[Equest-users] How to Model Series of Louvres on Windows?

[Nick Caton]

Omer, 

I'm certain you are not thinking through the building shade approach in a time-efficient fashion.  The quantity will almost certainly be less than 5x859 when you consider a single shade can span multiple windows.

That said, an alternative may be to instead determine an effective shading coefficient for the exterior shading system using something like eQuest(!) to compare a single window of your actual glazing materials & with defined exterior shades against a base case of 1/8" float glass.  The resultant SC (which should account for values through the year as solar angle varies) could then be applied to all your windows defining no shades.  Check out the following presentation which follows this course in detail using ecotect: http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0CCEQFjAA&url=http%3A%2F%2Fisites.harvard.edu%2Ffs%2Fdocs%2Ficb.topic831443.files%2FWK4-Salhia_Shading%2520Coeffficient.pdf&ei=xDmHUIusH4jq8wTAlIDgCg&usg=AFQjCNHp_ef-knFVuaP_x8eV3fXyMDZ3KA&sig2=OJ4FmDXoBXWiNunMI0XBDw&cad=rja

Then there's always space multipliers =)...

Best regards,

~Nick

Hi,

This means creating a building shade for each horizontal louvre, I guess? With 5 louvres on each window and 859 windows, this would mean
4295 building shades. Is this possible in eQuest? Isn't this overkill and wouldn't it considerably slow the simulation run?

Thanks,

It helps to have some Revit experience as Vasari uses a push-pull method parametrically tied to dimension annotation. Once you create the geometry, run the Vasari energy analysis, disregard the results, and export results to .INP. Now you can extract the geometry under the building shade heading from the Vasari INP and paste into your Equest INP.
