The action of ‘Cool Share’ and ‘Warm Share’ was expected to reduce CO2 emission from residential buildings. When occupants go shopping and enjoying sports and leisure, the cooling and heating equipment in their own homes would not be operating. Therefore they could share the cooling and heating in public spaces and its action would result in the CO2 reduction for the space cooling and heating in residential buildings. This paper describes the effect of CO2 reduction through the action of ‘Cool Share’ and ‘Warm Share’ in Akita city was estimated with questionnaire survey during cooling and heating seasons. As a result, a reduction of one to three CO2 tons during summer and a reduction of five to ten CO2 tons during winter were achieved through the ‘Share’ actions.
