Any updates? It doesn't appear to integrated into this measure yet. Thanks

I'm trying to figure out exactly what openstudio does when you use the Air Wall Construction. I'm looking through the outputed idf, and don't see the air wall construction in there. Is it creating a material with very high U value? Is this an opaque construction material? I'd like to know as if its opaque then it will not be suitable for daylight and detailed solar gain analysis. I've always modeled internal openings in E+ by creating a special glazing material with close to 100% transmittance, but maybe I can skip this tedious step.

Thanks,

I tried this measure and found its currently not working for the high rise apartment (pre 1980).

Also, I would love it if you could delete these objects without going into the osm via text mode.

I've run into the same issue, helpful to see I can solve this by assigning ELA at the space level. Would be great to mak

It doesnt seem that this has been addressed in v 9.1.0. Using the approach outlined above I see minimum outside air bein

I've also found Dview to be painfully slow when loading files, sometimes I can barely even get it to open on its own. I

I also noticed this measure is creating natural gas powered elevators, which is interesting!

Ok, that's sort of confusing. So when you run the 'create DOE prototype building' for post-1980 it adds a data center si

HI Amir, do you mean the 90.1 models? I just checked, and the measure does match well for those. I was referring to

Thanks for helping Aaron. I've also pasted in the column headers directly from the variable csv output file. For exampl

Thanks Aaron, I did check that.

Thanks @mdahlhausen, not nested meters, just a meter consisting of output variables.

@JasonGlazer, yes they are. The one I'm having issues with is copied from the RDD file directly. Thanks

Also, it works fine with the 'lights electric energy' output variable: Meter:Custom, LightingTestMeter2, Electric

Any other ways to do this? I have a model with a couple hundred zones and have the same issue.

Having trouble with surface matching and finding that many spaces have floors that auto set to roof/ceiling. This seems to be contributing to the lack of matching. What causes OS Sketchup Plugin to decide if a surface is a floor or roof? Does drawing direction matter like it does in EnergyPlus? (i.e. Clockwise vs Counter Clockwise)?

Even when creating geometry carefully and 'from scratch' (rather than importing), I find I get a lot of surface matching

Got it, thanks.

Thanks, I'm not on GitHub and don't see your email on here. If you can email me hzirnhelt@rmi.org that would be great. T

What is the timeline for updating the "Space Type and Construction Set Wizard Measure' to include ASHRAE 90.1 2013? Are there any beta versions out there that could be used now? (Would be helpful to have it for office space type at least).

Thanks,

This thread suggested this was planned a while back.

I'm stuck on this error shown below:

    ** Severe  ** During AirLoopHVAC:UnitarySystem Input, Invalid Component Type input=COIL:COOLING:DX:SINGLESPEED
   **   ~~~   ** Component name=ACDXCOIL 1
   **   ~~~   ** Occurs in AirLoopHVAC:UnitarySystem = MINISPLITUNIT

This does not make sense as the I/O manual and IDD both clearly state this coil type is a valid choice for the unitarysystem object.

Additional context: trying to model a residential minisplit system (no outside air), EnergyPlus 8.9.0 on windows

Any help would be greatly appreciated, thanks!
