RE: [EnergyPlus_Support] Error: Heating Load is Zero

I have the same problem with large models and heavily insulated buildings (passive offices,..).

Although the heating load is calculated as zero, the requested comfort temperature is not achieved…

Still looking for the solution.

Best regards,

big model.

1) you must have infiltration loads ON for externally bounding zones...the infiltration is off as you mentioned before.

2) it may be that internal zones don't have heating loads.

I'm busy running your simulation, and sketchup is still loading the idf.

I'll let you know what I find.
