[EnergyPlus_Support] Re: About Ground Temperatures
Linda,
May I ask another question regarding the SLAB programme?
In the 'Lecture 24: Ground Heat Transfer' file Page 24, it siad 'run the building in E+ with an insulated slab or as a partition to obtain monthly inside temperatures', and these temperatures will be needed in the slab programme. I have two zones on the groung floor, which zone I should read for the inside temperatures or should I build a single zone on ground floor for ground temperature cal purpose? Or my approach is completely wrong?
Many thanks.
