Optimization of Energy Consumption of an Office Building in Tehran Region

The continuous growth of urbanization, the emergence of megacities, and the subsequent increase in their population have had various consequences among which the increase in consumption and demand for energy resources can be mentioned. Energy consumption has increased dramatically in the last few decades, which has also caused an increase in the production of greenhouse gases. The importance of energy at the global level is something that has been paid attention to a lot, in Iran also due to the increasing statistics of fuel consumption, optimizing and saving consumption is vital. Therefore, in this research, by using previous studies and computer simulation, we tried to investigate the effect of the factors involved in the energy consumption inside the building. In this regard, a building with office occupancy has been investigated in terms of energy consumption. The considered building has been simulated in Design Builder software and analyzed in terms of energy consumption and other factors in this simulator. In order to optimize energy consumption, intelligent lighting systems, phase-changing materials on external walls, 3-pane windows with high sealing, and natural ventilation have been used. As a result of using these solutions, the optimal building compared to the original building has improved energy consumption from grade C to grade B.
