Hello all,

I have a question about RESFEN that I'm hoping this list can help me get my head around. RESFEN is developed and maintained by LBNL and I believe runs off the DOE2 engine. The software is simple to use because of its limited inputs, however I want to change one of those restricted inputs.

I'm trying to change the boiler performance which I think I can do by editing the building description file (which RESFEN labels as a .d2 file). I've attached the file and saved it in a .txt format for all to see.

My question is: Can someone proficient in the DOE2 language help me decipher where and how to edit the efficiency of the boiler in the attached file? I don't know the part load, just that the boiler in question operates at 60% efficiency. If this is to broad a question please let me know and I will attempt to clarify.

Thanks in advance!
