Keep in mind that heat transfer in most BEM software is 1-dimentional, i.e. a balcony fin will only transfer heat in the direction of its surface normal (vertically in this case).
@dradair's suggestion of Therm is a good one. It could be used to calculate the assembly's U-factor, which could be used in a whole-building model.
An easier option is to use the values from the Building Envelope Thermal Bridging Guide to derate the thermal performance of the assembly in your whole-building model.
