The surface urban transport infrastructures - our roads, cycle ways, pedestrian areas, tramways and railways - are supported by the ground, and hence the properties of the ground must control to a significant degree their structural performance. The utility services infrastructure - the pipes and cables that deliver utility services to our homes and which supports urban living - is usually buried beneath our urban streets, that is it lies below the surface transport infrastructure (usually roads and paved pedestrian areas). It follows that streetworks to install, replace, repair or maintain these utility service pipes or cables using traditional trench excavations will disrupt traffic and people movement, and will often significantly damage the surface transport infrastructure and the ground on which it bears. It is clear, therefore, that the ground and physical (i.e. utility service and surface transport) infrastructures exist according to a symbiotic relationship: intervene physically in one, and the others are almost inevitably affected in some way, either immediately or in the future. Moreover the physical condition of the pipes and cables, of the ground and of the overlying road structure, is consequently of crucial importance in determining the nature and severity of the impacts that streetworks cause. Assessing the Underworld (ATU) aims to use geophysical sensors deployed both on the surface and inside water pipes to determine remotely (that is, without excavation) the condition of these urban assets. ATU builds on the highly successful Mapping the Underworld (MTU) project funded by EPSRC's first IDEAS Factory (or sandpit) and supported by many industry partners. The MTU sandpit brought together a team that has grown to be acknowledged as international leaders in this field. ATU introduces leaders in climate change, infrastructure policy, engineering sustainability and pipeline systems to the MTU team to take the research into a new sphere of influence as part of a 25-year vision to make streetworks more sustainable. ATU proposes to develop the geophysical sensors created in MTU to look for different targets: indications that the buried pipes and cables are showing signs of degradation or failure, indications that the road structure is showing signs of degradation (e.g. cracking, delamination or wetting) and indications that the ground has properties different to unaltered ground (e.g. wetted or eroded by leaking pipes, loosened by local trench excavations, wetted by water ingress through cracked road structures). For example, a deteriorated (fractured, laterally displaced, corroded or holed) pipe will give a different response to the geophysical sensors than a pristine pipe, while wetting of the adjacent soil or voids created by local erosion due to leakage from a water-bearing pipe will result in a different ground response to unaltered natural soil or fill. Similarly a deteriorated road (with vertical cracks, or with a wetted foundation) will give a different response to intact, coherent bound layers sitting on a properly drained foundation. Taking the information provided by the geophysical sensors and combining it with records for the pipes, cables and roads, and introducing deterioration models for these physical infrastructures knowing their age and recorded condition (where this information is available), will allow a means of predicting how they will react if a trench is dug in a particular road. In some cases alternative construction techniques could avert serious damage (e.g. water pipe bursts, road structural failure requiring complete reconstruction) or injury (gas pipe busts). Making this information available will be achieved by creating a Decision Support System for streetworks engineers. Finally, the full impacts to the economy, society and environment of streetworks will be modelled in a sustainability assessment framework so that the wider impacts of the works are made clear.

Addressing climate change through reducing carbon emissions is a crucial international goal. End use energy demand (EUED) reduction is essential for the UK to meet its legally binding 80% carbon reduction target and has significant economic and social benefits: it lowers the operating costs of businesses, increasing their competitiveness, and reduces the fuel bills for home owners, guarding against fuel poverty and improving quality of life. Government, industry and academia recognise the importance of EUED reduction and are responding by developing new policies, products and services. However, there is a shortage of highly trained individuals who will spearhead these initiatives. Recognising this, the Engineering and Physical Science Research Council (EPSRC) has identified EUED in buildings, transport and industry as a priority funding area for the development of a Centre for Doctoral Training (CDT). For the last 4 years, the UCL Energy Institute and the School of Civil and Building Engineering at Loughborough, have run a successful CDT: the London-Loughborough Centre for Doctoral Research in Energy Demand (LoLo). The Centre is seeking funding for a further 8 years to train 60 students. The scope will be expanded beyond buildings to include energy demand in transport and industry directly related to the built environment. The new Centre will build on the existing four year programme: a one year Masters of Research in Energy Demand followed by a three year PhD. Training will be enhanced by an annual colloquium; international summer school; team building away days; seminar series'; creativity, communication and business training; and numerous other activities. Students will undertake placements with partners and in relevant overseas organisations. They will have a firm grounding in core skills and knowledge, but appreciate the multi-disciplinary perspective needed to understand the technical, economic and social factors that shape energy demand. The Centre's research will address new challenges within five themes, grouped around major research programmes: technology and systems, energy epidemiology, urban scale energy demand, building performance and process, and unintended consequences. This linkage ensures students' work gains momentum, is at the forefront of knowledge, has excellent resources, and is supported by a wide group of world class academics. The Centre will again be led by Profs Lowe and Lomas; together they have over 60 years of experience in energy and buildings. They will be supported by Academic Managers and Administrators and over 40 academic supervisors whose expertise spans the full range of disciplines necessary for EUED research: from science and engineering to ergonomics and design, psychology and sociology through to economics and politics. An Advisory Board will help steer the Centre, whilst the wider group of 26 partners, representing policy, industry, academia and NGO interests, will aid students' training by: developing projects, offering mentoring, hosting students in their organisation, giving workshops and seminars, and direct funding. The proposed new Centre represents excellent value for money. The total cost to the EPSRC to train 60 students is less than the current Centre cost to train 40 students. However, the funding per student will rise by 20%, a result of the financial commitment of our partners and host institutions. The Centre aims to have an enduring impact through our graduates and their research. Short term impact will be achieved through students' engagement with industry, policy makers, NGOs and academia through the annual Colloquium, the international summer school, publications, the web-site and other social media, working with partners and through public engagement. In the long term our graduates will help transform the EUED sector through projects they lead, the students and colleagues they will train and the organisations they influence.

Infrastructure is a large part of the UK's assets. Efficient management and maintenance of infrastructure are vital to the economy and society. The application of emerging technologies to advanced health monitoring of existing critical infrastructure assets will quantify and define the extent of ageing and the consequent remaining design life of infrastructure, thereby reducing the risk of failure. Emerging technologies will also transform the industry through a whole-life approach to achieving sustainability in construction and infrastructure in an integrated way - design and commissioning, the construction process, exploitation and use, and eventual de-commissioning. Crucial elements of these emerging technologies will be the application of the latest sensor technologies, data management tools and manufacturing processes to the construction industry, both during infrastructure construction and throughout its design life. There will be a very substantial market for exploitation of these technologies by the construction industry, particularly contractors, specialist instrumentation companies and owners of infrastructure.In this proposal, we seek to create the Innovation and Knowledge Centre for Smart Infrastructure and Construction that will bring together four leading research groups in the Cambridge Engineering Department and the Computer Laboratory (sensors, computing, manufacturing engineering and civil engineering), along with staff in other faculties - the Judge Business School and the Department of Architecture. The Centre will develop and commercialise emerging technologies which will provide radical changes in the construction and management of infrastructure, leading to considerably enhanced efficiencies, economies and adaptability. We propose to create 'Smart Infrastructure' with the following attributes: (a) minimal disturbance and maximum efficiency during construction, (b) minimal maintenance for new infrastructure and optimum management of existing infrastructure, (c) minimal failures even during extreme events (fire, natural hazards, climate change), and (d) minimal waste materials at the end of the life cycle. The IKC will focus on the innovative use of emerging technologies in sensor and data management (e.g. fibre optics, MEMS, computer vision, power harvesting, Radio Frequency Identification (RFID), and Wireless Sensor Networks). These will be coupled with emerging best practice in the form of the latest manufacturing and supply chain management approaches applied to construction and infrastructure (e.g. smart building components for life-cycle adaptive design, innovative manufacturing processes, integrated supply chain management, and smart management processes from building to city scales). It will aim to develop completely new markets and achieve breakthroughs in performance.The business opportunities in construction and infrastructure are very considerable, not only for construction companies but also for other industries such as IT, electronics and materials. The IKC is designed to respond directly and systematically to the input received from industry partners on what is required to address this issue. Through the close involvement of industry in technical development as well as in demonstrations in real construction projects, the commercialisation activities of emerging technologies will be progressed during the project to a point where they can be licensed to industry. The outputs of the IKC will provide the construction industry, infrastructure owners and operators with the means to ensure that very challenging new performance targets can be met. Furthermore the potential breakthroughs will make the industry more efficient and hence more profitable. They will also give UK companies a competitive advantage in the increasingly global construction market.

LoHCool focuses on topic T1 'Delivering economic and energy-efficient heating and cooling to city areas of different population densities and climates'. It confronts directly the conundrum of offering greater winter and summer comfort in a Continental climate zone whilst mitigating what would be a carbon penalty of prodigious proportions. It concentrates on recovering value from the existing building stock, some 3.4 Billion m2 in which dwell and work some 550 Million citizens. It is highly cross-disciplinary involving engineers, building scientists, atmospheric scientists, architects and behavioural researchers in China and UK measuring real performance in new and particularly in existing buildings in Chinese cities to investigate the use of passive and active systems within integrated design and re-engineering. It focuses on the very challenging dynamic within China's Hot Summer/Cold Winter HSCW climate zone. It aims to enable the much desired improvements in living conditions and comfort levels within buildings through developing a keen understanding of the current heating and cooling technologies and practices in buildings by monitoring, surveying and measuring people's comfort and capturing this understanding through developing systems modelling including energy simulations. It will borrow on UK research for comparative purposes, for example work examining the current and future environmental conditions within the whole National Health Service (NHS) Hospital Estate in England and the practical economic opportunities, very considerable, for significant improvement whilst saving carbon at the rate required by ambitious NHS targets. It will propose detailed practical and economic low and very low carbon options for re-engineering the dominant building types which we will identify in a series of cities, as developed with local stakeholders, contractors and building professionals, exploring economic and energy-efficient low carbon district heating and cooling systems. Finally, it will test them in the current climate, 'current' extreme events, future climates and will estimate the carbon implications and cost of widespread implementation. Findings for the existing stock will be equally applicable to new-build, in many ways a simpler prospect.
