In civil buildings, large part of energy consumption of common service is related to lift apparatus operations. Considering the huge diffusion of roped elevators and their reciprocating operating mode, a critical evaluation of energy streams has been done using an accurate model specially developed. Thus, a retrofit kit has been studied and designed able to store the energy during the generating mode of the electrical machine and to recover it back in motor operation. Finally, a comprehensive evaluation of the saved energy parameterized with the numbers of passengers and lift duty cycle is presented, as well as the kit cost estimation and pay-back time.
