Abstract

At present, in the case of small and medium window manufacturers in South Korea, glazing and window frame manufacturers are divided into separate businesses. However, in the fenestration energy consumption efficiency rating system and the energy-saving design criteria for buildings, the coefficient of overall heat transmission standard for windows is defined by window sets, which integrate glazing and window frames. At most construction sites, windows are constructed by installing separately supplied glass and frames. Research that can integrate the reality and the system is therefore necessary. The present study first investigated and analyzed the on-site situation of the fenestration energy consumption efficiency rating system. According to the results, while overall understanding of the fenestration energy consumption efficiency rating system was high, satisfaction with it was low, and the general practice at construction sites was to use windows assembled on site rather than integrated window systems manufactured at factories, thus making it difficult to confirm that the current rating system was well applied on site. Consequently, the reality of industrial sites must be reviewed and a realistic alternative to the fenestration energy consumption efficiency rating system must be presented instead of focusing on theory.

현재 우리나라의 중소창호업계는 글레이징과 창프레임 제조가 별도의 산업체로 분리되어 있다. 그러나, 창호에너지소비효율 등급제와 건물의 에너지절약설계기준에 따르면, 창호의 열관류율 기준은 글레이징과 창프레임을 일체화시킨 창세트에 의해 정의된다. 대부분의 창호제조 중소업체는 글레이징과 프레임부분을 통합하는 생산체계를 갖추지 못하고 있으며, 대부분의 공사현장에서 창호는 별도로 납품된 유리와 프레임을 설치하는 방식으로 시공된다. 이러한 현실과 제도를 연결할 수 있는 연구가 필요하다. 본 연구에서는 우선 창호에너지소비효율등급제의 현장상황을 조사 분석하였다. 그 결과, 창호에너지소비효율 등급제에 대한 이해도는 전반적으로 높았으나, 만족도는 낮았으며, 공사현장에서는 공장제조된 일체화된 시스템의 창호가 아니라 현장조립에 의한 창호를 사용하는 것이 일반적으로, 현재의 등급제가 현장에서 잘 적용된다고 확신하지 못하는 상황이었다. 따라서, '창호에너지소비효율등급제'는 산업현장의 현실성을 돌이켜보고, 이론적으로 치우칠 것이 아니라, 현실적인 대안을 제시해야 한다.
