Verify the Settings for the Application Calculation Regulation

Verify the Settings for the Application Calculation Regulation

The best way to check whether the CadnaA configuration is in line with specific rules is to apply the corresponding template and check whether there are any parameter that should have another configuration.

In the following example we will check the configuration of the CNOSSOS method:

1) After you have configured the CadnaA project, access Calculation/Settings:



2) Click on the green icon of the "Template" parameter and select the value2021/1226 Euof the parameter"Template" (more updated version of the CNOSSSOS method):



3) The lower window should show deviations from the configuration of the current CadnaA project from the CNOSSOS method rules.



(4)Subsequently, it will be necessary to verify the particularities of each project according to each region. For example, both Lden and Ln are calculated in Spain. In this case, it is necessary to configure CadnaA to calculate the 4 parameters and not just Lden and Ln as stipulated in the European Directive.
