Advanced window technologies (triple glazing, electrochromic smart glass, low-emissivity coatings)

Buildings consume about 40% of global energy and produce roughly the same share of carbon emissions. Most of this energy gets wasted through poor insulation, inefficient heating and cooling systems, and outdated design practices.

The building sector moves slowly — most structures last decades, and retrofitting existing buildings is complex and expensive. Meanwhile, billions of people worldwide still rely on polluting fuels for basic needs like cooking and heating water, creating both climate and health problems.

Solving building energy waste requires both cutting-edge technology and practical approaches that work at massive scale. The opportunity is enormous: dramatically reducing emissions while making buildings more comfortable and affordable to operate.

Even in wealthy countries, most buildings are poorly insulated energy sieves. Heat escapes in winter, cool air leaks out in summer, and HVAC systems work overtime to compensate.

This happens because traditional building materials and construction methods prioritize low upfront costs over long-term performance. Old windows, thin walls, and gaps in the building envelope can waste 30-50% of heating and cooling energy.

Windows are often the weakest link in building insulation. Triple-glazed windows add extra layers of glass and insulating gas. Smart glass can change from clear to tinted automatically, reducing cooling loads. Low-emissivity coatings reflect heat while letting light through. These technologies can cut window heat loss by 50-70%.
