Construction, as many of you know by now, is one of the biggest single sources for waste and may be responsible for as much as 30% of the volume used in some landfills. And, because commercial space is turned over more frequently, the interior build-out of office space is one of the biggest sources of construction debris and waste. As companies change their staff, the space they occupy fluctuates, and often old spaces are torn out and new spaces built with different configurations.
Since the spaces in an office are not part of the structure (in most cases), the walls that divide offices and meeting rooms can be relatively quickly disassembled and rebuilt in a new configuration without affecting the building structure. This flexibility appeals to building owners and tenants alike, because space can be easily customized to meet the particular needs of any tenant. But it leads to an awful lot of waste, as well.
A new system of wall construction devised by Sean Dorsy, a graduate architecture student at The Catholic University of America, uses standard 4 x 8 sheets of plywood cut with slots so that the panel can be unfolded like an accordion to make a wall structure to replace standard stud construction.
