The proposed research explores the significant challenge which the carbon reduction agenda poses for UK house builders. Focusing on the development of new products and processes at the project level and their diffusion across a large multi-regional firm we will ask key research questions that include: How can construction firms take advantage of project-level innovations? How can they meet the challenges which progressive carbon reduction targets currently pose? How do these innovations travel across large, complex firms? And how do standards shape innovations and how do innovations feed into ongoing changes in standard practice? The proposed research explores these questions by examining the development, uptake and diffusion of technical innovations from Hanham Hall, an experimental housing development which Barratt Developments has used to address the 2016 requirement that all new homes meet a zero-carbon standard. Barratt Developments is one of the largest house builders in the UK. The house builder has four brands and had an average of around 400 active sites at any one time across 25 divisions. The question of how specific technical innovations from Hanham Hall are being diffused and stabilised across Barratt Developments addresses some of the core challenges for the mainstreaming of zero-carbon standard buildings. While many scholars highlight the challenges of cross-project learning and the diffusion of innovations, little empirical or theoretical work has been done on the 'anchoring of innovations' at the firm-level. Similarly, little work has been done on the travel of innovations across projects within a large, multi-regional firm. This problem is especially pressing when one takes into account the ambitious upcoming carbon reduction targets and the largely organisational nature of the challenge. As a number of observers have noted, the sector knows how to build low-carbon buildings on experimental developments; what it does not know how to do is to incorporate that know-how into standard practice. The research questions are informed by the application of actor-network theory and neo-institutionalism to the study of key technical innovations at Hanham Hall across Barratt Developments: (1) to identify and explain the development of a number of key product and process innovations at Hanham Hall in response to carbon reduction requirements; (2) to examine the impact of those innovations on firm-level practices (including supply chains, procurement, internal management systems, business models, policies and strategies); (3) to follow the introduction of those innovations into other Barratt Developments housing projects and to document similarities and differences in project-level accommodation to those elements; (4) to use this analysis to theorise processes of innovation, diffusion and stabilisation/institutionalisation (in firm-level strategies, systems and practices) within large, project-based firms; and, (5) to contrast the findings produced by the deployment of neo-institutionalism and actor-network theory in the study of a single complex empirical case. The focal case study research will draw upon the analysis of documents, relevant artefacts, in-depth interviews and observations. The analysis of these sources will allow the team to trace the associations and movement of people and objects across multiple Barratt Development sites.

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.

Reducing carbon emissions and securing energy supplies are crucial international goals to which energy demand reduction must make a major contribution. On a national level, demand reduction, deployment of new and renewable energy technologies, and decarbonisation of the energy supply are essential if the UK is to meet its legally binding carbon reduction targets. As a result, this area is an important theme within the EPSRC's strategic plan, but one that suffers from historical underinvestment and a serious shortage of appropriately skilled researchers. Major energy demand reductions are required within the working lifetime of Doctoral Training Centre (DTC) graduates, i.e. by 2050. Students will thus have to be capable of identifying and undertaking research that will have an impact within their 35 year post-doctoral career. The challenges will be exacerbated as our population ages, as climate change advances and as fuel prices rise: successful demand reduction requires both detailed technical knowledge and multi-disciplinary skills. The DTC will therefore span the interfaces between traditional disciplines to develop a training programme that teaches the context and process-bound problems of technology deployment, along with the communication and leadership skills needed to initiate real change within the tight time scale required. It will be jointly operated by University College London (UCL) and Loughborough University (LU); two world-class centres of energy research. Through the cross-faculty Energy Institute at UCL and Sustainability Research School at LU, over 80 academics have been identified who are able and willing to supervise DTC students. These experts span the full range of necessary disciplines from science and engineering to ergonomics and design, psychology and sociology through to economics and politics. The reputation of the universities will enable them to attract the very best students to this research area.The DTC will begin with a 1 year joint MRes programme followed by a 3 year PhD programme including a placement abroad and the opportunity for each DTC student to employ an undergraduate intern to assist them. Students will be trained in communication methods and alternative forms of public engagement. They will thus understand the energy challenges faced by the UK, appreciate the international energy landscape, develop people-management and communication skills, and so acquire the competence to make a tangible impact. An annual colloquium will be the focal point of the DTC year acting as a show-case and major mechanism for connection to the wider stakeholder community.The DTC will be led by internationally eminent academics (Prof Robert Lowe, Director, and Prof Kevin J Lomas, Deputy Director), together they have over 50 years of experience in this sector. They will be supported by a management structure headed by an Advisory Board chaired by Pascal Terrien, Director of the European Centre and Laboratories for Energy Efficiency Research and responsible for the Demand Reduction programme of the UK Energy Technology Institute. This will help secure the international, industrial and UK research linkages of the DTC.Students will receive a stipend that is competitive with other DTCs in the energy arena and, for work in certain areas, further enhancement from industrial sponsors. They will have a personal annual research allowance, an excellent research environment and access to resources. Both Universities are committed to energy research at the highest level, and each has invested over 3.2M in academic appointments, infrastructure development and other support, specifically to the energy demand reduction area. Each university will match the EPSRC funded studentships one-for-one, with funding from other sources. This DTC will therefore train at least 100 students over its 8 year life.
