With the INTERFACE module it is possible to specify changes in several energyPRO projects without having to do it in each of the individual files as the changes are made in a XML-file.

By using the INTERFACE module investigation of e.g. the impact of installation of a solar collector in different configurations or changes in existing time series, demands, prices, taxes etc. can simply be made. 

As the user only has to make changes in a single project file and perform a new set of calculations using the INTERFACE module this module is very convenient and time-saving when having a large number of energyPRO project files or wanting to simulatate numerous scenarios.
