Transportation across the country and set-up time in Washington D.C. were major design drivers for the Solar CalPoly team. Because the house has the longest land mass travel distance of any of the 2005 Solar Decathlon entries in order to get to the National Mall and because of the team's desire to minimize the use of fossil fuel, the team agreed on a "one truck" solution. The result was the design of a simple, straightforward architectural volume which could be pulled by a single semi tractor/trailer. The team used pre-fab construction not only to minimize construction logistics on the Mall, but also because Solar CalPoly's pre-fab prototype could serve as a useful example of alternative housing, particularly in the state of California. The primary structural material for the project is structural insulated panels (SIPs). SIPs are an engineered wood product that consists of two outer oriented strand board (OSB) skins with an inner core of expanded polystyrene. The standard R-value is approximately 4 per inch of SIP thickness.
