Orona G1000 Elevators: High Electricity Consumption, Idle Run Costs, Optimization Ideas

We have 3 Orona S.Coop elevators in the block. type of drive: G1000 by Grupo Orona, power: 7.4kW 3x400V / 50Hz, 1000kg, 13 people. Looking for reasons for high power consumption, we noticed that elevators consume > 50% of electricity costs. shared. Recent measurements have shown that the idle run (standstill) of these elevators is a total of about 1 kW / 1 lift - including the motor, lighting, ventilation - i.e. 8670 kWh / year, and therefore > 5000 PLN / year only the idle run of 1 lift! We noticed that when the elevator is empty, it consumes about 3x more energy when going down than when it is stationary, and when it goes up with 1 person, it consumes electricity similarly to when running at idle - what could be the reason for this? counterweight?

Hence the question of how to optimize the energy consumption of the elevator? Does it have to work all the time at a standstill, even at night? Are motion sensors for lighting acceptable, etc?

Addendum1. I am aware of technical supervision, which is why all ideas would be outsourced to an appropriate company with permissions...

Power is measured in kW and energy in kWh.
What is the power of the lighting in the cabin and is the light in the elevator shaft turned off?

Of course, power in kW, and energy in kWh ...
200W only fluorescent lamps in 1 elevator and they are lit 24 hours a day. Riding up is probably with a large counterweight, because it does not take more energy, while down it already takes ...
Is the counterweight too big? How is it defined? For full load probably (13 people), and we usually have 2 people ... Thanks for the link.

On their website it is possible to buy saving variants, it is interesting whether they are only for new ones, or whether it is possible to modernize them link

Thanks for the link, I called Poznań and I already know that:
- the lift when loaded with 50% (500kg in our case) should load the same way up and down
- the lift at a standstill consumes approx. 200W of electricity
- it is possible to add a Stand-By plate and then greater savings

So where do you get 1kW of consumption at a standstill? ....
Do you have to wear sunglasses or a welding mask on this elevator?

hihihi, I've been fighting with it for half a year, but success is getting closer ... I have to do the elevator shutdown test, because probably other garbage ... And as for the light, in my opinion, there may be 10 fluorescent lamps while driving, but only 1 after time trial for safety ... I already have arguments for modernization. Regards
