I caution readers of this article to take the energy reduction claims by KONE with a grain or two (or more) of salt. Your article is filled with fantastic claims of energy savings. 50% reduction by 2010; 30% reduction over current products; 70% less than hydraulic; 50% less than conventional traction; 40% of the world's energy needs; up to 10% of a buildings energy consumption. It's easy to make these dazzling claims, but exceedlingly difficult to prove.

Yes, these products are more energy efficient than their predacessors. But building owners and operators should not be bamboozled into thinking that more energy efficient elevators are the answer to their energy problems. Most of these claims are exagerated, and the overall energy impact on a building by the elevators is relatively small. These energy savings products typically do not have a realistic payback.

Saving energy is a good thing, no one will argue. But energy efficieny is on everyone's radar these days, and all elevator manufacturers have energy saving technologies. In the not too distant future, these energy saving devices will not be options, but will be the standard equipment provided on all such systems.

Be careful of unsubstantiated and unproovable claims. And put the results in perspective.
