Abstract Summary
Energy geostructures, represent a local source of renewable heating and cooling. Therefore, they represent highly compelling energy systems to decarbonise the building sector. When dealing with energy geostructures in urban environments, additional challenges arise due to the typical presence of waste heat emissions in the underground, which change the extraction/injection potentials of geothermal heat exchangers. This study concisely investigated the thermal performance of energy barrettes using field experiments and 3-D finite element simulations. This work particularly explores the performance of several energy barrettes included in a complex foundation located in an extremely dense urban area underneath the Testimonio II.
