I think that the software license requires the plug-ins be considered part of the Energyplus application, and under DOE license. So DOE maintains ownership of all contributed code. I could be wrong on this point. You have to pay for a developer's license as well. The code is the best documented in the field. (F90)

ESP-r is great for digging around and finding algorithms with a debugger, and it seems you have computer skills. Highly efficient, but since it was grown on fortran, there are a lot of short variable names to deal with. (F77/F90/C)
