Penumbra shading system, the horizontal trick allows light to permeate deep into a building while preventing direct sunlight from coming in. To demonstrate the concept, Short created a 3D animation showing a complex system of cogs and gears that could theoretically be used to power the system. Although the concept seems highly unlikely to ever become reality, the visual impact of a mechanical wave of louvers extending out from a building is nonetheless breathtaking.
This project was designed to offer a kinetic and mechanical solution to a problem that would otherwise be nearly impossible to solve with static architectural components: providing shading across a building facade for both low evening sun and high afternoon sun conditions. Put into motion, the shades create an undulating ripple across the facade.
