Summary of the impact

The Welsh School of Architecture (WSA) is recognised internationally for its research in developing advanced computational numerical models for simulating the energy and environmental performance of the built environment. These models have been used by leading design practices in the design of major buildings and urban developments. This impact case study presents three models from this research activity that have been widely taken up by industry worldwide, namely, the `building energy' model HTB2, the urban scale `energy and environment prediction' framework EEP and the `building environment' model ECOTECT.

• HTB2 has been used by leading international practices in the design of over 100 exemplary low energy buildings, including Dubai's award-winning Lighthouse tower, and EMPA, the first zero energy office building in Switzerland.
• EEP modelling framework for urban simulation has been used to assess the energy performance of existing large estates, for example, for use in housing retrofit programmes, and, to plan low-carbon developments, such as the Gateway City in Ras al Khaimer. It is now accessible through Google SketchUp, a common design tool used by architects.
• Ecotect underwent significant development at the WSA before its sale to Autodesk in 2008, and by 2010 had over 2000 licenced users globally.

Application of the models, often linked (e.g. HTB2 is the numerical engine for EEP and is accessible within the ECOTECT framework), has resulted in extensive environmental benefits, through reductions in global CO₂ emissions. Additionally, there has been a marked impact on practitioners and professional practices, through new guidelines for major international developments (e.g. Pearl Island Qatar and the Chongqing Ba'nan Low Carbon Development).

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 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

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

Ground-breaking research in the field of Dynamic Insulation (DI) at Aberdeen University has contributed to international efforts to combat climate change through the reduction of the carbon emissions associated with the heating, ventilation and air conditioning of buildings. Through the establishment of a spin-out company and the development of the world's first modular DI product, jobs have been created and developers have been able to use the first commercially available DI products and systems to meet strict new environmental targets. The success of such projects has led to greater public awareness of the issues around global warming.

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

The Environmental Building Group (EBG) is making an internationally-recognised impact on industry practice using building performance simulation research to look at the relationship between building use scenarios and building performance. In particular, research in building energy data analysis and the prediction of the impacts of climate change on UK building stock has enabled: C3Resources to increase turnover by 28%, double its workforce and win new international clients; Cornish Lime to develop a new product; RTP Surveyors to increase service provision; and Lend Lease and Wates Construction to change their strategies in relation to what/how they may build in the future.

Summary of the impact

Developing renewable sources of energy has to go hand in hand with reducing energy demand through increased energy awareness and behavioural change. To this end a multidisciplinary consortium of researchers, led by Professor Christopher Howe (Biochemistry), have developed several biophotovoltaic (BPV) devices for off-grid electricity generation, and as educational tools. This has resulted in impact on commerce (i.e. the acquisition of a BPV spinout company by Ortus Energy Ltd in 2009 through share exchange), on society and culture (an award-winning `Moss Table' developed by the consortium, which incorporates BPV technology, has been exhibited internationally since 2011 and has received extensive international media coverage) and on educational practices (a prototype BPV educational tool for schools has been developed by Howe and colleagues in 2013 and trialled with 6th form students).

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

The supply of electrical energy to centres of demand is an increasingly important issue as our power generation sources decarbonise. Without innovation in our use of high voltage cables, security of supply to our major cities cannot be guaranteed. Our research has:

• Identified how outdated international standards governing the rating of power cables can undermine network performance.
• Developed improved rating methods which will save National Grid £1.2 million annually.
• Informed new international technical guides.
• Designed, in conjunction with major industrial partners, cables that optimise transmission for lower operational costs, minimise the risk of network failure and cut carbon emissions.
