On October 31, 2007, Osaka Gas Co. of Japan announced that an energy-saving house in Saito Asagi, Ibaraki City, Osaka Prefecture, equipped with a "double-generation system," which is made up of a co-generation system using a household-type polymer electrolyte fuel cell and a solar photovoltaic system, would be open to the public from November 3, 2007. The house will remain open until the end of May 2008.

The fuel cell is rated at one kilowatt and simultaneously generates power and heat, with the heat being effectively utilized for heating water. The combination of the 4-kilowatt photovoltaic system and this fuel cell enables the average household to reduce primary energy consumption by about 55 percent and carbon dioxide emissions by about 70 percent over conventional systems.

Moreover, although blinds are typically set inside of windows, the blinds in this house are set outside of windows in order to cut sunlight in the summer, while absorbing thermal energy from sunlight in the winter and transmitting it to the specially designed walls; thus, energy requirements for heating and cooling are reduced. With the latest gas facilities and home-security systems, visitors can enjoy experiencing the exceptional functionality this concept house offers.
