The PORT Technology meets today’s environmental challenges by managing the trips made by your elevators so that passengers are transported in the most efficient manner possible. Further, the equipment has been designed to use a reduced level of power consistent with the many features it provides.
Traditionally during off-peak times, all the elevators in the group are still in operation. This means that elevators will do many trips to transport only a few passengers, leading to low efficiency. Usage of energy is particularly high in lightly loaded elevator cars because of the large load offset between cab and counterweight.
The unique PORT Technology Energy Control Option (ECO) allows to save energy while keeping passenger waiting times at an acceptable level. The level of acceptable average waiting time is adjustable for each building. Higher acceptable waiting times allow for higher energy savings. The PORT Technology ECO monitors the traffic conditions continuously and keeps average waiting times below or at the specified level, while saving the maximum of energy possible. In off-peak hours, the passengers may wait a bit longer than without ECO, being allocated to less elevators, but thanks to a smaller number of elevator trips and an improved balance of the elevators cabins they contribute to energy savings. When feasible, the elevators on standby are set to an energy saving sleep mode. The use of this complementary approach for heavy and light traffic can provide significant energy savings throughout the day.
The PORT Technology can offer operators of other building systems occupancy data which can help enable the more efficient use of their equipment. This data can be either historical or real-time and can enable more intelligent utilization of other building equipment to further reduce energy use.
Schindler is committed to advancing The PORT Technology to minimize customers’ total building energy consumption while making sure the energy that is used provides the optimum environment for their tenants.
