| dc.description.abstract | Currently the issues of sustainable energy demands become critical due to the rapid growth of population and economy. The construction boom in the country has caused the rising of tall buildings for luxury hotels, shopping malls, apartment blocks, etc., particularly in Addis Ababa. The commercial and residential sectors already consume about 60% of the total generated electricity of the country. These trends have undoubtedly influenced the growth of energy demands of the country. Practical researches are indicating that energy demand problems can be mitigated to some extent by using energy pile foundations. Energy foundations are geostructures with a dual purpose: provides structural stability and enable the supported buildings to have a heating and cooling system through exchange of heat with the ground. To this end, the opportunities of meeting some of the country‟s energy demand by introducing energy pile foundation in commercial and residential buildings of Ethiopia were investigated by taking the new United Bank Headquarter Building as a case study. In order to evaluate the performance of energy pile under thermo-mechanical loading condition and the expected amount of energy yield, a preliminary design, simulation and economic analysis were conducted for the existing foundation building using Matlab Programming and Abaqus software. The results of the study revealed that during thermo-mechanical loading, the total axial stress in the pile shows significant increases due to thermal loading that causes axial expansion in the energy pile. In addition, the relative movement of the pile with respect to the surrounding soil mobilizes downward shaft resistance at the upper part and upward shaft resistance at NP. On the other hand, regarding the expected amount of energy extracted, the results of the preliminary study indicated that a significant amount of energy, 719,283.60kWh/year, can be generated. This amount could covers 93.62% of the estimated heating and cooling energy demand of the building. In addition, based on the current electricity tariff of Ethiopia, up to 38,122.03 USD can be saved annually with such energy geo-structure system. From this preliminary study outcomes, it can be concluded that energy pile foundation shall be used an alternative means of energy source by taking the essential design consideration of the additional axial stress due thermal loading. | en_US |
