at much longer dimensions of with diameters, at a less than thickness. It was also waterproofed both inside and out by a coating of polyurethane to meet testing requirements for extreme weather conditions and fire protection. Surprisingly, the paper tubes are very difficult to burn due to the high density of the material. Ban's design allowed for full recyclability of the Japanese Pavilion, in keeping with Expo 2000's theme of environmental awareness. Fabric tape was used instead of mechanical joinery. The fabric tape allowed for complicated movement, and also naturally post tensioned the structure.pg32 The main tunnel of the pavilion was designed as an incredibly large space, at (L × W × H).pg135 The fabric tape was used with a buckle system which allowed for manual construction and dismantling. Due to the strict building codes in Germany and the unconventional use of paper as a revolutionary building material, the Japanese Pavilion had to be over-designed and incorporate wooden elements, thus, becoming more of a hybrid structure. An innovative design feature was Ban's use of recyclable wooden boxes filled with sand instead of a concrete foundation.pg33 Nepal Project In July 2015, Ban began a project to rebuild homes for the victims of that year's Nepal earthquake. The structures of the homes are wood framed for flexibility and built fully with brick walls. The homes are thus quickly and easily built. Also, the Nepalese can use them for many other purposes, such as schools. Teaching Ban is currently a professor at Keio University. Previously, he taught at institutions including Harvard University, Columbia University, Cornell University, Kyoto University of Art and Design, Nihon University, Tama Art University, and Yokohama National University.
