“…Eskalator yang biasa digunakan di pusat belanja selalu dalam keaadan aktif meskipun tanpa ada penumpang, itu merupakan kerugian yang besar, karna membiarkan eskalator berjalan normaltanpa adanya penumpang [8]. Oleh karena itu, pembahasan tentang penghematan eskalator dalam pembahasan ini menggunakan sistem kontrol dengan sistem kombinasi, khususnya dengan cara aktif-nonaktif dan memperlambat laju motor [9], sistem ini melibatkan inverter sebagai pengatur serta perubah frekuensi tegangan, sedangkan PLC (Programmable Logic Control) untuk mengatur kendali dan merubah kendali pada sistem eskalator, sehingga dengan menggunakan sistem ini bisa mendapatkan penghematan energi lstrik dan biaya, karena hanya mengkonsumsi energi di saat eskalator dijalankan [10].…”

Penelitian ini untuk menganalisa unit eskalator yang menggunakan inverter yang menimbulkan efisiensi karna adanya pengaturan frekuensi yang di atur oleh inveter terhadap kecepatan putaran pada motor listrik. Hasil penelitian menunjukan yakni Eskalator yang di gunakan pada mall atau pusat perbelanjaan menggunkan merk Sigma, untuk penggunaan eskalator yang menggunakan inverter dapat penghematan konsumsi energi listrik, Untuk penggunaan 1 tahun pada 1 eskalator yang tanpa inverter menghabiskan konsumsi energi listrik sebesar 22.484 kWh sedangkan pada eskalator yang menggunakan inverter menghabiskan konsumsi energi listrik sebesar 15.873,9 kWh sehingga penghematan yang di dapat oleh eskalator dengan menggunakan inverter sebesar 6.610,2 kwh dengan biaya Rp 8.411.085 (29,4%). This study is to investigate the escalator unit that utilizes an inverter which makes productivity in view of the recurrence setting set by the inverter to the rotational speed of the electric engine. The outcomes show that the elevator utilized in shopping centers or retail plazas utilizes the Sigma brand, for the utilization of a lift that utilizes an inverter it can save power utilization, For 1 year use on 1 elevator without an inverter consumes 22,484 kWh of electrical energy while on an elevator that doesn't utilize an inverter. utilizing an inverter consumes 15,873.9 kWh of electrical energy so the reserve funds got by the lift utilizing an inverter is 6,610.2 kWh at an expense of Rp 8,411,085 (29.4%).

“…excluding holidays or idle time) of operating and energy performance parameters are determined recalling the usage patterns and can be taken as repeatable in other weeks with the allowed uncertainty limits. Recurring passenger traffic conditions for lifts and escalators have been described by (Tukia et al 2016a, b;Uimonen et al 2017); -The energy efficiency rating of a lift installation is not constant, it varies with the changes in energy uptake during the ride, in the standby mode and in relation to operating parameters, such as for example the transported mass or the distance covered, travel direction, speed, acceleration and deceleration; -A parameter is introduced expressing the usage factor or operational equipment effectiveness for the lift; -To determine the energy efficiency rating of a lift installation, it is required that the running and standby energy efficiency and operational equipment effectiveness factor variations are plotted in the function of time; -Thus, obtained time dependencies of the energy efficiency ratings yield the average energy efficiency which can be treated as the final value in the classification procedure.…”

The study outlines a new approach to lift energy efficiency classification based on a heuristic estimator using the energy performance parameters of a lift installation registered over its weekly duty cycle. Due to the fact that evaluations of the energy performance by commonly applied methods involve a number of variables and complex nonlinear dependencies, the expert model is developed using the fuzzy logic approach. The underlying objectives are defined alongside the energy performance and operating parameters of a lift installation during the ride and in the standby mode. The estimator is based on the operational equipment effectiveness for each mode of lift operation and membership functions (model input and output) are defined. The method was verified by measurements taken on a real object. This study summarises the measurement results and lift energy classification data obtained by the new method, the final results are presented in figures illustrating the energy efficiency variations in the running mode and as the average energy efficiency ratings on each day and over the whole week.

Elevator systems serve as the primary mode of transportation in tall buildings which consumes approximately 5–15% of a building's total energy demand. This research explores the potential for energy savings in elevator systems while maintaining passenger comfort through the implementation of green approaches. The research concentrates on a contemporary high-rise office building situated in the central business district of a developing economy. It employs a case study methodology involving traffic simulation to determine optimal elevator specifications for industry-standard service levels. By conducting the simulation, the researchers identified the optimal number of elevators, elevator capacity, speed, and the most suitable elevator management system. Following that, a range of green measures were implemented, including the incorporation of a regenerative system, to effectively reduce the electrical energy consumption of the elevator system. Subsequently, a passenger traffic simulation model was integrated with an energy calculation model to jointly simulate and calculate the elevator system's overall energy consumption and regeneration. The elevator energy requirements were optimized, while maintaining user-friendliness and requirements related to guidelines given in the standards. The results showed that 36% of the energy consumption was reduced by incorporating an energy regenerative option into the elevator system in addition to selecting efficient mechanical components and implementing an efficient elevator traffic management system. This research contributes to the limited body of literature on energy optimization in elevators and emphasizes the importance of balancing energy efficiency with service quality. These findings provide guidance for establishing benchmarks in reducing energy consumption, in relation to elevator systems.
