When it comes to keeping buildings energy efficient, windows certainly pose a challenge. It was with this quandary in mind that a British scientist has created a new type of window – one that’s filled with water.
There are two main problems with conventional windows. For one thing, most of them allow heat to escape during cold weather, causing the building’s furnace to run more frequently. For another, they allow sunlight to stream in during hot weather, creating heat that causes the air conditioning to kick in.
Dr. Matyas Gutai, a lecturer in architecture at Loughborough University, believes that his “water-filled glass” (WFG) windows may address these limitations.
