j.Pod units as a sustainable building system

Abstract

The j .Pod unit is a new type of timber building system that uses a semi-monocoque structure composed of mainly timber rib-frames and several steel connectors. Semi-monocoque structures operate on a similar principle to the single-shell construction of aircraft and boat designs, and are self-supporting or structurally independent. This means j .Pod units are light but extremely strong and rigid with sufficient resistance against earthquake load. Tbey can also be combined in many different ways as required. The j .Pod unit is ideally suited for use in cellular type buildings such as houses, apartments and hotels. By lengthening the units' dimensions, they may also be mauipulated for application in larger building projects. The unit consists of simple components that may be easily manufactured and assembled. By constructing the unit primarily from domestic timber - in particular, Japanese cedar, much of which is not being used efficiently in the Japanese timber market - the developers of the j.Pod concept hope to revitalize Japan's domestic timber industry. Finally, the unit is expected to re-establish local networks among builders, users and timber resources that have been lost in recent years owing to an increasing dependence on the use of cheaper imported timber, the logging and transportation of which has been at great environmental cost.
