  • This study is to draw thermal property data during long-term aging, by testing the thermal conductivity of building insulation materials in Korea. The thermal resistance of extruded insulation within 3 days from manufacture performed well over the KS Standard. After 50 to 110 days, however, the thermal performance had deteriorated to the level of the KS standard. Eventually, after 4,000 days, the insulation performance had deteriorated to about 25.4~41.8% of the initial performance. Therefore, this research will be utilized as a reference for thermal properties during long-term aging, in order to improve standards and regulations related to building insulation materials.

  • The proposed building upgrading technique employs prestressing cables to function as bracing to improve the seismic performance during future events. A four-story reinforced concrete moment resisting frame damaged from an ultimate limit state earthquake is assessed and upgraded using the proposed technique. Both existing and upgraded buildings are evaluated in regard of seismic performance parameters performing static lateral load to collapse analysis and dynamic nonlinear time history analysis as well. To obtain realistic comparison of seismic performance between existing and upgraded frames, each frame is subjected to its critical ground motion that has strength demand exceeding the building strength supply. Furthermore, reliability of static lateral load to collapse analysis as a substitute to time history analysis is evaluated. The results reveal that the proposed upgrading technique improves the stiffness distribution compared to the ideal distribution that gives equal inter-story drift. As a result, the upgraded building retains more stories that contribute to energy dissipation. The overall behavior of upgraded building beyond yield is also enhanced due to the gradual change of building stiffness as the lateral load increases.

  • To lead lighting inside, design solution and mechenical solution can be used.A inner court and atrium are samples for design solution. However, physical and environmental elements for building design are not taken positively into consideration. So low position of the inner court is difficult to reach lighting performance and a urban landscape gets damaged. On this study, selecting a building with a inner court, best design method is suggested to apply reflecting mirror. building direction, building shape and solar position are considered to deside the setting angle for reflecting mirror. Performance for the setting reflecting mirror is verified through various simulation cases, and is got more lighting performance than the present situation on the building inside.

  • In this study, the control performance of a Tuned Liquid Mass Damper(TLMD) manufactured to reduce the orthogonal bi-directional responses of building structures was experimentally evaluated. the TLMD using only one control device reduce bi-directional responses of building structures by making the TLMD behave as TMD and TLCD to the strong and weak axial direction of building structures. first, the control performance was evaluated by forcing sinusoidal waves to a test model that the TLMD is installed on the scale-downed building structure. Second, the real-time hybrid shaking table test was performed to evaluate the performance of the vibration control system made up of numerical part as a scale-downed building structural model and a physical experimental part as a TLMD. the superiority of bi-directional vibration control performance of the manufactured TLMD was verified by comparing the uncontrolled and controlled results of these tests.

  • 건물의 소방설비시스템의 유지 관리 상태에 이상이 나타났다고 한다면, 특정 기능의 이상이 미치는 부분적 또는 전체적인 화재안전대응수준에 영향을 미친다. 따라서 효율적 소방성능을 유지하기 위해 설비기능의 가동상태를 나타 낼 수 있는 성능지수의 계산 체계가 필요하다. 이러한 성능지수의 체계는 정보수신자가 부분 이상으로 발생한 영향이 전체 기능의 상태에 얼마나 영향을 주는 것인지를 쉽게 인지할 수 있도록 하는 데에 기여할 수 있다. 따라서 건물의 화재안전수준을 나타내는 효율지표로 사용될 수 있을 뿐만 아니라, 광대역규모의 소방 관리에서도 활용성 높은 지수로 사용될 수 있다. 본 지수 산정체계는 U-건물 소방방화시설관리 운용시스템의 성능 효율지수 산정을 위한 시스템으로 개발되었다.

  • 건축물의 생애주기 전반에 걸쳐 중요한 영향을 줄 수 있는 건축물의 성능과 관련하여, 설계 초기단계에서 계획안의 환경성능을 검토할 수 있는 디자인 피드백의 중요성이 점차 부각되고 있다. 그런데, 건설산업 특성에 따른 전문분야 도메인 구분으로 인해, 서로 다른 어플리케이션 사이에서 데이터 호환성의 문제에 따른 제약이 많은 실정이다. 이에, 지식기반 디자인 방법론에 기반하여, 본 연구는 건축물의 형상과 연동 가능한 BIM 객체의 기하정보에 대한 상관관계 정보체계를 제안하도록 한다. 이를 위해, 오피스 건축물의 기획 및 계획설계 단계를 대상으로, 상용 BIM 시스템인 Autodesk Revit을 활용하여 매스 형상에 파라메트릭 제약조건을 설정한다. 나아가, 오피스 매스의 형상정보와 양방향 프로세스로 연동가능하도록, Autodek Green Building Studio 엔진에서 분석가능한 해석모델로 변환함으로써, 파라미터에 의한 형태 변형에 따른 다양한 대안들에 대하여 실내조도 성능을 시뮬레이션한다. 이를 통해, 디자인 조건들을 만족시켜주는 범위 내에서 적절한 환경성능의 검토가 가능한 정량적인 의사결정 방법을 제시하고자 한다.

  • In evaluating sound performance of building, it is important to carry on tests and evaluations based upon residential sound performances. Korean Standards include test methods on sound performance, but don't include any code on evaluation methods. Therefore, evaluation methods from Japan or ISO have been used for evaluating sound performance in domestic so far. In this study, a draft of Korean Standards on a sound performance evaluation method in buildings is proposed.

  • Global environmental problems are growing, and the importance of buildings with high energy consumption has been emphasized. In Korea, the Ministry of Land, Transport and Maritime Affairs has been promoting the mandatory zero energy building since 2020, and guidelines related to the zero energy building have been developed. In addition, based on the "Energy-saving Design Criteria for Buildings" of the "Green Building Promotion Act" in Korea, the standards for energy-saving design are specified and the energy saving plan is written. Besides, the 'Energy-saving construction standards for eco-friendly houses' also specify insulation, machinery, equipment, and sunshade. Also, there is little consideration about the cost such as construction cost and material cost which should be considered important in the construction stage. Therefore, this study aims at analysis of building type and energy performance versus materials for energy saving building design considering energy performance in planning aspect of initial design stage. In this study, because the variables can not be neglected in this study, it is selected as the lecture facility of the 'K' university campus building which can consider the remaining factors except the passive design element as the control variable, Energy performance analysis.
