No result for cooling and heating loads in Energy model

[MansiDhanuka]

Hi I am trying to create a simple energy model for a 4 storey Building. I get results when I run these 4 floors separately. But when i use solve adjacencies to create one single building it does not give me cooling and heating outputs. I have checked for non-convex surfaces.

I am attaching a gh file with internalized geometry. Hel

This is the error message.

Running fine at my end.

Runs perfectly well at my end as well.

On another note, it is not a good idea to have one zone per floor. Better to have core and perimeter zones per floor as this will give you misleading results. For instance, in Winter, the perimeter zones may require heating and the core zone (not exposed to outside) will still require cooling. If there’s one combined zone to represent both then the heating load of the perimeter will cancel some cooling load of the core.

Here are the versions I am using.

Hi Abraham,

Thank you for checking the file. What version of Energyplus are you using currently?

Thank you

[MansiDhanuka]

Hi Devang,

Thank you for checking the file. I will remodel as you have suggested.

Thanks
