I used revit to create the geometry and export gbxml model used for openstudio. I import the gbxml file into sketchup, the geometry looks good. However, when I checked the interior floor and ceiling, I found that the interior ceilings were treated as floors while interior floors were treated as ceilings. Therefore, the ground floor has no ceiling while the highest floor has no floor. This causes the "severe":
Severe * ComputeIntSolarAbsorpFactors: Solar distribution model is set to place solar gains on the zone floor, * ~~~ * but Zone ="THERMAL ZONE: SP-1001-10TH" does not appear to have any floor surfaces. * ~~~ ** Solar gains will be spread evenly on all surfaces in the zone, and the simulation continues...
I can still have the results which seem not bad. Has anyone had similar problems? Does the error affect the simulation results?
