TEST ROOM_ENERGY ANALYSIS SET UP

Hey guys,

I am in trouble with the preparation of the model for the energy analysis with honeybee. To better explain the design concept i will attach a jpeg file and the .gh file. The idea behind is quite simple: i have an adiabatic room, so no sun exposure, and a surface expose on the south. This surface is discretize by nine opaque's panels, A in the jpeg file, and three glass surfaces, B.

I set up the model in this way:

- five adiabatic surface;

- two different type of materials for glass (B) and opaque part (A) of the surface.

The problem seems to be after the Honeybee Create Zones component. If i give the same material, glass, to hall the surfaces it works fine.

I cannot identify the problem with this process. Can someone help me?

Thanks in advance to all of you guys!

Best

Angelo

Angelo,

Windows for EnergyPlus need to be assigned as sub-surfaces of a base surface, which I see that you are doing in you GH file. However, the sub surface must not go all of the way to the edges of the base surface (it must be smaller than the base surface). If you just scale your window geometries around their center points by a little bit before you add it with the addHBGlz, everything should work fine.
