abstract = {This paper presents a methodology and instrumentation system for the indirect
measurement of the thermal diffusivity of a soil at a given depth from measuring its temperature at
that depth. The development has been carried out considering its application to the design and sizing
of very low enthalpy geothermal energy (VLEGE) systems, but it can has many other applications,
for example in construction, agriculture or biology. The methodology is simple and inexpensive
because it can take advantage of the prescriptive geotechnical drilling prior to the construction of
a house or building, to take at the same time temperature measurements that will allow get the
actual temperature and ground thermal diffusivity to the depth of interest. The methodology and
developed system have been tested and used in the design of a VLEGE facility for a chalet with
basement at the outskirts of Huelva (a city in the southwest of Spain). Experimental results validate
the proposed approach.},
