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.
