Regarding to the cadastral information and building information as a spatial information, studies on linking between cadastral records and building information, or integration methodology on 2D based building map and land information were proposed. Cadastral information has grown its values by cadastral resurvey project and cadastral confirmation survey. There is a tendency of BIM in the design stage which is not just simple 3D dataset and BIM is spreading in public and private sectors. However, studies on the linkage between building information and cadastral information is relatively weak comparing to the BIM spreading. One of the main features that have been improved in IFC4 is the interoperability with GIS. In this regards, the researcher propose several revision methods to link cadastral information to building information. Cadastral information needs to improve the quality of the dataset's such as unifying the different coordinate systems and preparing continuous cadastral map. For buildings, standardization of BIM in the public and private sectors is urgent task. IFC4 and upcoming IFC5 are international standards which need to be considered and BIM reverse engineering for the existing buildings is necessary for the public utilization in the near future.

The purpose of this study is to provide guidelines and recommendations on the process of planning and designing library space and it also reflects on developments which should be considered when planning new library space. The methodology of estimating library space needs of IFLA, a guide for public library building in New South Wales of Australia, and the recommendations for academic libraries in French were analysed. The results given throughout theses guidelines and recommendations are able to develop the guide for public library space in Korea. The guide suggested defines six broad types of library space; collection area, readers and library users, library staff, conference, meeting and cultural space, mechanical and support services, additional services areas. It is import to remember however that each library building and the service it provides is unique and should reflect the needs and aspiration of its community.

The interoperability of multi-source data has become more important due to various digital maps, produced from public institutions and enterprises. In this study, the automatic matching algorithm of multi-source building data using hierarchical matching was proposed. At first, we divide digital maps into blocks and perform the primary geometric registration of buildings with the ICP algorithm. Then, corresponding building pairs were determined by evaluating the similarity of overlap area, and the matching threshold value of similarity was automatically derived by the Otsu binary thresholding. After the first matching, we extracted error matching candidates buildings which are similar with threshold value to conduct the secondary ICP matching and to make a matching decision using turning angle function analysis. For the evaluation, the proposed method was applied to representative public digital maps, road name address map and digital topographic map 2.0. As a result, the F measures of matching and non-matching buildings increased by 2% and 17%, respectively. Therefore, the proposed method is efficient for the matching of building polygons from multi-source digital maps.

현대인의 경우 대부분이 하루 중 80% 이상의 시간을 어떤 형태의 가정, 사무실, 공공건물, 학교, 병원, 지하시설물, 상가, 음식점, 자동차, 지하철 등의 실내공간에서 생활하고 있으며, 특히 어린이와 노약자, 병약자들의 경우 대부분의 시간을 실내에서 보내고 있는 실정에 있어 실내공기오염이 인체에 미치는 영향은 크다고 할 수 있다. 실내환경에는 대기환경과는 달리 물리적, 화학적, 생물학적으로 매우 다양한 오염물질들은 복합적인 배출원에서 기인되며 그 배출량은 물질에 따라 상당히 편차가 있을 뿐 아니라 오염물질 농도분포 역시 시간적, 공간적 특성에 따라 다양하게 나타날 수 있으며, 실내공기의 상태는 일차적으로 외부공기의 영향을 받게 되고 이차적으로는 담배연기, 스토브, 오븐, 시멘트, 건축자재, 페인트 및 벽면의 입자상 물질 등과 같은 실내오염원으로부터 영향을 받아 오염상태가 심해진다.

실내 측위 시스템은 실내 환경에서 위치 기반 서비스를 하는데 매우 유용하다. 그러나, Wi-fi 신호 등을 사용하는 일반적인 실내 측위 시스템들은 대부분 시스템의 설치와 유지 보수에 많은 비용이 소요된다. 마커를 기준으로 측위를 하는 영상 기반의 시스템도 있지만, 일반 사용자들에게 미적인 문제를 야기 시킬 수도 있다. 이 논문에서, 우리는 대부분의 공공장소에 이미 설치되어 있는 간판 등을 이용하는 새로운 영상 기반의 실내 측위 시스템을 소개한다. 간판의 위치와 방향은 그것들이 설치 될 때 해당 건물의 기준 좌표계에서 위치와 방향이 결정되기 때문에, 간판에 대한 사용자의 상대적인 위치와 방향을 얻어내면 건물의 기준 좌표계에서 사용자의 위치와 방향을 구할 수 있다. 실제 공공장소에서 수행 된 실험은 우리의 시스템이 실내 측위의 실용적인 방법이 될 수 있음을 보여준다.

최근 공공건물, 중대형 건물 등에서 전력 피크 시간대에 또는 안정적인 전력공급을 위해 사용할 에너지를 저장하는 방법으로 ESS 를 채택하고 있다. 그러나 대부분의 ESS 의 상태를 모니터링하기 위해서는 별도의 PC 에 소프트웨어를 설치하거나, EMS(Energy Management System)와 같은 별도의 솔루션의 한 기능으로 확인할 수 있다. 이럴 경우, 소프트웨어가 설치되어 있지 않은 현장에서 확인이 어렵고, 자연방전이 일어난 경우 과방전의 가능성도 배제할 수 없다. 따라서 ESS 의 랙 내부에 LCD 화면을 탑재하여 ESS 독립적으로도 상태를 확인할 수 있도록 모니터링 시스템을 개발하였다. 본 연구의 ESS 모니터링 시스템은 ESS 의 안전성올 높이고, 보다 직관적으로 ESS 의 상태를 확인할 수 있도록 구현 하였다.

The Ministry of Land, Infrastructure, and Transport has been promoting strengthening energy efficiency of old buildings through public green building remodeling projects since 2020. Green remodeling includes both essential and optional construction of passive and active elements. However, there is a lack of integrated designs of passive and active systems and no standards for prioritizing these systems according to the building's age. Therefore, this study examined six public libraries in central region 2 that were expected to be high energy consuming. Remodeling strategy priorities were selected based on potential energy reduction. The libraries were divided into three groups based on their year of construction, completed in the 1980s (Model 1), 1990s (Model 2), and 2000s (Model 3). ECO2-OD, based on ISO 13790 and DINV 18599, was used as the primary energy consumption analysis tool. Simulation results indicated Model 1 and Model 2 benefited most from higher insulation and replacement of mechanical equipment. Model 3 benefited most from upgrading to more energy efficient windows.
