Re: Ask a Scientist

Lifts wait at the main entrance floor because that is the most likely floor for them to be needed; far more people go from the entrance to their "home" floor than between floors.

Generally they are balanced with the lift slightly heavier than the counterweight, so going down uses very little energy, but I've only heard of energy capture being used in some show buildings where energy efficiency is the main feature.

Of course if they have to go back up empty, that will waste energy.

If there are multiple lifts, not all will park at the entrance.
