        Enter the glazing and frame data for the facade. There are a number 
 of standard facade types:
         
        
            - None - there is no glazing.
 
            - Continuous horizontal - glazing is generated in 
 a continuous horizontal strip using sill height and % glazing.
 
            - Fixed height - glazing is generated with a fixed 
 height at the specified sill height, and width is calculated based on 
 the % glazing. This option uses % glazing but prioritises window height.
 
            - Preferred height - glazing is generated using 
 the window height data and the % glazing, but the window height may be 
 adjusted to achieve the required % glazing. This option uses window and 
 sill height but prioritises % glazing.
 
            - Fixed width and height - windows have fixed width 
 and height. This option uses % glazing but prioritises window width and 
 height.
 
            - Fill surface (100%) - the entire surface is filled 
 with glazing and there is no frame.
 
            - If the glazing does not have a frame, uncheck 
 the 'Has a frame?' box.
