Abstract In modern high-rise buildings, elevators operate almost continuously and contribute significantly to total electrical energy consumption. A considerable portion of this energy is wasted during braking or deceleration, where the kinetic energy of the moving elevator is converted into heat through mechanical or resistive braking systems. This not only leads to energy loss but also increases thermal stress on elevator components. To address this issue, the present project proposes an energy recovery system using regenerative braking integrated with a battery energy storage system (BESS). In the proposed setup, a DC motor is employed to act both as a motor and a generator depending on the elevator’s operating condition. When the elevator moves downward with a heavy load or upward with a lighter load, the motor operates in regenerative mode, converting mechanical energy into electrical energy instead of dissipating it as heat. The recovered energy is then stored in rechargeable batteries, which can later be utilized to power elevator operations or auxiliary loads within the building. This process effectively reduces the dependency on the main power supply, enhances overall energy efficiency, and lowers operating costs. Overall, this project demonstrates that a battery-based regenerative braking system can play a significant role in promoting energy-efficient and sustainable building technology. It offers a cost-effective, low-maintenance, and environmentally friendly approach to conserving electrical energy and improving the performance of modern elevator systems.
