BIG IDEAS-small buildings

As discuss with a few of my tutorial members below is a picture of a self inflatable cube that was seen in the lecture today. Someone wanted to know what the material was, it is called double sided metallic polyester. one side insulates then reverse it and the other side reflects the sun. 

the 'out of pocket' cube designed Martin Ruiz de Azua, and the cube is self inflatable. inside the fabric allows filtered views of the outside. hope this helps a few people. i will add some more interesting ideas from 'Big Ideas- Small buildings' book and the second edition 'big ideas- small buildings: GREEN' in a second
