Energy Management of existing non-domestic buildings is wrought with many challenges, a number of which arguably exist due to the diversity found amongst individual buildings and amongst the humans who occupy them. Buildings are inherently unique systems making it difficult to generalize technology solutions for any individual property. Instead, to make robust investment decisions for the energy-efficient upkeep of a particular building requires some degree of tailored engineering and economic analysis. To understand why this is the case, one need only to consider the chain of questions one would likely need to address for decision-making in an arbitrary building. For instance, we might ask: what is the age of the building and the equipment currently installed in it? Does the heating system need to be replaced? If yes, is the current system a boiler, and if so, how efficiently does it perform? Would the building benefit from a new boiler or an electric heat pump? Would it benefit from replacing the heating distribution pipes? Do the cost / benefits of any of these technologies depend on government tariffs and subsidies? What is the risk faced if any available subsidies are cut in the future? How robust is either technology to the future price of natural gas and electricity? Would that risk be worth taking? Is it too expensive to even start thinking about the options and associated risks? How would a facility manager visualise the options available and possible spreads of benefits and risks for all these aspects? This project aims to respond to these challenges. Indeed, in order to make sound decisions on future building operation and technology investment, evidence shows that one needs adequate information on a number of engineering, economics, and social science matters pertaining to each individual project. To obtain this information has so-far been viewed as a costly exercise, and has contributed to the general perception that undertaking deep cuts to building energy consumption (achieving more than 15% in energy savings per investment) is an economically risky affair. This proposal is the first to develop and recommend an altogether new approach to performing building audits, energy simulation, uncertainty analysis, data visualization, and finally investment decision-making. It will lead to a marked reduction in the cost of acquiring information for robust retrofit and facility management decisions. The direct outputs of this project will be a series of software tools for three distinct but related purposes: (i) collecting building data on relevant uncertainty parameters (i.e., "what do we know now?"); (ii) propagating and quantifying uncertainty using building simulation models, measurements obtained from key monitored building sites, and cutting-edge statistical approaches (i.e., Bayesian analysis); and (iii) the display and interpretation of uncertainty. During the course of the project, workshops will be organised to lay out the current (uncertain) knowledge that has been, until now, largely undocumented in the buildings sector and inaccessible to the energy research community. This includes gaining understanding on the most common faults observed in managing conventional energy systems, and how spatial layouts in building evolve. The graphical presentation of risk information and understanding users' perception of uncertainty and risk will be key elements of these workshops and the research programme. Our software tools, user guidance, and numerical runs of test cases will be made available, as the web-based B-bem portal, via the University of Cambridge web site.

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.
