For the 2015 Solar Decathlon Building Competition, Cal Poly State University designed and build the INhouse, integrating a few smart passive solar features.
Some of the home’s features include:
- Clerestory windows to allow hot air to leave the building
- Palm oil, used as a phase change material, in the home’s core as the thermal mass to help stabilize the home’s temperature
- Walls and roof made from SIPs (structured insulated panels)
- A folding window wall that extends the living area to the sheltered deck
The INhome has an attractive layout designed for a warmer coastal area that levereages the temperate environment to its advantage by allowing the home extend to the area of the southern deck, shaded by solar panels.
The team finished in 3rd place overall. Additionally, team Solar Cal Poly tied for 1st in commuting and received 2nd place in market appeal, 2nd place in home life, 3rd place in architecture, and 4th place in engineering.
