Calculation period

Calculation period

The 'Calculation period' defines the service life of the building. All the impacts are calculated over this period. 
Not all calculation tools have this question form available. For some tools the calculation period is defined by the certification scheme requirements and is not editable by the user.
Press 'Input data' and open 'Calculation period'. Enter the calculation period (service life of the building) as required by the client or by regulation. If no required service life is defined, you can use the service life intended by the designer.
