The curtain wall is presently being adopted widely in high-rise buildings because of its several merits in many aspects. Curtain walls, however, also have problems, such as thermal efficiency and moisture condensation, especially in countries where there are four seasons like Korea, because of wide glazing windows and metal frames that have high thermal conductivity. Many researchers have tried to predict the surface temperature of windows or curtain walls precisely. But most of the research has focused on small-scale window rather than large-scale curtain walls. Thus, a study on the comparison between a computer simulation and a mock-up test using a large-scale thermal chamber for the curtain walls is needed. There are two main objectives in this study: first, to understand the reasons for the differences between the results of the thermal mock-up tests and those of the simulations: second, to understand the differences in the simulation methods. For 12 curtain walls, the mean temperature difference between computer simulations and the mock-up tests was about 2.6 . The simulation method (NFRC) considering convection and radiation showed closer result to the mock-up test than conventional simulation method. |
