An Architecture of Energy Efficient Restroom by Making Zero Standby Power

Electronic products need the standby power consumption to stay the standby mode to reduce the total power consumption. Although the standby power is smaller than the active power consumption, all electronic products consume the standby power which is comparative to the output of 1.6 nuclear power plants annually in Japan. The toilet is one of the standby power hungry products. The standby power consumption of all toiles used in home in Japan is equal to 18 billion yen. This paper proposes an architecture of energy efficient restroom by making zero standby power. We develop a prototype hardware and demonstrate the actual execution of our proposal.
