Frei Otto (1925-2015)

2015 Pritzker Architecture Prize Jury Citation

…Taking inspiration from nature and the processes found there, he

sought ways to use the least amount of materials and energy to enclose

spaces.

He practiced and advanced ideas of sustainability, even before the word

was coined.

The secondary skin acts as a so-called cool jacket by reducing the amount of

solar heat gain into the building – critical for Houstons sunny climate.

Invisible solar radiation is captured by the cool jacket and vented to outdoors. Initial investigations show this strategy allows windows which are 40% larger

than a traditional window wile reducing the space cooling load by 28%.
