Solar protection comes first, and active cooling systems, such as air conditioning, should only be used when necessary.

With the arrival of the summer solstice on 21 June, solar protection is a fundamental tool for improving comfort, reducing energy consumption and creating buildings that are resilient to climate change.

As heatwaves become more frequent and intense around the world, the number of air conditioning units in Europe is expected to rise to 275 million by 2050, according to a study by the International Energy Agency.

The additional energy required for indoor cooling results in increased CO₂ emissions into the atmosphere. At a time of rising energy prices, it also leads to higher costs for households, businesses and organisations.

But there is another solution. Solar shading is a sustainable measure that helps reduce, or even eliminate, the need for active cooling measures, helping us stay comfortable during the summer heat.

Using solar shading to keep cool during the summer months is not a new idea—it has been around for hundreds of years!

Modern and innovative materials, combined with smart solar shading technologies, maximise the effectiveness of shutters, blinds and awnings.

How does solar protection make a difference?

• Prevents up to 90% of heat from entering the building thanks to external solar shading systems.
• Studies show that indoor temperatures are reduced by between 4°C and 10°C with automated solar shading during a heatwave*.
• Promotes better sleep at night, a key factor for recovery, cognitive performance and overall health.
• Eliminates uncomfortable glare that can cause headaches and eye strain.

Global Shading Day is an annual awareness day held every 21 March, providing advice and expert knowledge on the benefits of solar shading throughout all seasons.

Anders Hall, President of the European Solar Shading Organisation, which coordinates GSD, said:

"Record-breaking summer temperatures and longer periods of drought, with days exceeding 35°C, are becoming increasingly common. Regions such as Southern Europe are facing critical levels of heat stress. Solar shading, and above all external solar shading, prevents the sun's heat from entering our homes, workplaces and public spaces during the summer months.

This means we can reduce the need for air conditioning and save energy. It means we can feel cooler, healthier and happier throughout the summer months."
