New net-zero glass reduces heating costs

Entire buildings can be retrofitted with the energy-efficient windows with minimal disruption to tenants

Spotted: The energy crisis is impacting everyone, and the situation has only gotten worse with the invasion of Ukraine. What has become apparent over the years is that as energy prices have risen, inefficient designs and techniques have played an increasingly big part in contributing to the financial costs of living and working in older buildings. For instance, a building with inefficient windows will lose around two-thirds of its heat through the glass.  

Now, a patent-pending innovation by LuxWall called Net Zero Glass reduces building carbon emissions and energy consumption by up to 45 per cent. The windows consist of two vacuum-insulated coated glass (VIG) panes that are installed from inside the building, making it much quicker and easier to retrofit as tenants experience minimal disruption.  

The panes act like a thermos bottle, reducing the transfer of heat and cool air via convection, conduction, and radiation. Heat from the sun’s rays is reflected, and HVAC conditions inside the structure are blocked from leaving the space.  

The company recently closed a Series A funding round that raised $33 million (around €30.8 million). The funds will be used to scale production at the business’s first purpose-built commercial factory. If the glass technology is used widely throughout the world, the company could support an annual global carbon emission reduction of more than half a gigatonne.  

Springwise has spotted window technology providing a range of new services, from Wi-Fi alternatives to nature scenes for rooms without access to natural light or green views.
