The energy pile concept, which involves using piles as heat exchanging units for ground source heat pump (GSHP) system, have recently been proposed as a promising way of using shallow geothermal energy resource for cooling buildings to improve energy efficiency and reduce the heat island phenomena in Bangkok Thailand. The power rating of heat exchange capacity of the piles is one of the most important design parameters to consider when evaluating the feasibility of the system. In this study, a full-scale thermal response test was conducted on a spun pile equipped with a single U-loop with the power rating of 60 W/m, yielding the effective thermal conductivity of 3.3 W/m°C, while that on steel micro pile yielded the value between 1.49 and 2.01 W/m°C with power rating of 10W/m. Effects of possible thermal cycles on the compression of Bangkok sand was also investigated in order to evaluate any adverse effects of using piles on pile settlement.
