This paper discusses the dynamic system modeling in an elastically supported rigid cylinder for electrodynamic vibration energy harvesting. In this paper, the fluid flow used is very different from the research that has been done, the fluid that will be used is air. A lot of airflows is generated in tall buildings, especially in the ducting flow. By utilizing airflow, home energy is developed. The harnessed energy used is electrodynamic vibration energy harvesting which arises from the tension of the wire and beam that vibrates due to the turbulence that is formed which produces an external force, causing the cylinder to insulate. The simulation results show that the airflow velocity and diameter greatly affect the amount of power generated. At an airflow rate of 8 m/s, the power generated is 2 × 10−17 watts. At a diameter of 80 m, the power generated is less stable. The phenomenon that occurs due to the placement of electrodynamic vibration energy harvesting, placement at point B has a faster power than the placement at point A.
