FABRICS FOR THERMAL COMFORT
Thermal comfort has been shown to have a significant impact on the productivity of office workers. People perform best when the ambient temperature is between 21 °C and 25 °C. Seppanen derived the relation below from 9 scientific studies on the relation between temperature and productivity.

The role of shading
Shading has an influence on the amount of energy entering through the transparent facade and therefore on the interior temperatures.
When looking for interior shading giving good protection against overheating, high reflectance is the key property to look for. The higher the reflectance, the less solar energy will be transferred to the interior. Shiny metals such as aluminium have the highest possible reflectance. Therefore, metallised fabrics will have good thermal performance.
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 European norm EN 14501 defines a scale of 0 to 4 for the influence of a shading device on thermal comfort, where 0 indicates very little effect and 4 indicates a very good effect. High reflectance interior shading when combined with solar protection glass can achieve class 3 “good effect”.
