We have a project that is going to use a combined approach due to overhangs and the prescriptive calcs not providing enough SF. I have casually measured the spaces and we exceed 20fc.

LEED (Canada) is requiring minimum T(vis) of 0.4 A manufacturer has provided me information which says that their product is 33% Visible Transmittance.

There have been a few post here about using a weighted average Tvis for the prescriptive method in the case where the design has two or more Tvis values in the same plane.

Isn't it usually calculated & completed by electrical engineer ?

I know that glare control is a requirement for each window.

First off I have a slight confusion about whether library stacks should be considered non regularly occupied area or a regularly occupied area with movable furniture.

ASHRAE 189.1, 8.4.1.2 requires us to have permanent shading devices. We are attempting to achieve the Daylighting credit 8.1.
