Energy savings
With modern sun shading

Energy saving potential with sun shading systems

Heat energy reduced by 30%

Save on heating costs in winter

During the cold months, the sun's radiation is directed into the rooms to provide heat. At night, air pockets between the tightly sealed external sun shading system, a roller shutter for example, and the window increases the heat insulation, preventing heat from escaping to the outside.

The use of sun shading systems at windows surfaces cuts energy costs during the heating period through simple physical principles.

Reduce cooling energy by 50%

Protection against overheating during the summer

This conventional function of the sun shading system can have a major impact on a building's energy requirement. Often, there is even no need to install an air-conditioning system, and this significantly reduces both construction costs and the running costs of properties. In summer, the sun shading system prevents rooms from becoming too warm during the day. An external sun shading system, such as external venetian blinds, which intercepts the sunrays before they hit the window, is especially efficient here.

Cooling loads can be significantly reduced with the right combination of windows and automated sun shading system.

20% less artificial lighting

Best possible daylight utilisation

In addition to heating and cooling energy, power for lighting can also be saved. According to our calculations, a sun shading system with slats combined with a good automated control can achieve energy savings for artificial lighting of around 20 percent or more. Modern daylight technology can help you to significantly reduce the current consumption for artificial lighting and save energy.

Decide on a WAREMA solution and save at least 20% of the energy required for artificial lighting!

Anyone who thinks of internal and external sun shading products with intelligent controls as just shading systems and attractive design elements has underestimated their multidimensional impact.
