The use of natural resources in buildings for purposes of functionality is considered to be “intelligent architecture”. The reason for this is to fully understand the needs for energy savings, and therefore environmental protection. 

In normal use, a space with a general, diffuse light transmission of 5% is appropriate to carry out everyday tasks at home and work (e.g. reading a newspaper). Lower transmission grade fabrics may need to be artificially illuminated or, in contrast, spaces with too much light (UV) transmission can be found to be unpleasant by the public. The grade of natural transmission has to be carefully analysed “case by case” as this can have dramatic consequences on the final results and depends very much on the intended application of such a building.
