Ventilated facades systems have become a widely used solution for elevations of commercial buildings. Yet, those systems use metal frames and brackets that interrupt continuity of thermal insulation by creating point thermal bridges. The influence of anchorage systems on the total performance of walls is either neglected or simplified upon assumption that their influence is not important because the thermal insulation is thick enough. This article, based on three-dimensional analyses, demonstrates a significant impact of point bridges created by the anchorage systems of ventilated building facades on the heat loss. The results emphasize the need for individual calculations.

安装支架对通风立面建筑物热性能的影响

通风外墙系统已成为商业建筑立面广泛使用的解决方案。然而，这些系统使用金属框架和支架，通过创建点热桥来中断隔热的连续性。锚固系统对墙体整体性能的影响要么被忽略，要么被简化，因为它们的影响并不重要，因为隔热层足够厚。本文基于三维分析，展示了由通风建筑外墙锚固系统创建的点桥对热损失的显着影响。结果强调需要单独计算。
