Energy regeneration from gravity”: A sustainabile approach for vertical transportation in high rise buildings

Bio-mimicry is the field of study that compares nature and implementing a process to duplicate in manmade systems. This paper envisages the concept and points that how this can be morphed in to building systems to create a more sustainable built environment. With elevators accounting for up to 15% of the high rise building sector´s use of energy, green innovations can offer large reductions in carbon footprint. The energy required for daily operation of elevators in a high rise building has the biggest impact on energy footprint of our built environment. Therefore energy efficiency shall be an important feature for high rise elevators. The last few years have witnessed a change of course with companies introducing energy efficient technologies for competitive reasons and, at the same time, to help their customers save energy and money. Today, electricity is becoming an increasingly precious commodity and it is therefore essential that most of this energy can be recycled back. An expanding variety of traction elevators is tapping the advantages of regenerative power technology, a practice to recover the power generated by elevators and supplying back to the power source.
