Having these aspects in mind, engineers have come up with inventions such as Machine room less Technology which was initially introduced in the mid-1900s and the fact that miniature versions of the technology have sprung up it has made it much more convenient to run an elevator incorporating a gear less traction design. These elevators look to save up to 50% of energy reduction than earlier inventions. Some also make use of already used energy and recover the same energy used to put it back into the building’s electrical system. Looking at the large scale of things, you’d comfortably save a lot of energy in a month alone. They are generally referred to as regenerative drive system.
There are current technologies that make use of double deck elevators or as we call them, group control systems for buildings with high traffic. It would ideally move traffic to one lift at a time and minimize on the number of stops it would have to make. You’d find one lift only makes stops to even numbered floors or it makes stops on odd numbered floors.
There’s also the use of in-cab sensors that allow elevators to go into idle mode, the same way phones would go to sleep mode when they’re not being used so as to save on energy used. Therefore, when the lights go out, the music stops, video screens are off and the ventilation system slows much of electricity and energy are saved up thus helping cut on costs incurred as well. Lastly we have the use of destination dispatch software that take elevator stops in batches and then makes all the necessary stops in one trip rather than having every single person going to one floor then wait for the next trip before they get to where they are going.
