Window Blinds

Window blind components can be selected for external glazing, roof glazing and interior glazing from the Openings tab in the Model Data.

There are five types of window blinds, as selected in the Category data on the General tab:

• Slat - slatted blinds which have different transmission properties with solar position.  
• Shade - assumed perfectly diffusing.
• Electrochromic switching - switchable visible and solar properties based on solar gain.
• SageGlass electrochromic - multi-state electrochromic glazing systems.

Note: In the case where a Window blind is applied mid-pane, any dividers that may have been specified for the window will not be applied in the model. EnergyPlus will generate a warning to this effect.

Window blind component data can be selected from the window shading data on the Openings tab in Model Data and is applied to all windows on the surface, including custom windows.

The data applies only to external and roof glazing, internal windows cannot have window blinds.
