Hello, I carried out an energy analysis of a 5 storey open-plan office and I changed the insulation properties of the roof and the exterior walls and ran energy analysis with the same HVAC system (Packaged Rooftop Heat Pump). I expected that I would get different heating and cooling loads because of the different insulation properties. I found that there was no change in the energy analysis. Can someone please tell me what I did wrong ? I followed everything in the tutorials found on the NREL channel on youtube. Also sorry for my bad english.
Kind Regards, RMAK
