A question about shading and insolation...
In the example below there does not seem to have been any
shading calculated for any surface.
The format of the ASCII shading file is as follows:
24 hour external surface shading
0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000
0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 # direct
0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000
0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 # diffuse - surface 1
. . .
the first two lines are direct shading (hours 1-12 and then hours 13-24)
the second two lines are for diffuse shading (hours 1-12 and then hours 13-24)
there are thus 4 lines related to shading for each surface.
To define shading from 10h00 to 15h00 at 0.29 you need to edit the last two
entries in the first direct line for the relevant surface and then the initial three
entries in the next line.
The format for the insolation section comes in two parts. The first part:
surfaces insolated by source 1
-1 -1 -1 -1 -1 -1 4 4 4 6 6 6 6 6 3 3 3 -1 -1 -1 -1 -1 -1 -1
-1 -1 -1 -1 -1 -1 3 6 6 3 3 3 3 3 6 6 2 -1 -1 -1 -1 -1 -1 -1
. . .
Each insolation source (window) can insolate up to 10 room surfaces and the
10 lines tell the simulator which surface are insolated at each hour. Each of these
lines has 24 entries (one for each hour) and a -1 says there is no sun.
A positive number is the index of the surface which is most insolated. For example
the 7th entry in the first line above is a 4 and that says the 4th surface in the room
is insolated at hour 7. The 7th entry in the next line is for surface 3.
The last section of the insolation section defines the percentage of the direct
solar radiation passing through the window that goes to the relevant surface.
If you do not want insolation calculated then you need to set that directive
in the project manager in the shading & insolation menu entry under zone
geometry.
The source code in esruish gives much more information about this.

Subject: [esp-r] How to set shading&Insolation factors?
Dear all：
I am confusd about the shading&Insolation module.Here is the document of January for a rectangular room with a window in the wall facing south.So there are 7 faces including top,base face and the window.I just want to set the window have a shading factor of 0.29 at 10:00 to 15:00.How should I edit the document?And what does the “24 hour internal surface insolation” or “matched surface insolation factors”mean?They are generated automatically. Maybe I can set them zero all?
Any answers are apreciated.Thank you!from DAISY.
