14.1.2 Project data
The Energy Performance Certificate
The results of the energy efficiency calculation are documented in the Energy Performance Certifi-
cate:
• The Energy Performance Certificate contains detailed information on the required energy of the
application, the different drive components, and of the drive system as a whole.
• The energy costs are displayed transparently and clearly.
• In addition, the recoverable energy is shown, which can be exchanged via the DC-bus or fed back
into the supply system by means of a regenerative module.
• The CO
2
emission according to the CO
2
equivalent 550 g/kWh (source VDI) for the energy re-
quirement and the recoverable energy is shown for the drive system as a whole.
• All results for the machine cycle (cycle time of the motion profile) and for the selected period un-
der consideration (e. g. 5 years) are summed for the drive system as a whole.
• The energy requirement and the costs for the whole period under consideration are determined
for the drive components and the application.
Designation Description
Selection of the projects to be compared to each other.
• Display of all projects that are currently opened in the DSD.
• The project from which you have opened the Lenze BlueGreen Solutions, is a ref-
erence project. It ranks first and cannot be deselected.
• Remove the checkmark if you do not want to include the projects into the com-
parison.
• Each project is assigned to a colour. This makes it easy for you to detect it in the
cost diagram and while comparing costs.
No. Project number that are automatically assigned to the project.
• DSD assigns the project number according to the sequence of the opened
projects.
Project Name of the project.
• Indicates the file name of the DSD project.
