Smart windows control the sunlight and heat entering a home 

One company is giving people easy control of their windows, optimising energy usage, comfort, and desired privacy

Spotted: Windows have remained functionally the same since their invention; providing natural light and perhaps a level of aesthetic beauty to a home. However, this has meant that while the home has undergone technological smart advancements with heating, storage, electricity, and other things, windows have fallen behind.

Windows account for about 30 per cent of heat loss in a home, and during hot periods, they often let in too much solar heat, which is often compensated for with energy-intensive cooling systems. And even with the right window insulation, it’s rare that lighting is “just right” for the occupant’s comfort when dealing with shifting natural light sources.

This is where Tynt comes in. The concept is simple: windows that can regulate the amount of light that is let in based on what’s available and also the desire of the operator. This is accomplished by using patented Reversible Metal Electrodeposition (RME). 

The technology uses a small electric current to influence the properties of a metal film that rests in between the windowpanes – affecting how opaque the window appears and how much energy it absorbs. By either regulating the current up or down, the opacity of the window will range from completely transparent to truly blacked out. With this system the heat regulation of the house is also far more efficient – requiring just 1 volt to function, according to the company. 

Tynt is not in the commercial phase just yet, but you can sign up to be alerted when the first product becomes available, which the company predicts will be in 2024. 

Windows are a central part of all modern buildings, but if they’re poorly designed, they can rapidly increase the heat losses and greenhouse gas emissions of a property. In the archive, Springwise has also spotted shade screens that provide renewable sources of energy as well as this company that can retrofit entire buildings with net-zero glass to reduce heating costs.
