Radiance-general -- LEED v4 calcs (Liam Buckley)

Hi Liam,

If IES-VE does not move blinds based on solar penetration (2% criteria) as
described in LM-83, then the sDA results will incorrect. To get the LEED
credit you need to use the method prescribed in LM-83 and that means you
need to have blinds/shades that are not "static"

Regards,
Mudit Saxena

Hi Tim

Static; meaning not moving at varying hourly intervals. The blinds (as
components) are set at wherever you put them; be it always up, always down
or always somewhere in between.

If you want to see more, please join the web-demo, see the info previously
provided.

Thanks
Liam

Liam,

what does static blinds mean? The blinds are always down?

Thanks,
Tim

Dear Thomas:

First of all, thank you very much for your suggestions.

I would like to ask you for counselling regarding a problem I am
experiencing with the rendering process. I have built my Sketch up model,
and I exported it to radiance(using the su2rad_1.0_alpha version) and I?m
in the rendering stage (rpict). The problem is that the window frame
elements are not visualizing well: they appear undefined and missing some
parts (as shown in the link below).

https://www.dropbox.com/sh/lwvi9f35e0r33pv/AACqWAvwn0Wx7ybWb1OVno78a

I used 2 types of Radiance parameters, first I used the very accurate
parameter, and since this didn?t seem to improve the image I increased
these parameters, but this problem continues to happen.

I don?t know if maybe I?m doing something wrong with the su2rad geometry
exporting process because I have done this from Ecotect to Radiance before
and I haven?t had this issue.
I?m sending you the link to the folders that contain these files so you
can give me your opinion and hopefully help me to solve this.

Again, thank you for your time.
