Currently the issues of sustainable energy demands become critical due to the rapid growth ofrnpopulation and economy. The construction boom in the country has caused the rising of tallrnbuildings for luxury hotels, shopping malls, apartment blocks, etc., particularly in AddisrnAbaba. The commercial and residential sectors already consume about 60% of the totalrngenerated electricity of the country. These trends have undoubtedly influenced the growth ofrnenergy demands of the country. Practical researches are indicating that energy demandrnproblems can be mitigated to some extent by using energy pile foundations. Energyrnfoundations are geostructures with a dual purpose: provides structural stability and enable thernsupported buildings to have a heating and cooling system through exchange of heat with thernground. To this end, the opportunities of meeting some of the countryâ€Ÿs energy demand byrnintroducing energy pile foundation in commercial and residential buildings of Ethiopia wererninvestigated by taking the new United Bank Headquarter Building as a case study. In order tornevaluate the performance of energy pile under thermo-mechanical loading condition and thernexpected amount of energy yield, a preliminary design, simulation and economic analysis werernconducted for the existing foundation building using Matlab Programming and Abaqusrnsoftware. The results of the study revealed that during thermo-mechanical loading, the totalrnaxial stress in the pile shows significant increases due to thermal loading that causes axialrnexpansion in the energy pile. In addition, the relative movement of the pile with respect to thernsurrounding soil mobilizes downward shaft resistance at the upper part and upward shaftrnresistance at NP. On the other hand, regarding the expected amount of energy extracted, thernresults of the preliminary study indicated that a significant amount of energy,rn719,283.60kWh/year, can be generated. This amount could covers 93.62% of the estimatedrnheating and cooling energy demand of the building. In addition, based on the current electricityrntariff of Ethiopia, up to 38,122.03 USD can be saved annually with such energy geo-structurernsystem. From this preliminary study outcomes, it can be concluded that energy pile foundationrnshall be used an alternative means of energy source by taking the essential design considerationrnof the additional axial stress due thermal loading.
