I dont think that ecodesigner calculate thermal bridges.
It alow you to modify some R values and you can put newer elements and values .
You can precalculate a medium value of a wall type therm. resist. with thermal bridge influence included .
So is not a correct and utile thermal analisys addon . Shameful for a BIM , only a child toy to pretend you have " calculated " something . Even with dedicated software is difficult to have a proffessional result of thermal bridges influence . For this reason was developed catalogues of thermal bridges dependant of country specific regulations . See european standard EN ISO 13370 . It is not so simple. Good luck .
