고효율에너지기자재 고기밀성 창호의 기밀성능 평가 연구

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 dissemination by basic information.,through a evaluation on airtight performance of the window of high efficiency energy equipment which can improve the airtight performance.
