An external shading object can be entered in a Glazed construction.
Note: both of Local shade, which defines the projections, and External shade, which defines transmittance (either constant or profiled), must be defined to complete the definition of a Title 24 shade.
Shading Devices
Local Shade > Projections
External Shade > Shutter
If a transmittance schedule other than ‘None’ is defined, the constant Transmittance does not apply and will be hidden.
