Artemi,
If you have tmy2, why do you want to go to 109? We (Transsolar)
can create 109 files, but the scripts to do so aren't something I can easily
send you. What city are you using? Maybe I have it already. I doubt
Meteonorm can create a 109. A "109 weather file," as far as I know, only
exists in the Trnsys world. Just change parameter 1 of type 109 to 2 instead of
1 and it will know it's getting a tmy2 file and not a 109.
Variable cycles are how some Types handle multiple sets of
variables. Type 109, for example, can process various surface orientations to
create the total, direct, and diffuse radiation levels. The calculation is the
same for each of these, so the type cycles (loops) for each input
orientation, and outputs all the results grouped in the same order as they were
input.
Blocking all solar radiation to the roof might be as simple as
saying that it's 100% shaded. Or just override the usual horizontal radiation
input and set it equal to zero. I don't think you can set the roof surface
temperature directly, but you can say that the temperature "outside" this
particular surface is equal to an input, connected to the output of your
component - as if there were different ambient conditions for the roof, rather
than the normal outdoor temp.
I hope this helps.

users. I would like to ask you some things in order to solve
some of my problems, in a simulating
procedure. I used “type109”.user instead of “type109.TMY2”. How can
I convert a weather data file of *.tm2 to a *.109? Is it possible to create a
109 file using the Meteonorm
software? What is the meaning of the creation
of a cycle of variables? For example getting the weather data in a cycle means
that n new data are taken again and
again? I created a new component for passive cooling through
building’s roof. Since the new component is a roof by its own, how can I
describe that the roof of the *.bui file does not takes any solar radiation? The
new component has a variable named “roof temperature”. How can I set this value
as equal to the roof temperature in *.bui
file? Is there any way to access the kernel
of my project in simulation studio in order to check my
model? Wishing you a Happy New
Year! Yours
