The comparison of the energy performance of hotel buildings using promethee decision-making method

Abstract

Annual energy performance of the atrium type hotel buildings in Belgrade, Serbia, climate conditions are analysed in this paper. The objective is to examine the impact of the atrium on the hotel building's energy needs for space heating and cooling, thus establishing the best design among four proposed alternatives of the hotels with atrium. The energy performance results are obtained using EnergyPlus simulation engine software, taking into account Belgrade climate data and thermal comfort parameters. The selected results are compared and the hotels are ranked according to certain criteria. Decision-making process that resulted in the ranking of the proposed alternatives is conducted using Promethee method and Borda model. The methodological approach in this research includes the creation of a hypothetical model of an atrium type hotel building, numerical simulation of energy performances of four design alternatives of the hotel building with an atrium, comparative analysis of the obtained results and ranking of the proposed alternatives from the building's energy performance perspective. The main task of the analysis is to examine the influence of the atrium, with both its shape and position, on the energy performance of the hotel building. Based on the results of the research, the most energy efficient model of the hotel building with atrium can be determined for Belgrade climate area.
