| 요약2 | To reduce building energy consumption, it is important to ensure that building envelopes have excellent thermal insulation performance. However, the actual insulation performance of building envelopes varies depending on components and construction methods. In particular, in metal-exterior curtain wall panel systems, various thermal bridges exist at the vertical and horizontal joints between metal panels and in fixing units such as brackets and screws. These thermal bridges can degrade the actual thermal insulation performance even if the insulation thickness is sufficient to meet the insulation standards. Therefore, it is necessary to evaluate the energy consumption and construction cost of highly insulated metal-exterior curtain wall panel systems without thermal bridges. In this study, the annual heat loss and gain of the existing metal-exterior curtain wall panel system and those of two alternatives for reducing thermal bridges were evaluated through a three-dimensional transient heat transfer analysis. The annual energy cost and the construction cost per unit area of a wall were determined, and the life cycle cost of the example building was analyzed. The annual energy cost and construction cost of the second alternative were less than those of the conventional system by 68.2 % and 2.5 %, respectively; the life cycle cost for 20?40 years was also less than that of the conventional system by 7.5?9.4 %. |
