Global Shading Day

Global Shading Day raises awareness about the benefits of solar shading for people, ecology, and the economy. Given the accelerating pace of climate change, implementing solar shading standards in building legislation is a logical step. Unprotected glass allows excessive heat into buildings, leading to overheating and health issues. Shading glazing is a passive cooling solution, vital for energy efficiency.

Each year, on 21 March, ES-SO calls for attention to solar shading, highlighting its importance in combating global warming. A scientific study by Guidehouse shows that solar shading can reduce CO2 emissions by up to 100 million tonnes and save €285 billion in Europe by 2050. Buildings account for 40% of energy consumption and 36% of greenhouse gas emissions. Without action, the demand for air conditioning is projected to increase by 60% by 2050 due to climate change and heatwaves.

ES-SO advocates for the inclusion of mandatory solar shading within the European Energy Performance of Buildings Directive (EPBD)

Making solar shading a mandatory technical building solution is a crucial step towards prioritizing passive cooling in buildings. By integrating solar shading into building management systems, we can intelligently and energy-efficiently manage heat and light. These sustainable passive cooling systems not only provide control over daylight but also contribute to residents' well-being and functionality. Additionally, solar shading solutions serve an insulation function for windows during winter.


If we don't act now, by 2050 nearly 50% of buildings in Europe will use active cooling. Let's be smart for our health and our planet and make a better choice!
