Re: [EnergyPlus_Support] Selective Shadowing Calculations





Jean,
 I typically just schedule it and turn on detailed defuse modeling such as pasted below..  Did you have something different in mind?

Schedule Type Limits Name Fraction
Field 1 Through: 31 Mar
Field 2 For: AllDays
Field 3 Until: 24:00
Field 4 0.9

Dear group,

Is it possible to apply different shading calculation options to different casting / receiving surface groups? For example, I have a many facetted "tree", where I would like to switch off the mirror shading surface and increase the overlapping shadows for just these surfaces of the tree.

Kind regards,

Jean
