최근 유비쿼터스(ubiquitous), 네비게이션(navigation), 위치기반서비스(Location Based Service) 등의 발전으로 공간정보에 대한 욕구가 증가하고, 나아가 사용자의 환경에 구애받지 않고 공간정보를 제공하는 서비스가 발전하고 있다. 그러나 현재 우리나라는 표준화된 식별자가 없이 정부 부처별 또는 지방자치단체로 공간정보 특히, 그 필요성이 높은 건축물을 DB로 구축 관리하고 있어, 이들 시스템의 고유번호를 건축물 유일식별자로 활용하는데 한계가 있다. 또한 여러 지형지물 식별차도 개별 업무 및 DB관리를 위하여 부여된 측면이 있어 건축물 유일식별자로는 적당치 않았다. 따라서 본 연구에서는 국가 차원의 건축물 유일식별자의 필요성을 제기하고, 이들 유일식자 관리시스템을 난립한 건축물 고유번호를 상호적으로 변환하는 시스템으로 활용할 것을 제안한다.

The purpose of this research is to manage the physical sectors systematically, needed for the selection and direction of declining areas, such as urban regeneration and revitalization projects, by grading the density of decline indicators of buildings in small and medium cities. In five small and medium-sized cities in Jeollanam-do, the data were divided into three stages according to the density, according to the use, structure, and age of the building. Rating by element of Census Output Area, detailed designation, and management of declining areas in small and medium-sized cities are required, rather than setting the scope of declining areas based on administrative districts. It is also necessary to manage cities through complex and intra-element phasing rather than single elements in defining physical decline. The analysis based on the complex factors and boundary of the Census Output Area is meaningful in order to maintain and manage such cities in a more detailed and precise manner according to such characteristics of each region.

This research aims to examine the spatial patterns of vacant housings and the factors determining housing vacancy in Daegu using individual-level building DB. The results of the spatial pattern analysis showed a donut shaped-spatial concentration of vacant housings in the central areas of the city. The results of logistic regression analysis revealed that not only individual building characteristics, such as building area, number of floors, and building age, but also socio-economic characteristics of community, such as urban redevelopment district, number of adjacent vacancies, recent population change, and ratio of elderly, are important factors affecting housing vacancies.

Life of building repeats removal and new construction continuously because it is limited like living things. But, because the physical standard is subjective and abstract, saying too much is not even though it had been influenced by policy decision of the government. To solve these problem clear data about superannuation degree of building after construction accordingly decision relationship necessity continuously rise. To above background, this study on the Constructing Database Based and Improvement of Old Building using GIS in Busan. The results are as following. First, presented necessity of knowledge information gap mitigation. Second, present Busan's ordinance detailed Contents of old-badness building and production-consequences.

최근 건축물에서 공동주택의 비율이 증가하고 있으며 동시에 공동주택의 화재비율도 증가하는 경향을 보이고 있다. 또한 화재 시 인명 피해의 주원인인 가연물은 소재가 다양화되고 있으나 안정성 보다는 디자인, 기능성에 치중되어 그에 따른 화재 위험성도 커져가고 있다. 따라서 본 연구는 전보의 실내장식물에 이어 공동주택에서 많이 사용되어지는 적재가연물을 가연물 조사를 바탕으로 선정하여 Furniture Calorimeter를 이용해 그 연소특성을 알아보았다. 그 결과, 소파가 타 시료에 비해 화재 시 높은 위험성을 나타냈으며, 일본건축학회에 발표된 데이터와 비교한 결과 소파의 데이터가 유사한 것으로 나타났다.

Korea has a high volume of exhaust in environmental pollutants compared to her economic size, which results from the increase of the ratio in high energy consuming industries. There arises an issue that efficient energy saving is not achieved in the related projects of the construction, which is one of the high energy consuming industries. In addition, such projects of dismantling old and decrepit buildings are frequent in recent years. Given the situation, to obtain much better effects of energy saving, it is necessary to build basic databases and develop utilization plans on energy consumption volume, exhaust volume of pollutants, and environmental expenses that come from the dismantlement stages out of the life cycle of construction projects. Therefore, this study calculates the exhaust volume of environmental pollutants, converts it into environmental expenses by pollutants, and evaluates the environmental economics on the projects of dismantling buildings, utilizing LCI DB that is suggested by Ministry of Knowledge Economy and Ministry of Environment. For this purpose, related data research, the existing literature study, and on-the-spot field investigation were conducted. Based on the results of analysis on the collected data, the environmental economics of the target building was evaluated.

본 연구는 건축구조물의 내장재 및 실내장식물 등의 연소 성상 DB를 바탕으로 화재 성상을 예측할 수 있는 기존 모델인 칼슨모델(B.Karlsson) 및 퀸티어리모델(J.G.Quintiere)을 비교, 분석하여 그 절차 및 차이점 등을 분석한 후 국내 가연물 연소성상 DB를 토대로 개구조건 및 건물구조 등을 고려한 화재성상 시뮬레이터 개발을 위한 기초 조사 자료이다. 조사 결과 칼슨모델과 퀸티어리모델의 차이점은 우선 초기 착화영역과 착화의 판단 및 연소면적 등에서 차이가 있었으며 향후 이를 기초로 실험 결과와 대비를 통한 분석을 수행 할 예정이다.

기후변화로 인한 거대 자연재해 발생의 위험이 지속적으로 증가하고 있으며, 국외의 경우 주요정부기관, 보험사 및 연구기관 중심으로 자연재해 피해예측 모델을 개발하여 사용하고 있다. 침수사고 인한 피해는 건물은 물론이고 가재도구, 재고자산, 기계시설 등의 내용물에서도 발생하며, 건축물 신축단가 등을 이용해 비교적 쉽게 자산가치를 산정할 수 있는 건물구조물과 다르게, 건물내용물의 자산가치는 시설물의 업종, 용도, 사용자 특성 등에 따라 변동성이 큰 특징이 있다. 내용물의 피해액 추정을 위해 자연재해 피해예측 모델은 건물 구조물과 내용물 가치의 비율인 CSVR(Contents to Structure Value Ratio)을 사용하며, CSVR은 시설물 용도에 따른 자산가치평가 통계를 이용해 산정할 수 있다. 충분한 자산가치평가 DB를 확보할 경우 CSVR의 정확도 확보가 가능할 것이며, 이를 위해 국내에서는 민간보험사의 재물보험 계약 4만여건의 건물, 내용물 보험가입금액을 행정안전부 도로명전자지도에서 분류하는 건물 용도에 따라 분석한 연구결과가 있다. 하지만, 일반적으로 보험가입단계에서 대략적으로 추정하는 보험가입금액과 실제 자산의 가치는 차이가 있을 수 있지만, 보험가입물건의 실제 자산가치는 일부만 DB화 되어 있는 단점이 있다. 본 연구에서는 사고 발생 후 작성되는 손해사정보고서에서 평가한 정확한 자산가치 DB를 수집하여, 보험가입금액을 기준으로 산정한 CSVR의 결과와 비교하였다. 손해사정보고서에서 평가한 실제 자산가치를 기준으로 분석한 CSVR과 보험가입금액을 기준으로 산정한 CSVR은, 업종에 따라 유사하거나 큰 차이를 보이는 경우도 있었으며, 침수로 인한 정확한 피해액 추정을 위해서는 보다 양질의 DB확보를 통한 CSVR의 정확도 확보가 필요한 것으로 분석되었다.

In a construction project, the portion for maintenance costs for a building is considerable compared to the initial construction cost. As such, Life Cycle Cost (LCC) analysis is being increasingly utilized to assess the design value of engineering work in Korea. Additionally, the Public Procurement Service in Korea announced that it will be mandatory for all domestic construction projects to adopt BIM. Furthermore, the paradigm for architectural design has shifted from 2D to 3D, and to BIM, which includes a data management system. Within this background, however, there is currently no adequate BIM-based LCC analysis software and the requirements of cost estimation for repair and replacement cost for a building is not completely adequate in BIM tools such as Revit and Archicad. Therefore, this study suggests a process of cost estimation for repair and replacement (R&R) cost based on IFC data. First, we analyzed existing R&R criteria and defined BIM-based requirements when calculating R&R costs. These requirements were extracted from relevant IFC data. Subsequently, this was saved to a database and a BIM-based database was built for R&R cost estimation. Finally, this database was connected with external databases such as R&R Criteria DB and Cost Information DB to calculate R&R costs. This process is expected to improve upon the traditional process of cost estimation of R&R cost by applying a BIM model. The proposed process can contribute to a further standardizing of BIM-based LCC analysis thru application to initial construction costs, energy costs, and other maintenance costs.

The importance of LCC analysis has been enlarged. Also, it would be necessary to computerize LCC analysis for accurate and logical analysis of LCC. In other papers, they showed LCC analysis model but the study of database development which could be applied in LCC analysis have been undeveloped. As a result, the final goal of this study is to develope LCC database. And this progress is devided 4 steps as design, construction, maintenance and disposal and derived the detailed cost item in the progresses. Futhermore, it would be possible to develope cost DB, fluent DB, general DB, building section DB, material DB and to propose database which would be applied in accurate and logical analysis of LCC.
