実測調査に基づく高断熱・高気密住宅の建設から運用までのCO₂排出量

在来木造戸建住宅のLCCO₂評価に関する研究　その１

抄録

CO₂emissions from the construction and use of houses have been increasing. In order to promote the reduction of CO₂ , it is necessary to know the exact amount of CO₂ 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 CO₂ emissions from both the construction and two years use of the house was 389.07kg-CO₂/m².
4) The authors recalculated the amount of CO₂ emissions into the amount of CO₂ emissions per area of ceiling, floor and outer wall to discover the relationship between CO₂ emissions from the construction and CO₂emissions from use of the house.
