Earth Day: conserving resources – right at the building level.

Earth Day highlights the importance of using resources responsibly. For buildings, a key question arises: how can energy consumption and comfort be optimized at the same time?

A crucial lever lies in solar shading.

Large glass surfaces provide plenty of daylight but also heat. Without effective shading, rooms quickly overheat in summer. Cooling demand increases, driving up energy consumption. In winter, solar gains often remain underutilized.

External solar shading is designed to tackle exactly this challenge. It reduces heat gains in summer and allows solar energy to be used in winter. Combined with automated control, the system adapts to sun position, time of day and temperature.

This can significantly reduce the energy required for cooling, heating and lighting. Savings of up to 40% are possible, depending on the building and its use.

Solar shading thus becomes an integral part of energy-efficient buildings.

A practical example is the D-Vision building in Bellinzona, where Solozip^® is used. The system enables precise shading while supporting the overall architectural concept.

On highly exposed façades, the benefits are clear: reduced overheating, usable daylight and seamless integration into building use.

Intelligent shading improves comfort and reduces operational energy demand. Users benefit from pleasant indoor conditions and more stable temperatures, while planners and owners gain improved building performance.

Sustainability starts with production. Griesser uses CO₂-reduced aluminium to conserve resources from the outset.

The effect becomes visible in everyday use: stable indoor temperatures, more natural light and measurably lower energy consumption.

Earth Day makes these connections visible. What matters is how these solutions are implemented in real buildings.
