Dear Trnsys users,
I am not fully experienced in Trnsys so my
problem may be very simple to solve.
Trying to understand how to use the type 34
"Overhang" I made some tests and found strange results.
When Overhang and wingwall projections are set
to zero, beam radiation and ground radiation to receiver are
equal to same data from type 109. This is OK.
Sky diffuse is reduced a lot which does not
look normal to me.
Is there an explanation ?
Here attached is this simple
test I also need some advice on the way to use the type
34 with the type 56.
Should I create in the building an orientation for
each overhang and connect the type 34
outputs to the corresponding inputs or should I only use the fraction of solar
shading from type 34 as the external shading factor of the window ?
I would appreciate an example on the way to connect
type 34 properly to type 56
Looking forward for your help
