dear Arianna
I strongly believe that any changes has to be made using the esp-r interface, this is the only way to assure the consistency of the model, changes made directly on the model files
are very dangerous, for example changing a local construction database doesn't work if the model is not updated to expand the changes to the construction files .
I extensively use esp-r for optimization and I always use the text interface using shell scripts very similar to the perl proposed by Gian Luca, this avoids forgetting some important
steps, for example change an obstructions without computing shading database with ish. Fortunately nearly all aspects of the model can be modified using the text interface.
The drawback of the approach is that the sequence must be carefully checked, a misalignment in some position of the script can lead to unpredictable results.
