The CBES group at the UCL Bartlett School of Graduate Studies received its Platform Award in 2006 and the funding has facilitated a period of sustained success. Platform funding has been of critical value in helping us to retain key staff, to innovate and in providing the flexibility to be adventurous. We have also been able to enhance our knowledge exchange/transfer work and international collaboration. This has been reflected in the quality, growth and range of our activities. The Platform funding thus enabled us to establish a multi-disciplinary, world-leading research group which has dramatically increased in size, resulted in world leading academic publications, seeded a new Institute (Energy), developed new methods of interdisciplinary and systems working and won international prizes. CBES was submitted to and awarded the highest percentage (35%) of world leading rated researchers of any UK university in the 2008 Research Assessment Exercise (RAE) - Architecture and the Built Environment Panel. Building on the work directly supported or indirectly facilitated by the current Platform Grant, and also responding to new opportunities, the strategic direction of this continuation proposal represents a step change for CBES. During the period of the current Platform Grant, CBES was primarily interested in developing multi-disciplinary solutions to the practical problems of designing, constructing and managing environments within and around buildings. In the next quinquennium we will strengthen our world-leading position. We propose a strategic programme of activity in a timely new research direction - the unintended consequences of decarbonising the built environment . We aim to transform understanding of this urgent issue that will have enormous impact internationally.In order to predict the possible future states of such a complex socio-technical system, conventional scientific approaches that may have been appropriate for systems capable of being analysed into simple components are no longer applicable. Instead, we need to bring radically new approaches and ways of thinking to bear. We need to develop and extend our multi- and inter- disciplinary ways of working and be informed by modern complexity science. The initial Platform grant has helped set up a group that includes building scientists, heritage scientists, economists, systems modellers and social scientists. The renewal will enable the group to focus on this urgent problem, to develop appropriate research methods and help develop real-world solutions within the required timescale. The number of Investigators has increased from 11 at the start of the existing Platform Grant to 13 in the renewal - a vital expansion to enable the inclusion of a wider range of disciplines. Nevertheless, facilitated by Platform funding, we will now need to form a whole new set of additional alliances to support the development of our proposed work.One of the key achievements of the current Platform Grant has been the spinning off of the newly formed UCL Energy Institute (EI). CBES is thus ideally placed to benefit from the extensive and diverse range of energy demand reduction work at the EI. However, the EI is not funded to study unintended consequences and this Platform renewal will thus perfectly complement EI activity. Via Platform funding and in partnership with the EI, CBES aims to develop a new concentration of world-leading research excellence in this field. We will establish a regional hub for research collaboration with local universities which will ensure that benefits from Platform funding are felt more widely than UCL alone.

The Innovative Construction Research Centre (ICRC) is dedicated to socio-technical systems research within the built environment, with particular emphasis on through-life performance in support of the client's business operations. Our vision is for a research centre that not only supports the competitiveness of the architectural, engineering, construction and facilities management sectors, but also supports societal needs for built infrastructure and the broader competitiveness of the UK economy. The domain of enquiry lies at the crucial interface between human and technical systems, thereby requiring an inter-disciplinary approach that combines engineering research methods with those derived from the social sciences. The ICRC's research portfolio is organised into six themes: (1) Integration of design, construction and facilities management. Concerns the through-life management of socio-technical systems within the built environment. Topics of consideration include: integrated logistic support, design for reliability and systems integration for building services. Of particular concern is the way that firms within the supply chain are integrated to provide solutions that add value to the client's business. (2) Knowledge management and organisational learning. Addresses the means of supporting knowledge flows across extended supply chains and the extent to which procurement systems learn across projects. Of particular importance is the design of learning mechanisms that extend across organisational boundaries. Also investigates the degree to which the construction sector can learn from other sectors, i.e. aerospace, automotive, retail, defence. (3) Human resource management and the culture of the industry. The construction sector is too often characterised by regressive approaches to human resource management (HRM) with little emphasis on developmental to support innovation. Of particular importance is the concept of 'high commitment management' that has emerged as a central component in the quest to link people management to business performance. Any attempt to improve HRM practices in the construction sector must also recognise cultural barriers to the implementation of new ways of working.(4) Innovative procurement. Includes legal, economic and organisational aspects of procurement systems. The last twenty years has seen a plethora of new procurement methods seeking to encourage different behaviours and allocations of risk. Many such initiatives experienced significant reality gaps between technological intent and resultant behaviours. Of particular importance in the current context is the notion of performance-based contracting which seeks to reward parties on the basis of building performance.(5) Innovation in through-life service provision. Most innovation in facilities management (FM) is concerned with service provision rather than the design and construction of the built asset. The inclusion of FM-service provision reflects the ICRC's strategic focus on through-life issues. The shift towards service provision is reflected in practice through procurement approaches such as PFI/PPP. But the issue has a wider significance as construction contractors increasingly embrace service philosophy. (6) Competitiveness, productivity and performance. Focuses on techniques for performance improvement, coupled with a broader emphasis on competitiveness and profitability within the marketplace. Techniques for performance improvement include: process mapping, benchmarking, value management, risk management and life-cycle costing. Also seeks to assess the competitiveness of the construction sector in comparison to other countries, and to achieve a broader understanding of the economic context within which firms operate.

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.

Research into the development and application of sustainable construction, renewable energy applications and energy management technologies, including their economic and social impacts, is the main thrust of the Centre. Attention will also extend to the way in which the adoption and use of such technologies can be enhanced through procurement and other policy levers. In particular, research in the Centre will be focused on the following two complementary themes:1. Sustainable building and services systems:The emphasis of this theme is on developing new concepts in the design, construction, operation and maintenance of sustainable building and through-life service systems. The impact of climate change and the modelling of the local environment and its interaction with the built environment as well as sustainable procurement and the diffusion of innovative sustainable technologies will also be included. The aim is to achieve lower carbon emission in the construction and operation of buildings and their environmental control systems.2. Energy management in buildings and infrastructure systems:This theme concerns the integration of low- to zero-carbon energy generation systems in buildings and infrastructure systems, demand management technologies (e.g. smart meters, consumption feedback devices, utility load management), and building energy management technologies. The theme addresses the systems integration of sources of supply, demand and storage within a geographically defined area to achieve local area supply-demand matching. The emphasis will be on analysis, integration and management of existing energy technologies at the site scale and the factors governing their adoption within the construction industry.These activities will be delivered with the supporting research areas below:- Climate, climate change and the built environment- Sustainable materials and structures- Innovation, design and sustainable technologies- Informatics for sustainable technologiesA key aspect of this proposal is that the EngD training programme should be sufficiently flexible to cater for the varying needs of the Research Engineers (REs) who will be based in industry, but employed by the University. In addition to the research programme, candidates will undertake a mixture of core and elective modules, some of which are currently offered in the University for PhD research students and existing MSc programmes. The taught programme will be an integral part of the EngD programme and supports the research that the REs will be carrying out at the sponsoring companies. The taught programme is planned to fulfil the following objectives:- Provide up-to-date knowledge of the relationship between engineering research, innovative technologies, and sustainability with emphasis on application to the built environment and energy management.- Deliver professional development in management and business skills that are necessary for dealing with constantly changing legislative environment particularly in relation to energy utilisation.- Fill any knowledge gaps that may arise from the research project.The training will be carried out with the full collaboration of the companies sponsoring the research engineers. The participating companies are also expected to contribute to an enhanced stipend to attract the best talent. The Research Engineers will be registered full-time on the EngD degree course.

We spend some 90% of our time inside buildings where we control the quality of the environment for health, thermal comfort, security and productivity. The quality of the indoor environment is affected by many factors, including design of buildings, ventilation, thermal insulation and energy provision and use. Maintaining the quality of the environment in buildings can have considerable consequences on both local and global environment and on human health. In recent years, the air-tightness of buildings has become an issue, as part of a drive to provide thermal comfort and reduce energy consumption. However, as dwellings are made more airtight, internal pollution sources can have a greater impact on the indoor air quality and occupants may experience adverse health effects unless ventilation is effective. On the other hand, ventilation can lead to ingress of outdoor air pollution; it also reduces energy efficiency of buildings, accounting for 25-30% of the total building energy use. Conversely, efforts aimed at the improvement of energy efficiency through better thermal insulation may affect adversely indoor air quality, e.g. through reduced ventilation and increased moisture content. The latter is the main cause of mould, the exposure to which is being increasingly linked to respiratory and other health problems. Further, burning fuels in micro-generation domestic appliances such as gas boilers and cookers can potentially be hazardous to the health of those in the dwelling or further afield. However, switching to other sources of energy such as biomass, photovoltaics, fuel cells etc., while reducing the impact on the indoor environment can, on a life cycle basis, cause environmental and health impacts elsewhere. Nevertheless, several Government reports have highlighted the importance of household micro-generation options as well as energy efficiency, given the imperatives for reducing greenhouse gas emissions and widespread fuel poverty. The latter has been linked to Britain's large burden of cold-/winter-related deaths, which often exceed 30,000 per year. Poor indoor environmental quality in residential buildings, offices and schools has been related to increases in sick building syndrome symptoms, respiratory illnesses, sick leave and losses in productivity. Health effects can be immediate (e.g. irritation of the eyes, nose, and throat, headaches, dizziness and fatigue) or can occur over a longer period of exposure to indoor pollutants (e.g. respiratory diseases, heart disease and cancer). A growing body of scientific evidence indicates that the air within homes and other buildings can be more seriously polluted than the outdoor air in even the largest and most industrialised cities. Given that most people spend approximately 90% of their time indoors, their exposure to air pollutants is determined primarily by exposure indoors, particularly in their home. In order to contribute towards achieving a better quality of the indoor environment, this project proposes to study the environmental and health effects related to the generation, conservation and use of energy in buildings, with a particular focus on residential buildings. The main outputs from the project will be an integrated decision-support methodology and software tool for more sustainable management of indoor pollution. The framework will be applied to a number of case studies that will compare environmental, health and economic implications of the principal options for future home energy provision as an aid to policy development. Using a life cycle approach, the project will examine a range of sustainability issues, including environmental impacts (e.g. resource depletion, global warming, acidification, eco-toxicity etc.) and social issues (e.g. human health, comfort and well-being). The economic implications of different options will also be examined.
