Views through roll-up doors

Views through the perforated doors is not acceptable. Similar to not being allowed to consider views through fritted glass. The view must be through a clear glass. I assuming the perforation is pretty small with an openness factor of 20% or less.

There is probably a point with the design where the amount of openness makes having these doors irrelevant and that same amount of openness probably gets close to the possibility of having views. If the perforations where the size of a window that could be placed in the door, then you might be able to make an argument. However, there is a LI out there in regards to the size of windows in fold up doors and what size would actually be considered a view window. I'd have to look for that one.

Todd, you may be referring to LI ID#2304, the project was using 6" high glazed openings in roll up doors and that was not applicable for NC v3.
That's surely means Rosamaria, if you plan on using openings in roll up doors to comply with the credit, they should be higher than that.

That's the one.

I am confused about frit not being allowed for a project - The LEED Reference guide recommends introducing etching or fritting patterns to ward off birds from flying into a larger areas of glazing but does not state that it is not allowed in order to earn this credit? We have a project in the middle east with etching on one façade.

You can have fritting or etching on the façade, it just cannot be within the cone of vision/ view glass area. So if its below 42" and above the 90" you can still use it on the façade.

The intent and requirement of the credit is to provide the occupants with the best quality view to the outside as possible and having etching and fritting within the cone of vision obscures the view. This is why you can only have views through some many layers of interior glass.

Todd, I appreciate your response. I am very curious where this information comes from as I do not see it anywhere else (Ref guide, LEED User other than your previous comment, USGBC.org.) Did you have a reviewer flag this in a project? Thanks!

LEED Interpretation #1646. Its the only one that is still in the library that addresses the issue. The inquiry notes about using clear glass panels above the partitions instead of translucent. Notice it references previous CIRs, well those were removed. But they did specifically address that frosted, translucent, and even fritted were not acceptable for providing views.

That is as close as you will get for something specific.
