Energy Efficient Civil Engineering Structures – EECES

The current discussion related to energy demandness, sometimes generally referred to by the abbreviation Green Deal, basically comes from two directions – reducing energy in absolute values, or when it is necessary to use renewable energy sources to a greater extent and thus reduce the consumption of fossil fuels. Construction is generally associated with high energy consumption, which is most often reported in the range of 30–40% of total consumption. However, current attention is mainly focused on buildings under the designation Energy Efficient Buildings - EEB. The contribution is therefore focused on the area of civil engineering structures, which still remains in the background of attention and is devoted to both the reduction of total energy consumption and the possibilities of using renewable energy sources. However, the main difference in possible energy savings compared to buildings can be determined in the different stages of preparation, construction, and structures phase of utilization. In the case of EEB, it is mainly about the reduction of consumption during the phase of the building utilization, in the case of civil engineering structures, it is mainly about the first phases. The basic possibilities of achieving these goals are therefore the main focus of the contribution, when the possibilities are primarily directed to the geotechnical constructions of transport structures.
