NC-2009 IEQc8.2: Daylight and Views—Views
We have a project that, after occupancy has taken place, would like to install a tinted film on some of the southern facing windows to reduce glare in work spaces. I am hoping someone can confirm for me that although frosted glazing is not acceptable, tint is acceptable as long as there are still views to the exterior? Is there a specific range of tint that is acceptable in this case? I cannot locate any language on this in the reference guide.
Thanks!

Tint is not an acceptable form of glare control for LEED. So if this is your only form of glare control, then you will not be able to EQc8.1. But for EQc8.2, there is not a required range in the VLT of the opening. So, in regards to this credit, applying a film will not impede in earning the credit.
From a daylighting perspective, glare may not be the issue. You could have a contrast issue which some perceive to be glare. That can be resolved sometime by simply changing interior colors or orientation in the space.
If contrast is not the problem then I would confirm that there really is a glare issue or is the space over daylit. Spaces can be over daylit which is worst than under daylit. Why, because in overdaylit spaces people block up the windows which never results in the right illuminance and then the lights come on. Which defeats the whole purpose of daylight.
