Analysis on Energy Performance of Educational Facility by Composition of Double Glass

Abstract

Korean energy consumption accounts for about 40 percent in the architecture. Especially, Heat loss of the windows is about eight times larger than the wall or roof. In addition, the structures older than 20 years were designed with no consideration of the energy perspective, and they have low energy efficiency compared with the newly introduced structures, which leads to extreme energy consumption. Therefore, this study was conducted for the purpose of engergy performance analysis according to window type in educational facilities. This study we medeled the university library in Autocad Ecotect Ananlysis program, 3D modeling. It calcualted data that the air layer thickness has about 3.9 times more impact that the glass thickness in composition of double glass. As the result of this study, the need for the remodeling and renovation of the obsolete library in order to reduce its excessive energy consumption was highlighted.
