The protoype was constructed with wooden materials and was built for maximum flexibility. The building is designed to produce a positive amount of energy that could be used to share energy as part of a smart grid in its Lucerne neighborhood. Excess energy is stored in batteries, and could be used to power up electric bikes for sustainable transportation. The e-bike could also be used as a stationary bike for exercise, putting the energy produced back into the battery.
