Geothermal energy systems for major projects – design and construction /

Abstract

The application of geothermal energy has increased in the last couple of years in order to provide the heating or cooling demands of major projects. Open systems using groundwater directly can be used for geothermal energy extraction as well as closed systems with absorber pipes installed in underground structures. An accurate design, which considers the requirements of the energy consumer in particular but also the subsoiland groundwater conditions, the foundation concept and the building structure, as well as project-specific technical, legal and economic conditions, is required for economically efficient application. Diligent supervision is necessary during the construction stage to avoid any damage to absorber pipes, which could result in loss of performance.
