Summary of the impact

Alliance researchers have demonstrated that it is possible to refurbish existing buildings, which make up over 90% of our stock of over 26m buildings, to achieve a reduction in CO₂ emissions of up to 80% (domestic properties) and 50% (non-domestic). The research has underpinned a shift of emphasis by UK government from new to existing buildings and the formulation of incentives to encourage building owners to make energy-saving improvements. In partnership with not-for-profit, public and private stakeholders, it has been used by national and local agencies to highlight the potential of improving the energy performance of traditionally constructed, timber-framed and residential mobile homes and incorporated into practical guidance by the Chartered Institution of Building Services Engineers. It is also the technical foundation for an educational software package developed with 100 school children and teachers and praised as exemplary by Education Scotland.

Summary of the impact

Research at Loughborough University during the period 2008-2013 in the areas of control, commissioning and design of advanced naturally-ventilated buildings has led to:

• Improvements in ventilation performance in an award-winning building in the USA;
• Confirmation of the performance of a globally applicable low-energy building design strategy; and
• Increased confidence in US design teams to produce naturally ventilated buildings.

A subsequent KTP project with SE Controls has led to:

• A new product range for a UK controls company;
• Increased turnover;
• Expanded capacity to exploit research for innovation; and
• Stimulated growth of its new product development team.

Summary of the impact

A development of six Creative Energy Homes (CEH) on the University of Nottingham campus provides a living test-site for leading firms, including E.ON, David Wilson Homes, BASF, Tarmac, Roger Bullivant and Igloo Blueprint to work with the University of Nottingham to investigate the integration of energy efficient technologies into houses. As a result of this work, Lovell homes has won a number of sustainable housing contracts, Roger Bullivant have developed and installed 30 SystemFirst™ foundation systems and Igloo Blueprint have built £7M worth of new homes. The research findings have informed the UK Government's "Green Deal" strategy, the Nottingham Community Climate Change Strategy and received widespread acclaim through a number of public engagement activities reaching out to over 5 million people.

Summary of the impact

Research at the University of Southampton, into the engineering of complex socio-technical systems, has underpinned new technologies in the area of intelligent energy management, and made Professors Nick Jennings and Alex Rogers trusted sources of advice for energy policymakers, key stakeholders and industrial researchers. The work has had an economic, environmental and societal impact: it has shaped R&D strategies of leading British companies like BAE Systems and Secure Meters; the launch of iPhone apps and websites have supplied private and industrial users with personalised data regarding their energy use, resulting in cost savings and reductions in carbon emissions; it has enabled charities to provide energy-saving advice to households directly; and has won an international technology showcase competition leading to a spinout and commercialisation of research.

Summary of the impact

Professor Gupta, an internationally recognised expert on architecture and climate change, has developed an innovative software model for carbon counting (DECoRuM® model) and climate change adaptation (DECoRuM® adapt) of existing housing. The combination of Geographic Information System techniques, energy efficiency and climate change adaptation measures has enabled DECoRuM® model to provide a range of environmental, public policy and practice benefits to homeowners, communities, local authorities and architects. These benefits have been realised through refined global common carbon metrics promoted by UNEP, BSI standard and industry guidance, as well as achievement of real energy and CO2 emission reductions from low carbon refurbishment, leading to improved building energy performance.

Summary of the impact

This case study describes the national and international impact of research undertaken by Professor Chao, as part of an EU funded Framework 7 project, Digital Environment Home Energy Management Systems (DEHEMS). The project has improved existing household energy monitoring, tackling the issues of global warming and CO₂ emission reduction in the domestic sector. The research has directly contributed to the development of a product called EnergyHive, subsequently marketed by Small to Medium-sized Enterprise (SME) Hildebrand Ltd, who was the industrial partner in the DEHEMS consortium. The research has delivered the following:

• Economic impact — as a direct result of the research project, Hildebrand Ltd has diversified and entered into an entirely new market;
• Impact on the environment — home owners, local authorities and energy companies have installed EnergyHive meters which have shown significant energy and carbon dioxide reductions.

Beneficiaries of the research and the subsequent impact include: a commercial business, domestic energy consumers, UK and international energy companies and local authorities.

Summary of the impact

Roy Alexander's innovative research into climate change awareness and behaviour change has transformed the way the world looks at this issue.

It has enabled a Cheshire village to reduce its domestic carbon footprint by 20% and become an established model for communities across the globe. Dissemination of his research has reached around a billion people worldwide and stimulated the establishment of similar projects across the UK, and as far afield as Canada.

The award-winning initiative has influenced local and national government policy and attracted official visits from the Secretary of State for Defra, the Rural Advocate and Business in the Community.

Summary of the impact

The work described here has impacted on European policy and standards concerning energy efficiency in Building Services.

The impact arises from two Welsh School of Architecture led and European Commission funded projects, HARMONAC (focussed on inspection of air-conditioning systems) and iSERV (focussed on automatic system monitoring and feedback). These pan-European projects demonstrate achieved energy savings of up to 33% of total building electricity use in individual buildings, and potential savings up to €60Bn. These projects demonstrably impacted the recast European Energy Performance of Buildings Directive (EPBD) and the revision of EU Standards (European Committee for Standardisation (CEN)).

Summary of the impact

Research conducted by Professor Short in the use of natural ventilation and passive cooling in non-domestic buildings is altering policies and plans in the refurbishment of existing healthcare buildings and in new-build for acute and primary care, both within and outside the UK. Moreover, the massive demolition and replacement of healthcare building stock, presumed to be required to simultaneously adapt to the increased ambient temperatures due to climate change and mitigate carbon emissions through improved energy efficiency, has been shown to be unnecessary.

Summary of the impact

The research reported in this case study demonstrates that in order to achieve a carbon neutral future whole life building carbon footprinting should be undertaken by using Life Cycle Assessments (LCA) at all stages of design, construction and throughout the lifespan of buildings. Practical tools in this area are few, and the award winning research projects reported here address this need and have had impacts in the following areas; firstly, through their direct applications in building procurement and management, secondly through changes to national standards and specifications and thus professional practice, and thirdly through enhanced public awareness at local, national and international levels.
