EnergyPlus assumes that surfaces below z=0 are below-grade (i.e., no solar or wind exposure). If this isn't the case, just move your whole model upwards. However, z=0 seems like a pretty good reference point for grade.

I am getting fatal error as below,  I have an important paper due soon, I have been trying to create this building model since 2 months now. I have attached my idf file if you could please go through it. I did enter appropriate boundary condition as ground for basement still I am getting the error. So if you could please help me solve this error. thank You.
