Does anyone else have problems with calculation in GBS? Current release cannot calculate any gbXML from Revit wich have:
- airflow for zones in l/sq.m. units - GBS misinterprets the value and calculates flow appr 10 times more
- different temperature settings for different zones - GBS substitutes them by maximal for heating and minimal for cooling for all zones
I have been experiencing these problems for a half a year, but GBS managed to pass ASHRAE 140 test and noone else complies about results... It is strange...
At this point GBS does not have the capability to read the different zonal airflow or temperature values from your Revit file.
It's not exactly true. GBS reads different settings for airflow and cooling setpoints for different zones. The only issue is heating setpoints. In what release will it be fixed?
Our, I misread your post and now see that you are referring to a problem with unit conversions.
We will post an update on the Forum when this issue has been fixed.
I referred to both problems, one doesn't exclude another. Without solution to both GBS will not produce correct results. Looking forward to the update.
Our apologies for the inconvenience. This airflow issue was addressed in our latest release of Green Building Studio.
Regarding the temperature settings: Are you referring to the setpoint temperatures? You can export these settings to GBS for analysis with different settings for different zones, but you need to set the Revit Energy Analysis Export Category to "Spaces" and not "Rooms." Refer to this Help Topic for details: Energy Analysis using Building Elements - Detailed Workflow
Please try your analysis again.
