Geothermally activated mixed-in-place walls as permanent components of a sustainable energy system: case history

Abstract

Geothermal activation of geotechnical construction elements facilitates the storage of renewable energy. During summer, solar energy is captured, stored underground, and subsequently utilized for winter building heating. In addition, the sustainable approach by using the mixed-in-place (MIP) method reduces carbon emissions and transportation burdens already during construction phase. The method‘s granular interlocking ensures efficient heat transfer to geothermal probes. Integrating geothermal activation right from the planning phase into building technology enables seamless incorporation. The synergy of geothermal activation and the MIP technique not only cultivates eco-friendly building concepts but also mitigates environmental impact across the entirety of a building‘s lifecycle. Geothermal activation and MIP can be applied to large-scale infrastructure projects, enhancing sustainability.
