Professor Simon Rees


Following the Award of a Bachelor of Technology in Mechanical Engineering from Loughborough University in 1987 Simon Rees joined the consulting engineering firm Ove Arup and Partners as a Mechanical Building Services Engineer. In 1994 he began research into Displacement Ventilation and Chilled Ceiling systems in the Civil and Building Engineering department of Loughborough University resulting in the award of a PhD in 1998. He has since spent more than five years as a Visiting Assistant Professor at Oklahoma State University in the USA. In this capacity he undertook research into ground source heat pump systems and numerical simulation of thermal systems. He joined the Institute of Energy and Sustainable Development at De Montfort University in 2003 to continue his work in low energy thermal systms, building heat transfer and fluid flow and energy simulation and to develop an innovative MSc programme. He joined the School of Civil Engineering at the University of Leeds in 2015.

Research interests

Simon Rees's research interests are in the field of Building Engineering Physics and geothermal heating and cooling systems. These interests can be summarised as sustainable buidling design, energy simulation and dynamic thermal modelling methods, room heat transfer, thermal networks and geothermal systems. The most significant theme of his work has been geothermal heating and cooling systems.

Current work includes modelling of advanced borehole heat exchanger technologies and foundation heat exchanger elements (energy piles and activated walls). This work is being undertaken in the Horizon 2020 project GEOTeCH (Geothemal Technology for Economic Cooling and Heating). Other work includes performance analysis of large ground source heat pump systems, analysis of urban wind energy potentials, urban-scale solar irradiation mapping and application of Dynamic Thermal Network approaches to modelling of thermal networks and ground thermal energy storage.
