Thermal Simulation_Energy Balance_Storage

Hi everyone,

I am running an energy simulation for a single zone which is non-adiabatic and exposed to the ground. I have encountered an energy balance with significant storage. There is no heating and cooling considered in the model. I couldn’t figure out the reason for the storage. Any leads are appreciated. I have already looked and tried the suggestions from the previous posts

Additionally, I am attaching the gh file which is enclosed in the drive location below:

Best Regards,
