‘Liquid window’ harnesses light, heat to save energy in buildings – Thomson Reuters Foundation
Rising demand for cooling and heating in commercial buildings has pushed up their carbon emissions – could temperature-sensitive windows help?
By Michael Taylor
KUALA LUMPUR, Nov 5 (Thomson Reuters Foundation) – A newly developed “liquid window” can block sunlight to keep a building cool but also absorb heat to be gradually released during the day or night to cut energy costs, scientists said.
The window, invented by researchers at Nanyang Technological University, Singapore (NTU), uses a hydrogel-based liquid between glass panels and was found to reduce energy consumption in buildings by up to 45% compared to traditional glass windows.
