South- and west-facing floors lost screens to direct glare for hours every day. The shade overrides were so frequent that people stopped using them — half-drawn shades stayed half-drawn for weeks, and the building looked like it had given up.

We wrote a scheduler that calculates the sun's position every 20 minutes from the building's GPS coordinates and the time of day, then maps it through each floor's elevation and each facade's orientation to compute exactly which windows will catch direct light. Lutron Athena receives a per-zone choreography — shades rising and lowering across the day to block glare without dropping a wall of blackout. Each floor has its own sun curve; each window knows when its turn is coming.
