Future Research

Dr Mempouo has a particular interest in Low Carbon Buildings, the techniques and applications those enhancing building energy efficiency and heat pumps performances and the heat storage of solar thermal energy in the ground or in the PCMs. He always wanted to pursue an research career in the low carbon technologies and sustainable buildings fields.

Short term goals: I plan to continue my research on Sustainable Energy Technology and Low Carbon Building and its effect on the built environment. By extending it not only for office buildings in the UK, but also for other building types including industrials, and also for areas in Europe and possibly the other leading cities in the world. I'm also interested in the integration of energy efficient, innovative technologies in the renovation of public buildings in a range of different climatic conditions that will produce a step change in building performance while providing enhanced working and living conditions within buildings. I will employ dynamic multiobjective building physics models to analyse current structures, carry out simulations involving alternative renovation technologies and find optimum solutions for each building taking account of the building use, climate and how this would affect heating/cooling in buildings, while significantly reducing energy consumption and hence global warming. It is hoped that some outcomes of this work will be useful as standard in for retrofitting of a non-residential building, and can be incorporated into Energy Institute (EI) Guides in the future. I also intend to continue working on my project in Sustainable Agri-Tech with seven industrial partners including Unilever. This project will allow me not only to continue with research work, but also gives a valuable link with consultancy companies and contractors, so I'm always up-to-date to what is happening in the industry, and to keep up to date with the topics of greatest concern (Sustainable Food and Drink Supply Chain in the UK and beyond). I would also continue to attend regularly project meetings, international conferences, and contribute when possible to events and presentations of Energy Institute East-Midland branch.

Medium term goals: My medium-term research interests lie in a novel Ground Heat Exchanger (GHE) and Heat Transfer Enhancement Techniques for Ground Source Heat Pump. The overall aims of the project are to investigate the technical and commercial feasibility of a novel technology that would enable Ground Source Heat Pumps (GSHPs), powered by low carbon energy sources to become economically viable for a broad range of space heating applications. It creates a new commercial opportunity for UK industry addressing fuel poverty by making space heating cheaper. I am also planning to seek fund through the Innovate UK so that the lab prototype will move to the demonstrator and scale up to create a commercially acceptable version. I also aim to be climbing the ladder in academia and become a lecturer in Sustainable Technology and Low Carbon Buildings. This would allow me to pass on my expertise in the field and at the same time, allow me to continue doing research. I also aim to keep having links with consultancy Industry companies and contractors and to conduct research for the industry on topics that require investigation. Long term goals:

My long-term goal is to become a self-sustain research leader, with the advantage to build a long-term (5-10 years) career growth as a Professor in Sustainable Energy Technology (SET) and Low Carbon Buildings (LCB). I have also been working as Consultant / Advisor with UN-Habitat and IFDD (the Francophone Institute for Sustainable Development) in a range of development and implementation programs aligned to the Sustainable Building Codes for Africa Countries. The future of our field will probably be dominated by sustainability issues including energy and resource efficiency. And How buildings can help to adapt to climate change in a range of different climatic conditions and how to mitigate its effects on occupants, so I can see my future being involved in tackling these problems in the UK, and Africa. My activities will aim to provide an enabling framework for the SET/LCB initiative to thrive in the African cities, and to provide communities leaders and municipalities with feasibility and planning tools for energy-from-waste strategies that link up integrated waste management, sanitation planning, energy crisis resilience and the implementation of the 2030 Agenda for the 17 Sustainable Development Goals (SDGs), particularly SDG 7, SDG 11 and SDG13 in Africa.
