Mohamad Kharseh, from Hama in Syria, was in 2002 appointed “the best engineering student in Syria”. He worked on the utilization of renewable energy for space conditioning. After his successful BSc in Mechanical Engineering and some years of teaching at Al Baath University in the city of Homs, he was awarded a Scholarship for his PhD studies at any university. He decided to study within the Renewable Energy Group at the Department of Civil and Environmental Engineering, Luleå University of Technology in Sweden. He started his PhD work at LTU in Feb 2007.

Nowadays the global energy consumption exceeds 14.7 E10 MWh/year. Annual carbon dioxide emission is 3.05 E10 ton. Consequently, to produce 1 MWh of energy about 207.5 kg of CO2 are emitted to the atmosphere. Heating/cooling systems consume about 30-50% of global energy consumption, i.e. 5.9 E10 MWh/year corresponding to emission of 1.22 E10 tons CO2/year.

The licentiate thesis, which it is the half-achieved work for the doctoral degree, shows the potential of using ground coupled heat pumps for heating and cooling, in order to save environment and energy. The study focuses on GSHP systems in the Middle East, which means that occurring climatic, geological, and hydro-geological conditions were used in the analyses. The aim of the Licentiate work was to:

* Investigate the potential of borehole systems for heating and cooling in the Middle East.

* Investigate how the ongoing (local) global warming affects borehole systems.

* Analyze the heat transfer process in the borehole and surrounding ground in order to improve the thermal characteristics of such systems.
