Abstract

The use of near surface geothermal energy (borehole heat exchangers and heat pump) for heating can save energy and reduce CO2-reduction if the borehole heat exchangers are properly designed. The required length of borehole heat exchangers depends on the thermal conductivity of the underground. An approach for an assessment of thermal conductivity by geophysical techniques (resistivity and NMR) is discussed in this paper.
