Are You Losing Energy? Your outdated elevators may be costing you more than you think-not only in utility bills, but also in the perceived value of your building. By Roy Andersch elevators W hen the time comes for management and ownership to consider modernizing their building systems, elevators and escalators may not always be the first to jump to mind. However, considering their true impact on energy use, tenant satisfaction and the ways they interact with a building's visitors every day, these mobility solutions are fast becoming prime upgrade candidates for the savviest building management professionals. Elevator systems can make up 3 to 7 percent of a building's total energy consumption each year, and companies are constantly introducing new technologies that significantly improve performance, reliability and energy efficiency to reduce their impact on the bottom line. For example, new elevator modernization packages offer building owners the latest features, allowing outdated, inefficient elevator components to be easily retrofitted to existing equipment, often with minimal downtime. Typically, one of the largest sources of energy waste in elevators are the drive systems. Older drives such as When moving crowds means individual attention Every day, more than 1 billion people around the world trust Schindler products to move them throughout their day. That's the equivalent of the entire world population every week. And, as the largest supplier of escalators and the second largest manufacturer of elevators in the world, it's a trust we intend to keep. Whether we're installing, servicing or modernizing an elevator, escalator or moving walk, we promise to deliver reliable mobility.

They can also contribute to hidden energy costs in a building because they generate a lot of heat, which can require additional energy from building systems like HVAC to cool the equipment. One of the best ways to combat this is to install highly efficient regenerative drives. Today's technologies, such as regenerative drives, are far more efficient than their predecessors; they can regenerate energy back into a building's grid at a power factor of 0.99, providing up to a 40 percent energy savings over older systems. Additionally, converting an older geared machine to the latest gearless machines not only offers significantly better ride quality and performance, but also can result in another 15 percent or so in efficiency gains. These conversions are made easier with the introduction of products such as modular gearless machines specifically designed to be used in existing machine rooms. Some new machine features include a compact design and minimum dimensions, allowing the parts to fit through standard machine room doors and be assembled in the machine room for maximum ease of installation. Today's technologies, such as regenerative drives, are far more efficient than their predecessors; they can regenerate energy back into a building's grid at a power factor of 0.99, providing up to a 40 percent energy savings over older systems. When you couple regenerative drives with gearless machines and destination dispatch, you can experience tremendous benefits in energy efficiency of up to 60 percent over older elevator systems. Companies have bundled many of these upgrades into easy-to-use modernization packages for low-, mid- and high-rise applications to help improve a building's overall energy efficiency and value, and to contribute to better leasing conditions and higher occupancy rates. Finally, the latest destination dispatch systems safely transport more people with less elevator stops, maximizing the efficiency of the entire system and spending as little time and energy as possible getting www.buildingmanagementhawaii.com http://www.us.schindler.com http://www.buildingmanagementhawaii.com
