Structural Integration Solution for the Texas A&M 2007 Solar Decathlon "GroHome"

The entry by the College of Architecture at Texas A&M University to the 2007 Solar Decathlon competition sponsored by the U.S. Department of Energy was termed the "groHome". It was based on a design system of modular units with a limited set of components that could be customized and would allow for post-occupancy expansion of the structure. The assembly of components relied on the idea of a "snap-on" joint integral with the structural steel tube column termed the "groJoint." The joint also included utility openings through the column to allow integration within the structural framework for the electrical and mechanical services for the solar-powered home. The "groJoints" were intended to accommodate beam modules as well as "groWalls" that could possibly have electrical or mechanical services, such as a bathroom or kitchen component. This paper presents the evolution of the structural system integration solution for the student-lead, designed, and constructed project; including manufacturing, welding, re-design, construction, and the extent of engineering supervision.
