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

Cho, Chung-Suk,Chen, Don,Woo, Sungkwon Korean Institute of Building Information Modeling 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 Integrated Vegetation Systems into the New Sainsbury's Building Based on BIM

Lee, Dong-Kyu Korean Institute of Building Information Modeling 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 $Autodesk^{(R)}$ $Revit^{(R)}$ and this model was then simulated in $Autodesk^{(R)}$ $Ecotect^{(R)}$once weather data of the construction site was obtained from $Autodesk^{(R)}$ Green Building $Studio^{(R)}$. 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.

This study analyzed the difference of price determinants between the small-sized building and the medium-sized building among the small and medium commercial buildings. For this purpose, the reasonable Floor Area standard for dividing small and medium buildings was obtained through Chow-Test. Next, we compared and analyzed the price determinants estimated in the small buildings against the medium buildings. As a result, it is considered that physical management is important, as the relative Floor Area Ratio (FAR regulation / FAR observed) has a positive effect and U-shaped inflection is present in the building age effect. In terms of building use, medium-sized buildings were insignificant in their use, while small buildings were insensitive to building use. Therefore, small buildings need to be selected for tenants and image management as a single use. In addition, we found that the price index of small and medium buildings is different, and we need to be careful when we tie them together to read the price trend and make decisions. 본 연구는 중소형 상업용 빌딩을 대상으로 소형빌딩과 중형빌딩의 가격결정요인 사 이에 어떠한 차이가 존재하는지 분석하였다. 이를 위해 먼저 소형빌딩과 중형빌딩 을 나눌 수 있는 합리적인 연면적 기준(약1,200평)을 Chow-Test 를 통해 얻어냈 다. 다음으로 중형빌딩에 대비하여 소형빌딩에서 나타나는 가격결정요인을 비교분 석 하였다. 분석결과, 중소형 빌딩 공통적으로 상대용적률(법정용적률 / 현황용적률) 이 양(+)의 영향을 미치고 건물연령 효과에 U자형의 변곡이 존재하는 등 물리적인 관리가 중요한 것으로 판단된다. 건축물용도에 있어서는 중형빌딩이 용도별 차이가 유의하지 못했던 반면 소형빌딩은 건축물용도 차이에 민감한 것으로 추정되었다. 이에 소형빌딩은 임차인 업종의 선정, 단일 용도로서의 이미지 관리 등이 필요할 것 으로 판단된다. 추가로 소형빌딩과 중형빌딩의 가격지수가 차별화된다는 사실을 발 견할 수 있었으며 이 둘을 함께 묶어서 가격 흐름을 파악하고 의사결정을 내릴 때 에는 주의가 필요하다.

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.

건축법상 건축허가의 의미와 완공된 건축물에 대한 허가취소의 문제점

정훈(Jeong Hoon) 한국국가법학회 2021 국가법연구 Vol.17 No.1

Building Act Article 79 (1) provides that Where a building site or a building violates this Act, or an order or a disposition issued under this Act, a permitting authority may revoke the relevant permission or approval granted under this Act, issue an order to the project owner, contractor, site manager, owner, manager, or occupant of the building (hereinafter referred to as “project owner, etc.”) to suspend construction works, or demolish, alter, extend, repair, change the use of, prohibit or restrict the use of, the building, or take other necessary measures within a reasonable period set by the permitting authority. However independently of interests in litigation on litigation law, it requires a consideration that the revoking building permission for the building completed the construction is appropriate in view of a principle of permission law, and is meaningful in substance. But, the building permission does not also include maintenance and use of building completed, but only constructing of building. Building permission expires when construction of the building is completed, because the goal of building is achieved. Furthermore, according to「Building Act」Article 79, Article 80, the revoking building permission is not the requirement of the demolishing order, etc. or the imposing of charge for compelling compliance. And revoking building permission is not necessary for stable execution or efficiency of acministration as well. After completing the construction of the building, revoking building permission is for maintaining of legal building. But revoking building permission is not appropriate in view of a principle of permission law. Therefore this provision needs to revise.

The commercial facility is one of the important amenity facilities in office building. Recently, office building owners and managers are eager to enhance income stream from their commercial facilities by strengthening shopping and restaurant tenants. Since the retail potential commercial facilities in office buildings are influenced by the office building characteristics, trade area characteristics around office building, and so on, management strategies of commercial facilities could be different from office building to office building. Despite of these changes, there is little research on commercial facility in academic society. For these reasons, this study aims to examine the rent determinants of retail stores in commercial facilities. This study categorizes influencing factors into character of the office building, trade area, management, individual store. For empirical research, we analyze the rents of 393 retail stores at 38 commercial facilities of office buildings in Seoul. This study uses the hierarchical linear model to consider the effects of hierarchical influencing factors on rents including both office building level and individual store level. The results of the empirical analysis are as follows. Firstly, this study confirms office building characteristics including gross leasable area and building owner type, have considerable influence on store rents in the commercial facility. Secondly, this study finds trade area characteristics such as distance to subway station, road width, and pedestrian traffics around office building, have significant effects on store rents. Thirdly, this study discovers management characteristics such as the number of floors the commercial facilities occupy and management decision to operate commercial facility as an independent shopping mall, affect store rents in the commercial facility. Finally, this study shows the individual store characteristics such as store size, floor level that the store locates, whether the store has access to main pedestrian movement in the commercial facility, whether the store has signage outside of office building, and categories of tenant business, significantly influence on store rents.
