The building facade plays important role for not only appearance designs, but also the safety and the environmental impacts. For satisfying these demands, the authors have proposed the integrated facade system using horizontally arranged louvers. Considering the safety, not only the structural aspect but also fire safety is important. Especially verification of the ejected plume behavior from opening is important to prevent fire spread. The full scale fire experiment, which attached opening with the louver system, was carried out. The ejected plum behavior from this opening was confirmed through temperature around opening and louver, shape of plume, and radiated heat.
