Dr Sara Walker is currently Director of Expertise for Infrastructure Research in the School of Engineering. Her research is on energy efficiency and renewable energy at the building scale.
Dr Walker spent eight years at De Montfort University, where her research and teaching focussed on renewable energy and energy efficiency technologies, and where she also completed a PhD part time. This PhD investigated the impact of electricity sector deregulation on renewable energy market share. During that period with De Montfort University, Dr Walker worked on a number of research projects around renewable energy and energy efficiency, primarily funded by the European Commission.
Dr Walker then moved out of academia and into industry, with a five year period in energy related consultancies. This consultancy work for Econnect and IT Power included contribution to the influential report “Potential for micro-generation: study and analysis” published by Energy Saving Trust for the DTI. Dr Walker also worked on high profile projects for commercial clients, such as London Array.
In 2007, Dr Walker joined Northumbria University and continued her research on renewable energy and energy efficiency. She also developed new programmes, including the MEng Building Services Engineering, and successfully ran programmes, managed staff and developed research and business outreach. Her first role was as Subject Director for the Building Services team. Following a restructure she took on the role of Director of Research and Engagement for the Department of Architecture, Construction and Engineering. Later she was promoted to a Faculty role, as Director of Business and Engagement for the Faculty of Engineering and Computing.
In September 2015 Dr Walker joined Newcastle University in the School of Mechanical and Systems Engineering. She was Degree Programme Director for the MSc Renewable Energy Flexible Training Programme (REFLEX) and MSc Renewable Energy and Enterprise Management (REEM) until 2017. In 2017 she became Director of Expertise for Infrastructure research and member of the School of Engineering Executive Board. Her research continues to focus on renewable energy and energy efficiency in buildings, energy policy, energy resilience, and whole energy systems.

MSc Environmental Science, 1993-1994, Nottingham University, thesis: "Impact of thermal comfort on Sudden Infant Death Syndrome".
PhD, 1997-2003, De Montfort University, thesis: "The impact of domestic electricity supply competition on the application of renewable energy technologies in the UK".
The energy sector in 2050 is likely to be very different to it’s current state, with changes expected to our supply and demand technologies. I am interested in the active role of the urban environment and buildings in the energy sector, particularly low-energy and low-carbon buildings, building-scale renewables, small scale energy storage, and electric vehicle charging/discharging load profiles. As we decarbonise heating, cooling, electricity and transport in the UK, my research aims to better understand the role of buildings as virtual power plants.
I am also interested in concepts of resilience as they are used in other disciplines, and whether these concepts are transferable to the energy sector. Existing concepts of resilience and supply security may not be appropriate to the energy sector in 2050.
Co-Investigator and Academic Deputy Director for the Active Building Centre.
The £36m Active Building Centre project will investigate the potential for large scale role out of domestic active buildings for the new build sector. Researchers at Newcastle University shall investigate the impact of active buildings on the energy networks, smart control of building elements, and the role of electric vehicles. Overall, energy demand, generation, storage and transport combine to enable the active building to be controlled to offer services to local networks, as well as ensuring energy services to the building occupant.

Co-Investigator and Associate Director for the National Centre for Energy Systems Integration.
The £20m EPSRC National Centre for Energy Systems Integration (CESI) paves the way to a flexible smart infrastructure, empowering customers and giving them greater control of their energy use. It allows industry to meet the tough new low carbon targets. Providing us with robust messages about the real world, the aim is to understand how we can optimise the energy network, drive down customer bills and inform future government policy.

Co-Investigator and Deputy Director for the EPSRC Supergen Energy Networks Hub.
The £17m EPSRC Supergen Energy Networks Hub brings together the academic community to work on the issue of developing networks fit for the future. The research addresses the challenges of technology, policy, data, markets and risk for energy networks.
Grant ref: EP/S00078X/1
Principal Investigator for Building as a Power Plant
This project will investigate the feasibility of the Urban Sciences Building (Newcastle University) to offer services to the local network. The building is an interesting case study since it includes electricity generation, storage and demand, and thermal generation, storage and demand.
