How can you store summer heat for winter?

The article discusses energy geotechnical constructions, which are structures like foundations, piles, and trenches in contact with the ground equipped with heat exchange systems. These systems allow buildings to store excess heat in the ground during warmer periods and reuse it for heating when needed. The technology, part of shallow geothermal energy solutions, has been developing globally for over two decades and is considered a promising sustainable solution for building heating and cooling. The article explains how these systems work through pipes filled with fluid that absorbs and releases heat, using heat pumps to transfer the energy where needed. It highlights the advantages of integrating such systems during construction, particularly in Slovenia, where deep drilling costs are significant. Experts note that while this technology offers cost savings, it requires careful planning based on soil properties and temperature changes. Research by French professor Sandrine Rosin-Paumier indicates that repeated temperature cycles affect the mechanical properties of fine-grained soils, prompting the development of models to ensure long-term safety.

In Slovenia, researchers and engineers are exploring innovative ways to store summer heat for winter use, by integrating thermal energy systems directly into building foundations. This emerging technology, known as energy geostructures, involves embedding heat exchange systems within geotechnical elements such as piles, foundation slabs, and trenches during construction. These structures leverage the stable temperatures found underground to capture excess heat during warmer months and redistribute it during colder periods, offering a sustainable solution for heating and cooling buildings. The approach falls under shallow geothermal technologies and has been gaining traction globally over the past two decades. The system works by installing pipes within these geotechnical components, through which a fluid circulates in a closed loop. In warm conditions, the fluid absorbs heat, while in cold conditions, it releases stored heat. A heat pump transfers this energy to areas where it is needed. Because ground temperatures remain relatively constant throughout the year compared to air, they provide an efficient medium for thermal exchange. By incorporating these systems during the construction phase, additional deep drilling, which can be costly, is often unnecessary, significantly reducing investment costs. One of the main advantages of energy geostructures is their integration with existing geotechnical infrastructure. If planned early in the design process, these systems can be seamlessly incorporated into the foundation without requiring extra work. According to Dr. Stanislav Lenart from the Slovenian Institute of Civil Engineering (ZAG), this could lead to substantial savings, especially since many projects in Slovenia already rely on pile foundations and protected excavation walls. However, the technology is not universally applicable. Each system must be carefully dimensioned based on soil properties and the potential impact of temperature changes on both the structure and surrounding ground. Heating or cooling the earth can affect soil stability, deformation, and water movement, necessitating thorough analysis before implementation. Research conducted by Prof. Sandrine Rosin-Paumier from France highlights the effects of repeated temperature cycles on fine-grained soils. These cycles can alter moisture distribution and how soil responds to loads. As a result, researchers are developing experimental and numerical models to better predict these processes and ensure the long-term safe operation of energy geostructures. Despite these challenges, the technology has been in use for more than twenty years in several European countries, particularly in commercial buildings, residential complexes, tunnels, and infrastructure projects. Its development has accelerated due to the global push toward low-carbon heating and cooling solutions. Slovenia appears well-positioned to adopt this technology, given its favorable geological conditions and numerous new constructions utilizing pile foundations. For instance, the method could enable the storage of thermal energy in road embankments, which could later be used in winter to prevent road surface freezing. In all these scenarios, systems for shallow geothermal energy could be integrated into the planning stages of projects. The ground beneath our feet is not just a load-bearing base for buildings but also a valuable and cost-effective medium for storing and exchanging heat. By thoughtfully incorporating this potential into building designs, summer overheating of structures and infrastructure can be reduced, and part of the required winter heat can be sourced from the ground where it was stored during the summer.
