Hi, Thanks in advance for any advise.

I have run a simple model with geomotry created by sketchup, and I add some simple properties to it,such as weather conditiong, construction set.

And then I ran this model, it seems to be succeed, but failed in the last step.

Like the following picture.

You can check all my documents here.,

Some of you guys have ran my IDF file, and found no severe errors.@Jim Dirkes

First, I'd like to say it's so kind of you to try your best to help me solve the problem.

But if you guys look into the results of Energyplus carefully, you can find it really wierd.

First, there isn't any ''Building Area'' .

Second, the Envolope part isn't identified by openstutio(or energyplus) too. image description

As a matter of fact, also no ''Site and Source Energy'' in the model too. image description

Also, if you ran the osm file which is equal to the IDF file(osm file is converted into IDF file to achieve the goal of building energy simulation).

you may find the reports of Energyplus and Openstutio conflicts. (Don't forget to drag the ''OpenStutio Results'' from the library) image description

Run the osm file after add the ''OpenStutio Results''. image description

And it shows that ''Envolope Summary'' fails too(just like what the Energyplus Report said) image description

Here is the results.

Energyplus Results:

OpenStutio Results:

@Southeast are you using EnergyPlus directly (simulating IDF) or an EnergyPlus interface (OpenStudio, etc.)? Please mention it in your question's title and/or post, as well as add a tag so that others can provide better help.

Thank you, Aaron.@Aaron Boranian As for your question, I'm using an sketchup openstutio plug-in first, after I finish my geometry model I directly lauched openstutio in SketchUp. In other words, I created an OSM model in SketchUp, and open it using Openstutio. And thanks for your suggestion about adding more tags, I really want to but dont know how. When I successfully add one, how can I seperate it from the other?

A simulation will not normally fail with only "Warning". Is there a "Severe" which follows these? If so, please indicate what that line says. You may also want to attach your IDF

Thanks for your suggestion, Jim.@Jim Dirkes But there isn't any severe problem in my err document. And could you please show me how to ''attach IDF or other useful documents''.(I'm new in Unmet hours) Before that, you can browse the ''Final Error Summary'' of the err document in my next comment.

The following error categories occurred. Consider correcting or noting. Nominally Unused Constructions The nominally unused constructions warning is provided to alert you to potential conditions that can cause extra time during simulation. Each construction is calculated by the algorithm indicated in the HeatBalanceAlgorithm object. You may remove the constructions indicated (when you use the DisplayExtraWarnings option). (To be continued……)

I ran your IDF and see that you have no severe errors, n large part because there is no HVAC contained in the model. As a result, the many warnings are for a variety of fuel meters that have been defined - but have no equipment which uses those fuels. Once you define a complete HVAC system, delete the inapplicable meters and those warnings should go away.

Many thanks to your help. Please have a look at my new edited post.@Jim Dirkes

I see now that you have created a model with NO building surfaces, eg, NO walls or roof and NO windows. Since I'm unfamiliar with OSM, I can't help solve that, but it may give you a clue...

I found the reason now. It's because I didn't set a space type and boundnary conditon in sketchup plugin for the space. Thank you for your help.
