Abstract
Thermo-active ground structures represent low-energy and sustainable technology which is a clear priority for many countries. Heat transfer between such structures and the surrounding soil is understood to play an important role both in the overall thermal performance of buildings and in the evolution of stresses in structural elements and the surrounding soil. This paper presents an overview of recent research efforts and developments in relation to energy piles. General aspects on the performance of energy piles and their impact on the surrounding ground are presented based on previous field, laboratory and numerical investigations as well as existing case studies. Based on the current knowledge, further research opportunities are identified and highlighted.
