Biography

Introduction

Dr Mohammed Salah-Eldin Imbabi, BSc (Hons), MSc, PhD is a scientist, professional engineer, innovator and educator in the diverse fields of civil engineering, low energy building engineering, energy efficiency and renewable energy. He is Associate Editor and member of the Editorial Board of the International Journal of Sustainable Built Environment (IJSBE) and author of more than 100 peer-reviewed scientific journal articles, proceedings papers, patents and reports.

Major sponsors of Dr Imbabi’s research include the Engineering and Physical Sciences Research Council (EPSRC), Scottish Executive, the Carbon Trust and Industry. He currently manages £3.62 million of external research funds and leads a large international multi-disciplinary research team. This level of activity contributed to the creation in February 2013 of a new Centre for Innovative Building Materials and Technologies (cibmt) at the School of Engineering, to serve as the focus of activity and expertise in all aspects of building engineering, building energy efficiency, building materials and emerging novel building technologies across the University. Dr Imbabi is a Founding Director of this Centre. He is also a member of the steering group of Mainstreaming Innovation, a project involving 9 Scottish Universities and supported by the Scottish Government to promote innovation in construction. The project has been a year in the making and launched in April 2013. He is additionally a member of the Technical Advisory Group of the Renewable Energy Foundation (London), the International Advisory Council of the World Renewable Energy Network's (WREN), IEA Task Force 44 on ‘Integrating Environmentally Responsive Elements in Buildings’ and the 2006-2010 and 2010-2014 Engineering and Physical Sciences Research Council (EPSRC) Colleges.

Dr Imbabi’s engagement with industry however extends significantly beyond this and includes the creation of Energyflo Construction Technologies Ltd (ECT), a University of Aberdeen spin-out company that was set up in 2004 to commercialise his research in the field of Dynamic Insulation (DI).  As Executive Chairman, and subsequently while on secondment to the company as Technical Director between September 2008 and December 2010, Dr Imbabi led the recruitment of key personnel and secured multi-million pound venture capital investment in the company.  ECT has won numerous prizes and accolades and recently gained formal recognition for its EXstream™ range of DI products in the UK Building Regulations, under his guidance, through SAP Appendix Q (for domestic buildings) and a new Dynamic Simulation Modelling (DSM) methodology (for commercial buildings). ECT products have been licensed for manufacture and sale by Jablite and SpeedDeck in the UK. The company is a clear example of the beneficial impact of research and innovation in strengthening economies and improving the quality of life for communities everywhere. Its creation defines 1 of 5 Impact Case Studies in Engineering that are being taken forward by the University in REF 2014. Dr Imbabi’s current focus includes the next generation of passive, low-cost Void Space Dynamic Insulation (VSDI) systems that will facilitate the mass deployment of this important technology.

In 2013 Dr Imbabi was invited to be a member of the judging panel and chair of the green building sub-panel at the Homes for Scotland (HFS) 2013 Awards. HFS, in Edinburgh, is the organisation representing the country’s private home building industry.

Research Impact Case Study

 

Dynamic Insulation in Buildings

Impact case REF3b; Unit of assessment: 15, General Engineering

Advances in the science of Dynamic Insulation (DI) by Dr Imbabi and members of his research team at the University of Aberdeen have contributed to international efforts to combat climate change, through reduction of the carbon emissions associated with the heating, ventilation and air conditioning of buildings.

Following the spin-out of Energyflo Construction Technologies Ltd (ECT) and development of the world’s first modular DI product (the Energyflo™ Cell - see below), jobs have been created and developers have been able to use the first commercially available DI products, to improve the energy efficiency of buildings and meet strict new environmental targets.

ECT has secured more than £2.5 million of venture capital investment and, in the UK, it's EXstream™ dynamic insulation technology has been licensed for manufacture to Jablite (walls), SpeedDeck (roofs) and A Proctor Group (frames).
