ES-SO is a non-profit organisation under Belgian law that aims to promote the positive impact of solar shading on indoor climate management, thereby supporting the EU’s ambitious energy-efficiency goals. ES-SO is the European umbrella organisation of professional solar shading organisations. Based in Brussels, it is ideally located to guarantee that the voice of the industry is heard and that it can make a positive contribution to the European energy targets. 

As the Earth's climate changes, heat waves and heat-related deaths are increasing. Smart solar shading is a vital solution to prevent overheating in buildings. Each year, on 21 March, ES-SO celebrates Global Shading Day, highlighting the importance of solar shading in combatting global warming and making buildings more climate resilient.
