Advanced Glazing Technologies for Commercial Buildings
Why Daylight Matters in Commercial Buildings
As sustainability and occupant comfort become central to building design, daylighting has become crucial in commercial spaces such as offices, shopping centers, and schools. Natural light enhances the quality of the indoor environment and positively influences mood and productivity. Sunlit spaces are perceived as more welcoming, energizing, and conducive to collaboration. People in such environments tend to feel better, experience less fatigue, and work more efficiently.
However, conventional glazing often falls short. In summer, it can cause overheating, increasing reliance on air conditioning. In winter, it may contribute to heat loss. Issues like glare on screens and fading of interior furnishings under direct sunlight also arise.
Modern buildings are turning to advanced glazing technologies that effectively manage light and heat to address these challenges.
Aerogel Panels: Thermal Insulation and Diffused Light
Aerogel-filled panels are an innovative solution that combines excellent thermal insulation with soft, diffused daylight. Aerogel, one of the lightest and most insulating materials available (with thermal conductivity around 0.013–0.018 W/(m•K)), is used as an insert within multi-layer glazing units.
These panels distribute light evenly, reducing glare and heat buildup. They are moisture-resistant, long-lasting, and ideal for facades, skylights, and roofs. Leading manufacturers like VELUX offer systems filled with Lumira® Aerogel. This material is eco-friendly, water-repellent, fully recyclable, and provides outstanding insulation along with comfortable, glare-free daylighting.
Electrochromic Glass: Smart Light Control
Electrochromic glass adjusts its transparency in response to voltage, allowing for dynamic solar gain and glare control. It can darken automatically based on sunlight intensity or be controlled manually.
This technology is beneficial for buildings with large glass surfaces. The glass tints reduce overheating; on cloudy days, it clears to maximize natural light.
VELUX provides electrochromic glass that can be dimmed via remote control or set to respond automatically to changing light and temperature conditions, offering an elegant solution for solar power without the need for blinds or shades.
Low-E Glass: Maximum Light, Minimal Heat Loss
Low-emissivity (Low-E) glazing features a microscopic oxide coating that reflects infrared heat while allowing visible light to pass through. It helps maintain warmth during winter and blocks excess heat in summer without sacrificing daylight.
VELUX offers high-performance Low-E insulated glass with a triple-silver coating, ensuring high light transmission while minimizing solar heat gain. This is especially beneficial in offices and schools, where consistent temperatures and ample daylight are essential.
Photovoltaic Glass: Generating Energy from Light
Photovoltaic (PV) glazing integrates solar cells directly into the glass, enabling buildings to generate electricity while still admitting light.
VELUX offers semi-transparent photovoltaic glass that delivers electrical generation, thermal and acoustic insulation, and UV/IR filtering—all in one unit. This sustainable option is well-suited for atriums, skylights, and glass roofs, helping reduce a building’s environmental footprint.
The Future of Smart and Sustainable Glazing
These technologies represent more than design innovation—they support occupant health, building efficiency, and environmental responsibility. With a wide range of materials and solutions, it is possible to tailor glazing to any climate or project requirement. Success lies in balancing performance, aesthetics, and budget while meeting the growing demand for smart, energy-efficient buildings.
