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.

Hello - Could you please confirm the measurement height for the daylight readings? Is this the workplane, floor, or other height? Thank you very much - Candice

The credit language for c8.1 is states: "However, designs that incorporate view-preserving automated shades for glare control may demonstrate compliance for only the minimum 0.150 value" I'm I c

I am not finding any parameters for the daylight measurement option as far as times of day or other issues.
