Tehnology for absorption of thermal graunenergy with energeticgeotechnical elements

In following graduation thesis I am presenting new possibility for exctraction and usage of renewable energy source, which can be used as a heat source in winter and for cooling in summer.\ud At the very start short overview of well-known technologies for using renewable energy sources in Slovenia. For clearer distingushing I introduce newer terminology, which is based upon Slovenian and international ground temperature profile data. For better understanding of technology for absorption of thermal ground energy with energetic geotechnical elements the basic scheme of system is described. Furthermore supplements to geotechnical elements which make the latter energetic geotechnical elements are described as well as system's appropriate ways of operation. Also short chapter with theoretical background is presented.\ud Moreover four different systems (family house and three non-residential structures) are used for showing the concept of feasibility analysis according to Uredba o enotni metodologiji za pripravo in obravnavo investicijske dokumentacije na področju javnih financ. Each of four system has its own cost model of different options for cost effectiveness analysis. I also included the examples of good practice of buildings that are using technology for absorption of thermal ground energy with energetic geotechnical for heating in winter and cooling during summer.\ud Last topic in this graduation thesis is for presenting numerical simulation made in software Abaqus. Nonlinear dynamic analysis of heat transfer from soil to energy pile was performed for hypothetic case of heating and cooling family house with thermal ground energy
