ENERGY SAVING FABRICS
Internal screens can bring substantial energy savings. In modern offices cooling is often a bigger problem than heating. This is especially true for today’s highly glazed facades. Keeping the solar heat out is a task that can be handled by selecting the right combination of glazing and shading.
Shading as a dynamic energy filter
The role of shading
Shading has an influence on the amount of energy flowing through the transparent facade. During the cooling season, reflecting out the solar radiation reduces the load on the cooling system and therefore the energy use for cooling. During the heating season, shading can reduce heat loss through the transparent part of the façade.
When looking for interior shading giving good protection against overheating, high reflectance is one of the key properties to look for. The higher the reflectance, the more solar energy will be reflected back to the exterior and will not impose a load on the cooling system. Shiny metals such as aluminium have the highest possible reflectance. Therefore, metallised fabrics will have a good energy savings potential.
There are also non-metallised fabrics having high reflectance. These can do an equally good job when it comes to heat gain control. Their glare protection performance will generally be less than adequate because light yarns are often also translucent.
The solar factor
The solar factor (solar heat gain coefficient) or g-value gives the percentage of the incident solar power that reaches the interior. The g-value of the combination of glass and shading is an important indicator for the energy savings potential of a shading solution. The lower the g-value, the higher the savings potential.
