Hi All

Anyone had experience to modelling perforated aluminium 'shutters'. These are in fact intended as permanent guards to the exterior of full height opening windows.

I'm thinking the best way is to define the element as a window and then define an external shutter shading device in the window construction.

As they will be permanently closed, and are off-set from the window I can ignore most of the data needed to do this. But what I do need are some values for the proportions of diffuse radiation transmitted, (ground and sky).

Anyone ever done this? Have any 'typical' values?

Hi Wasted,

I did a project that implemented perforated aluminum shutters, however, my approach was different. I actually modeled the shutters as shading devices, this was probably an inaccurate method to do it, but I needed the 3D model to "look pretty" for my client... I was reading up this document at the time, which I think might be useful to you:

let us know how it works out for you please

Interesting article - I have filed it under 'interesting articles I may look at again in the future (but probably wont)' - but its nice to collect these things, so thanks for sharing.

I think what I've decided to do is to model the shutter as a solid local shade but to reduce its size to represent its 'closed' area and centre it on the window with its actual off-set. The window behind will be defined as normal with a suitable MacroFlo opening.

This will be slightly worse case in terms of solar gain because it won't properly allow for the self-shading within the holes of the shutter - but I think it will be reasonable.

Heh I know that "interesting article" folder all too well... thought it was just me :p

if the design of the shutter is simple enough to calculate the opaque area, then I suppose that's a good approximation... mine was very... "artistic"
