The use of office equipment for various office tasks is increasing day by day due to the advancement of technology. Purchase of low-consumption equipment and the proper operation causes to reduce the energy consumption of the electrical system and the cost of electricity bill of the office building. For this reason, in this article, the optimal selection of conventional office equipment is investigated to improve the technical and economic indices. The consumption rate, speed, and installation and operation costs of equipment are samples of technical and economic indices of devices that are considered using the life cycle cost method for selecting the optimal technology of office equipment. Finally, the optimal technology of devices is selected using the numerical simulation in MATLAB software. The three operational periods, 1, 10, and 20 years starting from 1400, are considered the research's operational period. Moreover, the methods for more improvement of technical and economic indices of the office building are also proposed and evaluated after selecting the best technology of equipment. Results show a considerable improvement in the efficiency of the electrical system of the office building. In different devices, electricity consumption and costs are reduced by about 20-70 percent by selecting the proper technology using the proposed method.
