Environment - The aim is that the house will produce as much energy as it consumes. The energy is produced by photo voltaic cells and accumulated in batteries. "The main floor" is designed to store heat during the day and distribute it at night. The water tank can also act as a medium for heat storage. The house is designed to be naturally ventilated using the stack effect - the air intake is situated at the bottom of the transparent screens and allows air to migrate up to the top of the core at each floor. All the devices that control the internal environment of the house (sun screens, air intakes/exhausts) are designed to be manually and automatically controlled. All waste produced by occupants is designed to be stored while the house floats and when moored the waste is disposed of to the public utilities.
