  • As a reasonable energy policy has become required because of consuming substantial amounts of oil than others, the studies on energy consumption are in work for energy savings of buildings that spend up to 24% of total energy consumption. However, there aren't basic data on energy consumption and installationregulations for effective equipments in energy guzzled buildings. The best plan to reduce the building energy consumption is that the insulation performance should be improved because the insulation and airtight of building envelopes have an effect on the energy consumption basically. Thus, we should prepare the alternatives to improve insulation performance of envelopes and the efficiency of insulation performance of the window for reducing energy consumption.

  • The purpose of this study is to analyze daylight distribution and characteristics of light on the Korean traditional paper and to investigate a possibility as the shading systems. First of all, daylight distribution through the Korean traditional paper windows and doors of the Traditional House is analyzed at Genjaegotaek of the Asan Oeam Traditional Village. After making a model, the characteristics of light on the Korean traditional paper and Roller Shade fabric are analyzed Korean traditional paper has a good efficiency to diffuse the light and is less glare than Roller Shade fabric. In the present office buildings and apartmant houses, daylight characteristics of the Korean traditional paper windows and doors could be used as preliminary data to develop a window system which makes greatest performance of daylight.

  • 본 연구에서는 기존 교육시설에 설치된 알루미늄 합금 창의 2차원 정상상태 전열해석을 통한 열성능 평가를 수행하였다. 교육시설의 주요 창호재료로 적용된 알루미늄은 열전도율이 $175 \;Kcal/m^2h^{\circ}C$ 정도로 플라스틱 소재와 비교하여 매우 불리하여 기존 시설에 설치된 알루미늄 창호는 열손실의 주요인으로 지적되고 있다. 본 연구에서는 이러한 점에 착안하여 충남 서산지방에 위치한 대학건물의 알루미늄 합금 창호의 열성능 평가에 관한 연구를 수행하여 다음과 같은 해석 결과를 도출하였다. (1) 2차원 정상상태 전열해석을 위한 경계조건은 국토해양부고시 건축물의 에너지절약설계기준의 [별표 6] 중부지방 냉난방장치의 용량계산을 위한 설계 외기온 기준과 [별표 7]의 실내온도 기준을 적용하여 여름철 실내 $27^{\circ}C$, 실외 $31.3^{\circ}C$, 겨울철 실내 $21.0^{\circ}C$, 실외 $-9.6^{\circ}C$ 로 설정하고 해석한 결과 열관류율은 알루미늄 합금 창호는 $U=9.631 \;W/m^2K$, 복층유리 $U= 2.382 \;W/m^2K$로 여름철과 겨울철 동일한 해석결과치가 산출되었다. (2) 산출된 열관류율 해석결과를 건축물의 에너지절약설계기준 [별표 3] 열교차단재가 적용되지 않은 금속제 창의 단열성능 중 일반복층창 성능기준인 $4.0 \;W/m^2K$와 비교할 때, 알루미늄 창틀을 통하여 225%의 열량이 손실됨을 보여 주고 있다.

  • 본 논문에서는 분산공유메모리 다중프로세서 시스템에서 하드웨어 구성요소와 실행환경이 시스템의 전체 성능에 미치는 영향을 시뮬레이션을 통하여 분석한다. PARSEC[1,2]을 이용하여 분산공유메모리 다중프로세서 시스템을 실제 실행환경에 근접하게 모델링하고 그 모델링된 시스템상에 2D FFT를 가상 실행하는 방식의 시뮬레이션 결과, 일반적으로 성능분석을 할 때 성능요소로 고려하지 않는 군소 하드웨어 요소들이 시스템 구성에 따라 시스템의 전체 성능에 상당한 영향을 미침을 밝힌다. 또한 반복순환 구문의 오버헤드, 코드최적화 등 실행조건에 따른 성능의 변화도 정량적으로 분석한다.

  • Window system is an essential component for lighting, ventilation and thermal environment in buildings. Moreover, as balcony extension in apartment houses become legalized, the performance requirements of window systems in balcony space are getting complicated. However, at this moment, five properties of the windows are used to represent the performance aspects of the system, including wind resistance, air tightness, water tightness, sound insulation, thermal resistance. And such single properties are not capable to express the performance of a space with the window systems in terms of performance concept. A performance analysis with wholistic approach is required to see the effect of the window system in built environment. Thus, performance-based approach should be established, which will be able to evaluate the goal/function and comfort of occupants/owners. As the first step to develop the performance indicator for the window systme for balcony space, this study conducts a survey to find the required performance aspects. A complete set of performance-based indicators will be developed with verification methods in the later stage of research.
