The UK is on the brink of a new, third age of energy efficiency. UK greenhouse gas emissions must fall a further 65% by 2050, but the energy system will decarbonise even faster. Large wind, marine and solar generators, supported by energy storage, will dominate the central supply system and intelligent, community and building-integrated systems will be embedded in our towns and cities. This interaction of people, buildings and energy systems will transform the relationship between supply and demand. Our domestic and non-domestic buildings can no longer be passive consumers of heat and power, instead, our homes and businesses must participate actively in a flexible, integrated, low-carbon supply and demand system, buying, selling and storing heat and power to achieve 'Energy resilience through security, integration, demand management and decarbonisation'. This must be achieved whilst simultaneously meeting our human need for high quality spaces in which to live and work, thereby increasing the productivity of the UK economy, reducing fuel poverty, improving health and wellbeing, and supporting an ageing population. The new EPSRC CDT in Energy Resilience and the Built Environment (ERBE) will train at least 50 PhD graduates to understand the systemic, radical, multi and interdisciplinary challenges we face, and have the leadership credentials to effect change. Students will be immersed in world-leading research environments at UCL, Loughborough University collaborating with the Centre for Marine and Renewable Energy in Ireland. ERBE students will attain a depth of understanding only possible as cohorts work and learn together. An integrated, 4-year programme will be co-created with our stakeholder partners and students. It will provide the knowledge, research and transferable skills to enable outstanding graduates from physics to social sciences to pursue research in one of three themes: * Flexibility and resilience: the interaction between buildings and the whole supply system, through new generation and storage technology, enabled by smart control systems and new business models. * Technology and system performance: demand reduction and decarbonisation of the built environment through design, construction methods, technological innovation, monitoring and regulation. * Comfort, health and well-being: buildings and energy systems that create productive work environments and affordable, clean, safe homes. The Centre will be led by Directors who have worked together for over 30 years, supported by deputies, academic managers, administrators and a course development team who have successfully delivered the CDT in Energy Demand. Over 50 world-leading academics are available as student supervisors. The core team will be guided by an Advisory Board representing the UK government, energy suppliers, research organisations, consultancies, construction companies and charities; more than 30 prominent individuals have expressed an interest in joining the board. Board members and stakeholders will provide secondments, business skills training and careers advice. The Centre will provide training and research benefits to the wider energy and buildings community. A new online Buildings, Energy, Resilience and Demand Hub will be created to share training materials, videos, seminars and to promote collaboration, a residential, weeklong programme, Energy Resilience and the Built Environment, will be open to PhD students from across the world as will an annual, student-led conference. An annual Anglo-Irish summer school and a colloquium will showcase the Centre's work and bring students face-to-face with potential future employers. By providing training in a rigorous, world-leading, stakeholder-shaped, outward-facing and multi-centred research environment, the new ERBE CDT will help the UK achieve the goals in the government's Industrial Strategy and Clean Growth Strategy.
