professional situations: Communication, Privacy, Sustainability

Educational level: Beginner

Educational aim: To encourage ethical motivation. Ethical motivation occurs when a person is moved by a moral judgement, or when a moral judgement is a spur to a course of action. 

 

Learning and teaching notes:

This case is an example of ‘everyday ethics’. A professional engineer must give advice to a friend about whether or not they should install a smart meter. It addresses issues of ethical and environmental responsibility as well as public policy, financial burdens and data privacy. The case helps to uncover values that underlie assumptions that people hold about the environment and its connection to human life and services. It also highlights the way that those values inform everyday decision-making.

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 three parts that build in complexity. If desired, a teacher can use Part one in isolation, but Part two and Part three develops and complicates the concepts presented in Part one in order to provide additional learning. The case allows teachers the opportunity to stop at various points to pose questions and/or set activities.

Summary – Part one:

Sam and Alex have been friends since childhood. As they have grown older, they have discovered that they hold very different political and social beliefs, but they never let these differences of opinion get in the way of a long and important friendship. In fact, they often test their own ideas against each other in bantering sessions, knowing that they are built on a foundation of respect.

Sam works as an accountant and Alex has become an environmental engineer. Perhaps naturally, Alex often asks Sam for financial advice, while Sam depends on Alex for expert information related to sustainability and the environment. One day, knowing that Alex is knowledgeable about the renewable energy industry and very conscious of the impact of energy use at home, Sam messages Alex to say he is getting pressure from his energy company to install a smart meter.

Sam has been told that smart metering is free, brings immediate benefits to customers by helping them to take control of their energy usage, and is a key enabler for the transition away from fossil fuels use and towards the delivery of net zero emissions by 2050. Smart meters give consumers near real-time information on energy use, and the associated cost, enabling them to better manage their energy use, save money and reduce emissions. A further benefit is that they could charge their electric car far more cheaply using a smart meter on an overnight tariff.

Yet Sam has also read that smart meters ‘go dumb’ if customers switch providers and, as a pre-payment customer, this option may not be available with a smart meter. In addition, Sam suspects that despite claims that the smart meter roll out is free, the charge is simply being passed on to customers through their energy bills instead. Alex tries to give Sam as much good information as possible, but the conversation ends with the decision unresolved.

 

Optional STOP for questions and activities: 

1. Discussion and activity: Personal values – We know that Sam and Alex have different ideas and opinions about many things. This probably stems from a difference in how they prioritise values. For instance, valuing transparency over efficiency, or sustainability over convenience. Using this values activity as a prompt, what personal values might be competing in this particular case?

2. Discussion and activity: Everyday ethics – Consider what values are involved in your everyday choices, decisions, and actions. Write a reflective essay on three events in the past week that, upon further analysis, have ethical components.

3. Discussion: Professional values – Does Alex, as an environmental engineer, have a responsibility to advocate installing smart meters? If so, does he have more responsibility than a non-engineer to advocate for this action? Why, or why not?

4. Discussion: Wider impact – Are there broader ethical issues at stake here?

5. Activity: Role-play a conversation between Sam and Alex that includes what advice should be given and what the response might be.

 

Dilemma – Part two:

After getting more technical information from Alex, Sam realises that, with a smart meter, data on the household’s energy usage would be collected every 30 minutes.  This is something they had not anticipated, and they ask a number of questions about the implications of this. Furthermore, while Sam has already compared tariffs and costs as the main way to choose the energy provider, Alex points out that different providers use different energy sources such as wind, gas, nuclear, coal, and solar. Sam is on a tight budget but Alex explains that the cheaper solution is not necessarily the most environmentally responsible choice. Sam is frustrated: now there is something else to consider besides whether or not to install the smart meter.

 

Optional STOP for questions and activities:  

1. Activity: Technical integration – Undertake an electrical engineering technical activity related to smart meters and the data that they collect.

2. Activity: Research what happens with the data collected by a smart meter. Who can access this data and how is privacy protected? How does this data inform progress towards the energy transition from fossil fuels?

3. Activity: Research different energy companies and their approach to responsible energy sourcing and use. How do these companies communicate that approach to the public? Which company would you recommend to your friend and why?

4. Activity: Cost-benefit analysis – Sometimes the ethical choice is the more expensive choice. How do you balance short- and long-term benefits in this case? When, if ever, would it be ethically right to choose energy from non-renewable sources? How would this choice differ if the context being considered was different? For example, students could think about responsible energy use in industrialised economies versus the developing world and energy justice.

 

Dilemma – Part three:

Following this exchange with Sam, Alex becomes aware that one of the main obstacles in energy transition concerns communication with the public. Ideally, Alex wants to persuade family and other friends to make more responsible choices; however, it is clear that there are many more factors involved than can be seen in one glance. This includes what kinds of pressure is put on consumers by companies and the government. Alex begins to reflect on how policy drives what engineers think and do, and joins a new government network on Engineering in Policy.  

Alex and Sam meet up a little while later, and Sam announces that yes, a smart meter has been installed. At first Alex is relieved, but then Sam lets it slip that they are planning to grow marijuana in their London home. Sam asks whether this spike in energy use will be picked up as abnormal by a smart meter and whether this would lead to them being found out.

 

Optional STOP for questions and activities:  

1. Discussion: Personal values – What are the ethics involved in trying to persuade others to make similar choices to you?

2. Discussion and activity: Legal responsibility – What should Alex say or do about Sam’s disclosure? Role-play a conversation between Sam and Alex.

3. Discussion: Professional responsibility – What role should engineers play in setting and developing public policy on energy?

4. Activity: Energy footprint – Research which industries use the most energy and, on a smaller scale, which home appliances use the most energy.
