Louver Shading lets you visualize the annual shading performance of a louver shading system, such as slatted window blinds or a trellis. The tool accepts a location and the dimensions of the louver system as inputs, and produces a chart depicting the amount of shade it produces for each hour of the day, for each month of the year.
