지역별 창의 종류에 따른 에너지 절감율과 경제성 평가 연구

The purpose of this research is based on the energy use in buildings which takes up about 25% of the country in this high inflated society. Therefore, the need of strengthening the promotion of effective use of energy is becoming prominent, and especially windows and doors are seen as the parts which generates the biggest loss of energy. Amongst of all, due to the increase of the rate of sizes in windows, we are facing with lots of windows and doors fragile in its use. We have searched for the types, prices and heat flowing rate of each of the glasses and frames through the pre-research on industrial building, and after the application of changing the amount from previous standard duplex window to Low-E glass, 3 layed Low-E glass, aluminum frames and PVC frames, we have proceeded the simulation by using the web tools to assure the effectiveness on energy savings. Also, by using the prices of windows and flames, we have derived the best window systems and compared the major systems in its use of effective energy and in the perspective of economy, to find out which system would be most appropriate.
