Building envelope is important system affecting energy consumption of the building. The thermal performance of a wall is represented by simple R-value. The modified zone method is a simple method for estimating the clear wall R-value of steel stud walls with insulated cavities. However, this analysis does not consider the thermal bridges impact of connection with other building components. The purpose of this study is to investigate the thermal impact of thermal bridges on the thermal performance of curtain walls. Simulation was performed by Physibel Trisco based on 3-D finite difference computer modeling. The R-value of Stone and GFRC(Glass Fiber Reinforced Concrete) panel system were calculated considering connection components which cause thermal bridges in curtain walls. The result of simulation show that steel components of curtain wall have important impacts on the overall wall thermal performance and thermal bridging impact of the connection with other building component is important especially in the case that steel component such as fastener has important impacts on the thermal performance of the wall. |
