19 university teams from across the world are gearing up to make their way to Washington D.C. for the Solar Decathlon. Last week,we previewed the 19 designs and, by popular demand, today we’ll be sharing more info about SCI-Arch + CalTech’s design. Entitled CHIP (short for Compacted Hyper-Insulated Prototype) the residence’s geometry is designed to respond to the sun’s orientation while wrapped in a sun performative envelope. More about CHIP, including a video walk-through, after the break.
While all 19 entries into the competition certainly redefine the aesthetic of a residence, SCI-Arch and CalTech’s seems to take it a step further. At first glance, one is simply intrigued by the puffy material wrapping the geometric form; and yet, of course, the look functions beyond a mere aesthetic shock value. Constructed using low-cost billboard material fastened with zip ties, dowel rods, and lag screws, this vinyl-coated fabric mesh “turns conventional wisdom on its head, wearing its thermal performance on its sleeve.”
By separating the structural members from the insulation layer, and wrapping the insulation assembly in a flexible vinyl membrane, CHIP’s exterior envelope has an extremely high R-values necessary for a Net-Zero house, at a significantly reduced cost, all the while indexing this performance in its physical appearance.
In terms of massing, the form is tweaked and shaped to find the balance between an optimal roof angle for year-round solar energy collection, and a comfortable, vaulted interior space with a minimal footprint. On the interior, the slight change in level divides the house spatially without compartmentalizing.
Other technologies include a whole-house fan that performs a complete air change in less than 20 minutes, a custom iPad application that displays real-time energy use, controls the shades, and provides instant feedback and 3-D cameras that track movement in the house and adjust the lights accordingly.
We wish the team, and its 18 competitors, luck in the upcoming weeks. We can’t wait to see the built result!
