Honda Smart Home System Experiment Results

Article of Honda R&D Technical Review Vol.29 No.1


An experiment has been carried out over a period of approximately three years using the Honda Smart Home System, which comprises micro combined heat and power generation system in combination with photovoltaic power generation, electric vehicle, and Smart e Mix Manager and is conceived to reduce CO2 emissions from ordinary homes to one-half and then eventually to zero. The purpose of the experiment was to study the effectiveness of the system in reducing CO2 emissions from the home, to examine the issues involved in reducing CO2 emissions without lessening the quality of life, and to explore possible approaches to achieving zero CO2 emissions. At a building identical to the experimental house, electric power was purchased from an electric utility company and a highly efficient gas hot water heater was used to make hot water on the assumption that a conventional household was consuming the same amount of electric power and heat as the household where the experiment was conducted. The result was that the experimental house achieved a 51% reduction in CO2 emissions. When solar water heaters, biofuel, and other such renewable energy sources were used, a potential direction was found for achieving zero CO2 emissions.
