본 연구는 건축물 중 공동주택 단지를 대상으로, 건축물에 투입되는 자재생산부터 건축물이 해체되는 전과정동안 환경에 미치는 영향을 6개의 환경영향 범주로 구분하여 정량적으로 산출하였으며, 국내의 모든 산업이 환경에 미치는 영향을 대략적으로 분석하여 비교 평가하였다. 총 27 단지에 대한 환경영향을 분석한 결과 단지를 구성하는 건물 및 시설별로는 공동주택 건물이 단지 전체 대비 약 88.2%를 차지하는 것으로 분석되었으며, 이후 지하주차장, 공통부분, 복지시설, 판매시설, 기타시설 순으로 환경에 미치는 영향이 큰 것으로 분석되었다. 이중 가장 영향이 큰 공동주택 건물만을 대상으로 분석한 경우에는 전과정 중 사용단계에서 환경에 미치는 영향이 가장 크게 나타났으며 이후 자재생산단계, 시공단계, 해체 및 폐기단계 순으로 환경에 미치는 영향이 크게 분석되었다. 또한 공동주택 건물의 전과정에 대한 환경영향 분석 결과 국내 총 산업 대비 약 11. 96%를 차지하는 것으로 분석되었다. This study on condominium complex will adopt the quantitative assessment of the influence on the environment throughout the entire life cycle of buildings. This paper applies input-out analysis in order to analyse embodied energy regarding input of materials at material production phase. Also, it calculates environment load at use and demolition and destruction Phases of buildings as analysing energy consumption. The study categorises environment load as six impact categories and undertakes environmental impact evaluation. The consequence shows that the environment load of multi-unit dwelling takes up 88.2% out of the entire environment load of condominium complex. Also, as a result of analyzing the environmental impact of the life cycle of condominium buildings, it was found that such environmental impact comprised of about 11.96% of all industries in Korea that had an environmental impact.

In this study, the Simplified LCA technique is proposed as a way to quantitatively assess the potential environmental impact of the materials used in the construction of apartments is proposed. Then the analysis of cases is conducted to verify the reliability of the proposed simplified LCA technique using the data obtained from apartment constructions sites. With all data obtained from 27 apartment construction work sites, the full scale LCA for environmental impact assessment of all construction materials is conducted. The simplified LCA technique is also conducted by classifying the materials into the main materials which have big change in basic unit and other materials which do not. The error between the results of full scale LCA and simplified LCA was found to be 3.6% maximum. This result shows that the reliability of the proposed simplified LCA technique is good as a tool for conducting the environmental impact assessment over the life cycle of buildings.

This study comparatively analyzed the environmental impact of construction input materials on residential-commercial and apartment buildings to assess their environmental impact on residential buildings. In terms of analysis on construction statements for residential-commercial and apartment buildings, the energy consumption of construction input materials was estimated through input-output table assesment, and then their environmental impact was assessed. The study results found that in residential-commercial buildings, civil engineering was the highest with 38.5%, followed by construction (33.1%), landscape architecture (13.8%), machine (8.7%) and electricity & communication (5.9%) in terms of environmental impact. In addition, total environmental impact by unit area (/㎡) in residential-commercial buildings was 9.67E-02pe․yr/㎡, about 2.7 times higher than apartment buildings (3.57E-02pe․yr/㎡). 본 연구는 국내 대표 주거건물에 대한 환경영향을 평가하기 위해 주상복합 건물 및 아파트 건물에 대한 투입자재의 환경영향을 비교․분석하였다. 주상복합 건물 및 아파트 건물의 공사내역서 분석을 산업연관분석하여 투입자재에 대한 에너지소비량을 산출, 환경영향을 평가하였다. 주상복합 건물에 대한 공종별 환경영향 분석 결과 토목공사(38.5%), 건축공사(33.1%), 조경공사(13.8%), 기계공사(8.7%), 전기‧통신공사(5.9%) 순으로 환경영향이 높은 것으로 나타났으며, 주상복합 건물에서의 단위면적당(/㎡) 총 환경영향은 9.67E-02pe․yr/㎡로 아파트 건물의 3.57E-02pe․yr/㎡에 비해 약 2.7배 높은 것으로 평가되었다.

Purpose: The current study uses energy information made public as a part of building energy information access policy in order to analyze the pattern of end-use gas energy consumption in buildings and establish the basic unit of gas energy consumption by building use. Method: Monthly gas energy consumption data from buildings in various addresses, provided by the Korean government, was used in the current study. The data was categorized based on the similarity to each other, using cluster analysis method that can categorize large volumes of data with relative ease and speed. In cluster analysis, hierarchical clustering technique based on dynamic time warping was used, as it enables time series data analysis. Result: A cluster analysis of gas energy consumption in 291 buildings in greater Seoul area with 10 different detailed end-use purposes yielded 25 clusters: 76 buildings were in Cluster-1, 142 in Cluster-2, and 36 in Cluster-3, forming the bulk of the sample. Establishing the EUI of gas energy consumption by building use, the results showed that commercial-residential buildings had the highest consumption at 10.096kWh/㎡, followed by preschools, apartments, offices, religious facilities, stores, elementary schools, middle schools, and high schools using most energy, in that order.

In this study, a study was conducted to identify problems with the 'building LCA' evaluation items in a domestic green building certification system(G-SEED), and to prepare improvement plans. To this end, domestic and foreign green building certification systems were compared, and the evaluation items of G-SEED were analyzed and LCA case studies were conducted for Business facilities buildings, and the results were analyzed. As a result of the case analysis, it was analyzed that each environmental load impact category affects the environment in the order of 48.5% global warming, 37.3% resource depletion, 5.8% photochemical oxide production, 4.7% human toxicity, 2.0% acidification, 1.1% eutrophication, 0.4% ecotoxicity, and 0.3% ozone layer destruction. In addition, improvement plans were presented through the results of case analysis.

This study has analyzed the LCA of apartment complex to quantitatively evaluate the environmental impact of materials used for material production stage in the entire cycle. This study has also presented methods to simplify environmental impact evaluation on apartment complex by selecting major materials. The research findings on the environmental impact of 27 units of apartment complex are as follows. Sales facilities of per unit area (/㎡), which constitutes the complex had the biggest impact of 5.41E-02pe·yr, followed by other facilities (5.07E-02pe·yr), welfare facilities (3.51E-02pe·yr), underground parking lot (3.37E-02pe·yr), apartment buildings (3.11E-02pe·yr), and common areas (6.05E-03pe·yr). Meanwhile, major materials were selected as follows: 15 types of apartment buildings; 5 types of underground parking lots, welfare facilities, and sales facilities; 5 types of other facilities; 26 types of common areas.
