Fatal error : opaque surface and window construction(Solved)

Hi everyone!

I'm a new french user of DB, and I've try to design a big building. Unfortunatly, when I try to run the simulation, i get the following message :

I don't really understand the message "** Severe ** GetHTSubSurfaceData: Surface W_35418_7_0_0_0_0 has an opaque surface construction; it should have a window construction."
What does it really mean for energy plus:?:

I first thought that the matter come from the material that i use, but i get the same error with the template already in DB library.
Can you help me, have you got any idea for me?

Thank you very much ,

Valentin

Hi Valentin,

The simulation fails because the number of layers on your glazing construction 'Projet de vitrage de toiture' has zero layers. I'm not sure why the zero layer option was in there but you should enter a value between 1 and 4. In future versions you will not be able to set zero layers.

By the way, it's a really nice model. Did you create it by drawing the profile of the building and extruding it horizontally, then cutting the building horizontally to create the stories?

Would you mind if we displayed a image of the model on our Visualisations webpage with some text to say that it was set up by you (a new user)?

Hi Andy!

Thanks a lot!
My simulation works fine now, but I get an other error. Energy+ said that I have non convex area so I need to run the simulation in full exterior mode. Well.. even if I am in Full exterior mode, I get the same message of error... It's strange, can you help me?

Thanks for the compliment! I drew the profile of each story, and extruded it horizontally. BTW, I would like to do something more complex on the building : I need to make a kind of hole in the north face of the building (like in the picture), but I have no idea how to proceed. Can you also help me here?
No problem if you display it on your visualization model, it's great!

Thank you in advance

Thanks for allowing us to use your model on our website!

First on including the 'hole'...

I think the only realistic way to include the 'hole' on the North face of the building would be to draw it in at the time of drawing the stories. You would have to start again with geometry to use this method.

Step 1. Draw the stories first but this time in plan view and extruding upwards using the dimensions of the largest storey. Use outline blocks without the sloping in the vertical but with the 'hole' on the North facade.

Step 2. Then draw a second similar large outline block to give the profile of the building alongside. This second building will be used to define the planes you will use to trim the storey outline blocks to give the vertical slopes.

Step 3. Then use these planes for cutting (read up documentation on cutting tool).

Step 4. Then convert the outline blocks to building blocks.

Ok I get it!
I try right now and i show you the result!

Thanks!

Laurent_support figured out what was the matter with convex area : you need to be in full exterior for the simulation AND for the conception of air conditioning,if DB calculates automatically the dimension of the air conditioning system.

Best regards

OK thanks for letting me know - I won't bother with the screenshots then!

Hi,

your solution works fine, but I think that the geometry of my building is too complex. The "hole" is not vertical, it's parallel to the curve of the curtain wall at the basis of the building, and get more vertical at each floor.. well, it's not very important, it's was just for the beauty of the building, not for the acuity of the simulation...
(but if you have a solution... Very Happy

)
Here is a little drawing of the profile of the building, with the "hole".

Regards,
Valentin

Looks like you didn't draw the 'holes' exactly lined up with the storey below when drawing the original stories? The original stories need to be all the same with the 'hole' looking like a slot going right up the building. Then use the profile of the outline building to cut the building to shape.

I've uploaded some images that may help you - they don't correspond exactly to your building but hopefully will convey the idea!

In fact it seems that your solution is good, but just for convex surfaces, not for concave one, because when I use the cut tool, it cut too much building like you can see in the jpg.
