The 2024 Christmas Switch Off at Newcastle University

What is the Christmas Switch Off?

The Christmas Switch Off is a University-wide campaign where we encourage staff and students to turn off any electrical items that can be switched off instead of leaving them on standby over the Christmas break.

Why is the Christmas Switch Off important?  

By turning off everything that can be turned off, we will reduce our energy consumption across the campus. The Christmas Switch Off campaign has been run for a number of years to minimise energy wastage and contribute to our carbon reduction targets.

We also hope that promoting of the Christmas Switch Off will promote positive behaviour change more widely and remind colleagues and students to minimise their energy wastage by remembering to switch off what they can every day.

Who participates in the Switch Off?

We would like everyone at the university to participate if they are able to, that includes staff and students across labs, offices, and accommodation. The advice on what to turn off will vary for each location – guidance on what should be switched off is in this blog post. 

When switching off your work area, it can be helpful to organise a switch off team that can check each area after most people have left for the term to ensure everything that can be switched off, has been.

Here are some examples of items that could be switched in various area across campus:

  • Staff working in offices: Lighting, computers, monitors, printers and photocopiers, kettles and fridges (after they have been emptied and cleaned). Also, it is important to make sure that all windows have been properly closed. 
  • Labs and medical buildings: All the above can be applied in addition to drying cupboards, fume cupboards and fridges/freezers that will not be in use over the break (please do not turn off equipment that is in use).

Many students leave their accommodation over the Christmas break, meaning their accommodation will be empty over the holidays. If you are going away over the winter break, there are a few things that you could do before you leave:

  • Clean out and defrost your fridges and freezers the day before you leave by turning them off at the wall and popping a towel underneath to soak up the melted ice.
  • Turn off your kettles and toasters at the wall.
  • If there is a wall switch for your oven this is also a good thing to turn off easily, as well as lights and plug sockets.

COP 29: Apply to be a Virtual Delegate! 

The 2024 United Nations Climate Change Conference, also known as the 29th Conference of the Parties, or COP 29, is set to take place in Baku, Azerbaijan from the 11th – 22nd of November. Conference discussions are expected to centre on themes of climate finance, carbon markets and new Nationally Determined Contributions (NDC’s) – the national targets to support climate change commitments that countries must submit in 2025.   

This year, we have the opportunity for 10 University representatives to attend the conference virtually. Keep on reading to find out more about being a virtual delegate, and how you can apply!

What is an observer?  

Newcastle University gained “observer organisation” status with the UNFCCC in 2021 and a delegation of academics, professional services colleagues and student representatives were able to attend COP 26 in Glasgow as a result. Observer organisations can select representatives to attend the annual COP’s both in-person and virtually. This year, for COP 29, all observer organisations have been allocated 10 virtual delegate places – though in-person quotas have been limited. 

Observers are chosen from a variety of groups, all expressing unique perspectives on climate change. They fall into one of three groups: United Nations organisations, intergovernmental organisations (IGOs) and non-governmental organisations (NGOs). 

NGOs can include: 

  • Youth groups 
  • Trade unions 
  • Farmers 
  • Indigenous communities 
  • Environmental charities 
  • Research organisations including universities. 
  • Gender-equality initiatives 

Virtual delegates can access many meetings and events being held at the COP 29 conference, though often this is limited to being able to observe proceedings via a one-way live stream.  As well as the main negotiations between Parties to the Convention, COP conferences host hundreds of related side-events, exhibits and meetings every year. Observer organisations can apply to host side-events at the conference and many of this year’s events should be available to view by virtual delegates.  Some events may even interact with the online community, allowing you to network with peers and have your say! 

More information about observer organisations is available here on the UNFCCC website, and a list of this year’s formal side-events is available here. The list will most likely be updated as the conference nears, so keep checking for new events!

How can I apply? 

This year, we are encouraging both students and colleagues to apply to be a virtual delegate. We will select delegates on a first come, first serve basis. We will also try to ensure a balance of undergraduate students, postgraduate taught students, postgraduate research students, academic colleagues, and colleagues from professional services.  

To apply, simply fill out the form below telling us your availability and why you would like to attend.  Please note, it is not expected that virtual delegates will commit the whole of their time to the COP – we would encourage our virtual delegates to attend as many events as their commitments will allow.  

By filling out the form, you will also consent to helping the Sustainability Team with a follow-up blog or knowledge-sharing activity, describing your experience at COP 29. You will also agree to abide by the UNFCCC Code of Conduct found here

Good luck! 

Sustainable innovations: designing the homes of the future in the _OME

Completed in June 2021, the _OME is the flagship research and showcasing facility of the Hub for Biotechnology in the Built Environment (HBBE), an innovative research partnership set up between Newcastle and Northumbria Universities. With funding from Research England, the HBBE combines expertise in biosciences, design, architecture, and engineering to advance cutting edge research on biotechnology. As part of this, the team, now made up of nearly seventy researchers and support staff (HBBE, 2022), are constantly testing ways to improve the health and sustainability of our homes by researching everything from controlling the spread of pathogens to innovating on sustainable technologies. This diverse and hugely beneficial work is centred on the state of the art _OME facility, so how exactly are these exciting projects designing the living spaces of the future?

Located on Devonshire walk, next to the Great North Museum: Hancock and the Devonshire and Drummond buildings, the _OME houses an in-house experimental apartment, accompanying laboratory, and display space for innovative materials and technologies. The HBBE’s research is organised into four key themes and utilises concepts including the genome, biomes, and home, hence the name: _OME. The four research themes being undertaken in the facility touch on a variety of repurposed, improved, and novel technologies and practices to lower carbon footprints and keep us healthy by design. So what do they all involve?

Theme 1: Building Metabolism

The first theme focusses on building-wide methods to achieve a higher degree of sustainable self-sufficiency by creating an artificial ‘metabolism’ in the structure and systems of the house itself. Practical examples of how this metabolism works include generating renewable electricity on site via solar panels on the building’s roof and utilising greywater to lower water use by, for example, reusing water from sinks or the shower to flush the toilet. Additionally, other technologies being woven into this metabolism include rainwater harvesting from the roof gutters and developing waste handling systems within homes that can deal with waste on site and even generate heat and other useful resources from it! When combined, these technologies could work to maintain a living space with a fraction of the energy and water requirements of a standard home, helping to save on both carbon and bills!

Theme 2: Living Construction

The construction sector is a major emitter of carbon globally and commonly used materials including steel and concrete require an awful lot of energy to produce (Wang and Ramakrishnan, 2021), leading to homes with high embodied emissions. Thankfully, lower carbon materials, including cross-laminated timber, are becoming more commonly used (Ahmed et al., 2024), but researchers at the HBBE are looking to advance construction even further by developing intelligent materials. The focus of this research sits squarely on bio-materials, including biominerals, biopolymers, and hygromorphs, which promise not only to lower embodied emission further, but also to offer other advantages. One exciting potential feature of these biomaterials would be to respond to certain stimuli and regrow their structures when damaged – creating self-repairing buildings! These innovations would further add to the construction sector’s arsenal of sustainable building techniques, giving architects more tools to create buildings that are good for both people and planet.

Theme 3: Microbial Environments

The third theme touches on the _OME’s creation mid-way through the Covid 19 pandemic. Here, research teams are designing homes to better support healthy microbiomes and passively reduce the spread of illnesses, including pandemics. Proposed technologies for achieving this include smart ventilation, antimicrobial materials, and advanced microbiome monitoring systems to better understand what’s going on in the home. Not only will these innovations improve people’s health, but they could also reduce the environmental costs of dealing with illnesses and epidemics (see our sustainable medicine blog here) by creating environments that are far better at handling these issues by design.

Theme 4: Responsible Interactions

As seen previously, the HBBE is working on a variety of innovative technologies, but implementation of these isn’t always smooth sailing. To help ease biotechnologies’ transition from research to widespread use, therefore, researchers are investigating a variety of potential potholes, from accessibility concerns to unintended environmental effects. Additionally, ensuring these new technologies can seamlessly integrate with existing practices and standards, and making sure that people are culturally on board to accept innovations such as biomaterials, remains an important challenge. The _OME is major part of the solution here, as novel technologies can be tested out in the living laboratory and new materials can be shown off to unsure potential adopters, helping to tackle challenges before they become significant issues.

Thank you to the amazing HBBE team for their innovative work and their dedication to improving the sustainability of our built environment. Upon its completion in 2021, the _OME joined a series of Living Labs associated with Newcastle University across campus and elsewhere. These facilities look to continually generate high quality research and data as part of their site’s design (often while being used for a variety of other useful purposes) and you can learn more about them here. Additionally, further information on the HBBE’s activities, including its publications and additional research groups, can be found here.

Solar power on campus: Harnessing renewable energy to power our university.

Why is renewable energy important?

As attested in UN Sustainable Development Goal 7, ensuring that our power is being generated renewably is a vital part of meeting climate goals, whether national, international, or across individual organisations (White, 2024). Here at Newcastle University, lighting accounts for around 20% of our energy use alone, but electricity is also used to power many building’s heating, cooling, and ventilation systems, our fleet of electric vehicles, our PCs, server banks, lab equipment, and more. With so much of the University drawing on electrical power, therefore, generating renewable energy on campus can have a huge impact on reducing the emissions of our facilities and operations. One technology that has proven invaluable in our efforts to increase local renewable energy production is solar power.

What’s happening at our university?

Solar Photovoltaics (PV) have been producing power since the 19th Century but have only really become commonplace in the last few decades as lowering costs and improving efficiencies have made the technology increasingly commercially viable (Mulvaney, 2019). One of the chief benefits of solar PV is its versatility. Solar arrays can produce power wherever there is good access to daylight (a full explanation of how solar PV works can be found in this blog) and can be deployed on building rooftops to easily integrate power production into dense urban environments (Hayat et al., 2019). This adaptability has allowed the University to install solar arrays on a wide variety of buildings across our city centre campus, and these systems generate power right where it’s needed most.

As the above maps show, solar arrays have been installed across campus including on buildings such as the Henry Daysh, Great North Museum Hancock, the Catalyst, and every block of the Park View Student Village. Our teams are also continually working to expand the amount of solar power we generate at the University and we’re currently constructing a new system on top of the Philip Robinson Library. Additionally, as we add new arrays, we’re constantly looking to expand their capacity and our recently finished Sports Centre system, now the largest at the University, generates as much power in under 2 days as an average UK household consumes in a year! Elsewhere, arrays have been designed to meet the entire daytime power demands of buildings – such as in our Frederick Douglass Centre, who’s generation data can be seen below.

A combined approach

The effects of the University’s solar power arrays are already being felt across our organisation. In addition to the savings on energy bills these systems are creating, the University is also saving tens of thousands of kilograms of CO2e across our facilities. Following these successes, we’ll continue to install new solar PV systems across our campus and beyond while working to complement these projects with other renewable and low carbon infrastructure initiatives. Examples of these complimentary improvements include:

  • Our low carbon factor combined heating and power engine in the Merz Court Energy Centre which utilises biofuel to provide electricity and hot water with a high degree of efficiency and a far lower comparative carbon footprint.
  • Projects to link the district heating networks we have across our city centre campus, improving efficiencies and reliability as systems help to pick up each other’s slack and can optimise over a wider area.
  • Our long-term campus-wide LED works to replace all indoor room lighting across our organisation with energy efficient LEDs. We’re now well over halfway through this decade long project!
  • The energy supply deal we’ve struck with The Energy Consortium to supply our buildings and facilities with zero carbon power from the grid.

Catching the Tailwinds: Wind power and the green energy transition at Newcastle University

What is Wind Power?

Wind power is a renewable source of energy that harnesses the kinetic force of natural air flows. To do this, turbine blades are angled so that the passing winds push against them and transfer their energy into rotational movement. This movement then drives a generator that transforms the kinetic energy into electrical power. Similar processes, minus the last step, have been utilised for millennia for purposes including milling grain, pumping water, and, in their simplest form, navigating oceans. Since the 1970s, however, the technology’s potential to generate electricity at scale has led to a gradual modern resurgence of wind power as a useful tool in the global transition towards cleaner and greener energy (Chiras, 2010). To understand how Newcastle University is responding and contributing to this transition, I’ve drawn on the expertise of Professor of Offshore Engineering, Zhiqiang Hu, to explore some of the exciting projects in progress across our organisation.

The University’s wind research and collaborations

Our University has a range of talented researchers working across a variety of wind power technologies and among of the most promising of these is offshore wind generation. Placing wind turbines offshore (sometimes a long way out at sea!) allows them to be far larger than their land-based siblings which boosts generation capacity while avoiding taking up precious space on land. As a result, the offshore wind industry is developing quickly as an important way to meet the global demand for decarbonisation. This is creating a wealth of challenges and opportunities for those working in the sector and Newcastle University has a strong position within this dynamic landscape thanks to two key factors.

Firstly, the University has attracted attention from a variety of leading energy and engineering companies thanks to both our wealth of specialist knowledge and the forward-looking approach to sustainability that we take throughout our institution. Our researchers are working on a variety of cutting-edge themes, specialising particularly in the strength and integrity of wind turbines, their operation and maintenance, and developing ways to store their excess generation as hydrogen! Meanwhile, to help power this research, the University has entered a long-term deal to acquire wind power from Statkraft – a major European wind power supplier.

Secondly, the North-East is also a busy place for offshore wind power industrially, due both to the region’s existing maritime infrastructure and the vast wind farm being developed at nearby Dogger Bank in the North Sea. This wind farm, projected to be the largest in the world, has created a strong local offshore wind power supply chain, further attracting investment and collaboration with leading companies eager to work with local centres of expertise such as our University. These factors have led to a variety of exciting projects collaborating with industry including:

  • Professor Hu’s work to collaborate with colleagues and companies, including ORE Catapult, Hywind Scotland, and Equinor, to develop technologies (including using AI (Chen et al., 2021)) that will help maintain floating wind turbines at sea.
  • The University’s Hydrodynamics Laboratories in the Armstrong Building have been working with Balmoral to develop their HexDefence technology to avoid scouring issues at the base of offshore turbines (read more about scouring here (Zhang et al., 2023)).
  • Newcastle University’s Marine Zero PhD Centre has been supporting TechnipFMC on a project to develop dynamic cable monitoring technology to ensure that power gets back to land safely from the turbines out at sea.

Impact beyond the University

The varied partnerships and research projects underway at our University are creating opportunities and positive change within our organisation, but the work that’s being done here is having impacts far beyond the streets of our campus. Here, the University’s work contributes to positively impacting the emissions profile of the entire North East, proving the possibilities of decarbonising UK higher education, and providing vital knowledge that will contribute to the global green energy transition!

Enormous thanks to Professor Hu for the expert insight he provided for this article, you can see more of his work here.

What is solar energy?

There are many ways that energy is created across the world, and these are grouped into renewable and non-renewable energy sources. Non-renewable energy refers to natural sources that take thousands of years to form and produce harmful greenhouse gases when they are burned for energy. The most used non-renewable energy sources are coal, oil, and gas, also known as fossil fuels.

When fossil fuels are burned, they produce greenhouse gas emissions which trap in the world’s heat and raise the global temperature. The world is currently experiencing a climate crisis due to increased global temperature. There are numerous negative impacts that are being felt internationally due to the climate crisis, such as increased natural disasters and accelerated loss of species.

Renewable energy refers to various natural sources that replenish themselves rapidly, unlike non-renewable energy sources. Sources of renewable energy include solar, wind, wave, geothermal, tidal, and hydro-electric.

Within this post we will be outlining what solar energy is, how solar energy works, and we will explore solar energy’s presence on Newcastle University’s estate.

What is solar energy?

Solar energy is initially generated by the sun in a constant and renewable process of nuclear fusion. This energy is what lights and warms our planet during the day.

How is solar energy turned into usable power?

Solar energy can be harnessed using multiple methods, the most common method uses photovoltaic systems. Photovoltaics are used in solar cells and panels which form what is known as arrays when they are placed together in groups. Photovoltaics use semiconductors such as silicone to absorb sunlight and generate electricity in the form of a direct current. When the energy has been generated, it is then converted into an alternating current so that it can power objects within a building, which is completed by an inverter.

Why is Newcastle University investing in solar energy?

Newcastle University has invested in solar energy for a plethora of reasons. The installation of solar panels on our current infrastructure such as roof tops is relatively simple, whereas the installation of small-scale wind energy infrastructure is difficult on our campus due to the vast amount of space required. Solar energy is also scalable, the number of panels required depends on the amount of energy required by the University, as this ensures that we can generate this energy on campus instead of buying it. Solar energy is also incredibly efficient and has a medium cost level to high efficiency and production ratio, meaning it is a desirable form of energy to produce for Newcastle University’s needs.

Close up of a solar panel

Current use of solar energy on Newcastle University’s estate

Newcastle University currently has 13 solar arrays in a variety of sizes. The energy created by these solar arrays contributes towards the energy usage of the University. Some of the arrays on campus are made up of a few panels on smaller buildings, but we also have a number of larger arrays on buildings like King’s Gate, Henry Daysh, and the Frederick Douglass Centre.

We use a software called Solar Edge to monitor the amount of electricity being created across the arrays. The system also recognises if one of the panels becomes damaged and informs us.
