Hitachi contributes to energy saving by applying various functions such as eco-mode operation and LED lighting to its products.
With the progress of worldwide urbanization, population is concentrated in urban areas, and high and large buildings are increasing. The world's population is expected to exceed 9.7 billion by 2050 and 68 percent of it will live in urban areas. Under such situations, it's an important issue to reduce the energy usage of elevators and escalators that are indispensable in an urban life.
Hitachi is globally promoting the supply of elevators and escalators based on the core concept of supplying systems that proactively anticipate unconscious human behavior. In addition, its products have energy-saving performance as a basic specification.
Energy-saving performance is increased and long-life ceiling lighting is achieved.
Power consumption is reduced by about 5%*2 by increasing the efficiency of the electronic devices and the machine brake.
Regenerative power generated according to the operating status of the elevator is effectively used for lighting and air conditioners in the building. The power consumption of the elevator is reduced by about 30% maximum. *3
By applying LED lighting and the automatic light-off system when carrying no passengers to the balustrade lighting, power consumption is reduced by about 73%.*4
The weight of passengers riding on the escalator is detected based on the inverter load information. Power usage is reduced about 821 kWh/year by decreasing the escalator's speed when few passengers are being carried.*5
The speed of the escalator is reduced when a sensor detects no passenger for a certain time. Power usage is reduced by about 1,970 kWh/year.*5
The speed of the escalator is reduced when a sensor detects no passenger for a certain time. Power usage of about 3,612 kWh/year is reduced.*6
