공동주택 건물의 상수도 절감량에 따른 CO₂배출량 저감효과에 관한 연구

Abstract

The current worldwide interest in environmental issues has moved from energy conservation to CO₂emission reduction. Recently, according to the increase in demand for water resources, insufficient potable water circumstance is supposed, unless there are corresponding in crease in water conservation and water recycling. This study has attempted to analyze CO₂emission reduction by water saving strategies like installation water saving devices, rain water harvesting and grey water system. To do this, this research investigates applicable water conservative strategies by literature review and calculated total water saving. The results show that (1) firstly, the water usage and CO₂emission could be reduced up to 44%, (2) CO₂emission reduction by water saving devices and rainwater harvesting system is about 47.7%, and (3) water usage and CO₂emission reduction by grey water system is about 66%. In the future, this paper will be utilized for water management from the early design stage to maintenance stage of water glutton building.
