my question is how to calculate the sq ft area of the particular room to find out the window to floor ratio ?How to assume that the window area is covered this much area.

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.

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.

To whom it may concern, We are involving a project going to be built in Uppsala, Sweden.

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