PROJECT CHALLENGE

Sun Tracking Glass Louvers Acting as Solar Shading

The goal of this project is to create glass louver system which can be controlled to reduce the solar loads without compromising daylight supply.

CONTROL ANGLE PARAMETER

Create list of adaptive points using XYZ cooridinate 

1. Open the mass family and get all the curtain panels and their locations.

2. Create Excel file which has XYZ coordinates of adaptive points.

3. Clean the Excel data manually using Excel Find and Replace function to become data only 

Get each panel direction

1. Read panel location data from Excel file and create a list.

2. Create panel objects as Revit adaptive components according to the list.

3. Create panel surface geometry by connecting all points.

4. Find center point of each panel and get a vector at the point.

5. If Vector Y is positive (when panel is facing North), reverse a vector.

(Panel direction without if statement)

South-facing vectors are required later to get vectors between panels and sun direction.

(Panel direction with if statement)

Calculate angle between sun and panels

1. Get sun direction from Revit view.

2. Calculate the angle between sun path and each panel.

3. Control angle parameter of each panel only when panels face the sun.

If angle between panel surface and sun direction is smaller than 45, the panel needs to be closed and angle parameter is equal to (90 - sun altitude angle)×-1

If false, the panel can be opened and angle parameter is 0.
