Energy Geostructures

Energy geostructures are a tremendous innovation in the field offoundation engineering and are spreading rapidly throughout theworld. They allow the procurement of a renewable and clean sourceof energy which can be used for heating and cooling buildings. Thistechnology couples the structural role of geostructures with theenergy supply, using the principle of shallow geothermal energy.This book provides a sound basis in the challenging area of energygeostructures.The objective of this book is to supply the reader with anexhaustive overview on the most up-to-date and available knowledgeof these structures. It details the procedures that are currentlybeing applied in the regions where geostructures are beingimplemented. The book is divided into three parts, each of which isdivided into chapters, and is written by the brightest engineersand researchers in the field. After an introduction to thetechnology as well as to the main effects induced by temperaturevariation on the geostructures, Part 1 is devoted to the physicalmodeling of energy geostructures, including in situ investigations,centrifuge testing and small-scale experiments. The second partincludes numerical simulation results of energy piles, tunnels andbridge foundations, while also considering the implementation ofsuch structures in different climatic areas. The final partconcerns practical engineering aspects, from the delivery of energygeostructures through the development of design tools for theirgeotechnical dimensioning. The book concludes with a real casestudy.ContentsPart 1. Physical Modeling of Energy Piles at DifferentScales1.
