Building facades that can dynamically absorb light in the visible and near-infrared region of the electromagnetic spectrum enable temporally-programmable optical control and improved building energy-efficiency. Conventional solid-phase chromogenic materials suffer performance limitations that might be addressed by highly-mobile, self-assembling, gas-and liquid-phase alternatives. Here, we introduce a fluidic interface for buildings that can achieve light modulation through reversible injections of air bubbles with self-organizing morphologies. We establish criteria for injection -rate-and flow-field-dependent bubble shape. And we demonstrate experimental control over visible light transmission, near-infrared light transmission, solar heat gain, and indoor temperature, through active modulation of bubble size. Energy models help predict the comparative operational performance of our system, allowing us to couple motion-sensing capabilities with digitally-actuated bubble formation, towards demonstrating the potential for a tunable fluidic mechanism in responsive building design.
