Window Film

The film will not stop direct sun and because it would need to be placed in a way that would reduce the visual quality without the occupants being able to move it out of the way, it does not meet the requirements of the credit. The language is somewhat vague in how it describes glare. Based on the language,one could say that a dark enough glass would reduce veiling glare to a point where the vision of the occupant is not disrupted. However, a glass that dark to prevent direct solar from impacting the occupants would also probably not allow the space to meet the needed daylight levels.

Michael,

I never submitted that case. In my opinion, I think it is the valid glare strategy although LEED doesn't include that. You may try to submit this with sufficient backup information such as glare or luminance study which will meet the intent of the glare control.

In my opinion, LEED doesn't include the window film as the glare control because the reference may not be able to describe prescriptively the window film as the glare control technique. If they allow us to use window film, the next question is how much TV will be considered as the glare reduction.
Interestingly, the reference allows fritted glass as the glare control.

I am in the process of submitting a project where I am using an extremely low (8%) Tvis glazing in lites in overhead and man doors. This glazing will not have any other type of glare control (can't really put blinds on an overhead door.) But it cuts the direct component down below 500 fc. I am using daylighting from clerestory windows to meet the minimum footcandles. I don't know if this helps answer your question. Just thought I'd offer an example.

I'm also wondering why you're considering a film instead of a coating since you posted in the New Construction forum?
