1. CONTENTS (1) RESEARCH OBJECTIVES The purpose of this study is to analyze the current status and practices of building management, and to find out through a survey with the people in building and property businesses how they recognize the necessity of property management, in order to find a new way of specializing the property management for office buildings. (2) RESEARCH METHOD In order to achieve the purpose of this study, we first examined the earlier studies and literatures related to building management. Second, we analyzed the results of the survey we carried out with 322 people in the building management and property businesses located in Seoul and smaller cities (Yongin, Ansan, Cheonan). (3) RESEARCH FINDINGS The finding of our study is summarized as follows: First, the property management market for buildings shows a steady growth since the financial crisis in late 1990's. However, the majority of these asset management companies remain small, providing mostly FM services, i,e. cleaning, guarding, landscaping, etc. Second, most building managers find it necessary to gain profession knowledge and receive re-education on property management on a continual basis. Third, they generally agree that the current license system for property management is not as efficient as it is supposed to be, and therefore it would be necessary to develop a new certification system. 2. RESULTS We suggest the following methods to specialize the property management for buildings. First, it is necessary to redefine the concept of property management of building. Second, it is necessary to introduce a government certification system for 'property management of building' and to put the existing institutes of training experts for property management of real estate under the government system. Third, it is necessary to introduce a registration system for building-property management companies and to make it imperative for any building more than certain scale to assign building management to a specialist of property management of building so that this can vitalize the buildings-property management market.

DongKyu Lee 한국BIM학회 2014 KIBIM Magazine Vol.4 No.2

Today, there is a growing need of environment-friendly buildings, so-called ‘green’, facilities, and energy saving buildings to decrease environmental pollutants released into cities by construction activities. Green-Building Information Modeling (Green-BIM) is a purpose-built solution which supports to forecast energy consumption of 3-D model of a building by augmenting its primary 3-D measurements (width, height and depth) with many more dimensions (e.g. time, costs, social impacts and environmental consequences) throughout a series of sequential phases in the lifecycle of a building. The current study was carried out in order to integrate vegetation systems (particularly green roof and green wall systems) and investigate thermal performance of the new Sainsbury’s building which will be built on Melton road, Leicester, United Kingdom. Within this scope, a 3-D building model of the news Sainsbury’s building was first developed in Autodesk?? Revit?? and this model was then simulated in Autodesk?? Ecotect??once weather data of the construction site was obtained from Autodesk?? Green Building Studio??. This study primarily analyzed data from (1) solar radiation, (2) heat gains and losses, and (3) heating and cooling loads simulation to evaluate thermal performance of the building integrated with vegetation system or conventionally available envelops. The results showed that building integrated vegetation system can potentially reduce internal solar gains on the building rooftops by creating a ‘bioshade’. Heat gains and losses through roofs and walls were markedly diminished by offering greater insulation on the building. Annual energy loads for heating and cooling were significantly reduced by vegetation more significantly through the green roof system in comparison to green wall system.

Simultaneously, in order to solve a global environmental matter and an energy issue, the application of the renewable energy in the building has been constantly demanded. therefore, we must develop new energy resources which are abundant and substitute for fossil fuels. we must study the application method of the renewable energy in the building. Among renewable energy, the solar energy(photovoltaic system) is clean, inexhaustible and available everywhere around the world. Photovoltaic system has the application possibility in the building. the BIPV(Building Integrated Photovoltaic) system is the integration of photovoltaic into the building envelope, such as the roof or the facade. the use of BIPV system is a new design method in architecture. the aim of this study is to analyze the application possibility of BIPV system in the office building. therefore, we investigated electric power loads and exterior design of office building in the daegu metropolis and judged the integration capability to the office building of BIPV system.

BUILDING INFORMATION MODELING (BIM)-BASED DESIGN OF ENERGY EFFICIENT BUILDINGS

ChungSuk Cho,Don Chen,Sungkwon Woo 한국BIM학회 2012 KIBIM Magazine Vol.2 No.1

With the increased awareness of energy consumption as well as the environmental impact of building operations, architects, designers and planners are required to place more consideration on sustainability and energy performance of the building. To ensure most of those considerations are reflected in the building performance, critical design decisions should be made by key stakeholders early during the design development stage. The application of BIM during building energy simulations has profoundly improved the energy analysis process and thus this approach has gained momentum. However, despite rapid advances in BIM-based processes, the question still remains how ordinary building stakeholders can perform energy performance analysis, which has previously been conducted predominantly by professionals, to maximize energy efficient building performance. To address this issue, we identified two leading building performance analysis software programs, Energy Plus and IES <Virtual Environment> (IES <VE>), and compared their effectiveness and suitability as BIM-based energy simulation tools. To facilitate this study, we examined a case study on Building Performance Model (BPM) of a single story building with one door, multiple windows on each wall, a slab and a roof. We focused particularly on building energy performance by differing building orientation and window sizes and compared how effectively these two software programs analyzed the performance. We also looked at typical decision-making processes implementing building energy simulation program during the early design stages in the U.S. Finally, conclusions were drawn as to how to conduct BIM-based building energy performance evaluations more efficiently. Suggestions for further avenues of research are also made.

Building wind refers to strong winds or circulating airflows formed around buildings by arrangement and shape of buildings. Building winds occur around most buildings, especially high-rise buildings. Today, risk of building winds is increasing due to high-rise and high-density cities. When designing a high-rise building, it is necessary to evaluate influence of building wind by building and take measures to reduce building wind. However, in Korea, social awareness of building wind is lacking, and there are insufficient measures for wind environment evaluation criteria and building wind environmental impact assessment. Therefore, in this study, wind speed and direction of target area were evaluated through field surveys of building winds observed in pedestrian walkways near high-rise buildings.

Building change monitoring based on building detection is one of the most important fields in terms of monitoring artificial structures using high-resolution multi-temporal images such as CAS500- 1 and 2, which are scheduled to be launched. However, not only the various shapes and sizes of buildings located on the surface of the Earth, but also the shadows or trees around them make it difficult to detect the buildings accurately. Also, a large number of misdetection are caused by relief displacement according to the azimuth and elevation angles of the platform. In this study, object-based building detection was performed using the azimuth angle of the Sun and the corresponding main direction of shadows to improve the results of building change detection. After that, the platform’s azimuth and elevation angles were used to detect changed buildings. The object-based segmentation was performed on a highresolution imagery, and then shadow objects were classified through the shadow intensity, and feature information such as rectangular fit, Gray-Level Co-occurrence Matrix (GLCM) homogeneity and area of each object were calculated for building candidate detection. Then, the final buildings were detected using the direction and distance relationship between the center of building candidate object and its shadow according to the azimuth angle of the Sun. A total of three methods were proposed for the building change detection between building objects detected in each image: simple overlay between objects, comparison of the object sizes according to the elevation angle of the platform, and consideration of direction between objects according to the azimuth angle of the platform. In this study, residential area was selected as study area using high-resolution imagery acquired from KOMPSAT-3 and Unmanned Aerial Vehicle (UAV). Experimental results have shown that F1-scores of building detection results detected using feature information were 0.488 and 0.696 respectively in KOMPSAT-3 image and UAV image, whereas F1-scores of building detection results considering shadows were 0.876 and 0.867, respectively, indicating that the accuracy of building detection method considering shadows is higher. Also among the three proposed building change detection methods, the F1-score of the consideration of direction between objects according to the azimuth angles was the highest at 0.891. 건물탐지 기반의 건물 변화 모니터링은 발사예정인 차세대 중형위성 1, 2호와 같은 고해상도 다시기 광학 위성영상을 이용한 인공 구조물 모니터링 측면에서 가장 중요한 분야 중 하나이다. 하지만 지표면에 위치하는 건물들의 형태와 크기는 다양하며, 이들 주변에 존재하는 그림자 또는 나무 등에 의해 정확한 건물탐지에 어려움이 따른다. 또한, 영상 촬영 당시의 플랫폼의 방위각(Azimuth angle)과 고도각(Elevation angle)에 따라 생기는기복 변위로 인해 건물 변화탐지 수행 시 다수의 변화 오탐지가 발생하게 된다. 이에 본 연구에서는 건물 변화탐지 결과 향상을 위해 다시기 영상 취득 당시의 태양의 방위각과 그에 따른 그림자의 주방향(Main direction)을이용한 객체기반 건물탐지를 수행하였으며, 이후 플랫폼의 방위각과 고도각을 이용한 건물 변화탐지를 수행하였다. 고해상도 영상에 객체 분할 기법을 적용한 후, Shadow intensity를 통해 그림자 객체만을 분류하였으며, 건물 후보군 탐지를 위해 각 객체의 Rectangular fit, GLCM(Gray-Level Co-occurrence Matrix) homogeneity 그리고 면적(Area)과 같은 특징(Feature) 정보들을 이용하였다. 그 후, 건물 후보군으로 탐지된 객체들의 중심과 태양의 방위각에 따른 건물 그림자 사이의 방향과 거리를 이용하여 최종 건물을 탐지하였다. 각 영상에서 탐지된 건물 객체 간 변화탐지를 위해 객체들 간의 단순 중첩, 플랫폼의 고도각에 따른 객체의 크기 비교, 그리고플랫폼의 방위각에 따른 객체 간의 방향 비교 총 3가지의 방법을 제안하였다. 본 연구에서는 주거 밀집 지역을연구지역으로 선정하였으며, KOMPSAT-3와 무인항공기(Unmanned Aerial Vehicle, UAV)의 이종 센서에서 취득된 고해상도 영상을 이용하여 실험 데이터를 생성하였다. 실험 결과, 특징 정보를 이용해 탐지한 건물탐지결과의 F1-score는 KOMPSAT-3 영상과 무인항공기 영상에서 각각 0.488 그리고 0.696인 반면, 그림자를 고려한 건물탐지 결과의 F1-score는 0.876 그리고 0.867로 그림자를 고려한 건물탐지 기법의 정확도가 더 높은 것을확인할 수 있었다. 또한, 그림자를 이용한 건물탐지 결과를 바탕으로 제안한 3가지의 건물 변화탐지 제안기법중 플랫폼의 방위각에 따른 객체 간의 방향을 고려한 방법의 F1-score가 0.891로 가장 높은 정확도를 보이는 것을 확인할 수 있었다.

Domestic real estate asset management market has been changed during experiencing financial crisis. When the building which was purchased by foreign capital was been entrusting in global asset management company, the concept which managing for real estate asset was appeared. Depending on this situation, domestic real estate asset management companies which mainly manage own corporate building has begun to obtain management contract for large building management on external market. and this situation competition is becoming fierce. However this situation is equivalent to a large building. Because of building’s small scale, small and medium-sized buildings are lack of interested than large building in building management. Therefore, small and medium-sized building’s situation require efficient building management system. Thus on this study identified small and medium-sized building’s characteristics and problem, Analyze priority on real estate management of small and medium-sized building focused on building owner, management company and then deduce those several results. First, The most important item is ‘Tenant Management’ in small and medium-sized building management. Second, The ‘Space Image Management’ is turned up high importance relatively in the owner’s group and professional group. Third, ‘Legal, Tax Management’ item appeared lowest priority in the overall group. After all, ‘Tenant Management’, ‘Asset Investment Management’, ‘Space Image Management’ items will be considered significant to provide a high quality of real estate asset management service in the small and medium-sized building management.

The research of energy saving in building was studied many case of studies. The zero energy building contained a two concept like a minimum energy consumption and renewable energy facility installation for energy suppling. It means what the envelope of Zero Energy building has high performance of thermal. And the facility of building use independent heating and cooling energy consumption without outer source too. For accomplish the zero energy building, many technology were developed and applied at new building. In case of applying technology, the critical technology is enough for the zero energy building but the joint technology for zero energy building is not enough. Also the supply of the economical technology is difficult. To solving these difficult, the energy performance evaluation tool is used by many researchers in phase of the building design. These tool have a problem about reproducibility by the different input data. That was inputted by each simulator and they divided to level about expertise and situation. So they need to getting an specific information of building and advanced training of simulation. But for accomplish the zero energy building, these tool must be have modified to analysis of the building energy consumption suitably. Absolutely these tool need to update for the precision of analysis results. Additionally the zero energy building design contain a new technology for energy saving through the tool’s extendability. In this study, authors was proposed the technical package and the case of simulation tool was compared for improvement suggestion. And this study was based actual certification and analysis tools like a ECO2. By these result, the authors was proposed two the improvement suggestion ‘User friendly Interface’ and ‘Analysis reliability’.
