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.

This study is intended to calculate the actual recycling ratio of construction waste generated on site of the final disposal company. It is also analyzed the construction waste of the final disposal company, as well as aiming to ultimately analyze the actual disposal state of Korea's construction waste. According to on-site research on the middle disposal company, the average recycling ratio, reclamation, and incineration of brought in waste were 95.6%, 4.2%, and 0.01%. As the result of on-site research on the middle disposal company, disposing ratio of construction waste was shown at 4.2% lower in recycling percentage when compared to statistic data of Ministry of Environment, Republic of Korea(year 2005, in metropolitan area) and 4.0% and 0.01% higher in reclamation and incineration compared to the data. These differences seem to be because export data of waste in simple construction fields were only applied in the process of the current statistic data calculation. Actual results of construction waste's final disposal company was not reflected. Therefore, in order to improve efficiency of the government's construction waste-related policy, it is judged there needs to be improvements in current disposal methods.

This study estimates the change of sunlight environment on the present relaxation movement of floor area ratio and provides the maximum upper limit of floor area ratio per arrangement pattern of the apartment houses, as a result obtained from the above estimation. The arrangement patterns had been classified into 4 cases by carrying out case analysis; Case 1: the parallel arrangement of plates, Case_2, 3: the mixture arrangement of plates and towers, Case_4: the parallel arrangement of towers. And the total 12 analysis patterns including the detail analysis pattern, which the variable factor was the rearrangement of a floor per case, had been defined. In the arrangement of Case_1, we analyzed that the application of more than 250% of floor area ratio, which value is the maximum permitted limit of floor area ratio on the present residential area, was impossible at all analysis patterns. In the arrangement of Case_2 and Case_3, we analyzed that the application of 350% of floor area ratio was possible at only two patterns; one is the pattern of increasing the number of the floors for a tower and the other is the pattern of arranging a plate and a tower on the same floor. In the arrangement of Case_4, we analyzed that the application of up to 400% of floor area ratio was possible at all patterns analyzed, with regardless of the change of the number of the floors.

This study attempted to estimate oil consumption and carbon dioxide emissions caused by the use of construction equipment and machine at the construction operation phase in 27 apartment construction sites. To calculate oil consumption at the construction operation phase of the apartment buildings, the construction equipment & machine-used construction items were classified using the construction statements. Then, oil consumption at the construction operation phase was obtained in 27 apartment construction sites. For carbon dioxide emissions, the construction items were categorized by construction type and building based on the estimated oil consumption. In terms of carbon dioxide emissions by building, ‘welfare facilities’ were the highest with 11,508.86g-CO₂/㎡(27%). In terms of carbon dioxide emission by construction type, on the contrary, ‘building construction’ was the largest with 5,453.25g-CO₂/㎡(89.34%).

This paper reviewed the validity of IRT from the comparison·analysis of U-value and HFM results of apartments in Korea, which have been calculated using IRT, and presents the evaluation solution for thermal insulation performance that can consider the main environmental factors. Side walls of 3 apartments that were constructed in 10-year intervals from one another, were selected as subjects of measurement. The subjects’ environmental impact of surroundings and measurement device’s errors were considered for analysis. In result, it is evaluated that there is validity of ±20% error between IRT and HFM measurement methods when reflected temperature is at ±1.0<SUP>o</SUP>C range of air temperature and emissivity is at ±0.2 range.
