An increasing population causes more energy demand, resulting in an increased rate of electricity production. Thus, increasing the electricity production rate wastes more fuel resources. These limited resources are depleted if not used properly. Therefore, energy conservation is an essential point that we should be aware of. In addition, weather and geography are significant factors that directly affect the energy consumption rate. Fundamentally, cold regions use more energy for heating, while tropical areas use more energy for air conditioning. Therefore, if the energy used for these fundamental needs can be saved, it will effectively reduce the overall rate of energy use. Consequently, environmental factors that affect energy consumption, such as wind flow direction, building orientation, and pressure, were observed. The observation was done by simulating in a Computational Fluid Dynamics (CFD) program. At the same time, an energy-saving method is also proposed in this paper. The results showed that the proposed method can reduce the energy consumption rate, which is beneficial for the development of energy management systems in the future.
