We are reinforcing our role as a pioneer in modern design and construction. In cooperation with experts from the VSB \u2013 Technical University of Ostrava, we are working on a unique project that enables the extraction of ecological geothermal energy directly from underground structure constructions. The project is being developed with financial support from the EU under the \u201cTechnologies and Applications for Competitiveness\u201d Operational Programme.<\/p>\n\n\n\n
While conventional ground source heat pump (GSHP) systems are already relatively common in the Czech Republic, we are focusing on the innovative approach of so-called energy geostructures. This involves integrating heat pumps directly into the load-bearing elements of structures \u2013 for example, into foundation piles, slabs, retaining walls, or tunnel linings.<\/p>\n\n\n\n
Conventional underground structures, such as tunnels, metro stations, or building foundations, can, thanks to installed exchangers, serve not only their structural function but also act as a source of renewable energy. In winter, we can heat surrounding buildings or platforms, while in summer, residual heat obtained from cooling buildings can be stored in the rock environment for later use.<\/p>\n\n\n\n
Compared to GSHP systems, these systems are more efficient because they utilise the enormous contact area between the structure and the rock mass, which therefore serves as a natural heat reservoir. This technology also helps protect the infrastructure itself, for example, by eliminating the freezing of drainage pipes in tunnels or the formation of ice on platforms or pavements.<\/p>\n\n\n\n
Main Advantages of the Technology:<\/strong><\/strong><\/p>\n\n\n\n We are already applying our findings and experience in real projects. We have prepared studies for Prague Metro Line D (Nov\u00e9 Dvory station) and for the Czech Road and Motorway Directorate, where we are examining the use of energy from motorway and road tunnels for their own operation and for surrounding buildings.<\/p>\n\n\n\n Part of our current research also includes the development of smart sensors based on optical (silica) fibres, which measure temperature in real time within a range from \u201340 to +50 \u00b0C. The device can also monitor the condition of the entire structure and track deformation changes on the scale of micrometres.<\/p>\n\n\n\n Compared to abroad, this technology is still lagging behind in the Czech Republic. Our project aims to break this barrier. We believe that optimising the distribution and use of energy from underground structures is the key to modern \u201cSmart Cities.\u201d<\/p>\n\n\n\n The use of geothermal energy from underground structure constructions is suitable for transport infrastructure projects as well as for heating and cooling within industrial complexes. Such a solution will bring companies not only a more sustainable energy source, but also long-term cost reductions \u2013 because after the initial investment in the exchanger, the energy can be utilised without limitation.<\/p>\n\n\n\n The project is co-financed by the European Union, specifically through OPTAK \u2013 the Operational Programme Technologies and Applications for Competitiveness.<\/p>\n\n\n\n Provider:<\/strong> Ministry of Industry and Trade<\/p>\n\n\n\n Registration Number:<\/strong> CZ.01.01.01\/01\/24_063\/0006929<\/p>\n\n\n\n Recipient:<\/strong> SAGASTA s.r.o.<\/p>\n\n\n\n Project Duration<\/strong>: 1 April 2026 \u2013 30 June 2028<\/p>\n","protected":false},"excerpt":{"rendered":" We are reinforcing our role as a pioneer in modern design and construction.
