+For economic reasons, the square version might be the best option, as only one heat exchanger is necessary in this case. However – depending on the necessary flow rate – the heat exchanger and consequently the  diameter of the core hole can become quite large. Whether core hole drilling of the respective diameter is permissible for static reasons must be checked on a case-by-case basis.
+===== Summary =====
+Within the outPHit project, several options for façade integrated ventilation systems were investigated and demonstrated by various prototypes. A checklist and a tool will help for planning and quality assurance.
+When planning a renovation, the first thing to decide is where the device can be installed as easily as possible. In addition, the question of whether the outdoor- and exhaust air ducts should be routed outside or inside must be clarified. According to this, the device position next to the window is to be preferred in the context of a complete renovation with ETICS and window replacement, and installation can be simplified and accelerated with the help of prefabricated installation frames. The option of a heat exchanger in the core hole, on the other hand, remains a solution if the ventilation is to be installed after the renovation of the building envelope.
