Low-power lifts

The elevators

are one of the present electricity consumption in buildings. Its consumption largely depends on the following factors :

• Main use of building: residential, hospital, administrative ... Features
• of building height, number of units in use ... Type
• elevator technology.

The use of the building affects according to frequency of use of lifts by users. For example, in a hospital where there occur inpatients increased traffic of users in buildings with other uses.

is important to make an estimate of the frequency of use of the elevators in the building at the time of making a correct estimate of their energy .

On the other hand the edifcio characteristics also significantly affect their consumption and high-rise buildings will be more significant consumption as a smaller number of users used the stairs and the consumption path will be higher.

In terms of technology distinguish the following types Elevator: Hydraulic lifts

• .
• two-speed electric elevators. Electric Lifts
• variable frequency and voltage. Electric Lifts
• variable frequency and voltage without engranajescon permanent magnet motor and heavy-duty flat ribbons, ie art lifts and high energy efficiency.

This latter type of lifts are an important technological change in regard to low power consumption and energy efficiency:

• consume between 25% and 40% less than conventional electric lifts.
• Consume 60% less than hydraulic lifts.
• are very quiet.

The following table takes compratir consumption a lift last generation and an electric elevator conventional two speeds depending on the capacity of the same:

deserve consideration all these factors when making a correct choice of lift to be used in a building.
