This study creates the evaluation criteria to analyze the $CO_2$ emission quantity in the complex of apartment house among domestic buildings and proposes how to calculate the $CO_2$ emission quantity by the only simple information of apartment house. The study shows that in order to create the index of carbon emission evaluation criteria, $CO_2$ emission quantity for its input materials in these 27 apartment houses are 445,412g-$CO_2/m^2$ for apartment building, 474,322g-$CO_2/m^2$ for the basement parking lot, 483,523g-$CO_2/m^2$ for welfare facility, 729,957g-$CO_2/m^2$ for sales facility, 743,560g-$CO_2/m^2$ for other facility, 26,782g-$CO_2/m^2$ for public facility, 43,659g-$CO_2/m^2$ for landscape, 1,113g-$CO_2/m^2$ for indoor facility, 11,251g-$CO_2/m^2$ for outdoor facility and 891g-$CO_2/m^2$ for common temporary based on the average $CO_2$ emission by facility. We can also see the analysis data that in case of using the selected factors only, the rate of error is 7.51% comparing with the emission quantity by using simplified LCA method this study suggests for the whole range of apartment houses and the rate of error is average 3.24% using selective and main materials. And this it is evaluated that we can get the result which is similar to the actual $CO_2$ emission quantity with only the simple information about the apartment house.

Global warming has become a major issue all over the world. Noting the carbon dioxide emissions as a main contributor to global warming, we studied on the methods to reduce the life cycle building carbon emissions. Green Building Certification Criteria(GBCC) has been implemented since 2002 in Korea, but it doesn't estimate the quantities of the $CO_2$ emissions. Therefore, we studied the ways to implement the $CO_2$ emissions in quantity to GBCC. We select a government building which was rated excellent by the GBCC. This office building was regarded to excellent building by GBCC but not good for energy consumption. It was found energy glutton buildings for research by the Ministry of Public Administration and Security in 2010. This part of GBCC is need to be improved.. Also LCA (Life Cycle assessment) was carried out to estimate on carbon footprint on this office building. So we need to implementing quantitative evaluation on the amount of carbon emissions by GBCC. And it is possible to implementing quantitative evaluation on the amount of carbon emissions. Through this study, we expect that quantitative assessment of life cycle carbon emissions of buildings by the GBCC. Also expect to reduce the carbon emissions of the building by improving the GBCC.

The test on the mix of PVA fiber of low carbon inorganic composite as a cement substitute found it to be satisfactory in terms of flexibility and stiffness. The result of the evaluation of the properties of low carbon inorganic panel revealed that the absorptivity was low at 8 to 9%, which is lower than the KS value of 25%. Also, the test on non-combustibility and gas toxicity found that these factors satisfied the decision criteria. In the test on heavy metals discharges, Pb, Cd, Cr6+, Hg, and As were not detected. Regarding far-Infrared emissivity and formaldehyde emission, the substitute was found to be harmless to the human body. Therefore, if the issue of shrinkage, which is a disadvantage of inorganic composites, is addressed, it is judged that it is possible to develop a low carbon inorganic composite panel with better performance.

The railway project is an essential green transportation tool that is considered suitable for the domestic and foreign policy direction of carbon neutrality, but there are some limitations, such as damaging important carbon absorption sources during construction. This study analyzed the environmental impact assessment related to carbon absorption sources of greenhouse gas evaluation items conducted during the railway project, and limitations and implications were derived. The analysis of environmental impact assessment guidelines related to railway projects and carbon absorption sources dealt with prediction and reduction methods related to carbon absorption sources, but guidelines, including environmentally friendly railway construction guidelines, lacked descriptions. Since the greenhouse gas environmental impact assessment, 83 railway project environmental impact assessments have been reviewed, but in some cases, carbon absorption-related predictions have not been implemented, or carbon absorption-related reduction measures have been insufficient. In addition, there were cases where there was a limit to calculating emissions and reduction or where the reduction value was insignificant compared to emissions. In order to supplement the environmental impact assessment in the field of carbon absorption sources related to railway construction projects, alternatives such as quantitative emission and low reduction calculation, review of the no net loss system using the total environmental resource system, and linkage with climate change impact assessment are needed.

국토교통부는 녹색건축물 조성을 촉진하기 위해 '17년 공동주택은 냉,난방 에너지 90%('90년 대비) 절감 목표를 수립하였으며, 2015년 UN 기후변화회의(2015 United Nations Climate Change Conference)에서 당국은 2030년 배출전망 (BAU)인 8억 5060만 ton $CO^2$ 대비 37%를 감축하겠다고 발표하였다. 이를 만족하기 위해서는 가장 많은 탄소 발생을 야기하는 건축물에서 탄소배출 최소화를 위한 조치가 시급하며, 이에 건물 사용 시 발생하는 탄소배출 감축을 위해 필요한 건물 성능 강화를 유도하는 커미셔닝에 대한 관심이 높아지고 있다. 그러나 현재 건설업계에서 커미셔닝은 법제화되어 있지 않고 건설 참여자의 수행의지 및 효과 홍보 부족으로 인해 활성화 되어있지 않다. 또한, 녹색건축으로의 인증을 획득하는 과정에서 조차 커미셔닝은 필수 수행 항목으로 지정되어 있지 않아 국내 커미셔닝은 그 효과 대비 저평가 받고 있는 실정이다. 이에, 본 연구에서는 커미셔닝의 효과에 대해 기술하고, 해외 녹색건축인증 LEED, BREEAM을 기준으로 커미셔닝이 녹색건축에 있어서 어떻게 평가받고 있는지 국내 G-SEED와 비교, 분석하여 국내 녹색건축인증에서의 커미셔닝 필수화를 제안하고 나아가 커미셔닝이 국내에서 활성화 될 수 있도록 건설 주체자의 인식 변화를 유도하고자 한다.
