In an era when both environmental comfort and sustainability are key concerns in architecture, the tendency to cover buildings entirely in glass is among the most criticized and controversial traits of contemporary architecture, as all-glass buildings often guzzle energy thanks to their demanding cooling and heating requirements. Over the years, a number of fixes for this problem have been attempted, including smart glass solutions that allow users to modify the transparency of the window. The problem with this solution, however, is that smart glass is unable to block infrared (heat) transmission without ruining the very thing that makes glass attractive in the first place: its transparency to visible light. That conundrum may soon be a thing of the past, though. As reported by Phys.org, a team of researchers at the Cockrell School of Engineering at The University of Texas at Austin have developed a new smart window technology that allows users to selectively control the transmission of light and heat to suit their requirements.
Smart Glass: The Latest Architecture and News
View has raised $150 million to fund their specialized Dynamic Glass tints. The new technology automatically responds to outdoor conditions or from a mobile phone, resulting in a reactive tint that reduces heat and glare. This, as the company said in a press release, allows for "greater occupant comfort and energy savings without ever compromising the view." The tinted windows have been installed in more than 100 locations across North America. The funds will be used to accelerate product development.
With the demands of sustainability today placing tight restrictions on performance metrics such as how airtight a building is, one of the sacrifices that often has to be made is user control. Windows are often no longer openable; shades and blinds often replaced with non-openable louvers. In recent years new technology such as smart glass (sometimes called "switchable glass) has promised a modicum of compromise, allowing windows to be tinted on demand. But smart glass is limited - it's either on or off, clear or tinted.
