CO_2 emissions from the construction and use of houses have been increasing. In order to promote the reduction of CO_2, it is necessary to know the exact amount of CO_2 emissions from houses. First, the authors measured the exact weight of the construction materials and waste. Next, the authors researched the inhabitants' daily schedule and measured the energy consumption from using the house. The following results were obtained. 1) The authors discovered the relationship between the energy consumption and the inhabitants' daily schedule. 2) The amount of electricity consumed was 30.6GJ/year for the first year and 28.9GJ/year for the second year. 3) The amount of CO_2 emissions from both the construction and two years use of the house was 389.07kg-CO_2/m^2. 4) The authors recalculated the amount of CO_2 emissions into the amount of CO_2 emissions per area of ceiling, floor and outer wall to discover the relationship between CO_2 emissions from the construction and CO_2 emissions from use of the house.
