[esp-r] Re: solar obstructions

Thanks Oliver.

My question was probably too ambiguous, though.  When you define an  
obstruction you can also attribute a composition/construction to it  
(e.g. extern_wall).  My question is: How does obstruction  
composition/construction affect shading/insolation analysis?  Are only  
optical properties of the construction considered?
