Premium-efficiency elevators have entered the market, featuring improved controls, hardware, and other systems that use less energy, are more compact, and even generate their own electricity. However, although significant energy savings are possible with premium-efficiency elevator systems, when compared with conventional systems the added costs remain too high to justify installing premium-efficiency systems for energy savings alone. Simple payback periods can range from 20 to more than 200 years. Nevertheless, premium-efficiency elevators offer many non-energy benefits that building owners may find compelling, such as high performance and improved reliability. The energy savings—which can run into the tens of thousands of kilowatt-hours (kWh) per year relative to conventional elevators—may be a bonus to building owners.
