The purpose of this study was to achieve preliminary data of wind effects on condensation performance of window though experiments. Seven different windows were used to test in artificial climate chamber under the same indoor and outdoor temperature condition with only change in wind speed. We measured surface temperature of windows and calculated ratio of temperature decrease to evaluate the performance of windows. From the test result, the surface temperature of window decreased maximum of 7℃ in 6~8㎧ wind speed, which we concluded, wind effects the performance of window from the experiments.

The purpose of this study is to investigate the performance of reflective insulation system(RIS) and examine the thermal resistance of air space within various RIS. RIS is a type of thermal insulation with one or more reflective surface including one or more enclosed air space. In this study, the thermal resistances of single air space facing the reflective surface are 0.26㎡ㆍK/W at 10㎜, 0.43㎡ K/W at 20㎜ and 0.45㎡ㆍK/W at 30㎜ respectively. There is no difference in thermal resistance when the enclosed air space is facing single reflective surface or both reflective surfaces. The result shows that RIS with EPS(thermal conductance : 0.032W/mㆍK) and reflective insulation materials can reduce the insulation thickness about 27% than EPS only. Because the insulation performance of RIS depends on the thickness and temperature of air space, direction of heat flux, emissivity of surface facing air space and so forth, the more detailed evaluation should be done before applying RIS.

Curtain wall systems are an important aspect in the design of most buildings. They play a rote in defining a building's aesthetics both from the view point of appearance as well as occupant considerations of visual and thermal comfort and general feelings of well-being. When designing curtain wail, the problem of dew generation on aluminum surface an make rust on tine connecting joint as bolts and nuts. This can be the severe damage to the curtain wall. Two-dimensional heat transfer through aluminum frame involving fenestration system, subject to design condition(outdoor temperature -18%, indoor temperature 20%, 30%) was numerically modeled in this study. Two-dimensional turbulent natural convection over an indoor aluminum frame involving fenestration system was numerically simulated in order to obtain the iso thermal line distributions. From the result, dew point iso-thermal line was detected at the surface of aluminum.

In Korea, apartment housing is usually located near road continuously causing complaints morf traffic noise and outdoor environment noise. Mainly, noise from outdoor is blocked by building facade such outer wall, windows and so on. Recently, the deletion of the balcony space results in falling the sound insulation performance. Accordingly, in order to isolate the noise, sound insulaton performance of windows are very important. In this research, 7 type of windows are investigated by sound insulation performance. And sound intensity measurement is performed to find the sound defect area of windows.

On trends of 'well-being', heat recovery ventilators(HRV) are recently installed in high rise buildings. HRV is not energy saving instrument but ventilating one. But many people have not been aware of the accurate fact. In this study, performances of HRV are tested under foreign and domestic standards. Especially air-tightness is measured three times by using gas concentration method and pressing equipment. Net effective ventilating air volume is acquired by solving gas concentration equations. After research air-tightness and effective ventilating air volume must be more focused on than heat transfer efficiency to select the optimal HRV. Heat transfer efficiency must be adjusted by air-tightness results.
