국내에서 기 개발된 $LCCO_2$ 평가프로그램은 실시설계 이후에 자재물량을 직접 입력하는 방식으로, 최적의 환경부하 저감 전략을 입안하는데 한계가 있었다. 이에 본 논문은 계획단계에서 비용대비 에너지 효율이 높은 방안으로 신속하게 대응하면서 정확성이 높은 시스템을 구축하기 위한 필요 요소를 추출하고 제안하는 것을 목적으로 한다. 이를 위하여 기존의 국내외 $LCCO_2$ 평가프로그램을 비교분석하여 계획단계에서 건축물의 에너지 성능개선 전략수립을 목적으로 한 GEM-21P와 Carbon Navigator를 조사대상 평가프로그램으로 선정한 후, 두 프로그램에 대해서$LCCO_2$ 산출방법과 시스템의 구조에 대한 비교분석을 실시하였으며, 이를 바탕으로 계획단계에서 건축물의 전 생애 환경부하를 평가할 수 있는 시스템구축의 필요요소를 제안하였다.

Recently, there are growing interests in building LCCO₂ Assessment to reduce carbon emissions. However, existing methods of assessment system include inefficiency in the process of CO₂ calculation requiring considerable data input. Therefore, the purpose of this study is to develop an efficient building assessment system appropriate to material production in construction stage. To that end, quantity input technology was limited to data mapping. Also quantity calculation based on work breakdown structure and item codes consisted of hierarchical structure that is based on facet classification were analyzed. As a result, connectivity links of quantity calculation and CO₂ functional units through item codes for data mapping, and assessment system including calculation and database parts were developed.

BIM and its quantity take-off widely apply to the construction projects and LCCO2 Assessment using the BIM's quantity take-off function can be tried recently. Because BIM modeling programs such as Revit and ArchiCAD do not provide adequate library for LCCO2 Assessment, quantity take-off data should be conversed and applied to Carbon Emission Coefficient using Excel program or manual work. Therefore, the purpose of this research is 1) to propose the Unit Conversion Systems for Carbon Emission Coefficient, 2) to provide basic library sets for BIM based LCCO2 Assessment method, and 3) to apply 11 material library sets on a apartment unit plan modeling to pursue the CO2 emission evaluation of the material production in the process of LCCO2 Assessment. Research results showed CO2 emission amount of 458.64kgCO2/m2 from the apartment unit plan modeling.

In October 2009, the Ministry of Land Transport and Maritime Affairs noticed 'Environment-friendly housing construction standards and performance' to build energy saving environment-friendly housings (Green Homes) for the reduction of energy consumption and carbon dioxide emission. In this study, the $CO_2$ emissions were evaluated during the life cycle of the existing apartments which were built in 1980's and Green Home apartment. $LCCO_2$ was evaluated by dividing the life cycle into three stages which are construction, maintenance and destruction stage. $CO_2$ emission from the materials for improving insulation performance was estimated by Input-output analysis. As a result, in 40 year-life cycle of $84\;m^2$ apartment, 400.68 T-$CO_2$ was emitted from 1980's apartment, on the other hand 231.02 T-$CO_2$ was emitted from Green Home apartment.

Recently, there are growing interests on carbon emissions related in climate change which is worldwide emerging important issue. Some research works are now carrying out in order to reduce the carbon emission in pulp and paper industries by the synthesis of precipitated calcium carbonate using the exhaust carbon dioxide from combustion furnace or incinerator. However, for solving the original problems on carbon emission, we need to consider the analysis of basic methodology on $CO_2$ through the process efficiencies. There are two general tools for carbon emissions; one is the greenhouse gas inventory and the other is $LCCO_2$ method which is applied to particular items of raw materials and utilities in unit process. In this study, the carbon emissions in wood-containing printing paper production line were calculated by using $LCCO_2$ method. The general materials and utilities for paper production, such as fibrous materials, chemical additives, electric power, steam, and industrial water were analyzed. As the results, $Na_2SiO_3$ showed the highest loads in carbon emissions, and the total amount of carbon emissions was the highest in electricity. In the production line of printing paper using de-inked pulp and BTMP, as the mixing ratio of DIP was higher, the carbon emissions were decreased because of high use of electric power in TMP process.

The report of the intergovernment panel on climate change(IPCC) concluded that the global warning due to Green-house Gas(GHGs) will be accelerated in the 21th century. The railroad construction sector consumes a great deal of natural resources and energy in construction. maintenance, and demolition stage. In order to establish and perform reducing plan of GHGs of railway track system for effective corresponding the Climate Change Agreement, the evaluation method of the lifecycle CO2 emission if needed. In this research, it was investigates that the research trend for the LCCO2 and the method to estimate the lifecycle carbon dioxide emission amount of the railway track system as quantitative.

우리나라의 건축물은 국가에너지 소비의 상당한 비중을 차지하면서도 산업 및 교통분야에서처럼 효율적인 에너지 절약이 이루어지지 않는 문제점을 지니고 있다. 이처럼 건축물에 대한 에너지 절약이 잘 이루어지지 않는 가장 근본적인 원인은 건축물의 라이프 사이클이 다른 분야에 비해 매우 길고, 건축 각 분야들이 이해관계가 서로 다른 이질적 집단에 의해 이루어지기 때문이다. 즉 시공자, 건축주, 사용자 및 폐기업자 등이 개개의 운영비 절감을 위해서만 관심을 가질 뿐 건물의 Life Cycle에 대한 에너지, 환경부하 절감에는 크게 관심을 두지 않기 때문이다.(중략)

This study was suggested to develop sustainable durability design system and proposed the plan to evaluate design conditions that meet the intended service life and $LCCO_{2}$ reduction level of reinforced concrete structure easily from the early design stage. For that the W/B and covering depth of the concrete structure were calculated through calculation of service life based on standard specification expression and the quantitative reduction rate of the vertical member of reinforced concrete structure by the calculated W/B was applied. Life cycle of building classified into construction stage, operation stage, maintenance stage, and demolition/disposal stage and the method of $CO_{2}$ evaluation of each stage was proposed. For construction stage, the major construction materials that take up over 80% $CO_{2}$ emitting during building construction were selected and the $CO_{2}$ evaluation method for 5 standard apartment houses was proposed. Also, for operation stage, $CO_{2}$ emission was calculated through calculation of heating load by energy efficiency rating certification system. For maintenance stage, $CO_{2}$ emission was calculated using concept of re-construction by life and for demolition/disposal stage was calculated with the use of construction standard estimate. As a result of the case study by such evaluation methods, 80 years of service life and 17 specifications of sustainable durability design that meet the 40% intended $LCCO_{2}$ reduction level were deduced. The Maximum $LCCO_{2}$ reduction rate was analyzed by 47.2%.
