Energy recovery system for elevators in office building. Case study.

The energy recovery system for elevators ERS is installed in a lift, with high traffic, in an office building in Zaragoza (Spain).

The elevator specs are:

• Existing elevator: KONE.
• Distance/Height: 9 floors.
• Maximum load: 630 kg. / 1388 lbs.
• Speed: 1m/s.
• VVVF Drive: Kone KDL 16

The installation of the energy recovery system ERS 2G from epic power is quick and easy (just two cables), and can be done in new or existing elevators.

In the graph, you can see the overlapping consumptions during each trip before (brown) and after (blue) installing the system.

Benefits of installing the energy recovery system ERS 2G from epic power.

If we look at the graph, without the energy recovery system ERS 2G from epic power, there are consumptions of more than 5000W at the start of each trip.

After an easy and quick 20-minute installation, these strong consumptions that occur during the starts are highly reduced, around 4000W.

The real impact of using this system lies in the storage of energy generated during the “generation trips” (descent of a full cabin or the ascent of an empty cabin), and its subsequent reuse to reduce the energy consumption of trips powered by the electrical grid

Energy savings

In this building, the installation of the Energy Recovery System ERS 2G from Epic Power results in a 37% reduction in the energy consumed by the elevator.
