Abstract
Z diplomskim delom prikazujem novo možnost pridobivanja in izkoriščanja obnovljivega vira energije za potrebe ogrevanja in hlajenja objektov. Na začetku prikažem kratek pregled znanih tehnologij za uporabo obnovljivih virov energije, ki so že na našem tržišču. Za jasnejše razlikovanje uvedem novejšo terminologijo, ki se opira na podatke temperaturnega profila tal slovenskih in tujih dognanj. Za razumevanje delovanja tehnologije absorpcije toplotne energije tal z energetskimi geotehničnimi elementi navedem glavne elemente energetskega sistema, dodatke geotehničnim elementom, da postanejo energetski geotehnični elementi, načine uporabe in primerno delovanje tehnologije ter krajše teoretično ozadje. V nadaljevanju s štirimi različnimi sistemi stanovanjskega ter infrastrukturnih objektov prikažem konceptualno investicijsko presojo za uporabo toplotne energije tal. Z variantnimi stroškovnimi modeli, skladno z Uredbo o enotni metodologiji za pripravo in obravnavo investicijske dokumentacije na področju javnih financ, naredim analizo stroškovne učinkovitosti uporabe tehnologije absorpcije toplotne energije tal z energetskimi geotehničnimi elementi. V diplomsko nalogo sem vključil tudi dva primera dobre prakse uporabe toplotne energije tal za ogrevanje in hlajenje objekta. Na koncu diplomske naloge predstavim še numerično simulacijo v računalniškem programu Abaqus, s katerim sem napravil nelinearno dinamično analizo prevajanja gostote toplotnega toka iz zemljine na energetske pilote. Slednji zagotavljajo možnost pridobivanja in izkoriščanja toplotne energije tal za hipotetični primer ogrevanja in hlajenja stanovanjske hiše.

Title:Technology for absorption of thermal ground energy with energetic geotechnical elements
Abstract:
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. 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. 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. 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.

Keywords:graduation thesis, cost effectivness analysis, energetic geotechnical elements, energy foundations, feasibility analysis, numerical simulation of heat transfer, renewable energy sources, technology for absorption of thermal ground energy (with energetic geotechnical elements), thermal ground energy, sustainable development, cost model of different options
