본 논문에서는 미래 지능형 빌딩 시스템에서 요구되는 다양한 상황을 인지할 수 있는 지능형 디지털 통합 전관 방송 시스템을 개발하였다. 화재와 재난과 같은 응급 상황이 발생할 때 울리는 경보음을 인식할 수 있으며, 실내 온도와 습도 및 환경 오염도와 같은 다양한 센서 출력을 전달 받아 지능적으로 상황에 맞는 대처 방안을 필요한 곳에 개별적으로 방송할 수 있는 지능형 디지털 통합 전관 방송 시스템을 개발하였다. 외부 입력, 마이크, CD와 MP3 및 라디오 기능 등을 일체형으로 통합하고 소형화한 디지털 전관 방송 시스템을 개발하고 있으며, 시스템이 중앙 집중 제어가 가능하도록 운용 MICOM을 개발하였다. 중앙 집중 제어를 수행하기 위해 운용 MICOM은 제어 계층, 처리 계층 및 사용자 인터페이스 계층인 3계층으로 구성된다.

건축물의 바닥판에 대한 합성슬래브 시스템의 사용이 점차 확대되어 오피스 빌딩을 중심으로 널리 사용되고 있다. 최근에는 주상복합형 및 주거용 건물에 대한 확대 적용을 휘해 하부면이 평탄한 플랫 데크플레이트의 필요성이 대두됨에 따라 플랫 데크플레이트가 개발되고 있다. 또한 합성슬래브시스템의 바닥판 상부에 와이어메쉬 대신 일체형으로 생산되는 익스팬디드 메탈을 적용할 경우, 원가 절감, 공기 단축 효과도 기대할 수 있을 것이다. 본 연구에서는 익스팬디드 메탈을 와이어메쉬의 대체재로 사용하여 이를 하부면이 평탄한 플랫 데크플레이트와 결합시킨 신형식의 합성블래브시스템을 제안하였다. 총 12개의 시험체에 대한 실험을 통해 그 구조성능을 평가하고자 하였다. 실험 결과는 시험체의 최대내력과 파괴거동 등을 중심으로 요약하여 나타냈다.

Finding sufficient supplies of clean energy for future is one of the society's most important challenges according to technologies. Alternative renewable energy source such as sun energy can be substituted for exceeding human energy need. The main factor affect to solar performance is a collective intensity. To enhance intensity, suitable equipment is a solar tracker. This paper presents design and evaluation of 1 layer polar motion control system for solar tracker suitable for building integrated system. To evaluation of tracking accuracy and adaptability, solar tracker with 64 links is implemented. In experimental results, the accuracy of tracking has under ${\pm}0.0287^{\circ}$ and the thickness has under 140mm.

The increasingly high prices for oil, the exhaustion of fossil fuels as well as concern about global warming are driving rapid growth of alternative sources of energy in the world. The active solution for global environment and exhaustion of energy sources is to develop and popularize the technologies to use natural energy such as sunlight, wind, and water. PV(Photovoltaic) modules are efficient devices that has been considered a logical material for use in buildings. Recent advanced BIPV(Building Integrated PV) technology have rapidly made PVs suitable for direct integration into construction in the world. Recently, building has been higher and higher. Tall buildings have many advantages for BIPV such as wide facade area and no shading effect by the surrounding buildings. However. BIPV has not been applied for tall building facade yet. Therefore, the purpose of the research is to develop suitable BIPV for tall buildings and to put these technologies to practical use. Therefore, the purpose of the study is to investigate unification of BIPV to curtain wall to apply BIPV on tall building through research into advanced application of overseas BIPV cases.

Korea has been at the forefront of green growth initiatives. In 2008, the government declared the new vision toward 'low-carbon society and green growth'. The government subsidies and Feed-in Tariff (FIT) increased domestic usage of solar power by supplying photovoltaic housing and photovoltaic generation systems. Since 2000, solar power industry has been the world's fastest growing source with the annual growth rate of 52.5%. Especially, BIPV(Building Integrated Photovoltaic) systems are capturing a growing portion of the renewable energy market due to several reasons. BIPV consists of photovoltaic cells and modules integrated into the building envelope such as a roof or facades. By avoiding the cost of conventional materials, the incremental cost of photovoltaics is reduced and its life-cycle cost is improved. When it comes to atypical building, numerous problems occur because PV modules are flat, stationary, and have its orientation determined by building surface. However, previous studies mainly focused on improving installations of solar PV technologies on ground and rooftop photovoltaic array and developing prediction model to estimate the amount of produced electricity. Consequently, this paper discusses the problem during a planning and design stage of BIPV systems and suggests the method to select optimal design of the systems by applying the national strategy and economic policies. Furthermore, the paper aims to develop BIM tool based on the engineering knowledge from experts in order for non-specialists to design photovoltaic generation systems easily.
