Mark Hewitt trained as an architect. He has been involved in award-winning research and development projects in building physics, thermal energy storage and energy-efficient buildings for many years. He developed the fundamental ideas behind Interseasonal Heat Transfer and acts as a geothermal consultant advising on ground source heating and cooling of buildings and de-icing of road surfaces.
As a Senior Lecturer in Architecture at the University of North London (1990-2000), he developed a post-graduate course focusing on building physics and architectural design. He has also engaged in a series of research projects looking at large scale energy effects in building fabric, Underground Thermal Energy Storage, Borehole Thermal Energy Storage and Passive Downdraught Evaporative Cooling.
Mark is a CABE enabler (Commission for Architecture and the Built Environment) for education, sustainability and low-energy design.
His work on green energy has been widely published, including the book City Fights-debates on urban sustainability.
Mark, the inventor of Interseasonal Heat Transfer, is featured on the IET Faraday film about Howe Dell School.
Mark also appears on the BBC London News clip on the Toddington Demonstration for the Highways Agency.
