Market Viability

(150 points)

The Market Viability contest evaluates whether the house has market appeal and is well suited for everyday living—and if it could be built easily and accommodate a variety of potential homeowners. The jury considers livability, buildability, and flexibility. A key goal of the Solar Decathlon is to help reduce the cost of building-integrated PV systems. Teams build their houses for a target market of their choosing and are asked to demonstrate the potential of their houses to keep costs affordable within that market.
