In advance of commercialization, over 3,300unit of residential PEFC were installed and verified in FY2005 through 2008 under governmental program. In the program, system showed enough performance and reliability as future commercial product. Large Scale Monitoring Program by Japanese Government 4 Thermal Load of each House [MJ/month] The Amount of CO2 Reduction [kg/month] Five system manufacturers joined to the program, and delivered 3,307units. Toshiba delivered 748 units among them. Residential PEFC showed the performance to reduce 100kg/month of CO2 as the average.
