본 연구는 기존 건물 외벽에 일반적으로 사용되는 일반벽체(기준모델)와 건물 외벽 1면에 부착되는 투과형단열재 벽체(비교모델)의 열성능 비교?평가를 직접 개발한 수치 시뮬레이션 프로그램에 의해 이론적으로 분석하는 것이다. 이를 위해 투과형 단열시스템의 구성요소들의 변화에 따른 복사와 전도에 의한 열손실율 및 전체 열관류율 특성을 분석하였고, 수치시뮬레이션 프로그램을 통해 각 벽체 표면온도, 자연실온 및 냉?난방부하를 비교하였다. |

Global efforts have made to reduce energy consumption and CO2 gas emission. One of the weakest parts for energy loss through the whole building components is building envelopes. Lots of technologies to increase the thermal performance of building envelopes have been introduced in recent year. Transparent Insulation Wall(TIW) is a new technology for building insulation and has been function both solar transmittance and thermal insulation.
A mathematical model of a Transparent Insulation Wall equipped with south wall was proposed in order to predict thermal performance under varying climates(summer and winter). Unsteady state heat transfer equations were set up using an energy balance equation and solved using Gauss-Seidel iteration solution procedure. The thermal performance of the TIW determined from a wall surface and air layer temperature, non-airconditioned room temperature and air conditioning load. As a result, this numerical study shows that the TIW is effective in an air conditioning load reduction. Further experimental study is required to establish complete TIW system. |
