Enhancement of exterior's insulation performance like wall or window etc. is general way for building's energy efficient and thermal performance. In this paper, energy saving rate will be analyzed and compared considering the window‘s thermal performance in a apartment with Building Energy Rating System's evaluation tool. In the process of evaluation, energy saving rate is measured at each stage of the window's thermal performance from 3.3 to 2.0. As a result of this research, reduction rating of heating energy depending on the building law in comparision with standard house will be used in a plan for degree of Building Energy Efficiency Rating System. |
