Adding multiple glazing on a single surface

Hello everyone,

I am designing an office tower floor which has a series of different vertical glazing and opaque (aluminum) layers.

In order to do this I used a chain of add glazing components, separating the layers with different properties. I also used the glazing component to add an aluminum composite panel (any other better way?perhaps setting the whole wall as a panel and then cut the window parts?). Everything seemed to work ok. No errors and in the preview it is clearly visible that the window is separated in layers.

However when I plug them in the create zones component they do not show up. When I plug only them, then only the first glazed surface plugged in shows up. Anything after that won’t display.

Any ideas?

Edit: Found this…, and realized the surfaces are there just not displaying in the create zones component. Will try simulations to make sure.

Kind regards,

Hi Theodore,

Unfortunately your file is missing a lot of geometry. You need to internalize all of it.


Sorry Abraham,

Attaching the file now.

I managed to run the simulation, as I said it was an issue of the layers not being displayed (probably Rhino tolerance?). But after the simulation I got some very strange results. Glazing is shown as walls, walls and the glazing over it are shown in the results, certain walls with glazing are completely ignored, etc.

I think this workflow, adding glazing one after another, is either wrong or doesn’t work. I wish we could do it as the radiance workflow, adding surfaces by type :frowning:

Hi Theodore,

At this moment i would say that if you receive any results, take them as garbage :slight_smile:

I would recommend you to master the technique you are trying to do with a simple box. It will be a lot easier to understand where the problems are.

As for your model, as far as i checked the main issue i see is this. E+ walls host the windows. The size of the windows CAN’T cover the whole wall. You need to leave even a very small part of the wall, but never cover it all with the window. You need to leave a frame (all 4 margins) of wall. Your window parts are covering the whole wall, so i think this is the main reason this is not working. But, again, maybe there are more reasons, but you need to fix this first.

Also check you are not having “extended” walls. I’ve noticed one corner where the wall extends beyond the limits. This is not critical, though.

Good luck,


Hi Abraham,

Thank you for your reply.

I have actually let it go for now (needed a break) and doing Daylight simulations. Thankfully, there the flow allows to add different types of surfaces.

As for your comment I agree, I just thought that the upper part of the wall (the COM1) which is opaque would be enough. The results were indeed garbage, and in the surface analysis it looked as if there was wall (that is COM1) behind the glazing layers. That seemed strange. I will give it a go later with gaps on the edges.

Kind regards,


Just keep in mind that your “COM1” MUST be the whole wall, not just the upper part. Over it you will
