Abstract
The objective is to clarify the influence of CO_2 emission caused by the equipment in the wooden detached house. In this study; pipings, wirings, furnishings, home electric appliances and furniture were defined as 'equipment'. The result showed that CO_2 emission related to manufacturing process of the equipment was about 20%. And with the using process of the equipment included, it was shown that CO_2 emission caused by it occupied 60-80%. In addition, dipending on the specification differences in selected equipment, it was caught that the result of LCCO_2 varied within about 10%.
