Abstract: This case study deals with a collaboration between KCL and National Grid on a EPSRC project. The project deals with assessing the impact of renewable energy sources on the electricity grid. This assessment will be carried out by using a transmission grid model provided by National Grid and device models developed by KCL.
Topic of the case study
This case study deals with the development of advanced models to study the impact of renewable energy sources, and more in general, inverter-based devices, on the UK transmission grid. More specifically, this project focuses on the impacts in terms of voltage and current distortion. This topic is referred to as âpower qualityâ in the specialist literature.
Aims
This research was motivated by various reports presented in the technical literature in the last decade, where a general increase of harmonic levels has been observed. A similar trend has been reported in several countries, simultaneously to the installation of increasing levels of renewable energy sources and other inverter-based devices. These reports have created some concerns about harmonic management in the future, when more renewable energy sources will be in services. Ultimately, the project aims at forecasting harmonic levels in 2050, and at determining impact on the equipment, and possible mitigating solutions.
Collaborating parties
This case study involved the collaboration between the Department of engineering at Kingâs College London and National Grid UK.
Project set up
Power quality is a specialist area within power systems that deals with deviation of voltage and current waveforms from the nominal values, in terms of both amplitude and frequency. The academic PI worked for a few years in the power industry, with the aim of specialising in power quality and understanding the issues faced by the power industry, as well as the tools that are used to carry out power system studies. The industrial PI is an expert in the area of power quality and has been involved with many standardisation groups as well as professional organisation to help developing common tools to harmonise the approach to power quality. Therefore, the two PIs have a similar expertise and background that allowed them to discuss and define common areas of research. When looking to develop such a specialist project, it is very important that all parties involved have a common ground, so that it is possible to interact and work in the same direction.
Outcomes
The project is still not finished, however, some of the original objectives have been achieved:
A 2050 scenario has been developed, by using: transmission system model data provided by National Grid, device models developed through research and testing, and identification of future locations of renewable energy sources. Although the case is still under development, preliminary results indicate that harmonic levels are expected to increase, but they can be managed using existing design practice.
A distribution system model with harmonic injection has been developed and it is currently under discussion with the industrial partner. This model is needed by the industrial partner to be able to represent the presence of renewable energy sources on the power grid at lower voltage levels.
This was the first collaboration between the academic and the industrial PI, and was very positive and constructive for both parties. Therefore, the two collaborators now planning to continue this collaboration via other projects in the future.
Lessons learned, reflections, recommendations
In terms of technical developments, the collaboration has been very productive, as it allowed the exchange of information between industry and academia. Specifically, the industrial partner provided data and models that are used by power system engineer working at National Grid to carry out renewable integration studies. This information cannot be found in the literature as it is protected by NDAs. On the other side, the university provided expertise in developing models that can be used to represent specialist equipment, and that are needed to study the integration of renewable energy sources. Development of such models is time consuming, and the support of the university allowed faster development and testing.
COVID impacted the collaboration because, as part of the original project plan, placements in industry were to be carried out. However, ultimately they didnât take place. The industrial placements would have helped the model development to proceed faster as it would have allowed closer communication. The use of remote meetings mitigated the impact of COVID and still allowed the project to be carried out successfully. For any project of this type, it is very important to be able to work closely with the industrial partner and being able to meet regularly. Being in the same office allows to discuss more frequently, rather than waiting for formal meetings to be set.
For a technical project aiming at analysis a very-well defined problem, one recommendation is to find the technical experts within the company that can provide expertise. This may take some time in the initial stages, but at the end it will pay off as it will allow to carry out meaningful technical discussions.

Abstract: NMITE is a greenfield engineering-specialist HEI in Herefordshire which welcomed its first students in September 2021. Partnership is key to our growth, from both necessity and choice. Our MEng Integrated Engineering is infused with partners who facilitate a challenge-based learning pedagogy, and our Centre for Advanced Timber Technology (opening September 2022) works in national partnership to deliver a curriculum developed by â and for – the timber engineering industry. Alongside a rich educational offer, NMITEâs greenfield status brings with it the responsibility to contribute to civic and economic growth. We are a named partner in Western Power Distributionâs Social Contract as we pursue shared goals for regional development and reduced economic inequality. Key to our goals is our role in in Herefordâs Town Plan, leading an initiative called The Skills Foundry which will promote community engagement around individual skills, and with businesses in the changing nature of work.
NMITE is a greenfield HEI founded to make a difference to the people of Herefordshire and to its economy. Herefordshire is characterised by lower-than-average wages, lower-than-average skills, higher proportions of part-time work, a GVA gap of £1.75bn[1], and is categorised as a social mobility coldspot [2]. Into this context, NMITE was launched in 2021 without any antecedent or parent organisation, and with an engineering and technology focus whose graduates would help address the national shortfall of engineers.  We see ourselves as educators, educational innovators, a catalyst for upskilling, and agents for regional change.
An HEI founded in partnership
From NMITEâs earliest days, building strong relationships with partners has been a core part of our culture. NMITEâs first supporters were industry partners, a mixture of local SMEs and national and international companies with a regional presence, united by the need for access to a talent pipeline of engineering graduates. The urgency of this need was evidenced in the raising of over ÂŁ1M of seed funding, from a range of businesses and individuals. This early investment demonstrated to Government and other stakeholders that the concept of an engineering higher education institution in Hereford had industrial support. In turn, this unlocked significant Government funding which has subsequently been matched through donations and sponsorship to NMITE.
Over the last five years, the portfolio of partners has continued to grow. The nature of the support spans equipment, expertise and financial donations. Our Pioneer Fund raised money to support NMITEâs first students, with donations recognised through naming opportunities. For NMITE, this enabled us to offer universal bursaries to our students joining in our first two years of operation – a powerful tool in student recruitment, and with a longer-term outcome for those early investors in their ability to develop relationships with students, increase their brand awareness and achieve their own recruitment targets in the future.
Curriculum Partnerships
NMITE welcomed its first MEng students in September 2021, and this has provided new opportunities for industrial partnership in the curriculum. The MEng Integrated Engineering is a challenge-led pedagogy where learners work in teams to address real engineering challenges provided by an industrial (and occasionally community) partner. During the process, learners have direct contact with professionals to understand commercial pressures and engineering value, apply theoretical knowledge and develop professional capabilities.
In the sprint-based MEng, NMITE learners tackle around 20 different challenges in this way. Since September, our first students have helped re-engineer the material on a torque arm, designed and built a moisture sensor for a timber-framed house, visualised data from a geotechnical survey, and validated/optimised their own designs for a free-standing climbing structure. Students are already building their portfolio of work, and employers are building relationships with our student body.
Amplifying Innovation
Whilst NMITE is comfortable in its positioning as a teaching-focused HEI, we are mindful of the contribution we can make to the regional economy. NMITE has benefitted from LEP investment to support regional skills and productivity [3], and we have identified opportunities in advanced timber technology, automated manufacturing and skills for a changing future of work.
The Centre for Advanced Timber Technology (CATT) will open in September 2022 on Skylon Park, Herefordâs Enterprise Zone. Drawing on insight from a series of round table meetings with global and national businesses in timber, we came to understand that the UK timber industry needed to be much better connected, with more ambitious collaboration across the industry both vertically (seed to end product) and horizontally (between architects, engineers and construction managers, for example). In pursuing these aims we once again opted for a partnerships-based approach, forging close relationships with Edinburgh Napier University – internationally recognised for timber construction and wood science – and with TDUK â the timber industryâs central trade body. Founded in this way, CATT is firmly rooted in industrial need, actively engaged with industrial partners across the supply chain, and helps join up activity between Scotland, England and Wales.Â
CATTâs opening in 2022 will spearhead NMITEâs offer for part-time, work-based learners (including professionals, reskillers and degree apprentices) and provide a progressive curriculum for a sustainable built environment. In keeping with NMITEâs pedagogical principals, the CATTâs curriculum will be infused with a diverse portfolio of industrial partners who will provide challenges and context for the CATT curriculum. In future years, the Centre for Automated Manufacturing will provide educational options for comparable learners in the manufacturing industry.
Our initial research in establishing need in these areas pointed not only to skills shortages, but to technological capacity. Herefordshire has a very high proportion of SMEâs who report difficulties in horizon scanning new technologies, accessing demonstrations, attracting and retaining graduates with up-to-date knowledge. In this space, and an HEI can play a key role in amplifying innovation; activities to support this will be integral to NMITEâs work at Skylon Park.
The Changing Nature of Work
NMITE is active in two further projects that support the regional economy and social mobility, founded in the knowledge that todayâs school leavers will face very different career paths and job roles to those we have enjoyed. Automation, globalisation and AI are hugely disruptive trends that will change opportunities and demand new skills.
NMITEâs âHerefordshire Skills for the Futureâ project is funded by the European Social Fund and helps SMEs, micro-businesses and young people to develop and secure the skills needed to flourish in the economy of 2030. Activities include:
skills audits for SMEs and creation of bespoke action plans
early career leadership development courses and networking
upskilling in entre- and intrapreneurship capabilities
significant upscaling of high-quality work experience for school and college students and careers advice
NMITEâs Future Skills Hub is a central element of the Hereford Stronger Towns bid [4] to the Governmentâs Towns Fund, a flagship levelling-up vehicle. The overarching goal of the hub is to provide access to skills and improve employment opportunities for Herefordians, in the context of changing job roles and opportunities.
Conclusion
Our core mission of innovation in engineering education is enhanced by our civic commitment to regional growth and individual opportunity. From the outset, NMITE has been clear that to meet business demand for work-ready engineers, business must contribute meaningfully to their development. We aim to contribute to closing the gap in regional, national and global demand for engineers, but without that critical early investment from partners we would not have been in the position to establish the radical institution that NMITE is today, that remains so close to the original vision of the Founders.

Abstract: Greater Manchester (GM) has committed to carbon neutrality by 2038. There is a 97m tonnes carbon emission gap between solutions currently available and a net zero budget. To bridge this innovation gap under the leadership of the Greater Manchester Combined Authority the agency brings together: Bruntwood, Hitachi, MMU, UoM, GM Growth Company, SSE and UoS to support R&D and innovation initiatives focused on customer pull to enable rapid deployment of new and emerging technologies, services and business models to meet the challenge of GM becoming a carbon neutral city-region by 2038, drive skills development and deliver economic growth.
The need for an Energy Innovation Agency
The Mayor for Greater Manchester Combined Authority (GMCA) has committed the city region to carbon neutrality by 2038. An analysis of the implications of the Paris Climate Change Agreement for Greater Manchester (GM) (Figure 1) has identified that there is a 97m tonnes carbon emission gap between solutions currently available and the actions needed to reach net zero. We refer to this as the Innovation Gap.
Â

To bridge the GM innovation gap under the leadership of GMCA the agency brings together: Bruntwood, Hitachi, Manchester Metropolitan University, University of Manchester, SSE and University of Salford to support R&D and innovation initiatives focused on customer pull to enable rapid deployment of new and emerging technologies, services and business models (energy innovations) to meet the challenge of GM becoming a carbon neutral city-region by 2038, driving skills development and delivering economic growth.
Forming the Energy Innovation Agency
GMCA initially approached the cityâs three universities to seek advice on how their academic expertise could be harnessed to help bridge the innovation gap. This quickly led to discussions between each of the universities that identified a wide pool of complementary, and largely non-competitive, areas of research expertise that could address the gap (Figure 2).   Â
Figure 2 Research expertise by university partner – darker colour indicates a greater depth of expertise in the area.
It was also clear that the timescales needed to deliver city wide change would not fit within a traditional academic approach to research and knowledge transfer that required a public-private partnership.
At the core of this partnership approach are three key components.
Public sector influence and leadership across both city region and local authority levels that enables new ways of working to be demonstrated and quickly built into local plans, can influence national policy and regulation, and convene wider public involvement.
The business community, end-users and investors, in its widest sense, who have the need for change and can drive change by steering the development of the business and finance models that allow rapid large-scale adoption and deployment of innovation.
Academic sector able to drive the underpinning research, access to research and test facilities to validate novel innovations, TRL and IP, and develop the skilled workforce needed.
Using existing networks, a core team comprising GMCA, Bruntwood, Hitachi, MMU, UoM, SSE and UoS came together to develop the business plan for the agency and to jointly provide the funding for the first three-years of the operation of the agency.
Vision, Aims and Objectives
To accelerate the energy transition towards a carbon-neutral economy by bridging the energy innovation gap, increasing the deployment of innovative energy solutions in GM and beyond, to speed-up the reduction of carbon emissions.
Aims:
Innovation Exploitation: supporting and scaling the most promising decarbonised energy innovations to maximise the early adoption of effective carbon-neutral energy systems.
Decarbonisation: reducing Greater Manchesterâs carbon emissions from energy to meet our ambitious target to be a carbon-neutral city region by 2038
Rapid Commercialisation: rapid transition of carbon-neutral energy innovations to full-scale integration.
Investment: creating and promoting investment opportunities for carbon-neutral energy innovations and projects in the city region.
Objectives:
Position Greater Manchester as a global destination of choice for those looking to create and deploy innovative net-zero energy solutions.
Create a clear entry point, managed development, and validation pathway, for innovators to test, trial, and scale their most promising energy technologies and services in Greater Manchester.
Enhance the connection between industry and academia âpushâ and customer âpullâ, by putting innovative products, services, and projects in front of purchasers at the very earliest stage for advice and steer.
Provide a dedicated vehicle to bid for competitive funding and for industry to generate investment value, pooling the very best innovations to solve key decarbonisation challenges.
Link local investment to innovative products and projects, to enable rapid development and deployment where clear business cases are set out.
Direct alignment to local and national policy and strategy, ensuring project delivery intelligently informs policy and vice-versa.
Foster public confidence in new approaches and technologies, creating local skills and employment opportunities and improving access to cheaper, cleaner energy for all.
Scope
With a population of 2.8 million covering 1,277 km2 the ten metropolitan boroughs of GMCA comprises the second most populous urban area in the UK, outside of London. The scope and potential for the Energy Innovation Agency is huge.
Figure 3 GMCA Energy Transition Region showing local authority boundaries.
Establishing the GM-city region area as an Energy Transition Region will provide the opportunity to develop the scale of deployment necessary to go beyond small-scale demonstration projects and develop the supply chains that can be replicated as a blue-print elsewhere in urban environments across the UK and internationally.
Progress to date
Following the investment by the founding partners a management team has been established within GMCAâs subsidiary âThe Growth Companyâ. An independent board chaired by Peter Emery CEO ENWL has also been established.
The formal launch event will take place on 28th April 2022, at which a first challenge to the innovation community to bring forward solutions to decarbonise non-domestic buildings will be set.

Abstract: A partnership between the University of Glasgow, Fujitsu UK, Astroscale and Amazon Web Services was established in response to a UK Space Agency call on Active Debris Removal mission design. This is the process of de-orbiting space debris objects from low Earth orbit with a dedicated spacecraft. The consortium brought together different but complementary expertise and tools to develop an algorithm (using machine learning and quantum-based computing) to design multiple-debris removal missions, able to select feasible sequences of debris objects among millions of permutations, in a fraction of the time of previous methods, and of better performance in terms of time and propellant required.
Overview
Space and its services have become part of everyoneâs daily life, quietly. Things like mapping, geolocation, telecommunication services and weather forecast all depend on space assets. The continuous and increasing exploration and exploitation of space heavily depends on sustainability: defunct satellites and other spacecraft and launcher parts that became part of space debris population, or âjunkâ, increasing the threat of collision for current and future missions. There are 34,000 objects larger than 10 cm, and 130 million smaller than 1 cm, including non-operational satellites, upper stage rocket bodies, satellite parts, etc. Most of these objects are in the low Earth orbit region (below 1000 km), which is where most satellites operate.
Design of new satellites for demise prevents the creation of further debris. Active debris removal (ADR) aims dispose of debris objects that are currently in orbit. ADR actions require a âchaserâ spacecraft to grapple a ânon-cooperativeâ target, and transfer it to an orbit low enough that it will eventually de-orbit and burn in the atmosphere in a relatively short amount of time.
The idea
Many ADR missions would be required to make a substantial contribution in diminishing the debris population. The business challenge was to investigate how we could make space debris removal missions more commercially viable. This project investigated the feasibility, viability and design of removal and disposal of multiple debris objects using a single chaser spacecraft. The mission scenario involves a spacecraft that transfers to the orbit of one or more objects, captures it (or them), and then transfers to a lower orbit for release and disposal. At low altitude, the atmospheric drag will quickly cause the object to rapidly fall and burn in the atmosphere. In the meantime, the chaser spacecraft will transfer to another object (or set of objects) and continue the mission.
The problem
With million pieces of space junk, there are multiple trillions of permutations for ADR missions between these objects, that would need to be investigated, to efficiently remove even only a few of them. Since orbital transfers have no analytical closed-form solutions, an optimisation strategy must be used to find a solution to trajectory design problems, which is generally computationally demanding.
Our solution
The aim of this project was to make space debris removal missions more commercially viable, through a new solution that allows fast mission planning. First, an Artificial Neural Network (ANN) is trained to predict the cost of orbital transfer to and disposal of a range of debris objects quickly. Then, this information is used to plan a mission of four captures from candidate possible debris targets using Fujitsuâs quantum-inspired optimisation technology, called Digital Annealer (DA), by formulating the problem as a quadratic unconstrained binary optimisation. We used Astroscaleâs mission planning data and expertise, and run the algorithms on the Amazon Web Services (AWS) Sagemaker platform. For technical details on our approach, the reader is referred to the publications below.
Outcomes
In a test-scenario, we showed that our solution produced a 25% faster mission, using 18% less propellant when compared to an expertâs attempt to plan the mission using the same assumptions; this was found 170,000 times faster than current methods based on an expertâs work.
Partnership
The project involved the partnership of four institutions, with areas of contributions described in the following diagram:
We believe the key to the success of the partnership was the different, but complementary areas of expertise, tools offered, and contribution of each partner into the project. It may be easier to rely on existing network of contacts, often with similar areas of expertise. However, this project shows that the additional effort of creating a new partnership can have great benefits, that overcome the initial difficulties.
Project set up
An initial contact between Fujitsu and UofG defined the original idea of the project, combining the existing expertise on discrete optimisation (Fujitsu) and multi-body space missions (UofG). The team was strengthened by expertise in active space debris removal (Astroscale) and cloud computing (AWS). The project proposal was funded by the United Kingdom Space Agency (UKSA), for a duration of four months, from September 2020 to January 2021.
Due to the on-going global pandemic, the project was run entirely online, with weekly meetings on Microsoft Teams. Fujitsu, as team lead, was responsible for planning and scheduling of tasks, as well as integration of code and reporting.
Lessons learned and reflections
Reactivity in preparing a project proposal was fundamental for the project: The very first contact between the partners was made at the end of July 2020, the proposal was submitted in mid-August and the project officially kicked-off in September.
Given the short timeframe, it was important to conceive a project proposal that fit the scope of the funder, but also matches with available expertise and personnel. It was also critical to frame the business challenge in the proposal.
From the point of view of the academic team, and again given the short window between notification of successful application and start of the project, these factors were crucial for the success of the project:
Immediate availability of an internal candidate as nominated Research Assistant â there would have been no time to open a new position and recruit externally.
An excellent researcher was particularly important, as there was no time to account for potential errors in the methods and their implementation.
A candidate with experience aligned with the project was sought â there would have been no time to train new staff.
A PhD student in the research group was the best candidate for the project: at the cost of taking a leave-of-absence from the PhD studentship, the project constituted a unique experience with industrial collaboration, enriched their CV through a ground-breaking project, added a conference and a journal paper to their track record, and eventually opened new areas of investigation for the rest of the PhD studentship.
It would have been probably unthinkable â or at not very credible â to deliver a project with new partners remotely without any in-person meeting before the pandemic; however, this turned out to be an enabler for this project, allowing to maximise time on actual development and save on travel costs.

Abstract: The case study is interesting as it combines the engaging topics of smart materials and sports engineering, and showcases the release of a sports product. The work is underpinned by academic papers, include a teaching focus one detailing how materials have influenced tennis rackets dating back to the origins of the game. Effect of materials and design on the bending stiffness of tennis rackets: https://doi.org/10.1088/1361-6404/ac1146.

This case study is about the application of auxetic materials to sports equipment. Particularly, it is about the development of the first ever tennis racket to feature auxetic fibre-polymer composites [1]. In our work, we aim to combine the exciting fields of sport and advanced materials to engage people with science, technology, engineering, and maths (STEM). Indeed, our work is multi-disciplinary. Dr Mohr is the R&D Manager for PreDevelopement at HEAD and brings expertise in tennis racket engineering, Dr Allen and Professor Alderson are academics and bring respective expertise in sports engineering and smart materials.
Dr Allen has been researching the mechanics of sports equipment for many years, with a focus on tennis rackets [2]. One project involved characterising the properties of over 500 diverse rackets dating back to the origins of the game in the 1870s to the present day. The rackets were from various collections, including the Wimbledon Lawn Tennis Museum in London, and HEAD in Kennelbach Austria, where Dr Mohr works. The museum houses particularly old and rare rackets, whereas the collection at HEAD has a broad range of more modern designs. Initial work involved developing techniques for efficiently characterising many rackets [3]. Subsequent publications describe how a shift in construction materials – from wood to fibre-polymer composites – around the 1970s and 1980s led to lighter and stiffer rackets, with shorter handles and larger heads [4], [5]. Indeed, the application of new materials has driven the development of tennis rackets, and further advances are likely to come from developments in materials and manufacturing techniques.
Professor Alderson has been researching smart materials and structures for many years, with a focus on auxetic materials [6]. Auxetic materials have a negative Poissonâs ratio, which means that they fatten when stretched and become thinner when compressed. A negative Poissonâs ratio can enhance other properties, including vibration damping. Dr Allen and Professor Alderson have been working together to apply auxetic materials to sports equipment [7]. Dr Allen discussed this work on auxetic materials with Dr Mohr, and this led to the collaboration between the three parties that resulted in the new racket design [1].
Auxetic fibre-polymer composites were particularly appealing to Dr Mohr for application in tennis rackets, as they can be made using conventional fibres and resins, by simply arranging the fibres in specific orientations [8]. Following a visit to HEAD, where he was able to see the prototyping facilities, Professor Alderson developed various auxetic fibre-polymer composites, using the materials already being used by HEAD to make rackets. HEAD then developed prototype rackets incorporating these auxetic fibre-polymer composites at their research and development facility in Kennelbach. The racket designs were further developed and refined through testing, both in the laboratory and on the tennis court with players providing feedback. Â
The first tennis racket with auxetic fibre composites was released in late 2021, in the form of the HEAD Prestige (Figure 1a). The Prestige was followed by the release of a new racket silo (collection) in early 2022 in the form of the Boom (Figure 1b). Drs Mohr and Allen and Professor Alderson are now exploring options for further applying auxetic materials to tennis rackets. Dr Allenâs teaching case study on the historical development of the tennis racket [4] has been enriched by including the story behind the development of the new auxetic fibre-polymer composite rackets [1]. He also includes discussion of emerging topics in the case study that could be applied to tennis rackets, such as more automated manufacturing techniques like additive manufacturing, and more environmentally friendly materials, like natural fibres and resins [5]. We hope that the new tennis rackets will raise awareness of auxetic materials amongst the public, and the case study will help inspire others to use topics like sports engineering and advanced materials to support their STEM teaching and public engagement.

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:
Full structural design; Calculations to Eurocodes, load path diagrams, member sizing, connection design, explanation of structural choices.
Buildability (cost breakdown, site logistics, consideration of context)
Health and Safety risks, impacts on design and control measures
Construction sequence
Sustainability summary inc. embodied carbon calculations
Teams had to provide a 10xA3 page report, a set of structural calculations, 2xA3 drawings and a 10-minute presentation.

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:
Technical skills relating to structural design using timber, embodied energy calculations, drawing and H&S risk assessment.
Design skills relating to consideration of the site, its context and the need, creativity and assessing ideas, consideration and overlapping of numerous disciplines, design iteration and improvement.
Professional skills in relation to communicating with clients, producing reports to a professional standard, presenting a project, working in teams, organising resources, etc.
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.

Abstract: The University of the West of England (UWE Bristol) has declared a Climate and Ecological Emergency, along with all regional councils in the West of England. In order to meet the regional goal of Net-Zero by 2030, sustainability education has now been embedded through all levels of the Engineering Curriculum. Current modules incorporate education for Sustainable Development Goals alongside citizen engagement challenges, where engineers find solutions to real-life problems. All undergraduate engineers also take part in immersive project weeks to develop problem-based learning around the Engineers without Borders international challenges.
Engineering Education for Sustainable Development
The environmental and health impacts of climate change and biodiversity loss are being felt around the world, from record high temperatures, drought, wildfires, extreme flooding, and human health issues (Ripple et al., 2020). The Intergovernmental Panel on Climate Change reports that urgent action is required to mitigate catastrophic impacts for billions of people globally (IPCC, 2022). The UK Government has pledged to reach net zero emissions by 2050, with a 78% drop in emissions by 2035 (UK Government, 2021). Following IPCC guidance, regional councils such as Bristol City Council and the West of England Combined Authority, have pledged to reach Net Zero at an earlier date of 2030 (Bristol City Council, 2019). In parallel, UWE Bristol has embedded this target within its strategic plan (UWE Bristol, 2019), and also leads the Environmental Association for Universities and Colleges (EAUC), an Alliance for Sustainability Leadership in Education (UWE Bristol, 2021b). All UWE Bristol programmes are expected to embed the UN Sustainable Development Goals (SDGs) within curricula (UN Department of Economic and Social Affairs, 2021), so that higher education degrees prepare graduates for working sustainably (Gough, 2021).
Bourn and Neal (2008) draw the link between global sustainability issues and engineering, with the potential to tackle complex sustainability challenges such as climate change, resource limitations, and extreme poverty. The SDGs are therefore particularly relevant to engineers, showing the connections between social, environmental, and economic actions needed to ensure humanitarian development, whilst also staying within planetary boundaries to support life on earth (Ramirez-Mendoza et al., 2020). The engineering sector is thus obligated to achieve global emissions targets, with the work of engineers being essential to enable the societal and technological change to reach net zero carbon emissions (Fogg-Rogers, L., Richardson, D., Bakthavatchaalam, V., Yeomans et al., 2021).
Systems thinking and solution-finding are critical engineering habits of mind (Lucas et al., 2014), and so introducing genuine sustainability problems provides a solid foregrounding for Education for Sustainable Development (ESD) in engineering. Indeed, consideration for the environment, health, safety, and social wellbeing are enshrined in the UK Specification for Professional Engineers (UK SPEC) (Engineering Council, 2021). âReal-worldâ problems can therefore inspire and motivate learners (Loyens et al., 2015), while the use of group projects is considered to facilitate collaborative learning (Kokotsaki et al., 2016). This aligns with recommendations for creating sustainability-literate graduates published by the Higher Education Academy (HEA) and the UK Quality Assurance Agency for Higher Education (QAA and Advance HE, 2021) which emphasise the need for graduates to: (1) understand what the concept of environmental stewardship means for their discipline and their professional and personal lives; (2) think about issues of social justice, ethics and wellbeing, and how these relate to ecological and economic factors; and (3) develop a future-facing outlook by learning to think about the consequences of actions, and how systems and societies can be adapted to ensure sustainable futures (QAA & HEA, 2014). These competencies are difficult to teach, and instead need to developed by the learners themselves based on experience and reflection, through a student-centred, interdisciplinary, team-teaching design (Lamere et al., 2021). Â
The need for engineers to learn about the SDGs and a zero carbon future is therefore necessary and urgent, to ensure that graduates are equipped with the skills needed to address the complex challenges facing the 21st Century. Lamere et al., (2021)describe how the introduction of sustainability education within the engineering curriculum is typically initiated by individual academics (early adopters) introducing elements of sustainability content within their own course modules. Full curricula refresh in the UWE Bristol engineering curricula from 2018-2020 enabled a more programmatic approach, with inter-module connections being developed, alongside inter-year progression of topics and skills.
This case study explores how UWE Bristol achieved this curriculum change throughout all programmes and created inter-connected project weeks in partnership with regional stakeholders and industry.Â
Case Study Methods – Embedding education for sustainable development
The first stage of the curricula transformation was to assess current modules against UK SPEC professional requirements, alongside SDG relevant topics. A departmental-wide mixed methods survey was designed to assess which SDGs were already incorporated, and which teaching methods were being utilized. The survey was emailed out to all staff in 2020, with 27 module leaders responding to highlight pedagogy in 60 modules, covering the engineering topics of: Aerospace; Mechanical and Automotive; Electrical, Electronic, and Robotics; Maths and Statistics; and Engineering Competency.
Two sub-themes were identified: âDirectâ and âIndirectâ embedding of SDGs; direct being where the engineering designs explicitly reference the SDGs as providing social or environmental solutions, and indirect being where the SDGs are achieved through engineering education e.g. quality education and gender equality. Direct inclusion of the SDGs tended to focus on reducing energy consumption, and reducing weight and waste, such as through improving the efficiency of the machines/designs. Mitigating the impact of climate change through optimal use of energy was also mentioned. The usage of lifecycle analysis was implemented in several courses, especially for composite materials and their recycling. The full analysis of the spread of the SDGs and their incorporation within different degree programmes can seen in Figure 1.
Figure 1 Number of Engineering Modules in which SDGs are Embedded
Project-based learning for civic engagement in engineering
Following this mapping process, the modules were reorganized to produce a holistic development of knowledge and skills across programmes, starting from the first year to the final year of the degree programmes. This Integrated Learning Framework was approved by relevant Professional Bodies and has been rolled out annually since 2020, as new learners enter the refreshed degree programmes at UWE Bristol. The core modules covering SDG concepts explicitly are Engineering Practice 1 and 2 (at Level 1 and 2 of the undergraduate degree programme) and âEngineering for Societyâ (at Level 3 of the undergraduate degree programme and Masters Level). These modules utilise civic engagement with real-world industry problems, and service learning through engagement with industry, schools, and community groups (Fogg-Rogers et al., 2017).
As well as the module redevelopment, a Project-Based Learning approach has been adopted at department level, with the introduction of dedicated Project Weeks to enable cross-curricula and collaborative working. The Project Weeks draw on the Engineering for People Design Challenge (Engineers without Borders, 2021), which present global scenarios to provide university students with âthe opportunity to learn and practice the ethical, environmental, social and cultural aspects of engineering designâ. Critically, the challenges encourage universities to develop partnerships with regional stakeholders and industry, to provide more context for real-world problems and to enable local service learning and community action (Fogg-Rogers et al., 2017).
A collaboration with the innovation company NewIcon enabled the development of a âdesign thinkingâ booklet which guides students through the design cycle, in order to develop solutions for the Project Week scenarios (UWE Bristol, 2021a). Furthermore, a partnership with the initiative for Digital Engineering Technology and Innovation (DETI) has enabled students to take part in the Inspire outreach programme (Fogg-Rogers & Laggan, 2022), which brings together STEM Ambassadors and schools to learn about engineering through sustainability focussed activities. The DETI programme is delivered by the National Composites Centre, Centre for Modelling and Simulation, Digital Catapult, UWE Bristol, University of Bristol, and University of Bath, with further industry partners including Airbus, GKN Aerospace, Rolls-Royce, and Siemens (DETI, 2021). Industry speakers have contributed to lectures, and regional examples of current real-world problems have been incorporated into assignments and reports, touching on a wide range of sustainability and ethical issues.
Reflections and recommendations for future engineering sustainability education
Students have been surveyed through module feedback surveys, and the project-based learning approach is viewed very positively. Students commented that they enjoyed working on âreal-world projectsâ where they can make a difference locally or globally. However, findings from surveys indicate that students were more inclined towards sustainability topics that were relevant to their subject discipline. For instance, Aerospace Engineering students tended to prefer topics relevant to Aerospace Engineering. A survey of USA engineering students by Wilson (2019) also indicates a link between studentsâ study discipline and their predilection for certain sustainability topics. This suggests that for sustainability education to be effective, the content coverage should be aligned, or better still, integrated, with the topics that form part of the studentsâ disciplinary studies.
The integration of sustainable development throughout the curricula has been supported at institutional level, and this has been critical for the widescale roll out. An institution-wide Knowledge Exchange for Sustainability Education (KESE) was created to support staff by providing a platform of knowledge sharing. Within the department, Staff Away days were used to hold sustainability workshops for staff to discuss ESD and the topics of interest to students. Â In the initial phase of the mapping exercise, a lack of common understanding amongst staff about ESD in engineering was noted, including what it should include, and whether it is necessary for student engineers to learn about it. During the Integrated Learning Framework development, and possibly alongside growing global awareness of climate change, there has been more acceptance of ESD as an essential part of the engineering curriculum amongst staff and students. Another challenge has been the allocation of teaching workload for sustainability integration. In the initial phases, a small number of committed academics had to put in a lot of time, effort, and dedication to push through with ESD integration. There is now wider support by module leaders and tutors, who all feel capable of delivering some aspects of ESD, which eases the workload.
This case study outlines several methods for integrating ESD within engineering, alongside developing partnership working for regionally relevant real-world project-based learning. A recent study of UK higher education institutions suggests that only a handful of institutions have implemented ESD into their curricula in a systemic manner (Fiselier et al., 2018), which suggests many engineering institutions still need support in this area. However, we believe that the engineering profession has a crucial role to play in ESD alongside climate education and action, particularly to develop graduate engineers with the skills required to work upon 21st Century global challenges. To achieve net zero and a low carbon global economy, everything we make and use will need to be completely re-imagined and re-engineered, which will require close collaboration between academia, industry, and the community. We hope that other engineering educators feel empowered by this case study to act with the required urgency to speed up the global transition to carbon neutrality.

Abstract: The New Model Institute for Technology and Engineering, Edinburgh Napier University and Timber Development UK are working with external stakeholders to enable an educational system that will provide comprehensive training in modern methods of timber construction. A Timber Technology Engineering and Design (TED) competency framework has been derived and a UK wide student design competition will run in the 1st quarter of 2022 as part of the process to curate the learner content and enable this alternative approach to upskilling. The EPC will gain an understanding of this alternative approach to creating an educational model by means of industry engagement. This new approach has been made possible via establishing a collaborative framework and leveraging available funding streams via the partners. This will be showcased as a methodology for others to apply to their own contexts as well as offer opportunity for knowledge and value exchange.
Introduction
Edinburgh Napier University (ENU), The New Model Institute for Technology and Engineering (NMITE) and Timber Development UK (TDUK) are working with external stakeholders to enable an educational system (Figure 1) that will provide comprehensive training in modern methods of timber construction. This case study presents an alternative approach to creating this Timber Technology Engineering and Design (TED) educational model by means of industry engagement and pilot learning experiences. This new approach has been made possible by establishing a collaborative framework and leveraging available funding streams via the partners.
Figure 1 â Approach to enabling Timber TED Educational System.
Project Aims
The aim of establishing Timber TED is to provide built environment students and professionals with a comprehensive suite of online credit bearing flexible training modules to upskill in modern timber construction techniques. To align the modules with industry need the learning content is to be underpinned by a competency framework identifying the evidence-based technical knowledge and meta skills needed to deliver construction better, faster and greener. The training modules are to be delivered in a blended manner with educational content hosted online and learners assessed by âlearning by doingâ activities that stimulate critical thinking and prepare the students for work in practice (Jones, 2007).
Uniting industry education and training resources through one course, Timber TED will support learners and employers to harness the new knowledge and skills required to meet the increasing demand for modern timber construction approaches that meet increasingly stringent quality and environmental performance requirements.
The final product will be a recognised, accredited qualification with a bespoke digital assessment tool, suitable for further and higher education as well as employers delivering in-house training, by complementing and enhancing existing CPD, built environment degrees and apprenticeships.
The Need of a Collaborative Approach
ENU is the project lead for the Housing Construction & Infrastructure (HCI) Skills Gateway part of the Edinburgh & Southeast Scotland City Region Deal and is funded by the UK and Scottish Governments. Funding from this was secured to develop a competency framework for Timber TED given the regional need for upskilling towards net zero carbon housing delivery utilising low carbon construction approaches and augmented with addition funding via the VocTech Seed Fund 2021. With the built environment responsible for 39% of all global carbon emissions, meeting Scotlandâs ambitious target of net zero by 2045 requires the adoption of new building approaches and technologies led by a modern, highly skilled construction workforce. Further to this ENU is partnering with NMITE to establish the Centre for Advanced Timber Technology (CATT) given the broader UK wide need. Notably England alone needs up to 345,000 new low carbon affordable homes annually to meet demand but is building less than a third of this (Miles and Whitehouse, 2013). The educational approach of NMITE is to apply a student-centric learning methodology with a curriculum fuelled by real-world challenges, meaning that the approach will be distinctive in the marketplace and will attract a different sort of engineering learner. This academic partnership was further triangulated with TDUK (merged organisation of TRADA and Timber Trades Federation) for UK wide industry engagement. The partnership approach resulted in the findings of the Timber TED competency framework and alternative pedagogical approach of NMITE informing the TDUK University Design Challenge 2022 project whereby inter-disciplinary design teams of 4â8 members, are invited to design an exemplary community building that produces more energy than it consumes â for Southside in Hereford. The TDUK University Design challenge would therefore pilot the approach prior to developing the full Timber TED educational programme facilitating the development of educational content via a webinar series of industry experts.
The Role of the Collaborators
The project delivery team of ENU, NMITE and TDUK are working collaboratively with a stakeholder group that represents the sector and includes Structural Timber Association, Swedish Wood, Construction Scotland Innovation Centre, Truss Rafter Association and TRADA. These stakeholders provide project guidance and are contributing in-kind support in the form of knowledge content, access to facilities and utilisation of software as appropriate.
Harlow Consultants were commission to develop the competency framework (Figure 1) via an industry working group selected to be representative of the timber supply chain from seed to building. This included for example engineered timber manufacturers, engineers, architects, offsite manufacturers and main contractors.
Figure 2 â Core and Cross-disciplinary high level competency requirements
The Southside Hereford: University Design Challenge (Figure 3) has a client group of two highly energised established community organisations Growing Local CIC and Belmont Wanderers CIC, and NMITE, all of whom share a common goal to improve the future health, well-being, life-chances and employment skillset of the people of South Wye and Hereford. Passivhaus Trust are also a project partner providing support towards the curation of the webinar series and use of their Passivhaus Planning software.
Figure 3 â TDUK, ENU, NMITE and Passivhaus Trust University Design Challenge
Outcomes, Lessons Learned and Available Outputs
The competency framework has been finalised and is currently being put forward for review by the professional institutions including but not limited to the ICE, IStructE, CIAT and CIOB. A series of pilot learning experiences have been trialled in advance of the UK wide design challenge to demonstrate the educational approach including a Passivhaus Ice Box challenge. The ice box challenge culminated in a public installation in Glasgow (Figure 4) presented by student teams acting as a visual demonstration highlighting the benefits of adopting a simple efficiency-first approach to buildings to reduce energy demands. The Timber TED competency framework has been used to inform the educational webinar series of the UK wide student design competition running in the 1st quarter of 2022. The webinar content collated will ultimately be used within the full Timber TED credit bearing educational programme for the upskilling of future built environment professionals.

The following are the key lessons learned:
Collaboration is key to maximising available resources enabling ambitious programmes of work for upskilling utilising alternative educational approaches to be realised.
Challenge based learning engages students and modern digital tools foster collaboration allowing multi-disciplinary teams to form consisting of students from different Universities. Â
Going forward the approach requires to be captured and aligned with learning outcomes for assessment and accreditation purposes such that it can become University credit bearing.

Topic: Data centresâ impact on sustainable water resources.
Professional situations: Law or policy, Communication, Integrity.
Educational level: Intermediate.
Educational aim: Practise ethical judgement. Ethical Judgment is the activity of thinking about whether something has a moral attribute. Judgments involve reaching moral decisions and providing the rationale for those decisions.
Â
Learning and teaching notes:
This case involves a situation where environmental damage may be occurring despite the mechanism causing this damage being permissible by law. The engineer at this centre of the case is to represent the company that is responsible for the potential damage, at a council meeting. It requires the engineer to weigh up various harms and goods, and make a decision that could seriously impact their own job or career. There is also a section at the end of this case study that contains technical information providing further details about the water cooling of ICT equipment.
This case study addresses two of AHEP 4âs 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 4here 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.
Students have the opportunity to:
apply their ethical judgement to a case study relating to environmental sustainability;
judge the societal impact of a technical solution to a complex problem;
identify and analyse objective and subjective risk;
consider the concept of consensus;
communicate the risks and judgements to technical and non-technical audiences.
Teachers have the opportunity to:
introduce environmental ethics concepts related to water;
highlight the components and processes of risk analysis;
integrate technical content related to heat transfer and flow;
informally evaluate studentsâ critical thinking and communication skills.
The company Data Storage Solutions (DSS) has built a large data centre on land that was historically used for agriculture and owned by a farming operation. DSS was incorporated as a subsidiary of the farming company so that it could retain the water rights that were attached to the property. This ensured access to the large amount of water needed to cool their servers. This centre manages data from a variety of sources including the local hospital and university.
When the property was used as a farm, the farming operation never used its full allocation of water. Now, the data centre always uses the maximum amount legally allotted to it. For the rainy half of the year, this isnât a problem. However, in more arid months, the nearby river almost runs dry, resulting in large volumes of fish dying. Other farmers in the area have complained that the water level in their wells has dropped, making irrigation much more expensive and challenging.
Â
Dilemma – Part one:
You are a civil engineer working for DSS and have been requested by your boss to represent the company at a forthcoming local council meeting where the issue will be discussed. Your employer is sending you to justify the companyâs actions and defend them against accusations of causing an environmental hazard in the local area which is reducing the water table for farmers and affecting local biodiversity. Your boss has told you that DSS has a right to the water and that it does not intend to change its behaviour. This meeting promises to be a contentious one as the local Green party and farmersâ union have indicated that they will be challenging the companyâs water usage. How will you prepare for the meeting?
Â
Optional STOP for questions and activities:Â
1. Discussion: Personal values – What is your initial position on the issue? Do you see anything wrong with DSSâs water use? Why, or why not?
2. Discussion: Professional responsibilities – What ethical principles and codes of conduct are relevant to this situation?
3. Activity: Define and identify the relevant data you should compile to take to the meeting. What information do you need in order to be prepared?
4. Activity: Stakeholder mapping – 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? Examples include:
Data Storage Solutions
Farmersâ union
Local Green party
Local council
Member of the public
Stakeholders who use DSSâs data storage services (such as the local hospital and schools)
Non-human stakeholders – for example, the fish, birds and insects.
5. Activity: Undertake a technical activity such as civil and / or electronic engineering related to the measurement of stream flow and calculating data centre cooling needs.
Â
Dilemma – Part two:
As you prepare for the meeting, you reflect on several competing issues. For instance, you are an employee of DSS and have a responsibility to represent its interests, but can see that the companyâs actions are environmentally harmful. You appreciate that the data centre is vital for the local community, including the safe running of schools and hospitals, and that its operation requires sufficient water for cooling. Your boss has told you that you must not admit responsibility for any environmental damage or biodiversity loss. You also happen to know that a new green battery plant is planning to open nearby that will create more data demand and has the potential to further increase DSSâs water use. You know that obtaining water from other sources will be costly to DSS and may not be practically possible, let alone commercially viable. What course of action will you pursue?

Optional STOP for questions and activities:Â
1. Activity: Debate what course of action you should take. Should you take the company line despite knowing about the environmental impacts? Should you risk your reputation or career? What responsibilities do you have to fellow employees, the community, and the environment?
2. Activity: Risk analysis – What are the short- and long- term burdens and benefits of each course of action? Should environmental concerns outweigh others? Is there a difference between the environment locally and globally?
3. Activity and discussion: Read Sandra Postelâs case for a Water Ethic, and consider New Zealandâs recent legislation that gives a rainforest the same rights as a human. With this in mind, does the stream have a right to thrive? Do the fish have a right to a sustainable environment? Are humans ultimately at risk here, or just the environment? Does that answer change your decision? Why?
4. Activity: Prepare a statement for the council meeting. What will you argue?
You could take the company line and refuse to consider any compromise. After all, you have the legal right to the water.
You could take the environmentalistsâ side and go against your boss, admitting that the company is aware of the environmental damage, but that they refuse to do anything about it.
You could work up a proposal for obtaining the water from a different source, or alternative technical solutions, despite not having the backing of your boss.
Are there other alternatives available to you?
5. Activity: The students should interrogate the pros and cons of each possible course of action including the ethical, the practical, the cost, the local relationship and the reputational damage implications. They should decide on their own preferred course of action and explain why the balance of pros and cons is preferable to other options.The students may wish to consider this from other perspectives, such as:
What actions are available to individuals at each level of hierarchy in DSS â for example, a junior engineer compared to a senior manager?
What would the best outcome be if the business or cost considerations were of no consequence?
What course of action would be taken if different perspectives were taken as the priority â for example, if the environmental perspective were the main priority what action would be taken, compared with action taken if the cost to the local economy were the main priority?
What are the wider implications of data storage on the environment and how can these be mitigated?
What could be other direct and indirect benefits of data centres, other than being a place to house data â for example, is there an opportunity for the waste heat from DSS to become a benefit? (Use theThe city where the internet warms peopleâs homes article.)
What are the possible solutions open to you?
Are there any short-term solutions versus longer-term solutions?
7. Activity: Allow students to reflect on how this case study has enabled them to see the situation from different angles, and whether this has helped them to understand the ethical concerns and come to an acceptable conclusion.

Annex – Accompanying technical information:
ICT equipment generates heat and so most devices must have a mechanism to manage their temperature. Drawing cool air over hot metal transfers heat energy to that air, which is then pushed out into the environment. This works because the computer temperature is usually higher than the surrounding air. There are several different mechanisms for data centre cooling, but the general approach involves chillers reducing air temperature by cooling water â typically to 7â10â°C, which is then used as a heat transfer mechanism. Some data centres use cooling towers where external air travels across a wet media so that the water evaporates. Fans expel the hot, wet air and the cooled water is recirculated. Other data centres use adiabatic economisers â where water is sprayed directly into the air flow, or onto a heat exchange surface, thereby cooling the air entering the data centre. With both techniques the evaporation results in water loss. A small 1âMW data centre using one of these types of traditional cooling can use around 25.5 million litres of water per year. Data centre water efficiency deserves greater attention. Annual reports show water consumption for cooling directly paid for by the operator, so there is an economic incentive to increase efficiency. As the total energy share of cooling has fallen with improving PUEs (Power Usage Effectiveness metric), the focus has been on electricity consumption, and so water has been a low priority for the industry. However, the largest contributor to the water footprint of a data centre is electricity generation. Where data centres own and operate the entire facility, there is more flexibility for exploring alternative sources of water, and different techniques for keeping ICT equipment cool.

Topic: Trade-offs in the energy transition.
Engineering disciplines: Chemical engineering, Electrical engineering, Energy.
Ethical issues: Sustainability, Honesty, Respect for the environment, Public good.
Professional situations: Communication, Bribery, Working cultures.
Educational level: Intermediate.
Educational aim: Practise ethical reasoning. Ethical reasoning applies critical analysis to specific events in order to consider, and respond to, a problem in a fair and responsible way.
Learning and teaching notes:
This case requires an engineer with strong convictions about sustainable energy to make a decision about whether or not to take a lucrative contract from the oil industry. Situated in Algeria, the engineer must weigh perspectives on environmental ethics that may differ from those informed by a different cultural background, as well as navigate unfamiliar workplace expectations. The engineerâs own financial wellbeing is also at stake, which may complicate decision-making. As a result, this case has several layers of relations and potential value-conflicts. These include values that underlie assumptions held about the environment and its connection to human life and services.
This case study addresses two of AHEP 4âs 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 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. To prepare for activities related to environmental ethics, teachers may want to read, or assign students to pre-read the following academic articles: âEnvironmental ethics: An overviewâ or âMean or Green: Which values can promote stable pro-environmental behavior?â
Learners have the opportunity to:
analyse value assumptions related to environmental ethics;
consider whether decisions made by an engineer are ethically acceptable or unacceptable;
undertake cost-benefit and value trade-off analysis in the context of an ethical dilemma;
practise argument and reasoning related to an ethical dilemma;
use heuristics to help ethical decision-making.
Teachers have the opportunity to:
introduce concepts related to values in environmental ethics;
informally evaluate studentsâ argument and reasoning skills;
integrate technical content in the areas of chemical and / or electrical engineering related to energy trade-offs;
highlight heuristics as tools for ethical decision-making;
address cultural and professional norms in different countries.
You are an electrical engineer who had a three-year contract with a charity in Algeria to install solar systems on remote houses and farms that were not yet connected to the grid. The charityâs project came to an end and you have set up your own company to continue the work. It has been difficult raising money from investors to fund the project and the fledgling business is in debt. It is doubtful that your company will survive for much longer without a high-profit project.
During your time in Algeria, you have made many local and regional contacts in the energy industry. Through one of these contacts, you learn of an energy company operating a large oil field in the region that is looking to convert to solar energy to power its injection pumping, monitoring, and control systems. In doing so, the oil field will eliminate its dependency on coal-fired electricity, increasing production while boosting the companyâs environmental credentials. It also hopes to make use of a governmental tax credit for businesses that make such solar conversions.
Optional STOP for questions and activities:
1. Discussion: What is your initial reaction to using solar energy for oil and gas production? What might your initial reaction reveal to you about your own perspectives and values?
2. Discussion and activity: List the potential benefits and risks to implementing this technology. Are these benefits and risks the same no matter which country they are implemented in?
3. Activity: Research the trend for using solar energy in oil and gas production. Which companies are promoting it and which countries are using this technology?
4. Discussion and activity related to optional pre-readings: Consider how your perspective is related to the following environmental values, and pair/share or debate with a peer.
Anthropocentrism versus Biocentrism – are humans above or a part of the environment?
Intrinsic versus Instrumental – is nature inherently valuable or only valuable because of the use humans can make of it?
Holism versus Individualism – are certain elements of the environment more valuable than others, or does every part of the ecosystem have equal value?
Egoism versus Altruism – do we care about the environment as a result of what we gain from it, or regardless of human benefits?
Obligations to future generations: Do we have a responsibility to provide a safe and healthy environment for humans that donât yet exist, or for an ecosystem that will eventually change?
Dilemma – Part one:
The following week you receive a phone call in your home office. It is a representative of the energy company named Sami. He asks you to bid for the solar installation contract for the oilfield. At first you are reluctant, it doesnât seem right to use solar power to extract fuel that will contribute to the ongoing climate emergency. You explain your hesitation, saying âI got into the solar business because I believe we have a responsibility to future generations to develop sustainable energy.â Sami laughs and says âWhile youâre busy helping people who donât exist yet, Iâm trying to provide energy to the people who need it now. Surely we have a responsibility to them too?â
Sami then quotes a figure that the company is willing to pay you for the project work. You are taken aback at how large it is â the profit made on this contract would be enough to pay off your debts and give your business financial security moving forward. Still, you hesitate, telling Sami you need some time to think it over. He agrees and persuades you to attend dinner with him and his family later that week.
Optional STOP for questions and activities:
1. Discussion: Have you done anything wrong by accepting Samiâs dinner invitation?
2. Discussion: Environmental ethics deals with assumptions that are often unstated, such as the obligation to future generations. Like Sami, some people find that our obligation is greater to people who exist at this moment, not to those that donât yet exist. Do you agree or disagree with this position? Why? Can we maintain an obligation to future generations while simultaneously saying that this must be weighed against the obligations in the here and now?
3. Activity: Both cost-benefit and value trade-off analyses are valuable approaches to consider in this case. Â Determine the possible courses of action and undertake both types of analysis for each position by considering both short- and long-term consequences. [use the Mapping actors and processes article to help with this activity].
4. Activity: Using reasoning and evidence, create arguments for choosing one of the possible courses of action.
5. Activity: Undertake technical calculations in the areas of chemical and / or electrical engineering related to carbon offset and solar installations.
Dilemma – Part two:
When you arrive at Samiâs house for dinner you are surprised to find you arenât the only guest. Leila, a finance manager at the oil company is also present. During the meal, she suggests they are considering investing in your business. âAfter all,â she points out, âmany of our employees and their families could really use solar at their homes. We have even decided to subsidise the installation as a benefit to them.â
You are impressed by the oil companyâs commitment to their workers and this would also guarantee you an income stream for 3-5 years. Of course, to guarantee the investment in your company, you will have to agree to undertake the oil field installation. You comment to Leila and Sami that it feels strange to be having these formal discussions over a family meal. âThis is how we do business here,â says Sami. âYou become part of our family too.â
Optional STOP for questions and activities:
1. Discussion: Do you accept the contract to complete the installation? Do you accept the investment in your company? Why, or why not?
2. Discussion: Is this bribery? Why, or why not?
3. Activity: Role-play the conversation between Sami, Leila, and the engineer.
