Both the UK and China face great demands for offshore renewable energy (ORE) yet high risks have impeded faster development. While the cost of generated energy has just been reduced to £100/MWhr for offshore wind in the UK (4 years ahead of government schedule) deployment further offshore will increase both the capital and operational & maintenance (O&M) costs. in China, onshore wind power is severely curtailed due to crowded transmission corridors. Exploitation of offshore wind would better match the population distribution in China, and so hence there is a strong motivation to exploit this ORE. In order accelerate this development, new technologies are desperately needed to improve the performance in terms of cost, efficiency and reliability (availability). In addition to offshore wind, other forms of marine renewable energy will also play indispensable roles in the future renewable energy mix. Because these technologies are less mature, this development involves even higher risks. As yet none of the wave energy generation companies have shown to be commercially viable without economic support mechanisms. Recognising the high risks involved and the development work that is urgently needed in the industry, this project aims to carry out fundamental modelling and validating work that will lead to the capability of virtual prototyping. Such a capability will significantly accelerate and de-risk the development work in industry. Complementary expertise in the two countries are combined to address the requirements of overall system performance from ORE devices (wind and wave) to grid, and focuses on the critical technical aspects that will dictate the design decisions. This will be achieved through multiple scale (dimensional and time-wise) and multiple resolution modelling, taking into account the specifications and utilisation of materials and components in the designed systems subject to optimal control. The modelling will cover the manufacturability of the designs and will consider environmental constraints including impact on sea life in different locations. These will be important as ORE development is scaled up in the future. The outcome of research will be demonstrated through a series of case studies including both systems for large wind farms and wave arrays, and also small scale devices supplying energy to off-grid islands. The project members have long track records in modelling and design of components in wind and marine renewable systems. The project allows the researchers to interact and carry out studies cutting across the borders of different engineering disciplines, enabling hi-fidelity modelling and virtual prototyping.

The microclimate parameters in urban areas have important impacts on the energy performance of buildings and the potential of passive cooling measures. For example, the urban heat-island (UHI) effect results in increased local atmospheric and surface temperatures in urban areas compared to the surrounding rural areas. Thus, the UHI will increase the overheating risk and the peak cooling load of buildings. It may particularly have a negative impact on night cooling strategies within the UHI during periods of hot weather. Effective urban planning and building design can have a beneficial effect on the urban climate and contribute towards reducing the intensity of the urban heat island, which improves the conditions in living spaces as well as directly reducing the peak cooling load of a building. The vision of the proposed project is to develop a practical, robust, urban thermal simulation method by using Digital Element Model (DEM) to store urban building geometry and boundary information and integrating it with the coupled thermal and airflow model. The DEM is a compact way of storing 3D information using a 2D matrix of elevation values; each pixel represents building heights and can be displayed in a grey-shaded digital image, which has a grey-level proportional to the level of the urban surface. The DEM is capable to handle large amount of data in less time. It is also able to present the geometrical relations among the buildings in the studied area. It has been proven to be an effective way of urban analysis. This model will be used to perform parametric study for various configurations of urban form and texture, building and road surface materials and vegetation in order to analyse Urban Heat-Island (UHI) mitigation strategies and potential passive measures of energy-efficient buildings. The principal objectives of this proposed three-year project are: (1) To develop a dynamically coupled thermal and airflow urban model integrating with the Digital Element Model (DEM), and to validate the model in association with experimental investigations in the urban canyon; (2) To link the proposed numerical urban model with the existing thermal and airflow building model (developed by the PI) to conduct an analysis of the interrelationship of the urban microclimate and building energy performance; (3)To perform an urban parametric study and analyse the potential of UHI mitigation strategies and their impact on the urban environment and energy consumption (CO2 emission) and (4)To assess urban and building thermal comfort. The prospected deliverables are: D1: A coupled thermal and airflow urban dynamic model integrated with the Digital Element Model (DEM) together with a series of numerical and visualised simulation results of different urban configurations for urban environment analysis; D2: A integrated urban microclimatic and building energy simulation model; D3: A series of parametric assessments for the urban environment and the potential of UHI mitigation strategies and D4: A series of assessments for passive measures of energy-efficient building design in the urban context.

The Chinese 11th Five-Year Plan considers Sustainable Energy Supply and Sustainable Built Environment as crucial for achieving sustainable development. Recognising the potential benefits, the UK government has actively encouraged international collaborations with China. Two Engineering Schools at Queen's University Belfast (QUB), with internationally recognised research excellence in the Built Environment and in Electric Power & Control, have taken used these opportunities to collaborate with a number of, geographically distributed, leading Chinese universities, research institutions and industries. This effort has been supported by the EPSRC, the Royal Society & the Royal Academy of Engineering, and includes a 1M EPSRC grant for a UK-China joint consortium on sustainable electric power supply and a 220K EPSRC project to run UK-China Network of Clean Energy Research to promote SUPERGEN (Sustainable Power Generation and Supply) in China. Some QUB technologies have also been tested in major construction projects, such as the Beijing National Olympic Stadium (Bird's Nest) and the Hangzhou Bay Sea-Crossing Bridge (longest such bridge in the world). The applicants aim to enhance their science innovation and technology transfer activities in both China and the UK helped by their 7 university partners (principally Tsinghua University, # 1 in China & Zhejiang University, #3 in China, the others being Chongqing, Shanghai Jiaotong, Southeast, Shanghai and Hunan), 3 Chinese research institutions (Central Research Institute of Building & Construction CRIBC, the Chinese Academy of Sciences Institute of Electrical Engineering, and the Research Institute of Highways). The China State Railway Corp. (largest under Ministry of Railways), the China State Construction Corporation (largest under Ministry of Construction), Bao Steel Corporation (largest in China, #6 in world sales) and Shanghai Electric Group (largest in China) are the main 4 Chinese industrial partners. Complementary UK support includes Amphora NDT Ltd, Macrete and SUPERGEN.

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.

The aim of this network is to bring together interdisciplinary expertise to address the problem of air quality in schools. The future health of our nation and indeed all human society depends on educating children in healthy environments. The Tackling Air Pollution at School (TAPAS) network focuses on that vulnerable section of every society - school children and their environment. Our vision is to create and develop a menu of options that can be introduced into schools to provide an environment free of pollutants and in harmony with nature, so that children have a fulfilling and healthy educational experience. These products need to be effective, inexpensive and, where possible, educational: i.e. they should involve the children in an understanding of their environment and provide them with an opportunity to engage with it in social, scientific and behavioural terms. We have chosen to focus on schools and school children for the following reasons. Children are a particularly vulnerable section of society. They are physiologically less able to regulate their temperature and are more susceptible to exposure to air pollution than adults. Among the vulnerable groups in society school pupils will experience the impact of poor air quality for the longest period into the future. Recently, over 2000 schools in the UK were identified as being in 'pollution hotspots' where air pollution exceeds WHO limits. From a practical viewpoint, working in schools has many advantages. School keep records on student attendance and pupils which provide information on absences related to health. They also have data on room occupancy, pupil activities (e.g. PE, meals) and movement through the school. This information is essential to determine personal exposure. Additionally, schools offer a wide variety of spaces including labs, meeting halls, dining areas as well as classrooms, each with different ventilation and indoor sources of pollution. The ability of schools to mitigate exposure to pollution is hampered by lack of knowledge. For example, the impact of idling vehicle engines near school while dropping off and collecting children on exposure in the playground or on indoor levels of NOx and particulate matter (PM) is unclear, making it impossible for schools to decide whether to ban idling or not. Our interdisciplinary team consists of experts in indoor and outdoor pollution, air pollution modelling, data science, building design and ventilation, education, social behaviour and health impacts. This will allow this network to address the critical issues associated with pollution in schools by offering a menu of solutions. We also propose to include a significant educational component so that pupils will learn about the impacts of poor air quality and take this knowledge with them as they grow up, thereby producing a lasting change in society. Schools also accommodate children with special educational needs and disabilities (SEND) who are even more vulnerable and who often require special environmental conditions. Furthermore, there are currently a wide range related activities concerning indoor environmental quality in schools that this network will bring together for the first time in a coordinated fashion.
