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, targeting the residential-commercial building which is recently emerging as the representative residential facility of urban area, analyzed the characteristics of environmental impact of input materials making up a building using LCA method, and constructed LCI DB for input materials. As a result of the analysis of Complex 8 (31 buildings), the average environmental impact of the residential-commercial building was found to be 9.67E-02 pe·yr/m², being analyzed high in the order of civil (38.5%), architecture (33.1%), landscape (13.8%), mechanical (8.7%) and electric&telecommunication construction (5.9%). In addition, through the sensitivity analysis of the case buildings, this study selected major materials for 15 sorts of buildings, 3 sorts of civil construction, and 1 sort of landscape construction, and the average environmental impact of other materials excluding the selected major materials was analyzed as 2.48E-02pe·yr/m² for a building, and 2.61E-02pe·yr/m² for a site.

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.

In this study, the dry heat storage floor heating block for which heat storage capacity was improved for the sake of transforming the floor heating system into dry type was developed, and the thermal environment for this was evaluated. In order to evaluate the thermal environment, the change of temperature in accordance with the supply of hot water was analyzed by constituting two kinds of floor heating systems for which existing wet method and dry heat storage floor heating block presented in this study were applied, respectively. According to the analysis, up to the stabilization of floor surface temperature, 240 minutes were confirmed to be taken for wet method, and 320 minutes for dry heat storage floor heating block, and when comparing the temperature difference after the stabilization of floor surface temperature, dry heat storage floor heating block was analyzed to have around 3℃ lower temperature than wet method. On the other hand, in terms of maintaining the floor surface temperature based on the heat storage effect of structure after stopping the supply of hot water, the dry heat storage method was analyzed to be more advantageous compared to wet method.

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 study aims at proposing an optimal remodeling cycle in the light of economic feasibility consequent on the payback cycle of investment cost in energy performance improvement of a military barracks facing a maintenance cycle, and cost-saving effect. On the basis of the result of the preceding research which analyzed the energy requirement of a military barracks by the year of completion, this study analyzed the economic feasibility of a military barracks by selecting the energy remodelling plan, and cost analysis condition. The analysis result revealed that cost-benefits occurred after the elapse of 1.8 year to 7.5 years marking the regional payback cycle of investment cost in case of concurrent implementation of energy remodeling which serves to reinforce the heat insulation layer, and to improve window performance in doing repair work by part on a military barracks, which was built in the early 2000s, facing a maintenance cycle of roof waterproofing-finishing materials-window. On the contrary, in case of failure to do concurrent implementation of energy remodeling, it was analyzed that cost-benefits occurred after the elapse of 9.2 years to 20 years.

Recently, the military facilities have been enlarged due to the increase in floor area through continuous improvement projects. Therefore, in this study, a standard model was selected for the military barracks, a representative military facility, and the change in energy consumption according to the change in insulation standards was analyzed. The military barracks standard model required for energy consumption calculation was selected as the recently newly constructed 4-story model with reference to military facility standards. In addition, the insulation standards required for energy consumption calculation are applied to the annual insulation standards of military barracks. As a result of the analysis, the energy consumption in Chuncheon was the highest, and the energy consumption in Busan was the lowest. It was also analyzed that the average energy consumption decreased by 11% in the central region, 10% in the southern region, and 17% in Jeju compared to the insulation standard in 1987.

This study did quantitative comparative evaluation of changes in generation consequent on reflectivity of the protruding wall near the widow in case of application of PV window system to an apartment house. To be concrete, this study did comparative analysis of the generation of (B) through the process of composing Mock-up (A)comprising the protruding window near the window and Mock-up(B) free of nearby wall interference, and giving change to the reflectivity of the wall (Case_1~3). The analysis result showed that the difference in generation was slight in case solar radiation was less than 10,000Wh in all three conditions. On the contrary, in case solar radiation was more than 10,000 Wh, the generation as against Module(B), was analyzed to be 87~91% in Case_1(5% reflectivity), 18~60% in Case_2(85% reflectivity), and 16~71% in case_3(93% reflectivity), respectively.
