The Climate Change Act 2008 requires a 34% cut in 1990 greenhouse gas emissions by 2020 and at least an 80% reduction in emissions by 2050. Residential and commercial buildings account for 25% and 18% of the UK's total CO2 emissions respectively and therefore have a significant role to play in a national decarbonisation strategy. As the UK has some of the oldest and least efficient buildings in Europe, there is substantial scope for improving the efficiency of energy end-use within UK buildings. However efforts to improve building energy efficiency, specifically the thermal efficiency of the building fabric, have to date focused primarily on the analysis and assessment of single properties. The slow uptake of insulation measures through the Green Deal and Energy Companies Obligation testifies to the difficulty of achieving these changes on a house-by-house basis. If the UK is to achieve its energy and climate policy targets, then a more ambitious whole-city approach to building energy improvements is needed. Technical innovations in remote sensing and infrared thermography mean that it is now possible to conduct building efficiency surveys at a mass scale. The challenge is how such data can be improved (for example moving from 2D plan imagery to 3D models of the built environment) and combined with systems analysis tools to inform effective retrofit strategies. The Urban Scale Building Energy Network will investigate this research challenge by bringing together five academic co-investigators with disciplinary expertise from across the building retrofit value chain from remote autonomous sensing to building physics, energy systems design, consumer behaviour and policy. Working with two experienced mentors from the fields of energy systems and building energy services, the co-investigators will undertake a series of activities in collaboration with project partners from industry and government to better understand the research challenge and develop roadmaps for future research. The activities include: - Two workshops and a series of bilateral meetings for the academic team to learn about each other's expertise and how it can be coordinated and brought to bear on the research challenge. The project mentors will play a crucial role here, helping the co-investigators to create personal development plans that will build both technical and non-technical skills for successful careers. - A workshop with over 20 representatives from government and industry to discuss previous experience and the perceived obstacles to more ambitious building energy retrofits. - An active online communications strategy incorporating a project website, YouTube videos, and a Twitter hashtag campaign in order to engage the general public and understand how households and commercial building occupants understand the challenge of transforming the UK's building stock. - A feasibility study to summarize the state of the art in new sensing technologies and analysis techniques for building thermal energy performance assessment and to identify major outstanding challenges for future research proposals. The proposed network will therefore facilitate collaboration between academics, industry, government and the general public to address a question of great national importance. The project outputs will help to create a wider understanding of the specific challenges facing the UK's aspirations for the transformation of its building stock as well as highlighting potentially fruitful avenues for research. The network therefore aspires to build upon this twelve-month programme of work and develop significant long-term research collaborations with benefits for academic knowledge, society and the wider economy.

Historic rock-mounted lighthouses play a vital role in the safe navigation around perilous reefs. However their longevity is threatened by the battering of waves which may be set to increase with climate change. Virtual navigational aids such as GPS are fallible, and reliance on them can be disastrous. Mariners will therefore continue to need the physical visual aids of these strategic structures. The loss of any reef lighthouse will be incalculable in terms of safety, trade and heritage. Plymouth University has trialled the use of recording instruments to capture limited information on the loading and response of Eddystone Lighthouse, with the support of the General Lighthouse Authorities (GLAs) having legal responsibility to safeguard aids to marine navigation around the British Isles. The study evaluated the extreme logistical constraints of lighthouse operations and the feasibility of using instrumentation to understand the response of the lighthouse to wave loads, with results strongly encouraging a comprehensive study of the load and response environment. Hence a full-scale project is proposed whereby field, laboratory and mathematical/computer modelling methods, novel both individually and collectively, will be used to assess six of the most vulnerable rock lighthouses in the UK and Ireland. Depending on the findings the investigation will then focus on extended full-scale evaluation of one lighthouse for the following two winters. The field instrumentation run by University of Exeter, and which will include modal testing and long term instrumentation will require novel procedures and technologies to be created to deal with the challenging environmental and logistical constraints e.g. of access, timing power. The modal test data will be used to guide the creation, by UCL, of sophisticated multi-scale numerical simulations of lighthouses that can be used with the data to diagnose observed performance in the long-term monitoring. The numerical structural model will also be linked with advanced physical modelling at Plymouth University's COAST Laboratory, and numerical (computational fluid dynamic) simulations. Finally, based on the structural and wave loading models, the long term monitoring will be used to characterize the wave loading in-situ at full scale. Outcomes of the project will be used to inform the comprehensive structural health monitoring of other lighthouses both in the British Isles and further afield through the International Association of Lighthouse Authorities. This will lead to the identification of structural distress and reduction in the risk of failure through preventative measures. Methods developed will also be of relevance to other masonry structures under wave loads so the project team includes a number of industrial partners: AECOM, Atkins, HR Wallingford and the Environment Agency who have interests in this area. As the UK has a large number of ageing coastal defences whose vulnerability to wave load was demonstrated in the winter 2013/14 storms, the applicability of the STORMLAMP findings to these structures is an important additional benefit of the project.

In many developing countries, rising energy demand, and consequently carbon emissions, is seen as an unequivocal indicator of increasing prosperity. This trajectory has important consequences not just for global carbon emissions but for the ability of countries such as India to achieve its developmental goals. This is because, in most developing countries, growth in energy demand far outstrips growth in supply due to the large capital investment required to build energy infrastructure. Thus, even people *with* access to energy networks often find that they are unable to meet their comfort needs due to supply shortages. However, the most critical problem is often not mean demand - e.g. mean per capita energy demand in India is only 13% that of the UK - but rather **peak demand** as it lays immense stress on already fragile networks. Hence, people's ability to attain comfortable internal conditions is compromised at the precise time that they need it the most - during extreme heat or cold. This project directly addresses the problem of peak demand reduction by aiming to eliminate peak demand in buildings, where it is created. In most developing countries, the vast majority of the building stock of the future is still to be built, so there is a real opportunity to decouple economic growth from building energy use whilst ensuring comfortable conditions. We aim to achieve this through laying the foundations for a **new science of zero peak energy building design** for warm climates. This will be achieved through a careful consideration of the weather signal (now and in the future) which is critical for any realistic assessment of mean dan peak energy demand. A second focus is on delivering a method of construction that is compatible not only with the Indian climate but also its building practices and social customs, thus avoiding the trap of an "imported" standard. This will be delivered through the creation of 60 pathways for a range of building types in 6 cities comprising different climates. Finally, we will also consider how loads can be moved between buildings to achieve a smooth demand profile at network level.

The increased frequency of extreme weather events associated with climate change results in the increased risk of surface water (pluvial) flooding, posing a great threat to the integrity and function of critical urban infrastructure. During the winter of 2013/14 twelve major winter storms occurred resulting in more than 5,000 homes, businesses and infrastructure being flooded in southern England. Green infrastructure, in the form of Sustainable Urban Drainage Systems (SUDS), has been proposed as a potential measure that is likely to have a significant effect on flood risk in urban environments. However, despite their multifunctional benefits, SUDS often fail the feasibility criteria of Flood Risk Management (FRM) cost-benefit assessment. The Environment Agency (EA) highlighted a number of knowledge gaps concerning the cost and benefits of large-scale SUDS retrofitting schemes, in particular the data to remove uncertainties concerning the economic appraisal of innovative solutions. The scientific community and engineering consultants have also recognised the importance of utilising vegetation to enhance urban water management by delivering a range of essential services to towns and cities and supporting urban adaptation to climate change. The Climate-KIC funded Blue Green Dream (BGD) project gathered eminent partners to develop tools for assessing the interactions between urban water (blue) systems and vegetated (green) areas and hence maximise the multifunctional benefits of so-called Blue Green Solutions (including SUDS). Building on that research, this project will assign green infrastructure interventions as assets by progressing knowledge and understanding of the ability of Blue Green Solutions to provide cost-beneficial Flood Risk Management services. This will be achieved by brining together the expertise from three BGD project partners - Imperial College London, Deltares and AECOM, supported by the EA Water London Team. The Decoy Brook sub-catchment in London Borough of Barnet will be used as a case study for: a) mapping of Blue Green Solutions for infrastructure protection using the Adaptation Support Tool; b) improving the cost-benefit assessment of SUDS by quantifying multifunctional benefits of innovative Blue Green Solutions; and c) producing an advanced tool for full cost-benefit analysis of the proposed SUDS retrofitting scheme in compliance with the Flood Risk Management assessment. This will enable the EA to transparently and objectively assess Blue Green Solutions against the broad range of benefits. In addition, it will provide AECOM an example of a robust business case for utilising SUDS/Blue Green Solutions to protect infrastructure that addresses the reduction in the levels of uncertainty associated with the results from such analyses. Outputs from this project will be used to provide evidence to the Greater London Authority on the development of a pan London approach to delivering sustainable drainage systems. In addition, more accurate and robust valuing of SUDS and demonstrating the full return on each pound invested will enable EA's SUDS retrofit projects to compete on an equal footing for Flood and Coastal Erosion Risk Management Grant in Aid funding.

One class of electrochemical reaction are reactions in the plasma state. The PI and his team have been pioneering plasma microreactors that feed directly into microbubbles for the last decade. With the output of the plasma reactor entering the microbubble directly, the maximum activation is retained in the bubble, which then mediates the formation of active species on the microbubble interface. Recently, this approach has been used to catalyse the esterification reaction of free fatty acids to form esters (particularly biodiesel). More than the effectiveness of the plasma activated microbubble reaction, microbubble processing is not limited by surface area of "electrode" in quite the same way. The grand aim of this proposal is to create heterogeneous catalysis capability by tuning the plasma activated species on the gas-liquid interface of microbubbles. Conventional electrochemistry has severe issues around upscaling. Plasma microreactors, particularly those that feed into liquid media as injected microbubbles, are a class of electrochemical reactors that can potentially upscale readily. Microbubbles can have hectares of gas-liquid interface per cubic metre of liquid reactant volume, so if the (plasma)electrochemical reaction can be catalysed on the gas-liquid interface, high throughput reaction rates can be achieved in large volume, continuous flow reactors. Already achieved in pilot plant studies of anaerobic digestion is a bubble surface area flux of 0.15 hectares/sec! If even a fraction of this surface area flux is effective at mediating plasma chemical transformations, the rate of transformation processes should far exceed conventional heterogeneous reactions. This project aims to optimise how the formation of plasma-activated species is coupled to the transient operation of the plasma electronics that create the excited species that eventually react at microbubble gas-liquid interfaces. Preliminary studies show that the composition of an excited air plasma, for instance, can dramatically change with the contacting time in the reactor and the electric field applied. They also suggest that how that electric field is applied in space and time dramatically affects the chemical composition of the plasma, and consequently what chemical reactions dominate the microbubble mediated gas-liquid chemistry. The purpose of this proposal is to characterise this coupling between the time-varying plasma electronics output, as implemented with tuneable electrical engineering design, and the induced chemistry of the plasma and microbubble mediated reaction. The characterisation will be captured in computer models that permit inversion; from the desired chemical outputs, the optimum plasma electronics design, control and operating mode ("the waveform") will be predicted. In the UK plasma chemistry research is vibrant but the work is mainly centred on nuclear science, capactively coupled plasmas with applications to surface treatment (i.e. EP/K018388/1) and medical applications. Globally, several research groups are investigating tailored waveform plasmas more generally but not with specific application to chemical generation on an industrial scale. The proposed closed-loop control of tailored waveform plasma microbubble reactors offers new possibilities to increase efficiency, throughput and scale-up. This, therefore, complements the contributions from these research groups (both national and international) and so will stimulate new research and commercial opportunities. By bringing together experts from the interface of chemical engineering, electrical engineering and mathematics who, together with some eight project partners providing £160k of support, can drive a blue-skies approach to targeted waveform control of plasma reactions (using novel chemical modelling and waveform generator design) while blazing a trail for industrial adaptation to a game-changing approach to chemical production.
