I know that glare control is a requirement for each window. The reference manual gives a list of these to be: fixed exteror shading devices, light shelves, interior blinds and louvres, fritted glazing and electronic black out glazing.
Has anyone ever heard of an instance where glazing with a lower LT could be considered as glare control?

I personally have not seen anyone make a successful argument for LEED. Now we can discsuss how low VLTs do help reduce or eliminate some forms of glare in the interior and how that effects daylight and what not, but unless you get a LI (CIR) passed through the TAG, you are going to need something else.
Personally I believe that only form of glare control device that should be accepted is some form of movable blinds or shades. Exterior shading devices or lightshelves will only block the sun for certain times and angles. The only way to cover all possible forms of glare and possible occurrences is with movable blinds. The other reason is for if and when the space becomes over illuminated with to much daylight, it is possible in spaces that are not designed with daylight in mind. Then what are the occupants left with?
