This study is intended to analyze the thermal performance and evaluate the applicability about non-duct type heat recovery ventilation system integrated with window. Eventually, economic analysis of the system is conducted according to building energy saving ratio of it. As results of the thermal performance, the U-factor of the window conducted on the basis of KS F 2278 appears to 1.8 W/㎡K, and the effective heat exchange efficiency of the ventilator conducted on the basis of KS B 6879 appears 49.95% for cooling, 66.89% for heating. In the applicability evaluated by TRNSYS 16, the caes of applying the heat recovery ventilator integrated with window is found to reduce the cooling or heating load by 2.9% or 13.5% than the non-ventilator case. The results of economic analysis taking a side of consumer is verified as the payback is 3 years, and the accumulated earning is 1,408,133 won in terms of ‘600,000 won/unit’ for initial cost, 10 years for useful life of the system.

Purpose of this study is proposal of estimating method about window thermal performance that based on KS F 2278 'Test method of thermal resistance for windows and doors' due to material composition of PVC frame window. First step of this study is research of present state about material composition of PVC frame window. Second is selection of main effective elements about window thermal resistance. For example, composition of Glazing, Frame area ratio of total window area, frame width, opening type, area of heat transfer and so on. Third is multiple regression analysis about thermal performance of PVC frame window due to main effective elements. It produces equations of multiple regression analysis due to opening type. Case of sliding window is Y = 0.149 + 0 .034X<SUB>g</SUB> + 0.248X<SUB>far</SUB>, 4track sliding is Y = 0.584 + 0.175X<SUB>g</SUB> + 1.355X<SUB>far</SUB> -0.008X<SUB>fw</SUB>, Tilt & Turn window is Y = -0.161 + 0.076X<SUB>g</SUB> + 0.576X<SUB>far</SUB> + 0.0008X<SUB>fw</SUB>.

This present study analyzed temperature depreciation ratio of window inside surface by KS F 2295 "Procedure for determining fenestration product condensation resistance values". it estimated window indoor surface condensation due to variable environmental condition. Performance of condensation resistance by using temperature depreciation ratio until applied Low-e and Ar glazing improved about 45% from 24 ㎜ clear. Temperature depreciation ratio by KS F 2295 considers analytic index of window condensation due to variable boundary condition.

The purpose of this study is to investigate continuance of window condensation followed by diffusion and retardation by the factors of indoor vapor occurring. It's necessary to extend the application limit of indoor condition of performance test on the prediction and the level about a condensation occurring on the window to analyze influence of vapor in the air in the room over condensation occurring on the window. It measured the infiltration of the selected house by pressurization test. The result of the test is applied to input parameter of TRNFLOW simulation program of multi zone air flow. On the other hand, It gets the surface temperature decrease of the selected window by Therm 5, heat transfer analysis program of window element. Surface temperature decrease is used to estimate condensation of window surface. Finally, it investigates continuance of window condensation followed by diffusion and retardation by the factors of indoor vapor occurring. In the result of the research on diffusion and retardation of vapor, condensation occurs more in a zone with less infiltration than in other zones. Condensation can often occur in Non-heating spaces.

Heat loss by window in building occupies about 1/4 of energy amount used building. Therefore, high thermal insulation of windows system can speak as very important part in save energy of building. in this research, After select most suitable frame design and Glazing system for high thermal insulation of windows, execute simulation of mixing frame and Glazing System. Also, manufacture windows with the result and execute verification experiment, with verified simulation, this research evaluated thermal insulation performance of window by Glazing System's change.
