  • Currently the country's foreign energy dependence reaches approximately 97% and the total energy consumption percentage of buildings(commercial and domestic parts) reaches approximately 24%. Building energy saving by enhanced insulation will be very important issue. Therefore, the solution is required to reduce energy loss and increasing displeasure caused by excessive influx of solar energy through windows, to solve the problems like decoloration on indoor furniture an clothes by harmful ultraviolet rays, air conditioning and increased cost. This research used for commercialization and ills semination by basic information through a evaluation on insulation performance of the window of high efficiency energy equipment which can improve the insulation performance.

  • The parts of building which has the most influence on thermal load are skins, outer walls and windows. Among them, window is the worst weak point of building even if it has many advantage of solar radiation gain than other parts. The present time, many researches on various performance of window and many types of system-window are being made. This study evaluates thermal performance of tilt & sliding system window by simulation program Therm 5.2 and Window 5.2. After making a sample model improving it's thermal weak point, this study evaluates real thermal performance of system window. As a result, this study understands manufacture ability condition of domestic company and proposes a research plan of system window.

  • The purpose of this study is to analyze and compare the life cycle cost of window glass with insulation film and regular glass, to verify an economical window construction method. As an approach method, the thermal performance data of each type of glass was measured using Window 6.3 and ECO2-OD Simulation Program, applied it to the case building to calculate the air conditioning and heating maintenance costs and LCC, and compared the economic feasibility. As a result, installing an additional insulation film prevents the solar heat penetration in the summer, so it reduces the cooling cost, on the other hand, it increased heating cost in winter. From the life cycle cost perspective, the effect of cooling cost reduction does not counterbalance the increase in heating cost and the additional cost from film installation and repair; therefore, the installation of insulation film may not be a proper method.

  • 국내 에너지 소비량의 21.6%가 건물 분야에 소비되고 있다. 창호는 벽체에 비해 8~10배 이상 낮은 단열 특성을 가지기 때문에 열 손실량이 크다. 유리는 창호를 이루는 요소 중 가장 큰 면적을 차지하고 있으며, 창호의 단열성능을 2배로 향상시키면 30% 이상 건물의 에너지 절감 효과를 가질 수 있다. 창호의 단열 성능을 향상시키기 위해서 Low-e(emissivity) 기술 연구가 진행 중이다. 이번 실험에서는 RF 마그네트론 스퍼터링 시스템을 사용하여 XG 유리기판 위에 ZnO박막을 증착하고, evaporator 장비를 사용하여 metal층인 Ag를 증착하였다. 그리고 다시 한번 ZnO박막을 증착하였다. Low-e 연구에 활용할 수 있는지를 확인하기 위해 XRD, AFM, 투과도를 측정하였다. ZnO박막의 증착 조건은 초기압력 $3.0{\times}10^{-6}$ Torr, 공정압력 $2.0{\times}10^{-2}$ Torr, RF파워 30 W, Ar gas는 50 sccm, 증착온도는 상온으로 하였다. Metal층인 Ag를 증착하기 위해 evaporator의 증착 조건은 Rotate rate 2 rpm, voltage 0.3V, 공정압력 $5.0{\times}10^{-6}$ Torr이며, 변수로 Ag두께를 3,5,7,9,11,13,15 nm로 하였다. AFM 측정결과 Ag두께가 증가할수록 RMS roughness값이 높아졌으며, 최소 0.71 nm의 거칠기를 가지는 것을 확인하였다. XRD분석결과 37도 부근의 피크가 발생하여 ZnO 박막이 결정질 구조임을 확인할 수 있었다. 그리고 UV-Visible-NIR 분광 광도계를 이용하여 광학적 투과를 측정한 결과 Ag두께가 13 nm일 때 가시광 영역의 투과도가 최대 75%, 적외선 영역의 투과도가 최소 28%로 좋은 차단 특성을 가지는 것을 확인하였다. 위 결과들로 ZnO 박막이 Low-e 기술에 활용될 수 있음을 확인하였다.

  • In the high oil price age, intensification of energy efficiency promotion in the building sector is required. Windows are dominating in large percent of whole building loads, and are regarding as the primary target of energy efficiency. In this study, in order to reduce heat loss of buildings, we investigate the thermal performance properties of Temperable Low-e glazing coated Ag membrane that has high electrical conductivity. The Temperable Low-e glazing windows has high insulation and shading properties, and it has strength that can supply various product which consumers want. In order to evaluate thermal performance of temperable windows, we install single low-e windows and double low-e windows in the experimental chamber and analysis the comparison heating energy consumption between single and double Low-e glazing windows. performance evaluation was conducted.

  • Windows have an great effect on annual building load because windows are the weakest parts of building envelope thermally. To reduce the consumption of building energy, the thermal performance of window has to be improved in first place. Therefore this research aims to make a quantitative analysis of the heating and cooling load according to the window thermal performance using the heat load simulation program. As a result of the simulation, annual heat load is down 38% according to the decrease of U-value of window, 1.00 W/$m^2K$. and annual heat load is up 10% according to the decrease of shading coefficient, 0.20. The annual load of the window with Low-E glass is 15% lower than the window with pair glass.
