Abstract
Using a result of the questionnaire of the Eco-home Diagnosis carried out 212 households in Fukuoka Prefecture in FY2012, the household attribute data, the power consumption, the CO2 emission, the heating/lighting expenses, and the countermeasure to energy saving before and after the consultationwere analyzed.
Annual CO2 emissions for the checked homes were 4,928 kg/year·household, and annual power consumption was 5,183 kWh/year·household.
The deemed reduction in annual CO2 emissions for all households receiving diagnosis was 85,018 kg/year, and the deemed reduction rate was 12.2%. And the deemed reduction in annual power consumption was 118,132 kWh/year, and the deemed reduction rate was 16.4%.
It can be said that the Eco-home Diagnosis raised awareness of energy conservation at the participating households, and it appears diagnosis had some effect in reducing CO2 emission and power consumption.
