InternalMass should use a 'Zone or ZoneList or Space or SpaceList' name like loads do #9141
Comments
@jmarrec I agree this would have been better as a single field. Based on the logic currently in #9132:
I should make a few more tweaks in #9132 to fix these items and add a note to the Space field (and make sure the docs are clear). All of this is more support for making this a single field. |
To make this more useful with lists, I would suggest adding one or more fields to allow the internal mass area to be scaled by floor area, and possibly by occupancy (since furniture might scale by the number of persons). |
I totally misread the IDD comment when a ZoneList Name is entered. I read that as "it something is entered in the Zone or ZoneList Name". Got it now! FYI, this is what OpenStudio uses for InternalMass: it references a definition, a Space or SpaceType class, and a multiplier. The Definition object can be absolute, per floor area, or per person. We handle the conversions in the ForwardTranslator.

#10659 cleans up the space handling (without merging the two fields). Tried to add the Surface Area Calculation Method options, but floor area and number of people aren't know yet when the surfaces are read in. Finding the right spot to adjust the area (and any other related items like zone total surface area) will take some effort to get right. Too late to cram that in for 24.2 I/O Freeze. |

Shouldn't InternalMass be changed from
to
An IDD Change might not be a good idea at this point though.
But: if you try to write 'Space Or Space List' field, input parser throws because Zone or Zone List field is empty
If I write both Zone and Space names, it seems to run. But then the IDD comment
\note This field is ignored when a ZoneList Name is specified for Zone or ZoneList Name.
is wrong no?Details
