CO2 EMISSIONS REDUCTION EFFECT BY LOW-IMPACT LIFESTYLE FOR RESIDENTIAL BUILDINGS IN TOHOKU AREA

A long-term investigation on energy consumption was carried out for 13 residential buildings in Tohoku area since Nov. 2002. In order to make clear the effect of low-impact life style on energy consumption, the life style menu was indicated to the occupants in 10 residential buildings, and the actions following the menu was investigated. In addition to energy consumption reported in the previous paper, CO2 emissions reduction effect by the life style menu was analyzed during a week when the low-impact life style was acted. As a result, CO2 emissions of the some investigated houses were not necessarily reduced even though the energy consumptions were saved by the actions following the low-impact life style menu. It is important to lead energy saving by low-impact life styles to CO2 emissions reduction as well.
