Global Shading Day 2026

Shading is not just a summer feature — it’s a smart, dynamic solution that improves comfort and helps reduce energy use all year round. In winter, it lets you benefit from free solar gains during the day and retain indoor heat in the evening, while in summer it protects interiors from overheating. Beyond thermal comfort, shading also adds privacy, safety, and effective glare control from a low sun.

Did you know that shading works all year round?

Using shading systems to keep interiors cool during summer months isn’t new — it has been around for hundreds of years. But did you know that shading is a dynamic and flexible solution that can be highly effective throughout the entire year?

In winter, it helps keep you warm and comfortable

Shading also plays an important role in winter — helping to keep indoor spaces warm and comfortable. On sunny winter days, you can use shading smartly:

During the day, keep blinds and shutters raised (deactivated) so you can gain free heat from solar radiation to warm your home or workplace.

Research shows that by keeping blinds and shutters raised during sunny winter days, you can reduce heating energy use by up to:

• 15% in Northern Europe
• 17% in Central Europe
• 41% in Southern Europe*

In the evening, closing (activating) shading helps retain heat indoors and improves energy efficiency.

Why shading can be better than solar control glass

By comparison, other solutions — such as solar control glass that blocks solar heat from entering through windows — can cause you to lose out on free solar heat in winter, exactly when you need it most.

This means you could be missing a significant amount of free solar gains (energy), especially as more and more homes are built with large glazed areas to enjoy outdoor views.

While solar control glass is a fixed solution, smart shading is dynamic and flexible — it can be adjusted to real-time needs, time of day, and season.

Shading comes with additional practical benefits

Shading is a smart way to control heat indoors exactly as needed — and it offers many other advantages, too:

• Privacy
• Safety and protection
• Reduced glare from a low winter sun

Blinds, shutters, awnings, and other shading products are an excellent way to ensure comfort at home, in workplaces, and in public spaces all year round.
