DIVA Community - 

Am I right in concluding that when using the DIVA Grasshopper workflow you cannot directly simulate the ASE and sDA shading controls required for LM-83 and LEED v4 daylight credit requirements?  I know you can do it in DIVA-Rhino, and I know that I could set something up to post process two different simulation runs in Grasshopper to mimic LM-83, but I wanted to make sure I understood all of the current manual/automatic shading simulation capabilities in DIVA Grasshopper and that I wasn't missing something obvious.

It seems like we could set up a 2% ASE trigger using the manual shading workflow, but this would induce the lightswitch algorithm for blind control and would thus over-penalize when comparing to LM-83 and its ideal active occupant scenario.

If this isn't possible with the DIVA Grasshopper 4.0 components, is this going to be available in DIVA 5?

Hi Jacob,

Apologies for the late reply. Yes -- you are correct that the LM-83 recommended shading control is not available by default using the Grasshopper components.  To mimic the 2% trigger, you should create auto shading sensors from your grid and specify a threshold >2% of them.  See my response to this post.

And yes, this will be a default feature in DIVA 5.


Long overdue, but thanks Jon for the replies!  Just curious, ETA on DIVA 5.0?
