In order to reduce the energy consumption of the building, much effort is being made. The problems are that excessive solar radiation in summer and the heat loss in winter by the increase of window area. To prevent this problems, government limited the window area ratio or the performance of windows in new buildings. In order to reduce energy consumption of the existing buildings, the window film insulation is spotlight because the window film insulation was simple to installation. This study confirmed the performance of the window film insulation and affect to heating & cooling load of buildings. The impact of the window film insulation coating was confirmed by experiment. And this study confirmed the annual heating & cooling load by simulation. As a results, the surface temperature of coated window was higher than the surface temperature of existing window. The window film insulation was increased surface temperature of window. And this study confirmed that the increased surface temperature was slightly affected the room air temperature through experiment of the insulation box. The results of the heating and cooling load by simulation, this study confirmed that the case of coated window film insulation decreased cooling load in summer and increased heating load in winter. Also the annual total heating & cooling load was increased a little in the case of coated the window film insulation.

| 창호의 성능 개선을 위해 에너지 관리공단에서는 창 세트의 ‘효율등급제도’를 통해 단열성능과 기밀성능에 따른 등급을 정하여 창호의 성능을 구분하였는데, 문제점은 무엇인가? | 창호의 성능 개선을 위해 에너지 관리공단에서는 창 세트의 ‘효율등급제도’를 통해 단열성능과 기밀성능에 따른 등급을 정하여 창호의 성능을 구분하였다.하지만 광학적인 성능은 다루지 않아 여름철 과도한 일사를 방지하기 위한 제도적 규제가 미흡한 실정이다.새롭게 건축되는 건물에서는 창호의 성능을 고려한 창호 설계가 이루어지고 있으나 기존의 건축물에는 리모델링을 통한 창호의 교체가 이루어져야 하기에 실질적으로 창호의 성능 개선이 쉽지 않은 상황이다. | |
| 열 차단 필름을 부착한 창호의 표면온도가 더 높게 나타나는 이유는 무엇인가? | 이를 통해 열 차단 필름을 부착한 창호의 표면온도가 더 높게 나타나는 이유는 열 차단 필름이 태양 일사를 흡수하여 창호의 표면 온도를 상승시킨 것으로 판단된다. | |
