Liftronic Pty Limited is Australia's most reliable elevation supplier. With more than 30 years in the industry, our team shares the latest insights on the world of elevators, escalators and everything else that takes us to new heights.
Although elevators only account for around 5% of a building’s energy use, modernising or upgrading your lifts can give you an immediate return on your energy-efficiency investment.
Simply by replacing outdated hardware (many elevators are running long past their useful lives) and investing in some of the sophisticated software now on the market, building owners can make immediate and substantial energy savings.
When upgrading elevators, building owners should consider whether their lifts are hydraulic or traction. Hydraulic elevators have a piston inside a cylinder, which lifts the cab when an electric motor pumps in oil. This hoisting method uses a lot more energy than a traction system and is more expensive to maintain. Although new valve block technology could greatly improve your hydraulic elevator and give it a new lease on life.
A traction elevator on the other hand, travels up and down on a steel rope, which has a counterweight on the other end. Because the counterweight is sharing some of the load, by nature traction lifts are more energy-efficient than hydraulic hoists.
So simply by replacing one with the other (most new elevators now use traction lifts), you can reduce your operating costs substantially. Modern traction lifts also use a regenerative drive which captures the downward energy of the cab and transforms it into electrical power, which is then pumped back into the building’s energy grid.
Another advantage of modern traction elevators is they don’t require a machine room, as the motors and other equipment normally housed there have been redesigned to fit into the lift shaft. This creates more usable space, less heat and consumes less energy.
Other hardware improvements you could make include;
One of the biggest improvements to elevators in the last few decades has been to their control systems, with modern elevators now boasting software that is able to implement all kinds of energy saving strategies;
If you can’t justify the expense of data logging software, you could hire a third party to conduct an elevator audit. This is a cost-effective way to evaluate the age of the equipment and discover where energy-efficiency savings could be made.
So how much energy can you actually save with an upgrade? Here’s what you could expect with Liftronic Pty Ltd’sEco-Solutions;
Upgrading ageing elevators is a grudge purchase for any building owner, but something that is going to have to be done at some stage, so benefiting from the energy savings now rather than later would make sense.
If your elevators are not modernised (or at the very least kept maintained to minimum fire, safety and customer satisfaction standards) you could be facing a much larger bill further down the track.
It’s important to remember that these changes don’t have to be implemented simultaneously. To make them as affordable as possible, you can phase them in over time, as and when your maintenance budget allows.
