To coincide with Hokkaido Toyako Summit, the G8 summit, the Ministry of Economy, Trade and Industry, Japan is constructing a futuristic residential house the Zero Emission House.The Zero Emission House is a single-storied steel structure prefabricated house with a total floor area of approximately 200m2and an exterior that has been designed to imbue traditional Japanese beauty. The house will showcase state-of-the-art Japanese energy and environmental technology to the world, with features including a 14.5kW capacity photovoltaic generation system, energy efficient lighting, a household fuel cell, and energy saving household appliances. Construction of the Zero Emission House will be completed by the end of June, and the exhibit will be open to media professionals from Japan and overseas during the summit. The Zero Emission House goes one step beyond Sekisui House’s Carbon Neutral House in its use of state-of-the-art global warming prevention technology, and the CO2reduction achieved with its photovoltaic generation system substantially exceeds the volume of CO2emissions. Using the Sekisui House management system, zero emission of waste material has been achieved at the Zero Emission House construction site.
