Is any one used Energy plus "ANSI/ASHRAE/IES Standard 90.1 Prototype Building Model Package" before? I tried to use the outpatient healthcare models. But all of these models have a same error when opened with IDF editor: Too many fields for objects: controller: mechanical ventilation. Is any one know how to fix it in text editor?
Thanks,
The problem is that the number of fields in the Energy+.IDD file is not sufficient for the IDF Editor (it is not an issue for EnergyPlus itself). You can edit the Energy+.IDD file manually using a text editor to add fields to what ever object is causing a problem by following the pattern in the IDD. Make sure you have a comma after each intermediate field and a semicolon only after the last field. The original IDD file has the Controller:MechanicalVentilation ends with:
A146,\field Zone 48 Name
\type object-list
\object-list ZoneAndZoneListNames
\note A zone name or a zone list name may be used here
A147,\field Design Specification Outdoor Air Object Name 48
\type object-list
\object-list DesignSpecificationOutdoorAirNames
A148,\field Design Specification Zone Air Distribution Object Name 48
\type object-list
\object-list DesignSpecificationZoneAirDistributionNames
A149,\field Zone 49 Name
\type object-list
\object-list ZoneAndZoneListNames
\note A zone name or a zone list name may be used here
A150,\field Design Specification Outdoor Air Object Name 49
\type object-list
\object-list DesignSpecificationOutdoorAirNames
A151,\field Design Specification Zone Air Distribution Object Name 49
\type object-list
\object-list DesignSpecificationZoneAirDistributionNames
A152,\field Zone 50 Name
\type object-list
\object-list ZoneAndZoneListNames
\note A zone name or a zone list name may be used here
A153,\field Design Specification Outdoor Air Object Name 50
\type object-list
\object-list DesignSpecificationOutdoorAirNames
A154;\field Design Specification Zone Air Distribution Object Name 50
Following this pattern, replace the semicolon on the A154 line with a comma and keep adding fields until you get to 70 fields or so, which would look like:
A209,\field Zone 69 Name
\type object-list
\object-list ZoneAndZoneListNames
\note A zone name or a zone list name may be used here
A210,\field Design Specification Outdoor Air Object Name 69
\type object-list
\object-list DesignSpecificationOutdoorAirNames
A211,\field Design Specification Zone Air Distribution Object Name 69
\type object-list
\object-list DesignSpecificationZoneAirDistributionNames
A212,\field Zone 70 Name
\type object-list
\object-list ZoneAndZoneListNames
\note A zone name or a zone list name may be used here
A213,\field Design Specification Outdoor Air Object Name 70
\type object-list
\object-list DesignSpecificationOutdoorAirNames
A214;\field Design Specification Zone Air Distribution Object Name 70
\type object-list
\object-list DesignSpecificationZoneAirDistributionNames
I have been using EnergyPlus 8.3 after upgrading those files. I have a Energy+.idd that fixes that issue with that object that you can download here. The prototype building models can be found on energycodes.gov .
@JasonGlazer After following the procedure above I receive an 'Unmatched Object Lists Found' window when I open the IDF editor. The warning states 'The following lists appear in the IDD for an \object-list but not in a \reference or \reference-class-name: DESIGNSPECIFICATIONZONEAIRDISTRIBUTIONNAMES'
All items in the IDF editor appear correctly and I can run the simulation without error. Is this warning anything to be wary of? I'm using EnergyPlus v8.2.0 Update 1.
I am not sure why you are getting that error. Send me your edited energy+.idd file and I will take a look. Send to jglazer at gard.com
Looks like it was just some extra "tab" characters causing the problem. I just sent you a revised IDD file.
If others get the "unmatched object lists found" error after editing the Energy+.idd file, it would be a good idea to make sure no "tab" characters are used in the energy+.idd file. Many editors have a feature called "convert tabs to spaces" that should be used to see if it fixes this issue.
In order to fix the issue for any IDFs with different number of mechanical ventilation in a single loop, I wrote a short Matlab code that gives the needed lines to be added under Controller:mechanicalVentilation in Energy+.idd file. I created an Energy+.idd that has 300 objects. You can find that Energy+.idd file [here] https://www.dropbox.com/s/9nj9ro7de76.... The file is tested and there is no "tab" there. You can download the Matlab code [here] https://www.dropbox.com/s/3p7z5jlbp55..., too.
I followed all the suggestions above, and my idf file still shows the unmatched lists warning. Could this be causing my water cooled vrfs to shut off and show really low cooling consumption?
