  • Low-e glazing is classified as soft low-e glazing and hard low-e glazing. Hard low-e glazing can be temperable and its handling is comfortable because its coating film is a oxide film generated at high temperatures. But there is a fatal weakness that its insulation performance and shielding performance are lower compared to soft low-e glazing by low electrical conductivity of coating film. Soft low-e glazing is excellent because its coating film consists of Ag that is excellent electrical conductivity and it has strength that can supply various product consumers want. But soft low-e glazing has weaknesses that temperable and handling are difficult because Ag is oxidized easily. Therefore this study analyzes thermal performance of glazing by changing filling gas according to applying low-e glazing through simulation to judge performance before making sample. After this process, a comparative experimental study was done through TVS by making temperable low-e glazing.

  • The purpose of study is to estimate heating, cooling load performance and economic efficiency in office building with applied the functional paint. this paint can reduced SHGC(Solar Heat Gain Coefficient) on the glazing surface by coating. In this study, estimated to compared with double glazing, low-e glazing, IP(Insulation Paint) and IPu(Insulation UV-Cut Paint) coating glazing. As a result of this study, 1)heating & cooling load Analysis, SHGC value and U-factor of double glazing is about 0.70 and 3.29($W/m^2K$). low-E glazing is about 0.65 and 2.70($W/m^2K$). Two-side it is about 0.27 and 3.25($W/m^2K$). When compared to double glazing, annual heating & cooling load of low-E glazing, Two-side IPu and IP paint coating glazing is 3,012MWh($124kWh/m^2$), 2,910MWh($120kWh/m^2$), 2,867MWh($118.4kWh/m^2$) and 2,867MWh($118.4kWh/m^2$).

  • An energy loss through the window system occupies about 10 to 30 percent on energy consumption of the whole building. That is the reason, several elements for a building composition of window system are the weakest from the heat. Insulation performance increases for the reducing heat loss. Heat transfer through the window system that is reducing heat transfer through conduction, convection and radiation. Insulation performance reinforcement methods classify improving heat specific quality of window system and improving efficiency of whole window system. The most application method among each methods is reducing emission ratio of the window system(Low-E glass), increasing a number of glazing(multiple window) and a method of vacuuming between glazing and glazing. Therefore this study is investigated a sort of glazing and specific character, U-value calculation with changing glazing thickness and calculation of temperature distribution and U-value with a glazing charging gas kind from double glazing. For a conclusion, an aspect of U-value figure at the smallest value case of vacuum glazing with Low-E coating. That means insulation efficiency is the best advantage during a building plan selecting vacuum glazing with Low-E coating for a energy saving aspect. In this way, U-value become different the number of glazing, coating whether or not and selecting injection gas. Therefore selecting of glazing is very important after due consideration by a characteristic and use of building and consideration of strong point and weak point.

  • As the exterior of building has been considered one of th important parts, the use of glass that is suitable to express various appearances gets raised. However, windows have 6~7times lower insulating performance than insulated walls. Lately, highly efficient windows are required as the needs for reduction of energy consumption come to the force. Therefore, Nowadays more people use cooling systems in summer, more the use of Low-E glazing is increasing. Because it is good to block Solar Radiant Energy which can cause much of heat loss while cooling system is working. This study measures U-value of the double Low-E glazing window and commonly used single Low-E glazing window. And then the effect of each window on the efficiency rating has been analyzed applying to the certification system of the building energy efficiency rating which has implemented.

  • Apartment balcony has been indiscreetly remodeled since the government permitted remodeling on January 2006. But remodeled balcony has a few problems such as increase of heating energy, surface condensation and cold draft. The reason of thermal problem is mainly caused by the window system in a extended balcony. The purpose of this study is to analyze heating and cooling energy and propose the efficient window types for the extended balcony area of a apartment building. 4 types of window system which have fairly high U value in Korea are investigated as follows ; double clear glass, double low-e glass, triple clear glass and triple low-e glass. Comparing double clear 91ass with double low-e glass, triple clear glass and triple low-e glass, simulation results show that 10%, 7% and 15% saving of total primary energy can be expected.

  • Recently, more attention has been paid to DSC(Dye-sensitized Solar Cell) with the potential of glazing applications. The aim of the study is to analyze thermal and electrical performance according to composition of glazing with DSC. For this study, the electrical and thermal performance of glazing with DSC modules were measured and their result were compared. The measurement were performed according to the KS L2525 and with a solar simulator of DSC modules. The result show that the U-value of the DSC double glazings with clear glass and low-e glass were 2.78 $W/m^2K$ and 1.70 $W/m^2K$, respectively. The electrical measurement indicated that the electrical efficiency of the DSC double glazings with clear glass and low-e glass decreaced by 9.9% and 13.3%, respectively, compared to the DSC medules electrical performance.

  • 도심지내 대형화, 고층화 공사에서는 증가하는 자재의 종류와 양에 비해 한정된 공간과 장비의 제한 등의 문제로 효용성 제고가 요구되고 있어 물류관리의 중요성이 강조되어지고 있다. 이러한 제약들로 인해 공사비 증대, 공기지연, 생산성 저하, 안전사고 발생 등의 문제를 야기 할 수 있다. 이러한 현장 내 물류관리의 문제점들을 해결하기 위하여 적시생산(just-in-time. 이하JIT)관리개념에 대한 관심이 높아지고 있으며 건설자재의 기존 물류흐름 프로세스를 개선한 양중 및 조달의 다양한 시도가 이루어지고 있다. 현재 콘크리트와 같은 주요 자재의 JIT적용 연구는 이미 많은 연구와 수행이 진행이 되고 있으나 마감자재에 대한 연구는 아직 미비하다 하겠다. 이에 커튼월과 더불어 주요 마감자재라 할 수 있는 유리, 그중 Low-emissivity 복층유리(이하 Low-e 유리)를 적용하여 현재의 물류관리 흐름 파악과 JIT관리 적용시 발생하는 효과와 양중조달 시스템 개발방향을 제시하는 것이다.

  • An SHGC(Solar Heat Gain Coefficient) is a determinant of total flux of solar radiation coming indoor and a critical factor in evaluating heating and cooling load. U-value represents heat loss while SHGC denominates heat gain. Recently, windows with high solar gain, mid solar gain or low solar gain are being produced with the development of Low-E coating technology. This study evaluated changes in energy consumption for heating and cooling according to changes in SHGC when using double-layered Low-E glass and triple layered Low-E glass in relation to double layered clear glass as base glass. An Office was chosen for the evaluation. For deriving optical properties of each window, WINDOW 5 by LBNL, an U.S. based company. and the results were analyzed to evaluate performance of heat and cooling energy on anannual basis using ESP-r, an energy interpretation program. Compared to the energy consumption of the double layered clear glass, the double layered Low-E glass with high solar gain consumed $69.5kWh/m^2,yr$, 9% more than the double layered clear glass in cooling energy. The one with mid solar gain consumed $63.1kWh/m^2,yr$, 1% less than the base glass while the one with low solar gain consumed $57.6kWh/m^2,yr$, 10% less than the base glass. When it comes to tripled layered glass, the ones with high solar showed 2% of increase respectively while the one with mid solar gain and low solar gain resulted 5% and 11% in decrease in energy consumption due to low acquisition of solar radiation. With respect to cooling energy. it was found that the lower the SHGC. the less energy consumption becomes.

  • 냉난방을 사용하는 가정에서는 대부분 창문을 통해 열손실이 이루어지고 있는데 이를 방지하기 위해 Low-E 유리, 복층유리 또는 진공유리가 사용되고 있다. 본 논문에서는 진공유리 제작공정의 최종공정인 봉지공정에 대한 연구가 수행되었는데 기존 상압 접합이 아닌 진공챔버 내 접합이 고려되었다. 봉지과정의 효율성을 위해 진공챔버 내에서 히터온도에 따른 프리트 용융온도 및 접합시간을 최적화하였고 열응력으로 인한 유리 파손을 방지하기 위해 유리 예열온도를 최적화하였다. 이러한 결과를 바탕으로 성공적으로 진공유리를 제작하였고 측정된 열관류율은 약 $5.7W/m^2K$로 진공유리 내부압력은 약 $10^{-2}$ torr로 판명되었다.
