This dynamo tool is for architects and designers who want to apply passive shading strategies early in the design process. It automatically places horizontal or vertical louvers along any selected surface or wall in Revit.

Users can specify orientation, spacing, rotation angle, and material, and the tool will instantly generate and extrude louvers flush to the wall. A built-in visualization feature assigns preview colors based on selected materials, and an optional export outputs a spreadsheet detailing louver quantities, surface area, construction cost, and estimated shading performance, making this a great early-stage design and sustainability analysis tool.

Inputs:

Input Name
Description
Wall Face
A selected Revit surface on which to generate the louvers
Orientation
Slider to switch between horizontal and vertical louvers
Spacing
Slider controlling distance between adjacent louvers
Louver Depth
Slider controlling how far each louver projects out from the wall surface
Louver Width
Slider controlling the width of each louver
Rotation Angle
Slider controlling degrees to rotate louvers around their center axes
Material Selector
Slider to choose louver material from a preset list

Outputs:

Output Name
Description
Louver Geometry
A series of solids representing the louvers, aligned and placed across the wall
Preview Color
Colored preview of louvers based on selected material (for Dynamo preview only)
Louver Count
Number of louvers generated (based on wall length and spacing slider)
Total Surface Area
Sum of surface areas of all louvers, for shading and thermal analysis
Construction Cost
Estimated total cost based on material selection and surface area
Shading Performance
Estimated sun-blocking score
Excel Export (Optional)
Table of all outputs as a spreadsheet
