The calculation of the energy efficiency in accordance with Directive VDI 4707 sheet 1.
The results can support resource-efficient management and form a quality feature of elevators and your company as well as lead to a sustainable management. At the same time can be made a sustained-action contribution for a future-proof environment, namely lower environmental pollution, trough the energy-efficient design of the elevators.
The system is used for the identification and assessment of new passenger and freight elevators and for the subsequent determination of the energy efficiency of existing lifts.
Energy efficiency can also be used to determine the anticipated energy consumption:

  • Demand values
    (calculated expectation values​​, which are based on certain specifications)

    • Energy efficiency for stationary
    • Energy efficiency for driving
  • Consumption values
    (effective, measured consumption)

After following categories of use, the energy efficiency values ​​are calculated:

Energy Efficiency Computation Results Part 2

To convert the standstills and travel demand in an energy efficiency class, the elevator will – depending on frequency of use – divided into one of five categories of use. The average travel time per day determines the Category of use: The more often the lift is used, the higher is the utilization category.

Based on the calculation suggests the portal before a Category of use. This proposal is grayed out. About the use of categories, the calculation of the utility category is displayed.
