There are many economic and operational reasons to integrate fire alarm signaling system with other building automation system. Integration of this requires communication standard and careful design practices. The important point for this is also the development of intelligent control modules for replacing the conventional zone adapter in fire system. Therefore, this paper proposes an new conceptual design of the distributed fire alarm signaling system and a new intelligent control modules with LonTalk protocol. Newly proposed additions to LonWorks network make it very well suited for integrating fire systems with other building automation systems. Additionally, it is very important that best design practices, test procedures and building codes need to be modernized to accommodate Integrated building systems.

This paper experimentally investigates the effectiveness and applicability of the time delay control (TDC) algorithm, which is simple and robust to unknown system dynamics and disturbance, for an active mass damper (AMD) system to mitigate the excessive vibration of a building structure. To this end, the theoretical background including the mathematical formulation of the control system is first described; and then, a thorough experimental study using a shaking table system with a small-scale three-story building structural model is conducted. In the experimental tests, the performance of the proposed control system is examined by comparing its structural responses with those of the uncontrolled system in the free vibration and forced vibration cases. It is clearly verified from the test results that the TDC algorithm embedded AMD system can effectively reduce the structural response of the building structure.

The aim of this study is to evaluate how much would the building energy consumption be saved by applying DSSC BIPV window which is possible to control the transmittance and express the color in the office building. For this, physical characteristics such as transmittance and reflectance, U-factor of DSSC areanalyzed and an annual energy consumption that is connected to dimming control is calculated when DSSC BIPV window is applied by alternate clear window system. As a result, It is possible to reduce the anannual energy consumption as much as4.1% by just change the clear double window system to DSSC BIPV double window system because the major factor to reduce energy consumption in the office that has much cooling load than other building is SHGC. When the thermal insulation properties of DSSC BIPV window with low-e coating and making triple window are improved, energy saving ratio is about 9%. Plus, energy saving ratio of 25~28% in lighting energy consumption is possible when the dimming control system with DSSC BIPV window is adopt.

The objective of this study is to propose the basic design plan of system by comparing and analyzing application environment of lift and elevator group control system, as preliminary study for the application of group control system to lifts for high-rise construction. The basic design plan is suggested in terms of group control algorithm, hall call system type, operation information recording device, information communication method, and operation method. The results of this study can be used as basic data for software and hardware design for application of group control technology of lifts for super tall building construction and ultimately contribute to improve the operation efficiency of lift for high-rise construction.

A hybrid mid-story seismic isolation system with a smart damper has been proposed to mitigate seismic responses of tall buildings. Based on previous research, a hybrid mid-story seismic isolation system can provide effective control performance for reduction of seismic responses of tall buildings. Structural design of the hybrid mid-story seismic isolation system is generally performed after completion of structural design of a building structure. This design concept is called as an iterative design which is a general design process for structures and control devices. In the iterative design process, optimal design solution for the structure and control system is changed at each design stage. To solve this problem, the integrated optimal design method for the hybrid mid-story seismic isolation system and building structure was proposed in this study. An existing building with mid-story isolation system, i.e. Shiodome Sumitomo Building, was selected as an example structure for more realistic study. The hybrid mid-story isolation system in this study was composed of MR (magnetorheological) dampers. The stiffnessess and damping coefficients of the example building, maximum capacity of MR damper, and stiffness of isolation bearing were simultaneously optimized. Multi-objective genetic optimization method was employed for the simultaneous optimization of the example structure and the mid-story seismic isolation system. The optimization results show that the simultaneous optimization method can provide better control performance than the passive mid-story isolation system with reduction of structural materials.

본 논문에서는 건물의 3D 모델링을 바탕으로 무선 센서 박스의 수집 정보를 이용한 디지털 트윈 기반의 건물 관제 시스템을 제안한다. 기존 유선 방식의 센서 대신 무선 방식의 센서를 통해 설치 및 적용성이 높은 장점을 가지며 3차원 모델링을 통한 직관적인 건물 관제를 가능하게 한다. 또한 BIM 데이터를 통하여 효과적인 관제와 시각적 표현이 가능한 정점을 가진다. 센서 박스는 다양한 센서 모듈이 추가될 수 있게 범용적으로 설계하였고 실제 대학 건물을 대상으로 구현하여 이용 가능도가 높음을 증명하였다. 본 연구의 결과는 향후 디지털 트윈 관제 플랫폼 구현에 활용될 수 있을 것이다.

In this paper, a development of agent-based IEDs(Intelligent electronic devices) for integration control of building microgrid in smart green building are proposed. To manage and control this complex energy system of smart green buildings, multi-agent system based networks is needed. Thus, several IEDs for utilizing multi-agent system are developed and modified for the their verification of performance as agent modules functions in the integrated experimental equipment. The good performance of these IED agents are verified from experimental results obtained from seamless bi-directional communication by SOAP/XML protocol between PC agent and IED agent.

Optical devices and electronic equipments used in the laboratory of the synchrotron light source building of the accelerator have stringent vibration limits. In order to control the vibration of the building structure and HVAC systems which are main vibration sources are evaluated using experimental modal analysis. Double anti-vibration system is used for the HVAC system and results show that the double anti-vibration system reduces the vibrations of the building to acceptable levels.

최근 기후변화로 인한 외부 열환경이 악화되고 있으며, 이로인한 건축물에너지사용량이 상승하고 있다. 기후변화 대응형 건축물 저에너지 기술 성능평가를 위하여 Energy Plus를 활용하였다. 실험군 유형은 기본건축물(Control)과 기화냉각시스템(EMS)이며, 유형별 분석결과를 비교하였다. 에너지성능평가결과 냉방피크부하는 Control 대비 EMS에서 약 9% 이상 저감률을 보였다. 단위면적당 연간 냉방부하는 Control 대비 EMS에서 약 17% 이상 저감률을 나타내었다. 단위면적당 연간 에너지사용량은 Control 대비 EMS에서 약 10% 이상 저감률을 보였다. 따라서 건축물 에너지저감기술로 기화냉각시스템의 효과는 양호한 것으로 판단되었으며, 향후 기화냉각시스템의 분사량 및 이격거리에 따른 건축물에너지성능평가 연구가 진행되어야 할 것이다.

건축물에서의 연기제어 시스템과 관련하여 국내에서는 거실에 대한 배연기준과 피난계단 및 부속실에 대한 제연기준이 제시되고 있으나, 대형화 고층화 복합화 되어가는 첨단 건축물에 대한 적용성을 검토하면 국내 설계기준에 따른 연기제어 시스템은 화재시 연기안전을 확보하기 곤란할 수 있다. 따라서 대형 고층 복합의 첨단 건축물에 대한 화재시 연기안전성을 높이고 화재와 건축물 특성에 따른 상호 연기제어 연계성 확보와 통합적 설계가 가능한 성능위주 연기제어의 적용이 요구된다. 본 논문에서는 국내 연기제어 기준을 분석하고 개선이 필요한 부분을 제시하였으며, 선진외국에서의 성능위주 설계 수행에 대한 법체계와 성능위주 연기제어 설계의 지침을 조사하고 분석하였다.
