Re: [EnergyPlus_Support] Grate as solar protection



Geert,
I don't know what you mean because I do not understand how this grate might be installed. Is it movable or stationary? How thin?

Assuming stationary, perhaps the transmittance schedule could be created to reflect the approximate net transmittance each month?

Jim,

what about the grate angle when tilting the component block ?

Geert,
How about making a DesignBuilder component block (Shading:Site:Detailed) with non-zero transmittance that corresponds to the grate's open area?

Has anyone experiance with modelling a grate (typical 44x44 mm) used as solar protection?


I have a client who wants to use such a grate under 45° to protect his building from the sun.

I could draw the grate in Designbuilder, but the dimensions are to small and the total surface is to large.

Is there a way to model such a solar protection in an alternative way?

Geert

There are two basic choices when considering our world: 
1) it is all random happenstance
2) it was created with a purpose
Believing #1 can only result in anarchy. I pick #2 and work on discovering / living out that purpose.
