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:
Categorie of use | 1 | 2 | 3 | 4 | 5 |
---|---|---|---|---|---|
Intensity and rate of use | very slight very rarely |
slight rarely |
middle occasionally |
intense frequently |
very intense very frequently |
Average traveltime in hours per day | 0,2 (≤ 0,3) |
0,5 (> 0,3-1) |
1,5 (> 1-2) |
3 (> 2-4,5) |
6 (> 4,5) |
Average downtime in hours per day | 23,8 | 23,5 | 22,5 | 21 | 18 |

Above the input mask is the following toolbar located:
With the toolbar most important commands in menus can be activated.
All changes will take effect when browsing through the registers. On the last active page will be the Energy Efficiency job saved with the button .
By selecting this button, a new energy efficiency contract is initialized and reset all values.
Note: All accomplished changes and calculations will be lost, if the job was not previously saved.
By selecting this button, the dialog is called to open an energy efficiency contract. The following screen appears:
In the upper part of the image can be set different filter characteristics, to search for orders.
After you set the desired filter, please click on that button , to update the list in the lower part of the image.
In the lower part of the image will appear all saved orders.
You can select your one from the list or searching for it with the filter in the upper part of the image.
If you move your mouse over the order number, a tool tip appears with a brief information about this job.
In the Options column, the following icons are visible:
If an order is processed, it is automatically disabled for all others and is only released when it is saved or a new order is entered. If you move your mouse over the “locked-mark” appears, by whom the order is blocked.
As long as the contract has not been released by the author, this can not be edited for security reasons.
Orders can also be locked manually by a simple click on the padlock icon in the options column.
By selecting this button, the dialog is called to store an energy efficiency contract. Detecting a new energy efficiency contract following screen appears.
Please click on the following symbol in the toolbar. By selecting this button, the order data is retrieved:
Please fill out that mask and afterwards click on .
All fields marked with * are required fields.
The “agent” appears automatically based on your application.
Note: On this way only the current job data will be stored, not the job itself!
To save the job please click on in the toolbar.
When saving an already opened energy efficiency-order following screen appears:
By selecting this button, the dialog is called to print a job:
You can choose from several languages.
At first appears the language with which you have registered yourself at the Building Portal.
In addition, use category can be selected. Also, several categories can be selected with the Shift key at the same time.
Click on the button at the top, right. It automatically creates and PDF file, which you can print after that process.
By selecting that button the orders from the module “calculations” can be imported. The following window will open itself:
In the upper part of the image different filter characteristics can be set to look for computational jobs.
After setting the desired filter, click on the button , to update the list in the lower portion of the image.
In the lower part of the image all the stored calculation orders appear.
You can select yours from this list, or search through the filter in the upper part of the image.
If you move your mouse over the order number, a tool tip appears with a brief information about this job.
The following input mask will open itself:
All entries are optional. That means that it is not necessary to fill out every field.
Select from the drop-down list, select the drive system from.
With Clicking in the tabs of the execution mask is automatically saved.
On the last active page, please click:
By selecting the button “Apply” , the dialog will be closed, the entered values are transferred into the order.
Then click on the “Components” to enter the performance data:
Next is the input of the operating and lift elements:
To enter the performance of the lighting, click the “Lighting” tab
After entering all values, click on the tab item “Evaluation“
You will see a complete overview of all consumption, which has calculated the module. At the end of the list calculated energy efficiency appears depending on use Class:
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.

From the following table you can see the values you according to how much energy efficiency class:
