Abstract

Recently, construction industry has been seeking various countermeasures to realize eco-friendly and sustainable development and resource recycling construction industry. Meanwhile, currently, detached houses that a lifetime limit comes account for a considerable proportion in Korea. For such reason, the problem with the increase in construction waste and environmental pollution are expected. Therefore, this research carried out a study on indicators of demolition waste generation and $CO_2$ emissions in end-of-life(EOL) phase for 854 detached houses. For that, this study calculated demolition waste generation by detached house type using volume of material data in buildings investigated before dismantling. In addition, the data of the specifications on the equipment applied in EOL phase of the building through field investigation and existing literature was constructed. As a result of this study, it was found that demolition waste generation indicators by type were RC house: $2048.65kg/m^2$, brick house: $1170.74kg/m^2$, block house: $1053.59kg/m^2$, wooden house: $999.79kg/m^2$. And $CO_2$ emissions by house type were found to be RC house: $11.273kg/m^2$, brick house: $6.847kg/m^2$, block house: $4.629kg/m^2$, wooden house: $4.864kg/m^2$. But, the $CO^2$ emission in the demolition and transportation stage of RC/brick house was similar levels to the value. On the other hand, the $CO_2$ emission in the transportation stage of block/wooden house was higher than one of demolition stage in EOL phase.
