Special Issue Information

Dear Colleagues,

Due to the effects of the progressing global climate change even on a regional and local scale and extensive changes in land use, towards constant increasing land consumption, increased flooding events are expected in the short and also long term and will cause substantial economic damage. Areas will also be affected that have been spared from these events until now.

An accumulation of such devastating flood events is expectable in the next years as on the one hand land use pressures have intensified and will be intensifying in the future as well. On the other hand, climatic conditions are supposed to be changing so that intense rain events will increase in terms of intensity, frequency, and variability. Therefore, sustainable and effective solutions have to be developed. Decentralized and local-based flood protection is one of the sustainable approaches and key technologies for reducing surface runoff and retaining water locally. Due to increasing land use pressure decentralized flood protection areas should have further sustainable ways of utilization. Shallow geothermal use for heating and cooling is one sustainable extension for decentralized flood protecting areas due to the well-known local pedological and vegetation conditions and close distance to infrastructure. The combination of these two technologies will help to develop comprehensive decentralized sustainable approaches dealing with the upcoming effects of progressing global climate change.

Horizontal shallow geothermal applications are easy to install, and their installation process is less liable to legislation than other geothermal systems. Due to a lack of planning guidance, the opportunity to implement such systems is often overlooked, although geothermal installations are urgently needed as a sustainable energy source. To give a foundation for including very shallow geothermal systems in local heat supply planning, potential maps are crucial. To enable their utilization in energy use plans or similar elaborations for municipalities, location-specific and system-specific heat extractions are required. Since applicable standards are not available, it is nearly impossible to provide aggregate propositions, which are essential for potential maps. In this study, a concept was evolved for deriving very shallow geothermal potential maps with location-specific and system-specific heat extraction values. As a basis, VDI 4640 Part 2 information regarding heat extraction and respective climate zone references was utilized. Furthermore, climate information and a soil map were needed to apply the concept to the study area. The application of the concept in an Austrian study area resulted in appropriate potential maps. Moreover, this concept is similarly applicable in other areas of interest. Full article
