Clerestory Glazing or any other type of glazing can be applied to a Roof for energy and daylight modelling.
Add Clerestory Glazing by selecting 'Edit Roof' under 'Building' and then select the Aspect you would like to add glazing too. Left-click, 'Select Glazing' and then set the specification of the 'Glazing'. Next, set the 'Window Placement' for 'Left', 'Right', 'Top', 'Roof Line' and 'Bottom'. All Window Placements are in meters and offset from the Aspect edges. Once complete, hit 'Save and Close'.
