Summary of the impact

Research at the University of Nottingham into the use of phase- change materials as a means for heating and cooling buildings has resulted in the development of COOL-PHASE®, a product which is sold by Monodraught ltd. The system was launched in 2008 and has been installed in 136 buildings in the UK. COOL-PHASE® underpins the long-term growth strategy for the company and Monodraught has invested in employing 3 new staff and £250k in capital expenditure to make the unit suitable for mass production.

Summary of the impact

The Lighting Group has been involved in the formulation of national and international design guidance, with impacts on the practices of the UK and international lighting industry.

This guidance offers designers the tools to create optimum visual conditions in energy efficient buildings while reducing electric lighting usage. This involves three areas:

1. The development of lighting design in interiors to take account of room contents;
2. Involvement of the occupant in the control of light levels and electricity usage; and
3. The replacement of electric lighting with guided daylight systems.

The main impact of the work is its influence on the body of professional practice relating to interior lighting design. This guidance advocates the creation of user friendly visual conditions, low electricity usage and natural light in areas remote from windows.

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 undertaken at the University of Cambridge Department of Applied Mathematics and Theoretical Physics (DAMTP) was the first to demonstrate that low-energy systems could be modelled in the laboratory and that the complex ventilation flows within buildings could be represented accurately by simple algorithms. These algorithms were implemented as a series of `low- energy' modules in the US Department of Energy whole-building simulation code EnergyPlus. EnergyPlus is used worldwide for building energy simulation and the user group currently has 3144 members. The use of this code has led to optimised design of a number of buildings, such as the New York Times HQ in Manhattan opened in 2009.

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

The impacts of this study by the Mackintosh Environmental Architecture Research Unit (MEARU) with two other research units arise from auditing and analysing domestic laundering (100 homes surveyed), and positing solutions to mitigating `fuel poverty' (energy cost >10% disposable income) and improving health-linked aspects of indoor air quality — identifying direct and indirect energy usage attributable to laundering, and the detrimental environmental consequences of added humidity. Impacts since completion in 2012 relate to public engagement — meetings with a key regulatory body, dissemination events and a successful publicity campaign at regional, national and international level, marking the launch of a Design Guide.

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

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 by Raynham et al has led to the adoption of white light in residential roads and city centres throughout the UK, enabling an energy saving of 30-40% while providing better quality of street lighting. As a result, today there are now c.1,200,000 conventional street lights with white light sources and a further c.220,000 LED lanterns that emit white light. Conservative estimates suggest that this changeover to white light saved 113 GWh of electricity in 2012, and thus reduced the UK emissions of CO₂ by 45.5 megatons.

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.
