In 2023, researchers modeled fluid-filled microchannel windows; computer simulations estimated the liquid system could cut building energy use by 43 percent

Researchers are developing innovative liquid windows that can control heat and light transmission. These tunable windows could potentially reduce building energy use by an estimated forty-three percent. Microscopic channels bonded to glass carry fluids, adjusting thermal and light properties. While still in development, this technology shows promise for future energy savings. Commercial buildings could see substantial reductions in heating and cooling expenses.
