ES-SO, the European Solar-Shading Organization and one of the umbrella organizations contributing to the Buildings Platform project, has emphasized the virtues of mobile shading techniques in publications and studies, such as ESCORP-EU25, which shows that solar shading can contribute substantially to reducing the heat load in winter, by reducing heat loss through the glass.

Avoiding overheating in summer conditions by keeping excessive solar energy out is not always recognized. According to the organization’s press release, very often, the properties of the high-performance glazing are credited with taking care of this problem, but if you want to be able to control the heat and light from the sun, an intelligently controlled solar shading device is indispensable. In some countries, within the framework of the EPBD implementation, solar shading is part of the recognized energy-saving building technologies.

Denmark for instance has regulations that take into account that the number of hours above 26°C will be cooled down artificially, even if no air conditioner is planned, whereby every kWh of electricity used is multiplied. Depending on the construction, the use of mobile solar shading can reduce or eliminate the number of hours above 26°C, which is to the benefit of the energy consumption of the building or residence. Another fine example is France, where, for example, from November 1, 2007 onwards, whenever an air conditioning system is installed or replaced, all windows (except those facing the North) must have solar shading.
